Full textAbstract:
Prescribed fire is a tool used to manage vegetation in southern California. The nature and quan tity of gaseous and particulate emissions have not been described for California chaparral. A study examining carbon monoxide (CO), carbon dioxide (CO2), and par ticulate matter emissions from fuel beds constructed from common chaparral shrubs was initiated. Chamise (Adenostoma fasciculatum), ceanothus (Ceanothus crassifolius), manzanita (Arctostaphylos glandulosa), and scrub oak (Quercus dumosa) fuel beds were burned in December 1989, and March, May, and August, 1990. Gas and particulate matter samples were collected from 45 fires. Emission factors for CO2 and particulate matter were affected by species and month individually; month and species interacted and affected CO emission factors. Pearson's correlation coefficient and Kendall's tau indi cated that emission factors for CO and particulate matter were inversely related to combustion efficiency.

Abstract Currently, Indonesia has committed to achieve Net Zero Emissions (NZE) efforts on their Nationally Determined Contribution (NDCs) and at the same time focusing on air pollution abatement. One of the dominant emissions sources of particulate matter as well as Greenhouse Gases (GHGs) is from coal fired power plants. It contributes 50% to the total energy consumption in power generation, therefore the major power plant in Indonesia. Therefore, efforts to reduce GHGs and particulate emissions are needed to achieve the NZE target as well as to improve air quality. The research objective is to determine the particulate pollution load based on the Business as Usual (BaU) scenario and also under the emission reduction scenario for the year of 2030. Particulate pollution load was calculated using the emissions inventory methodology described in the brown cloud atmosphere workbook (ABC-EIM). Particulate emission reduction scenarios were developed using the assumption of full installation of Electrostatic Precipitator (ESP) technology to control PM emission. In 2030, the emission reductions PM10, PM2.5, Black Carbon (BC), and Organic Carbon (OC) are 57,854 ton/year, 57,854 ton/year, 432 ton/year, and 1,723 ton/year.

Compliance with modern environmental norms and regulations is an increasingly important requirement in the shipbuilding process of ship design and construction. Related to the ship production process, volatile organic compounds (VOCs), nitric oxides and particulate matter are the main emissions of harmful gases in the shipyard. This paper analyzes air emissions from the ship production process in a shipyard. Air emissions are quantified from either in-situ measurements from emission sources, or by materials that are used in the shipbuilding process, and the acquired data from those measurements is calculated as yearly emissions. Emission quantities of VOCs, nitric oxides, carbon dioxide, carbon monoxide and particulates are analyzed regarding possible reduction techniques considering efficiency and investment costs for using these methods. In conclusion, the best available and feasible emission reduction methods are suggested, and a suggestion for achieving the goal of a net zero emission shipyard.

Full textAbstract:
In recent years, frequent open biomass burning (OBB) activities such as agricultural residue burning and forest fires have led to severe air pollution and carbon emissions across South and Southeast Asia (SSEA). We selected this area as our study area and divided it into two sub-regions based on climate characteristics and geographical location: the South Asian Subcontinent (SEAS), which includes India, Laos, Thailand, Cambodia, etc., and Equatorial Asia (EQAS), which includes Indonesia, Malaysia, etc. However, existing methods—primarily emission inventories relying on burned area, fuel load, and emission factors—often lack accuracy and temporal resolution for capturing fire dynamics. Therefore, in this study, we employed high-resolution fire point data from China’s Feng Yun-4A (FY-4A) geostationary satellite and the Fire Radiative Power (FRP) method to construct a daily OBB emission inventory at a 5 km resolution in this region for 2020–2022. The results show that the average annual emissions of carbon (C), carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), non-methane organic gases (NMOGs), hydrogen (H2), nitrogen oxide (NOX), sulfur dioxide (SO2), fine particulate matter (PM2.5), total particulate matter (TPM), total particulate carbon (TPC), organic carbon (OC), black carbon (BC), ammonia (NH3), nitric oxide (NO), nitrogen dioxide (NO2), non-methane hydrocarbons (NMHCs), and particulate matter ≤ 10 μm (PM10) are 178.39, 598.10, 33.11, 1.44, 4.77, 0.81, 1.02, 0.28, 3.47, 5.58, 2.29, 2.34, 0.24, 0.58, 0.43, 0.99, 1.87, and 3.84 Tg/a, respectively. Taking C emission as an example, 90% of SSEA’s emissions come from SEAS, especially concentrated in Laos and western Thailand. Due to the La Niña climate anomaly in 2021, emissions surged, while EQAS showed continuous annual growth at 16.7%. Forest and woodland fires were the dominant sources, accounting for over 85% of total emissions. Compared with datasets such as the Global Fire Emissions Database (GFED) and the Global Fire Assimilation System (GFAS), FY-4A showed stronger sensitivity and regional adaptability, especially in SEAS. This work provides a robust dataset for carbon source identification, air quality modeling, and regional pollution control strategies.

Full textAbstract:
The analysis of real-world emissions is necessary to reduce the emissions of vehicles during on-road driving. In this paper, the matrix of gasoline direct injection passenger cars is applied to analyze the real-world emissions. The results show that high acceleration and high speed conditions are major conditions for the particulate number emissions, and the particulate number emissions are positively correlated with torque and throttle opening. The catalyst temperature and saturation are important factors that affect nitrogen oxide emission. The nitrogen oxide emissions of low speed and low torque conditions cannot be ignored in real-world driving. The carbon dioxide emissions are positively correlated with acceleration, torque and throttle opening. Once the vehicles are in the acceleration condition, the carbon dioxide emissions increase rapidly. The vehicles with higher average emission factors are more susceptible to driving behaviors, and the differences in the emission factors are more obvious, leading to an increase in the difficulty of emission control.

Full textAbstract:
The differences in the pollutant emissions from the combustion of bituminous coal and biofuels (wood, straw, and miscanthus pellets) under real-world boiler operating conditions were investigated. The experiments were performed on an experimental installation that comprised an 18 kW boiler, used in domestic central heating systems, equipped with a retort furnace, an automatic fuel feeder, a combustion air fan, and a fuel storage bin. The emission factors of gaseous pollutants, particulate matter, organic carbon, elemental carbon, and polycyclic aromatic hydrocarbons (PAHs), as well as some PAH concentration ratios for coal and biofuel combustion, were determined. The obtained results indicate that fuel properties have a strong influence on the emission factors of gaseous and carbonaceous pollutants. The total particulate matter (PM) emissions from the biofuel combustion were about 5-fold lower than those from the coal burned in the same boiler. The emission factors of the total carbons from the biofuel combustion were between 10 and 20 times lower than those from the coal combustion. The mean organic carbon (OC) and elemental carbon (EC) emission factors, based on the burned fuel, were 161–232 and 42–221 mg/kg for the biofuels and 1264 and 3410 g/kg for the coal, respectively. The obtained results indicate that molecular diagnostic ratios, based on the concentration of PAHs, vary significantly, depending on the fuel type.

Full textAbstract:
The paper presents results of considerations on the repeatability of the passenger car test results obtained in the WLTP procedure on a chassis dynamometer. The research concerned the aspects of exhaust emissions and fuel consumption. Measurements were carried out in the WLTC test with a cold engine start and then in four WLTC (Worldwide harmonized Light vehicles Test Cycle) tests with a hot engine start. The following values were measured: average specific distance emissions of hydrocarbons, non-methane hydrocarbons, carbon monoxide, nitrogen oxides, particulate matter and carbon dioxide, specific distance particulate number, and operational fuel consumption. Thus, it was possible to assess the impact of the engine's thermal state at start-up on the test results and the nature of test results repeatability with the start-up of a hot engine. The repeatability of the test results was assessed based on the coefficient of variation obtained in the individual tests and the relationship of the maximum difference between measurement results values in the individual tests for a hot engine start. The obtained test results turned out to be very diverse for the considered parameters and indicated low repeatability. Values of carbon dioxide emissions and operational fuel consumption were definitely the least varied in individual hot engine start tests. The exhaust emission of particulate matter varied the most in individual test iterations. However, the specific distance particulate number was relatively similar between individual tests, less so than the exhaust emission of other pollutants. In the case of different engine thermal state at start-up, the emitted particulate number varied the most in the test results, while the emission of carbon dioxide and operational fuel consumption varied the least. The repeatability of executing the velocity process in WLTC tests at hot engine and cold engine start-up was also examined as processes determining exhaust emissions and fuel consumption. These tests were much more repeatable than the exhaust emission and fuel consumption.

Full textAbstract:
The present paper proposes an original approach to estimate gaseous and particulate emissions from boreal forest fires based on the Canadian Forest Fire Behaviour Prediction (FBP) System. The FBP System permits calculation of fuel consumption and rate of spread for individual fires on an hourly basis from meteorological conditions and fuel patterns. Weather data are obtained by running the Canadian weather forecast model GEM (Global Environmental Multiscale). Hourly emission point sources can then be generated from a given wildfire database. The smoke emission model was first applied to the boreal forest fires in Quebec in the summer of 2002. Geographical distribution and temporal variability of emission amounts, as well as injection heights, were assessed hourly. In July, ~150 wildfires released 39 Mt of CO2 equivalent of greenhouse gases and 470 kt of fine particulate matter to the atmosphere. They contributed 32 and 5% of Quebec’s and Canada’s annual greenhouse gas emissions, respectively. Black carbon was estimated to account for 4% of the total fine particulate matter. Wildfires were responsible for 51 and 90% of all Canada’s black carbon and particulate organic matter sources, respectively.

Full textAbstract:
This paper presents a novel machine learning methodology able to extend the results of detailed local emission inventories to larger domains where emission estimates are not available. The first part of this work consists in the development of an emission inventory of elemental carbon (EC), black carbon (BC), organic carbon (OC), and levoglucosan (LG) obtained from the detailed emission estimates available from the Project LIFE PREPAIR for the Po Basin in north Italy. The emissions of these chemical species in combination with particulate primary emissions and gaseous precursors are very important information in source apportionment and in the impact assessment of the different emission sources in air quality. To gain a better understanding of the origins of atmospheric pollution, it is possible to combine measurements with emission estimates for the particulate matter fractions known as EC, BC, OC, and LG. To identify the sources of emissions, it is usual practice to use the ratio of the measured EC, OC, TC (Total Carbon), and LG. The PREPAIR emission estimates and these new calculations are then used to train the Random Forest (RF) algorithm, considering a large array of local variables, such as taxes, the characteristics of urbanization and dwellings, the number of employees detailed for economic activities, occupation levels and land cover. The outcome of the comparison of the predictions of the machine learning implemented model (ML) with the estimates obtained for the same areas by two independent methods, local disaggregation of the national emission inventory and Copernicus Air Modelling Service (CAMS) emissions estimates, is extremely encouraging and confirms it also as a promising approach in terms of effort saving. The implemented modelling approach identifies the most important variables affecting the spatialization of different pollutants in agreement with the main emission source characteristics and is suitable for harmonization of the results of different local emission inventories with national emission reporting.

Full textAbstract:
Indoor air quality is a growing concern in the world. People spend a considerable amount of time in indoor environments such as homes, workplaces, shopping malls, stores, and so on. Indoor sources like incense and candle burning, cooking contribute a significant amount of indoor air pollutants such as particulate matter, carbon monoxide (CO), volatile organic compounds. Exposure to these kinds of pollutants can result in adverse health effects.
The purpose of this research is to determine the particulate matter and carbon monoxide emission factors (EFs) from incense stick burning. A test chamber with a rectangular exhaust duct, a fan to exhaust air with pollutants in it, and pollutant sensors were used to achieve the project goals. Several experiments were performed with different cases/scenarios to accurately estimate the EFs and several test runs were conducted for each case to test the repeatability of the results.
The CO, PM2.5 (mass), PM2.5 (number), PM10 (mass), PM10 (number) EFs developed in this research are between 110-120 mg/g of incense, 2.5-3 mg/g of incense, 800-1100 #particles/µg of incense, 32-33 mg/g of incense, 1200-1400 #particles/µg of incense respectively.

Full textAbstract:
Black carbon (BC) and polycyclic aromatic hydrocarbons (PAHs) are two atmospheric pollutants produced by motor vehicles using carbonaceous fuels. As a part of the Mexico City Project, measurements of BC, PPAHs and many other gas- and particle-phase emissions were measured in Mexico City using a mobile laboratory during the Mexico City Metropolitan Area field campaign in April 2003 (MCMA-2003). The main goal of this research is to estimate emissions of BC and particulate PAHs (PPAHs) for Mexico Cityâ s vehicle fleet. The emissions of gas-phase pollutants such as carbon monoxide (CO), total nitrogen oxides (NOy) and volatile organic compounds (VOC) are also estimated. The mobile lab has previously been used to chase vehicles and measure their emissions, but analysis has traditionally focused on determining emission factors of individual vehicles associated with specific chasing events. The laboratory continuously samples ambient air from an inlet at the front of the van, and it is always â seeingâ exhaust plumes from the vehicles around it while driving through traffic. We have developed an algorithm that automatically identifies the exhaust plume measurement points, which are then used as the basis for calculation of emission factors. In the nearly 90 hours of on-road sampling during the field campaign, we have identified ~30,000 exhaust measurement points. The large sample size enables us to estimate fleet-average emission factors and thus the emission inventory. Motor vehicles are estimated to emit annually 1,960 tons of BC, 56.2 tons of PPAHs, 1,320,000 tons of CO, 125,000 tons of NOy and 2440 tons of VOCs. The spatial and temporal patterns of BC and PPAHs in different locations with in MCMA are also studied.<br>Master of Science

Air quality management strategies in the US are developed largely from estimates of emissions, some highly uncertain, rather than actual measurements. Improved knowledge based on measurements of real-world emissions is needed to increase the effectiveness of these strategies. Consequently, the objectives of this research were to (1) quantify relationships among urban emissions sources, land use, and demographics, (2) determine the spatial and temporal variability of emissions, and (3) evaluate the accuracy of official emissions estimates.
These objectives guided three field campaigns that employed a unique mobile laboratory equipped to measure pollutant fluxes by eddy covariance. The first campaign, conducted in Norfolk, Virginia, represented the first time fluxes of nitrogen oxides (NOx) were measured by eddy covariance in an urban environment. Fluxes agreed to within 10% of estimates in the National Emissions Inventory (NEI), but were three times higher than those of an inventory used for air quality modeling and planning. Additionally, measured fluxes were correlated with road density and increased development.
The second campaign took place in the Tijuana-San Diego border region. Distinct spatial differences in fluxes of carbon dioxide (CO2), NOx, and particles were revealed across four sampling locations with the lowest fluxes occurring in a residential neighborhood and the highest ones at a port of entry characterized by heavy motor vehicle traffic. Additionally, observed emissions of NOx and carbon monoxide were significantly higher than those in emissions inventories, suggesting the need for further refinement of the inventories.
The third campaign focused on emissions at a regional airport in Roanoke, Virginia. NOx and particle number emissions indices (EIs) were calculated for aircraft, in terms of grams of pollutant emitted per kilogram of fuel burned. Observed NOx EIs were ~20% lower than those in an international databank. NOx EIs from takeoffs were significantly higher than those from
taxiing, but relative differences for particle EIs were mixed. Observed NOx fluxes at the airport agreed to within 25% of estimates derived from the NEI.
The results of this research will provide greater knowledge of urban impacts to air quality and will improve associated management strategies through increased accuracy of official emissions estimates.<br>Ph. D.

Full textAbstract:
This investigation aims to enhance the regeneration performance of a diesel particulate filter. This is achieved by introducing various chemical components to the regeneration process, which are representative of what can be generated ‘on board’ a vehicle using an exhaust gas fuel reformer. By researching the effects of introducing such components using a periodic injection cycle the aim is to reduce the volume of ‘reformates’ required to assist in proficient diesel particulate filter regeneration. As a result, this study also aims to support future work in the development of exhaust gas fuel reformer design for DPF aftertreatment applications. All experiments were performed using a Ford Puma 2.0 litre diesel engine. A test rig was constructed and installed that featured a mini diesel particulate filter housed within a tubular furnace. Exhaust gas could be sampled directly from the exhaust manifold and fed through the DPF. Exhaust gas measurements were taken both pre and post DPF using a FTIR spectrometer. It was shown that the regeneration process could be supported substantially by the introduction of hydrogen. Similar properties were also demonstrated when introducing a hydrogen-carbon monoxide mixture. The introduction of these species allowed for the regeneration process to be implemented at filter temperatures substantially lower than the passive regeneration temperature. Furthermore, by introducing these simulated reformates using a periodic injection strategy, it was evident that similar benefits to the regeneration process could be attained with significantly less volumes of simulated reformates. In an attempt to effectively utilise the carbon monoxide generated during hydrogen production by an exhaust gas fuel reformer, this study defined an optimised hydrogen/carbon monoxide mixture ratio of 60% (v/v) hydrogen balanced with carbon monoxide. At this optimised mixture ratio, the filter demonstrated the highest regeneration efficiency of all ratios tested. Such data could be utilised in future work in the development of fuel reformer design.

Full textAbstract:
Diesel Particulate Matter (DPM) and coal dust samples were characterised using Raman microscopy, X-ray Photoelectron Spectroscopy (XPS), Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS), Thermo-Gravimetric Analysis (TGA), X-ray Fluorescence (XRF) spectrometry and Scanning electron Microscopy. The sp2/sp3 carbon bonding ratios for DPM and coal dust were determined as 6.1 and 0.7, respectively, from XPS. Principal Component Analysis (PCA) was successfully implemented as a tool for distinguishing between the very similar DPM and coal dust Raman spectra, with over 99% of the variance contained in the first principal component. DPM and coal dust mixtures with known compositions were produced. Raman instrumental parameters were systematically optimised by varying the objective lenses, acquisition times and laser powers, to improve spectral and obtain the most reproducible integrated spectral areas. A rotation stage was developed and employed to spin the specimens during analysis, resulting in a larger sampling area. This resulted in a more representative sampling regime for the heterogeneous specimens and a considerable improvement in the reproducibility of integrated spectral areas. The error in the integrated spectral areas of 10 replicate spectra of different mixtures ranged from 5-22% before implementation of the rotating stage and was notably reduced to 2 -6% due to the action of spinning. Raman spectra of mixtures were used to construct a Partial Least Squares (PLS) model. The R2 values for the DPM and coal dust were 0.865 and 0.763, respectively. The differential bum-off of volatile organics during the Raman analysis due to localised heating from the laser hindered the ability to gain highly reproducible spectra and thus markedly affected the PLS model. A method development stage aimed at improving the R2 values was applied to the samples. This involved heat-treating the specimens to 625°C in an inert nitrogen atmosphere, before the Raman analysis. The resultant PLS model, after heat-treatment, dramatically improved the R2 values such that the DPM and coal dust were 0.974 and 0.907, respectively. This model was used to predict the composition of a test sample with known amounts of DPM and coal dust. The concentrations predicted by the model were 166 ± 3.9pg for the DPM and 68 ± 7.8jxg for the coal dust. The model slightly overestimated the amount of DPM present in the sample but gave a large underestimation of the coal dust content. The diagnostics of the model were investigated and recommendations for the improvement of future models were given.

Aerosol emissions from diesel combustion and other activities in rail yards can affect the health of urban populations. Fine particulate (PM[subscript 2.5]) concentrations near the Inman and Tilford rail yards in Atlanta, Georgia, are the highest measured in the state. The rail yard complex is surrounded by homes, schools, businesses and other industries. The impact of the aerosol emissions from these rail yards on local concentrations of PM[subscript 2.5] was quantified. Specifically, black carbon and PM[subscript 2.5] fuel-based emission factors from the rail yards were estimated by carbon balance using high time-resolution monitoring, a BC and PM[subscript 2.5] emissions inventory was estimated and dispersion modeling was applied to assess the impact of the rail yard activities on local air quality and the cost and benefits of upgrading locomotive engines with cleaner technologies was assessed. Further, baseline information that will allow a later evaluation of the improvement of local air quality as locomotives operating in the rail yards are upgraded was generated, and a composition profile of the rail yard aerosols was developed using chemical speciation techniques. These results found that activities from locomotives in the Inman and Tilford Rail yards lead to and an average emission factor of 6.0 ± 0.5 g of PM[subscript 2.5] per gallon of fuel and are responsible for increases in annual average concentrations of approximately 1.3 µg/m³ of PM[subscript 2.5] as far as 1 km from the perimeter of the rail yard complex. Approximately 11.7 tons of BC and 26 tons of PM[subscript 2.5] per year were emitted from the rail yards in 2011. The rail yards were found to be important sources of hydrocarbon-like organic aerosols (HOA) and black carbon from fuel (BCf). Upgrading the engines at the rail yards would decrease PM[subscript 2.5] emissions by about 9 t/year, reducing PM[subscript 2.5] concentrations around 0.5±0.1 µg/m³ as far as 1 km from the perimeter of the rail yard complex and producing monetized health benefits of approximately 24 million dollars per year.

La compréhension du rôle des aérosols atmosphériques dans le fonctionnement du système terre-atmosphère est limitée par les incertitudes sur leur répartition spatiale, leur composition et leurs sources. Si leurs impacts sur le changement climatique et l’environnement peuvent être évalués grâce aux modèles de chimie-transport, ces incertitudes en limitent la précision. Les observations satellitaires ont la capacité de fournir à l’échelle globale des informations précises sur un certain nombre de paramètres « aérosols » mais elles sont limitées par les conditions nuageuses, la périodicité des orbites et par le contenu en information, c’est-à-dire le type de paramètres que l’on peut retrouver suivant la nature de ces observations. Une approche prometteuse consiste à améliorer les champs d’émission des modèles en utilisant le principe de la modélisation inverse. Dans cette étude, nous avons conçu une méthode de restitution simultanée des sources d’émission de poussières désertiques, de carbone suie et de carbone organique à partir des produits satellitaires (POLDER/PARASOL) dérivés en utilisant l’algorithme GRASP, conjointement à une modélisation inverse du modèle GEOS-Chem. Cela nous a permis de créer une base de données d’émissions globales d’aérosols sur la période 2006 – 2011. Des simulations réalisées avec les modèles directs GEOS-Chem et GEOS-5/GOCART utilisant cette base de données montrent bien entendu un bon accord avec des observations POLDER mais aussi une nette amélioration de la modélisation de l’aérosol à l’échelle globale lorsque l’on compare les sorties à des mesures indépendantes du réseau AERONET ou à d’autres mesures spatiales (MODIS, MISR, OMI)<br>Understanding of the role that atmospheric aerosol play in the Earth-atmosphere system is limited by uncertainties in aerosol distribution, composition and sources. Thus, accurate chemical transport model simulation systems are crucial needed to analyse and predict atmospheric aerosols and their impacts on climate change and environment. Satellite observations have ability to provide an extensive spatial coverage and accurate aerosol products, however, are constrained by clear-sky condition, global coverage orbit cycle and information content. One of the most promising approaches is to reduce model uncertainty by improving the aerosol emission fields (i.e., model input) by means of inverse modeling relying on satellite observations as a constrain. In this study, we designed a method of simultaneous retrievals of desert dust, black carbon and organic carbon aerosol emission sources using aerosol data obtained from GRASP algorithm applied to POLDER/PARASOL satellite observations, and relying on the GEOS-Chem inverse modeling framework. Then, a satellite-based global aerosol emission database (2006-2011) has been developed. This aerosol emission database has been further evaluated by utilization in GEOS-Chem and GEOS-5/GOCART models. The model posterior simulation of aerosol properties employing the retrieved emissions shows a better agreement than the model prior simulation; it is true for not only fitted PARASOL products, but also for completely independent measurements from ground-based AERONET and satellites aerosol products (e.g., MODIS, MISR, OMI). The results suggest that the satellite-based aerosol emission database improves overall global aerosol modeling

First and foremost, the nature of the fuel has a direct impact on the composition of the particulate matter and gaseous particles formed as the combustion products. Woody, Grass, or leafy fuels have been found to be composed of different compounds with different mass fractions. For example, cellulose content in wood is higher than other types of biomass fuel. As a results, it is logical to seek similar compound ending up in the particulate matter. The scale and intensity of the fire is the other influential factor. Although the effect of natural wildfire (bushfire) smoke particles would not be as direct and immediate as those evolving from the fuel burnt in household uses, long term effect of exposure to these particles spreading within the atmosphere month and even years after the fire has happened should not be overlooked. Besides, in very close vicinities to the fires, in fresh smoke less than minutes old, there always exist high number of finer particles which are health-wise of more concern compared to larger particle (as these finer particles penetrate into lower parts of the respiratory system through diffusion). Weather conditions, like elevation, wind speed, humidity, and sunlight are also influential factors in the formation of these particles. The other crucial factor is the phase of burning, i.e. Ignition, flaming, mixed state, and smouldering. Numerous studies have investigated the effect of these conditions on the size distribution, number concentration and physiochemical properties of smoke particles.
PM properties of BB smoke have been investigated all around the globe for different biomass types and different burning conditions. Black carbon (BC) and organic carbon (OC) content of the PM are the most documented investigated items as they contributes to the high mass percentage of the PM. Other ubiquitous PM components include anhydrosugars, alcohols, PAHs, acids, water soluble ions, and trace elements. Gaseous particles resulted from BB carry with them sulphur oxides (SOx) and nitrogen oxides (NOx), volatile and semi volatile organic compounds. Each of these compounds and materials are known to have serious health and climate impacts.
Numerous studies have used different devices and technologies to investigate the effect of fuel type and amount, and phase of burning and operational mode on different properties of fresh and aged smokes in case of small scale controlled or laboratory burns, massive natural wildfires, or air-forced cook stove gasifiers.
In Australia, despite contributing to more than 7% of biomass burning emissions annually, there are quite a few exhaustive studies on the properties of bushfire particles. The importance of research redoubles considering the mega-fires taking place in Australia 2019-2020 which ravaged an estimate of 19 million hectares. This study is aimed to make a contribution in filling this gap and finding novel ideas in order to investigate different factors influencing Australian local vegetation fires which could potentially effect the environment and human health. Three journal articles are published based on this study, parts of which are used in different sections throughout this report. Citations are made in the beginning of the main relevant chapters. Abstract summaries are presented briefly here: First paper: Under controlled laboratory settings and small scale fires of vegetation collected from Toohey forest, it was found that leaves classification burn with flaming dominant phases producing intense black smoke which is consisted of larger particles as opposed to more smouldering-dominant burning of the branch and grass classifications releasing white smoke emissions which contain finer particles. Elemental analysis detected nine main elements in all three classifications and in three size fractions of smoke particulate matter samples (from 14.1μm to below 2.5μm). Potassium, a biomarker, was the most prevalent element among the samples followed by sulphur. Less abundant elements were found to be Na, Al, Mg, Zn, Si, Ca, and Fe.
Second paper: Particle size distribution in biomass smoke was observed for different burning phases, including flaming and smouldering, during the combustion of nine common South Queensland Australian vegetation representatives. Smoke particles generated during smouldering phase of combustions were found to be coarser as compared to flaming aerosols for all hard species. In contrast, for leafy species this trend was inversed. In addition, the combustion process was investigated over the entire duration of burning by acquiring every second data for all nine species. Particles were separately characterised in two categories: fine particles (diameter below 200nm), and course particles with the diameter larger than 200nm. It was found that fine particles contribute to more than 90 percent of the total fresh smoke particles for all investigated species.
Third paper: smoke samples were collected during prescribed fire burns conducted between May 2018 and August 2019across different regions in Toohey forest, Queensland, Australia. Particle size/mass distribution as well as size-segregated elemental content were measured and the results were compared against the values obtained from the combustion of similar vegetation mixture under controlled laboratory settings. It was found that the concentration levels of coarse particles (sizes above 1 μm) were higher during field burn events, whereas the contributions of PM1 (smaller than 1 μm) was higher in case of laboratory burns. Following elemental analysis of different size classes of smoke particles (<0.96μm, 0.96-2.5μm, and >2.5μm) confirmed the presence of eight elements in both laboratory and field cases (Na, K, Mg, Ca, Zn, Al, Fe, S), however, levels of Ca, Mg, Al, and S were noticeably higher in prescribed fire results. Observed discrepancies between field and laboratory data could be attributed to the effect of top soil and duff layers present in prescribed fires/natural wildfires and absence thereof in the laboratory burns, which reveals the influential role of the aforementioned layers on the overall air quality status across bushfires-affected areas.<br>Thesis (PhD Doctorate)<br>Doctor of Philosophy (PhD)<br>School of Eng & Built Env<br>Science, Environment, Engineering and Technology<br>Full Text

Before being able to correctly classify carbon units (the object of trade in emissions trading schemes) under international economic law, their inherent qualities and characteristics need to be understood. This requires a factual assessment of their qualities and characteristics, which will provide the evidence necessary to determine their proper legal classification under international economic law. In particular, Chapter 3 considers the historical and policy origins of emissions trading schemes and the key attributes and nature of carbon units, such as how they are created, what they represent, how they may be used, and how they derive value. The legal classification of carbon units under the different domestic jurisdictions is also surveyed.

Full textAbstract:
Having determined that carbon units are, to varying extents, subject to international economic law, Chapter 8 assesses the consistency of emissions trading schemes and their rules affecting carbon units with that body of law. In particular, Chapter 8 identifies and evaluates the rules in emissions trading schemes affecting the trade, use, and value of carbon units that constitute prima facie violations of that body of law. It considers: (i) the differential treatment of carbon units that engages disciplines on non-discrimination; (ii) the quantitative restrictions on external carbon units that engage disciplines on market access; and (iii) the kinds of governmental interference in carbon markets that engage disciplines on investment. Chapter 8 thereby identifies and catalogues numerous prima facie breaches embedded in the rules of most emissions trading schemes.

Full textAbstract:
This book assesses whether—and how—emissions trading schemes are subject to international economic law. Through an analysis of trade and investment treaties and related jurisprudence, it argues that the objects of trade in these schemes, namely carbon units (also known as emissions permits or carbon credits), are capable of being legally characterized as ‘goods’, ‘services’, ‘financial services’, and ‘investments’ under international economic law. The sui generis properties of carbon units—such as their intangibility, their degree of permanence, their relationship to an economic activity performed, and their use as a regulatory instrument—make this a particularly complex question. Having ascertained whether and how carbon units are regulated in this regard, this book undertakes a comparative analysis of numerous emissions trading schemes and uncovers a raft of design elements affecting trade and investment in carbon units that could be impugned under international economic law. In particular, it demonstrates how all of the major schemes—from the nascent schemes in China, South Korea, and Ontario to the more established schemes in the European Union, Switzerland, New Zealand, Norway, California, and Quebec—engage in violations of international economic law that are, in many cases, unlikely to be justified under environmental or other exceptions or exemptions. Not only do these conclusions have implications for the relationship between the international economic and international climate regimes but, more broadly, these conclusions interrogate the efficacy of international economic law for covering market-based mechanisms designed to manage environmental problems. They also provide guidance to policy-makers seeking to inoculate their emissions trading schemes from legal challenges under international trade and investment treaties.

Full textAbstract:
This is an advance summary of a forthcoming article in the Oxford Research Encyclopedia of Climate Science. Please check back later for the full article.Africa, a continent with the largest number of countries falling under the category of Least Developed Countries (LDCs), remains highly dependent on rain-fed agriculture that suffers from low intake of water, exacerbating the vulnerability to climate variability and anthropogenic climate change. The increasing frequency and severity of climate extremes impose major strains on the economies of these countries. The loss of livelihoods due to interaction of climate change with existing stressors is elevating internal and cross-border migration. The continent is experiencing rapid urbanization, and its cities represent the most vulnerable locations to climate change due in part to incapacitated local governance. Overall, the institutional capacity to coordinate, regulate, and facilitate development in Africa is weak. The general public is less empowered to hold government accountable. The rule of law, media, and other watchdog organizations, and systems of checks and balances are constrained in different ways, contributing to poor governance and resulting in low capacity to respond to climate risks.As a result, climate policy and governance are inseparable in Africa, and capacitating the government is as essential as establishing climate policy. With the highest level of vulnerability to climate change compared with the rest of the world, governance in Africa is pivotal in crafting and implementing viable climate policies.It is indisputable that African climate policy should focus first and foremost on adaptation to climate change. It is pertinent, therefore, to assess Africa’s governance ability to identify and address the continent’s needs for adaptation. One key aspect of effective climate policy is access to up-to-date and contextually relevant information that encompasses indigenous knowledge. African countries have endeavored to meet international requirements for reports such as the National Communications on Climate Change Impacts and Vulnerabilities and the National Adaptation Programmes of Action (NAPAs). However, the capacity to deliver on-time quality reports is lacking; also the implementation, in particular integration of adaptation plans into the overall development agenda, remains a challenge. There are a few successes, but overall adaptation operates mainly at project level. Furthermore, the capacity to access and effectively utilize availed international resources, such as extra funding or technology transfer, is limited in Africa.While the continent is an insignificant source of emissions on a global scale, a more forward looking climate policy would require integrating adaptation with mitigation to put in place a foundation for transformation of the development agenda, towards a low carbon driven economy. Such a futuristic approach calls for a comprehensive and robust climate policy governance that goes beyond climate to embrace the Sustainable Development Goals Agenda 2030. Both governance and climate policy in Africa will need to be viewed broadly, encompassing the process of globalization, which has paved the way to a new geological epoch, the Anthropocene. The question is, what should be the focus of climate policy and governance across Africa under the Anthropocene era?

Abstract A good coordination of traffic signals can reduce waiting times, the number of stops and accelerations, and thus increase travel speeds, which can lead to a reduction in fuel consumption and air pollutant emissions. To investigate the effects of traffic signal coordination on traffic and emission parameters, simulation studies are advantageous over time-consuming field tests to quantify and evaluate quickly, safely and cost-effectively a large number of different input variables, such as intersection distances, traffic volumes and different signal control configurations. This paper describes the findings of an extensive simulation study in which a microscopic traffic flow simulation model was coupled with an emission model. Through the simulation of a range of scenarios, the model is used to investigate the influence of inter alia traffic volume, signal coordination schemes and signal parameters on carbon dioxide, nitrogen oxides and particulate matter emissions along an arterial road equipped with a series of traffic lights. Results showed that shorter distances between the signalized intersections led to about 20% higher emission values. Furthermore, different cycle times and their effects on emissions were investigated, whereby higher cycle times led to lower values of about 14% less emissions.

AbstractSouth Africa range 15th as the world largest CO2 emitter contributing to 1.2% of global emission. During the Kyoto Protocol of 2014, South Africa pledged to reduce its emission by 34% and 42% in 2020 and 2025 respectively. This study is a combination of literature review from South Africa with particular emphasis on road transport. The focus was on vehicle emission with reference to Limpopo Province to demonstrate how emissions from primarily the use of diesel and petrol as one of the major contributors to CO2 emission in the province are vital for the sustainability debate. The methodology used to illustrate the dangers of vehicular emissions were based on statistical estimates from the Department of Environmental Affairs (DEA) inventory report from 2000 to 2010. The information used in assessing the vehicle emission standards in Limpopo were obtained from DEA. The findings from literature reviews in general and the results from the field survey from Limpopo Province shed some light on South Africa's vehicle emissions policy issues and standards. Also the analysis focused on the impact of vehicular fleet management and carbon emissions. The article concludes by drilling down to vehicle users, motor vehicle repairs, engine over haulers, used engine collection and disposal with respect to their roles in vehicle emission and control in South Africa.

AbstractBy the Sixth IPPC Report issued in August 2021, man-made greenhouse gases emission is responsible for approximately 1.1 °C of warming between 1850 and 1900, and the global temperature is expected to reach or exceed 1.5 °C by 2041. The IPPC thus urges world leaders to adopt substantial and sustained reductions to reduce carbon dioxide (CO2) and other greenhouse gas emissions to stabilize global temperature by the next 20–30 years. In East Asia, the Former Prime Minister of Japan, Yoshihide Suga, declared that Japan will become carbon–neutral by 2050. The commitment has been further endorsed by his successor Prime Minister Kishida Fumio. Korea enacted the Carbon Neutrality Act, which requires the government to cut greenhouse gas emissions in 2030 by 35% or more from the 2018 levels in August 2021. In China, President Xi Jinping committed to achieving carbon neutrality by 2060 at the U.N. General Assembly in September 2020. In Taiwan, President Tsai Ing-wen announced on April 22, 2021, that Taiwan will achieve carbon neutrality by 2050. The road to achieving net-zero emissions is an ambitious but challenging goal for each significant GHGs emitter in the Asia–Pacific region. Each country has its own economic, social, and technological foundation and capabilities and thus requires different approaches to achieve the same goal. This chapter explores the recent global trends with particular references to EU, U.S., and Japan’s law and policy development aiming to achieve carbon neutrality goals by 2050.

Full textAbstract:
AbstractThe construction industry in Bangladesh is actively pursuing the goal of preserving the equilibrium between the amount of greenhouse gases (GHGs) produced and expelled from the atmosphere. An ideal way to reduce CO2 emissions from concrete production is the utilization of industrial by-products like class F fly ash, slag, etc. as supplementary cementitious materials (SCMs). On the other hand, reducing the life cycle cost (LCC) through the extension of service life could also be an effective way to reduce the overall carbon footprint of any RC infrastructure, particularly in saline exposure. Higher service life ensures lesser repair work for a corroded marine RC element and eventually results in reduced CO2 emission in the lifetime. Therefore, it is evident that producing concrete with proper proportions of SCMs and other mix parameters to achieve the desired service life can reduce both the initial and long-term carbon emission potential of an RC structure in saline exposures. With this end in view, a case study is presented where concrete mixes have been prepared using different binder types (both customized and commercially available composite blends) for a particular design strength commonly used in Bangladesh. The service life and repair frequency of an RC element made of considered concrete mixes have been predicted through the electrical resistivity of the mixes. LIFE-365 software has been used for the analysis. It has been found that commercially available CEM III and the blended mix of CEM I with 30% slag plus 20% fly ash exhibited prolonged corrosion initiation time, least repair requirements during the service life of 100 -years and consequently, lower LCC and overall CO2 emissions as compared to other mixes used. The outcome of the study thus necessitates the inclusion of required policies and guidelines in local construction supply chains and practices to reduce embodied carbon of RC construction.

Full textAbstract:
Abstract The reduction of greenhouse gas (GHG) emissions from international aviation and shipping is a key priority for policymakers. The International Maritime Organization (IMO) has adopted its 2023 Greenhouse Gas Strategy and is working on the adoption of a carbon pricing instrument to decarbonize international shipping. Similarly, the European Union (EU) has extended its emission allowance trading scheme (ETS) to international shipping, while the International Civil Aviation Organization (ICAO) has adopted the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). CORSIA runs in parallel to the EU ETS to intra-EEA flights. The paper analyzes the approach taken by EU policymakers for the inclusion of aviation and shipping in the EU ETS. In particular, it discusses the regulated entities, exemptions, allowance types, geographical scope, GHG types, revenue use, fines, Monitoring Reporting and Verification (MRV) and allocation rules. By exploring the policy progress made in the two sectors and the lessons learnt from a cross-sectoral comparison of the market-based measures, this article provides valuable insights for policymakers, industry stakeholders, and other interested parties seeking to promote an effective and equitable energy transition in international aviation and shipping.

Full textAbstract:
AbstractFood is one of the most important components for the survival of humans. Women suffer the most impacts of the cooking harmful gases and particulate matters that are 2.5 microns (PM2.5) or less such as PM10. Improved cookstoves are used to reduce firewood consumption, lower the smoke released from the kitchen, help women improve their health, and conserve native trees in the area. Sustainably managed biomass, unlike the burning of fossil fuels, is considered carbon neutral since it does not contribute to the overall carbon emissions in the atmosphere. In 2015, the United Nation mentioned 17 Sustainable Development Goals (SDGs) to be achieved by 2030. This research aims to assess an improvement in the cookstove implementation level within the clean development, by reducing the carbon emissions following the Indian perspective for the program of better cookstoves.

Full textAbstract:
AbstractThis study describes a framework for optimizing environmental sustainability, climate resilience, and cost in post-hazard transport asset recovery. Particular focus is given to the environmental impact assessment component and its conceptual integration with resilience metrics. After describing the workflow adopted in the complete framework, the environmental impact modelling assumptions, system boundaries, and life cycle inventories for materials, on-site activities and transportation are detailed. Carbon equivalent emissions are evaluated for various restoration tasks for a bridge subjected to nine flood scenarios and represented through a sustainability index. A baseline environmental impact analysis is initially conducted, considering conventional materials, construction techniques, and procedures for each restoration task. Additional sensitivity studies are carried out to evaluate the influence of low-carbon solutions and task duration on carbon emissions. These are weighted based on the probability of the bridge being in a specific damage state. The results demonstrate that low-carbon solutions can provide carbon savings to varying degrees depending on the hazard intensity. Normalised sustainability, resilience, and cost metrics are combined into a unique global index, which can be adopted to prioritise the recovery of the asset. Suggestions on adopting circularity indicators and waste hierarchy levels into such frameworks are also given.

Full textAbstract:
Abstract Besides contributing to around 85% of the global GDP, G20 countries will play a critical role in setting the future path of urbanisation as they contributed to around 67% of the global urban population in 2023. Moreover, India and China are the two most populous G20 member countries housing the most populated megacities like New Delhi, Shanghai, Beijing, and Mumbai among others. Most of these megacities face challenges like congestion, housing shortage, unequal access to urban services, and unplanned growth. On the contrary, many European cities are experiencing population shrinkage without much reduction in their carbon footprint. Notably, G20 countries contribute to 80% of the global carbon emissions, owing to economic production, weak planning and policy structure, and ineffective environmental regulations. Also, sprawl development is common across them, and is a major contributor to carbon emissions. Previous G20 summits have already acknowledged the role of cities in the ‘race to zero’ and highlighted the critical role of the ‘circular economy’ in reducing carbon footprint. The UN Habitat has also identified strengthening of urban rural linkages to build sustainable habitats. In light of the above, this chapter aims to identify the global demographic trajectory and development challenges with particular reference to the G20 countries. It highlights deficiencies in planning ‘zero carbon cities’ and discusses the merits of Mission LiFE proposed by India as a tool to plan for carbon neutral cities and habitats. The chapter suggests that by adopting mindful consumption behaviour, the future urbanisation can be more sustainable and help the countries to be on track with the global goals.

Full textAbstract:
AbstractRice production significantly contributes to greenhouse gas emissions (GHGE), especially methane (CH4) emissions at various cropping stages. A major source of methane emissions is the decomposition of fertilizers and organic residues in flooded fields during the irrigation cycle. CORIGAP technologies and practices are mainly associated with closing yield gaps by increasing productivity and profitability but have been co-designed to address climatic challenges and to minimize negative environmental impacts. Therefore, over the last decade, the CORIGAP interventions not only helped to reduce yield gaps substantially but also resulted in a significant reduction of the carbon footprint (CF) in rice production. This chapter starts with an in-depth synthesis of scientific-based evidence and knowledge on challenges and constraints to reducing rice CF in CORIGAP countries. The chapter introduces solutions that have been proven to reduce GHGE, in particular, Alternate Wetting and Drying (AWD), rice-straw management, mechanization, and postharvest management. The latter two approaches include laser land leveling, mechanized direct seeding and transplanting, and paddy grain drying will be described in more detail. In addition, life cycle assessments will outline the quantification of the carbon footprint in rice production, for these specific technologies. The chapter presents three country case studies (Thailand, Indonesia, and Vietnam) from data collected through CORIGAP activities to estimate GHGE reductions associated with implementation of best practices for lowland irrigated rice production. Lastly, this chapter provides the outcomes related to GHGE reduction and offers specific recommendations that can be easily implemented in other countries.

Full textAbstract:
AbstractKenya is overly affected by the consequences of climate change and struggling to find ways to balance mitigation with the urgent need to meet the country’s infrastructure and housing needs. Traditional concreting methods, such as onsite mixing and manual compaction, are slow, material, water, and labor-intensive. The precast industry therefore offers a competitive alternative in terms of cost and environmental impact. When ordinary Portland cement is used, it is responsible for 80–90% of the carbon footprint of concrete. Hence, there is urgent need to minimize carbon emissions by using supplementary cementitious materials (SCMs) in concrete construction. Since cement factories are mostly located around the city of Nairobi, in other regions, the price of cement increases with transport distance. Precast concrete construction could become a lever for both lower prices and carbon emissions. Clinker reduction can take place at the cement plant or concrete mixing plant. Blending in the cement factory can produce more robust binder qualities but is limited to large SCM supply streams. Blending at the precast plant allows for tailored, smaller, local supply streams from industrial and agricultural by-products. The paper discusses the potential of using artificial intelligence to merge multiple small heterogeneous feed streams from renewable and recyclable resources into large homogeneous feed streams, with a particular focus on the use in precast concrete processing.

In the context of the urgent need to combat climate change, renewable energy sources, such as geothermal energy, play a crucial role in reducing greenhouse gas emissions. This study examines the ecological impact in the form of avoided emissions for five geothermal heating plants located in Poland. The analysis included emissions of CO2, SO2, NOx, CO, benzo(a)pyrene, and particulate matter (PM10 and PM2.5), considering three reference scenarios based on conventional fuels: hard coal, high-methane natural gas, and heating oil. The calculations were based on emission factors for fossil fuels and annual geothermal heat production values. The results demonstrated that geothermal heating plants significantly reduce carbon dioxide emissions, one of the key greenhouse gases. Additionally, a substantial reduction in other pollutants was observed, confirming the positive impact of geothermal technologies on both the environment and public health. The findings indicate that geothermal energy is an effective tool in combating climate change, while simultaneously contributing to air quality improvement and supporting sustainable development.

In this study, a phenomenological model, that predicts the particulate matter emission (PM) of diesel engines, has been formulated. The CO-PM model is based on the formation mechanisms of PM and carbon monoxide (CO) of diesel engines. It can predict the emission concentration of PM via the emission concentration of CO. The calculation method of the model is simple and quick. To validate the model, experiments were carried out in two research diesel engines. Comparisons of the model results with the experimental data show good agreement. The model is useful for computer simulations of electronically controlled diesel engines, as well as electronic control unit (ECU) designs for diesel engines.

The present work investigates the effect of natural gas fuel sulfur on particulate emissions from stationary gas turbine engines used for electricity generation. Fuel sulfur from standard line gas was scrubbed using a system of fluidized reactor beds containing a specially designed activated carbon purposely built for sulfur absorption. A sulfur injection system using sonic orifices was designed and constructed to inject methyl mercaptan into the scrubbed gas stream at varying concentrations. Using these systems, particulate emissions created by various fuel sulfur levels between 0 and 15 ppmv were investigated. Particulate samples were collected from a Capstone C65 microturbine generator system using a Horiba MDLT-1302TA micro dilution tunnel and analyzed using a Horiba MEXA-1370PM particulate analyzer. In addition, ambient air samples were collected to determine incoming particulate levels in the combustion air. The Capstone C65 engine air filter was also tested for particulate removal efficiency by sampling downstream of the filter. To further differentiate the particulate entering the engine in the combustion air from particulate being emitted from the exhaust stack, two high efficiency HEPA filters were installed to eliminate a large portion of incoming particulate. Variable fuel sulfur testing showed that there was a strong correlation between total particulate emission factor and fuel sulfur concentration. Using eleven variable sulfur tests, it was determined that an increase of 1 ppmv fuel sulfur will produce an increase of approximately 2.8 μg/m3 total particulate. Also, the correlation predicted that, for this particular engine, the total particulate emission factor for zero fuel sulfur was approximately 19.1 μg/m3. With the EC and OC data removed, the correlation became 2.5 μg/m3 of sulfur particulate produced for each ppmv of fuel sulfur. The correlation also predicted that with no fuel sulfur present, 7.8 μg/m3 of particulate will be produced by sulfur passing through the engine air filter.

Lower blends of biodiesel demonstrated lower emissions, while easing pressure on scarce petroleum resources, without significantly sacrificing engine power output and fuel economy. However due to adverse health effects of smaller size particulate matter (PM) emitted by internal combustion (IC) engines, most recent emission legislations restrict the PM mass emissions in addition to total particle numbers emitted. It is an overwhelming argument that usage of biodiesel leads to reduction in PM mass emissions. In this paper, experimental results of PM emissions using Karanja biodiesel blends (KB20 and KB40) in a modern CRDI transportation engine (maximum fuel injection pressure of 1600 bar) have been reported. This study also explores comparative effect of varying engine speed and load on PM emissions for biodiesel blends vis-à-vis baseline mineral diesel. Particulate size-number distribution, particle size-surface area distribution and total particulate number concentrations were experimentally determined under varying engine operating conditions and compared with baseline mineral diesel. KB20 showed highest particulate number concentration upto 80% rated engine loads, however at rated load, KB40 emitted highest number of particulates.

Reduction of particulate matter (PM) is important issues even for shipping industry since PM harms the environment and human health. In order to reduce PM from marine diesel engines, we focused on components forming PM, elemental carbon (EC), organic carbon (OC), sulfate, and “others” (nitrate, bound water associated with sulfate, metal, ash and hydrogen associated with OC), and investigated the reduction effect of each component by changing fuel injection pressure of a four-stroke marine diesel engine at the two engine load points of 25% and 50%. At 50% load, the PM emissions decreased with increasing the fuel injection pressure, the reduction in the PM emissions which reflected the decrease in EC. At 25% load, the PM emissions did not decrease simply with the injection pressure since OC, sulfate, “others” components in addition to EC contributed to the injection pressure dependence of PM. The results suggest that behaviors of each component of PM should be grasped to achieve the appropriate reduction method of PM.

Full textAbstract:
The present paper describes particulate-matter (PM) emissions from a model gas turbine combustor at atmospheric pressure, focusing on the effects fuel-nozzle configurations have on PM emissions. In this experiment, three types of fuel nozzles were employed: standard, annular, and multi-type. The annular and multi-type were designed as low-PM-emission fuel nozzles, based on our preliminary experimental results using the standard nozzle. Gas oil and fuel oil containing 0.2 wt% of carbon residue were used as the test fuels. The PM concentrations and particle-size distributions were measured with an electrical low-pressure impactor. The experimental results revealed that the PM concentrations for the annular and multi-type were dramatically reduced compared with that for the standard nozzle, demonstrating their PM-reducing effect. We found that the high-concentration regions seemed to be formed by soot aggregation, from the spatial-profile measurements of PM emissions from gas oil combustion. The high-concentration regions for the low-PM-emission fuel nozzles were located further upstream and they were on a smaller scale than that for the standard nozzle. This suggests that their PM-reducing effect may be due to their upstream location and the smaller-scale of their high-concentration regions.

Full textAbstract:
This paper describes the development, testing, and application of a low emissions upgrade kit for 1.5 MW EMD GP20D locomotives. Low emissions development focused on changes to fuel injection timing combined with the application of crank case ventilation system (CCV) and catalyzed diesel particulate filters (DPF). Composed of a porous cordierite ceramic material, the diesel particulate filters are specifically designed for entrapment of diesel particulates while allowing exhaust gases to flow through. Furthermore, the filters are coated with a proprietary catalyzed washcoat that promotes the oxidation of soot within the exhaust gas temperature range observed under normal engine operation. In addition to the low temperature oxidation of soot, the catalyzed filter also reduces carbon monoxide and unburned hydrocarbons. The test locomotive used for this development, which is owned by CIT Rail, was powered by a recently rebuilt Caterpillar 3516B engine with a rated power of 1.5 MW (2,000 HP). Baseline exhaust emission testing was performed, followed by low emissions retrofit development. In combination with the CCV and new fuel injection calibrations, the DPF system netted significant emissions reductions. The result of the final low emissions upgrade kit was an EPA Tier 1+ certification, with emissions levels that were below EPA Tier 3 locomotive switch cycle standards for oxides of nitrogen (NOx) and below EPA Tier 4 switch cycle standards for hydrocarbons (HC), carbon monoxide (CO), particulate matter (PM), and smoke.

Full textAbstract:
An experimental investigation was performed on the effect of engine speed and EGR (exhaust gas recirculation) on the particle size distribution and exhaust gas emissions in a compression ignition engine fueled with biodiesel derived from soybean. The results obtained by biodiesel fuel were compared to those obtained by petroleum diesel fuel with sulfur contents of 16.3 ppm. The scanning mobility particle sizer (SMPS) was used for size distribution analysis and it measured mobility equivalent particle diameter in the range of 10.4 to 392.4 nm. In addition to the size distribution of the particles, exhaust emissions such as oxides of nitrogen (NOx), hydrocarbon (HC), and carbon monoxide (CO) emissions and combustion characteristics under different engine operating parameters were investigated. The engine operating parameters in terms of engine speed, EGR, injection pressure, and intake pressure were varied to investigate the individual impact of the operating parameters. As the engine speed was increased for the both fuels, the larger size particles which dominantly contributes particle mass was increased, however total numbers of particle were reduced. Comparing to petroleum diesel fuel, the combustion of biodiesel fuel in the engine reduced particle concentration of relatively larger size where most of the particle mass is found. Moreover, dramatically lower hydrocarbon and carbon monoxide emissions were found at the biodiesel fueled engine. However, the NOx emission of biodiesel fueled diesel engine shows slightly higher concentration compared to diesel fuel at the same injection timing.

<div class="section abstract"><div class="htmlview paragraph">Vehicle emissions, which are rising alarmingly quickly, are a significant contributor to the air pollution that results. Incomplete combustion, which results in the release of chemicals including carbon monoxide, hydrocarbons, and particulate matter, is the main cause of pollutants from vehicle emissions. However, CO<sub>2</sub> contributes more than the aforementioned pollutants combined. Carbon dioxide is the main greenhouse gas that vehicles emit. For every liter of gasoline burned by vehicles, around 2,347 grams of carbon dioxide are released. Therefore, it’s important to reduce vehicle emissions of carbon dioxide. The ability of materials like zeolite and silicon dioxide to absorb CO<sub>2</sub> is outstanding. These substances transform CO<sub>2</sub> into their own non-polluting carbonate molecules. Zeolite, silicon dioxide, and calcium oxide are combined to form the scrubbing material in a ratio based on their increasing adsorption propensities, along with enough bentonite sand to bind the mixture.</div></div>

Abstract Aviation is known to be one of the most significant contributors to air pollutants. This includes gaseous emissions, like carbon-dioxide (CO2) and nitrogen oxides (NOx), and also particulate matter (PM), especially in the form of soot. This study conducted emission measurements on an Allison 250-C20B turboshaft engine operating on Jet A-1 fuel with a focus on gaseous compounds (e.g. ozone precursors) and PM, regarding their number and mass concentration. The different engine loading points were chosen based on the percentage thrust ratios of the International Civil Aviation Organization (ICAO) Landing and Take-Off-Cycle (LTO-Cycle). A standard FTIR/O2/FID system to measure general combustion compounds e.g. CO2, carbon-monoxide (CO), unburned hydrocarbons (UHC), and NOx, was used for the gaseous measurements. For the investigation of the volatile organic compounds (VOC), which are known to act as ozone precursors, a gas-chromatograph (GC) was applied. Different measurement methods were used to characterize the PM emissions. For the particle size distribution (PSD), we used two types of electrical mobility analyzers (SMPS and DMS500) and an aerodynamic aerosol classifier (AAC). All measurement systems yielded comparable PSD results, indicating reliable results. The particle measurement methods all show increasing aerosol diameter modes (electrical and aerodynamic) with increased engine loading. The aerosol diameter modes were shifting from 29 nm to 65 nm. Furthermore, the size and shape of different individual particles were evaluated with a scanning electron microscope (SEM). In addition, a correlation between the injection system and the particle formation was established. Gaseous turboshaft engine emissions show high CO and UHC values in Ground Idle (GI) level. NOx levels were the highest at Take-Off (TO) conditions. Acetylene and ethylene were the most significant contributors to ozone formation.

Full textAbstract:
The purpose of this note is to document data sources and steps used to develop the air pollution database for the GTAP Data Base Version 10A. Emissions for nine substances are reported in the database: black carbon (BC), carbon monoxide (CO), ammonia (NH3), non-methane volatile organic compounds (NMVOC), nitrogen oxides (NOx), organic carbon (OC), particulate matter 10 (PM10), particulate matter 2.5 (PM2.5) and sulfur dioxide (SO2). The dataset covers four reference years – 2004, 2007, 2011 and 2014. EDGAR Version 5.0 database is used as the main data source. To assist with emissions redistribution across consumption-based sources, IIASA GAINS-based model and IPCC-derived emission factors are applied. Each emission flow is associated with one of the four sets of emission drivers: output by industries, endowment by industries, input use by industries and household consumption. In addition, emissions from land use activities (biomass burning) are estimated by land cover types. These emissions are reported separately without association with emission drivers.

Full textAbstract:
Local air pollutants (LAPs), such as carbon monoxide, hydrocarbon, sulfur oxide, nitrogen oxide, ozone, and particulate matter, as well as greenhouse gas (GHG) emissions from the transport sector are rapidly increasing in the People’s Republic of China. Various measures to control LAPs have been implemented in the country, along with the adoption of strategies to mitigate GHG emissions. The connection between LAP and GHG emission control and reduction offers an opportunity to address both problems simultaneously. This paper presents a methodology that measures the benefits of co-control evaluation on mitigating LAP and GHG emissions. It highlights the methodology’s potential to help maximize measures and strategies that have significant co-control effects.

Full textAbstract:
Black carbon – also referred to as soot – is a particulate matter that results from the incomplete combustion of fossil fuels and biomass. As a major air and climate pollutant, black carbon (BC) emissions have widespread adverse effects on human health and climate change. Globally, exposure to unhealthy levels of particulate matter, including BC, is estimated to cause between three and six million excess deaths every year. These health impacts – and the related economic losses – are felt disproportionately by those living in low- and middle-income countries. Furthermore, BC is a potent greenhouse gas with a short-term global warming potential well beyond carbon dioxide and methane. Worse still, it is often deposited on sea ice and glaciers, reducing reflectivity and accelerating melting, particularly in the Arctic and Himalayas. Therefore, reducing BC emissions results in a triple win, mitigating climate change, improving the lives of more than two billion people currently exposed to unclean air, and saving trillions of dollars in economic losses. Today, the majority of BC emissions stem from just a handful of sectors and countries. Over 70% of BC comes from the residential and transportation sectors, with the latter being the dominant source in high-income countries and the former driving emissions in low- and middle-income nations. On a country-level, China and India are the biggest emitters accounting for one-third of global BC emissions. When combined with Brazil, Indonesia, and Nigeria, these five countries alone emit 50% of all BC. While BC emissions trends over the past 20 years have been inconsistent globally, there has been a notable decline in Europe, North America, and China. Conversely, emissions have been rising in regions like Africa, South Asia, and Central Asia. The Intergovernmental Panel on Climate Change recommends deep reductions in BC emissions by 2030 to achieve the Paris Climate Agreement goal of limiting warming to below 1.5°C, yet very few countries have addressed BC in their climate plans. Fortunately, solutions that can rapidly reduce BC emissions by the end of this decade are readily available. By implementing the right policies, deploying targeted interventions in hotspots, and redirecting climate finance, policymakers and funders can mitigate the climate effects of BC while saving millions of lives and trillions of dollars. Below are key recommendations to achieve these aims based on the findings of this report: Urgently implement clean cooking solutions Providing clean cooking fuels and technologies in sub-Saharan Africa and South Asia, especially in the hotspots of the Indo-Gangetic Plains, Nigeria, and Uganda, can significantly reduce BC emissions. Countries with low penetration of clean cooking fuel must urgently develop policies that make clean cooking a priority for health and climate. Target transportation to reduce current – and prevent future – emissions Retrofitting older diesel engines with diesel particulate filters can remove up to 95% of BC. Countries around the world must implement policies to phase out polluting vehicles, set emission standards, and accelerate the uptake of EVs and hybrids, especially in urban regions where transportation demand is growing rapidly. A successful shift to EVs demands national investments complemented with international financing and private capital. Multilateral development banks need to play a pivotal role in this transition, with strategies like concessional finance to fast-track key projects and stimulate private sector investment. Reduce BC from the shipping industry BC emissions from the shipping industry must be urgently reduced to protect the Arctic ecosystem. Shifting shipping away from heavy fuel oil and equipping ships with diesel particulate filters is a cost-effective approach that would quickly and significantly reduce emissions. Regulate air quality Stringent emissions standards, clean air laws, baselines, and mandatory monitoring programs can effectively reduce BC emissions. Such policies have already resulted in large reductions in Europe, North America, and, more recently, China. However, several low- and middle-income countries have no legal protection for ambient air quality and lack legislatively-mandated standards. Implementing strong and legally binding policies can result in a large decrease in BC emissions, particularly across the transportation and industry sectors. Include BC in nationally determined contributions and the UNFCCC Only 12 countries have explicitly addressed BC in their nationally determined contributions (NDCs). This limited focus on BC is partly due to its omission from the United Nations Framework Convention on Climate Change’s (UNFCCC) list of climate pollutants, an oversight that should be reconsidered given that reducing BC would save countless lives and slow global warming. As nations review their NDCs by 2025, they must incorporate BC reduction efforts to meet climate and well-being targets. Improve BC measurements and estimates BC estimates are plagued by uncertainties. Therefore, there is an urgent need for more accurate inventories in order to develop better emission reduction plans. Stakeholders must collaborate to develop a consistent BC measurement protocol, prioritize the collection of high-quality data, and use state of the art models to enhance estimates and reduce uncertainties.

Full textAbstract:
This paper investigates how and why firms affected by Emissions Trading Schemes (ETSs) are financially accounting for carbon in a voluntary setting. Using institutional theory, the authors seek to identify the determinants of a firm’s decision to adopt a particular carbon financial accounting practice. We identify the recognition and measurement practices for carbon-emission allowances using data gathered from the annual reports of ETS-affected firms in Australia. These practices are identified in the five stages of carbon-emission allowance transactions, namely, when these are: (1) received for free, (2) purchased, (3) used, (4) sold, and (5) surrendered. Inconsistencies in carbon financial accounting practices are observed. The findings reveal that carbon-emission allowances are recorded as intangible assets, but most firms provide incomplete information on their carbon financial accounting practices. Firms also exhibit inconsistencies in specifying how they are ‘recognising’ and ‘measuring’ carbon-emission allowances. The results provide evidence of coercive (regulation) and mimetic (size, leverage, and listing status) pressures being the main determinants of carbon financial accounting practice.

This rapid literature review summarises evidence on Emission reductions and health impacts of Low and Zero Emission Vehicles (LEVs and ZEVs). The review found a disparate but emerging evidence base derived from studies exploring the issue in a range of settings (predominantly high and middle income countries). The evidence base provides a mixed and complex picture given the heterogeneity of methodological approaches and contextual analyses to assessing reductions and health impacts. The report found a focus on carbon emission reduction and less evidence on other emissions. Given the above, evidence has been collected and presented in an annotated bibliography. A note of caution should be raised when drawing lessons from particular studies, with findings influenced by a range of contextual factors.

Full textAbstract:
This paper estimates effective carbon rates (ECRs) on carbon dioxide (CO2) emissions from energy use for 18 Latin American and Caribbean (LAC) countries. We follow a methodology developed by the Organization for Economic Co-operation and Development (OECD) as this allows us to compare ECR estimates for LAC countries with those for other countries in other regions. We also adapt the OECD methodology to assess the effect of energy subsidies on ECRs. The results obtained indicate that ECRs were low in LAC countries in 2018. On average, LAC countries priced carbon emissions from energy use at 24 euros per ton of CO2 equivalent (EUR/tCO2e) emissions, while the average pricing in OECD countries was 41 EUR/tCO2e. When considering energy subsidies, the average ECR in LAC falls to 17 EUR/tCO2e. The difference in average carbon pricing observed between LAC and the OECD is, for the most part, explained by lower excise taxes in LAC and, to a lesser extent, to few LAC countries having carbon taxes and the lack of tradable carbon emission permit mechanisms. We also find a large heterogeneity of ECRs across LAC countries as well as across sectors within countries. ECRs are the highest in Costa Rica and the lowest in Ecuador. At the sector level, ECRs are on average the highest in the road transport sector and the lowest in the electricity sector and in the residential and commercial energy use sector. These differences stem mostly from the different taxation of the different energy products. The ECR estimates suggest that countries willing to introduce carbon pricing reforms must pay particular attention to reducing fuel energy subsidies and to increasing ECRs in sectors other than road transport, as these sectors constitute a large share of carbon emissions and are virtually untaxed.

Full textAbstract:
Net-zero climate policies foresee deployment of atmospheric carbon dioxide removal wit geological, terrestrial, or marine carbon storage. While terrestrial and geological storage would be governed under the framework of national property rights, marine storage implies that carbon is transferred from one global common, the atmosphere, to another global common, the ocean, in particular if storage exceeds beyond coastal applications. This paper investigates the option of carbon dioxide removal (CDR) and storage in different (marine) reservoir types in an analytic climate-economy model, and derives implications for optimal mitigation efforts and CDR deployment. We show that the introduction of CDR lowers net energy input and net emissions over the entire time path. Furthermore, CDR affects the Social Cost of Carbon (SCC) via changes in total economic output but leaves the analytic structure of the SCC unchanged. In the first years after CDR becomes available the SCC is lower and in later years it is higher compared to a standard climate-economy model. Carbon dioxide emissions are first higher and then lower relative to a world without CDR. The paper provides the basis for the analysis of decentralized and potentially non-cooperative CDR policies.
