Reducing carbon footprint is a trend within modern green restaurants. A carbon footprint is the total set of greenhouse gas (GHG) emissions caused by an organization, event or product. Food and beverage restaurants have to deliver food using a minimal carbon footprint. Of previous researches, only a small fraction is focused on reducing carbon footprints in a culinary room. Besides, a carbon footprint cost model was hard to solve in economic computation time. Therefore, the main purpose of this research is through a distributed information system to accelerate computing ability of a carbon footprint cost model. Through the distributed computing, our experimental results showed that the proposed approach outperformed the literature approach efficiently. The algorithm improved rate was 68.6%, and low down 82.1% carbon footprint than manual. The proposed approach could contribute to accelerate calculations in others problems due to using multiple machines in future researches.

The National Tourism Conference in 2010 strongly promoted the concept of energy conservation and emission reduction in the tourism industry. Since then, low carbon travel has been the new direction in tourism industry. Great concern has been put on energy conservation and emission reduction of tourism related elements, such as hotels, transportations, tourist attractions, and most importantly, the tourists themselves. The quantitative assessment of tourist carbon footprint is the key topic. This research uses Yesanpo scenic area as the example and conducts the comparison and calculation of tourist carbon footprint from different places, attempts to organize different ideas on ways to analyze tourist carbon footprints, constructs a calculation and assessment model, analyzes and measures the levels of tourist carbon footprints from diverse modes of travel, origins, and purchasing power. This research has developed a system for quantitative assessment of tourist carbon footprints, with the hope of strengthening the theories and methods on low-carbon travel.

Using an imported timber-based solid wood box bed (2000 mm × 1800 mm) as the functional unit, the ILCD 2011 midpoint assessment method was used to measure the life cycle carbon emissions of the product. Using this assessment, the Dijkstra algorithm was adopted to determine the shortest supply chain path and to obtain the minimum carbon footprint of the supply chain. Results showed that the total carbon footprint of the wood bed was 464 kg for the control case. For experimental cases, the carbon footprint ranged from 456 kg to 517 kg CO2-eq. The upstream process was identified as the primary contributor to the carbon footprint, accounting for 74.6% to 80.7% of the total carbon footprint, followed by the downstream and the core-stream processes. Configuration of a timber harvesting system with lower fuel consumption, purchasing timber from areas within shorter transportation distance, and reducing the proportion of incineration for waste treatment were feasible solutions to reduce the carbon footprint of the product. A case study optimizing the low-carbon path for the wooden furniture supply chain determined the shortest path for the participants in each link, such that the minimum total carbon footprint of the supply chain was 463 kg CO2-eq.

Based on the data of provincial input-output model and the carbon footprint model, the analysis is focused on provincial carbon footprint and the space transfer of carbon emissions. The results have shown that: (1) There are significant differences of provincial total carbon footprint amounts: resource-rich provinces have high total carbon footprint amounts, followed by processing and manufacturing provinces and municipalities; Regions with high energy efficiency have low carbon footprint amounts, so does southwestern region where economic and industrial development level is relatively low. (2) The provincial differences of carbon footprint per capita are related to demand structure: the amounts of carbon footprint are high in provinces with higher demand of consumption and investment, especially those provinces with strong demand for construction and processing industries. The amounts of carbon footprint are low in provinces which are non-resource-based, have limited investment and construction, and its economic structure is not dominated by processing and manufacturing. (3) Interprovincial trades have a significant impact on carbon footprint and carbon emissions. Provinces with well developed infrastructure have net CO2 emissions flow-in that are directly induced by high energy consumption products; southwestern region, where processing and manufacturing industry is relatively less-developed, has main CO2 emission flow-in, which are induced by the demand of processing and manufacturing industries; resource-intensive provinces and provinces with well-developed processing and manufacturing industries have net CO2 emission flow-out, which are induced by interprovincial trades.

The investigators have tried to know the awareness and practices of Postgraduate students studying in various streams of education at the University of Balasore, Odisha, India in reducing carbon footprint. In this study investigators used the stratified random sampling method to select the sample consisted of 180 students, comprising both female and male students. In the study data was collected by using Carbon footprint awareness test and Carbon footprint practices scale constructed by the investigators themselves. The findings revealed that more than half of the students had low level of carbon footprint awareness; whereas no significant difference was found between female and male students in their level of carbon footprint awareness; however students who followed different academic courses had varying degrees of awareness of their carbon footprint. The findings also revealed that half of the students had low level of carbon footprint practices and there exists a statistically significant difference in the mean carbon footprint practice scores of postgraduate students from different streams of education. There is a correlation between carbon footprint awareness and carbon footprint practices as viewed by the postgraduate students. Thus, it can be inferred that as the awareness of carbon footprint increases among postgraduate students, their implementation of practices to reduce carbon footprint also increases.

Abstract The paper aims to study the importance of low-carbon landscape design based on rural tourism landscape. First of all, after sorting out and researching the relevant reviews of low-carbon landscapes, taking rural landscapes as the research object, a rural landscape planning and design framework based on the perspective of low-carbon construction is proposed. Then, Xiwuli Village is used as an example to carry out the application practice of specific strategies and the carbon emissions before and after the planning and design are calculated and compared. After the low-carbon planning and design of the rural landscape, the net carbon footprint and the total carbon footprint were significantly reduced, confirming the low-carbon effect of the planning and design strategy. Finally, according to the actual situation of the scenic spot, it points out the principles and policy suggestions that must be followed in the development of low-carbon rural tourism. Experiments show that: the net carbon footprint and total carbon footprint are significantly reduced, which proves the actual effect of low-carbon design and the effect of low-carbon planning and design strategy.

The carbon footprint of motorized transport modes per unit length traveled encompasses the unit share of the vehicle lifetime emissions, that of the transport infrastructure, and those of the motor energy, considered both from “well to tank” and from “tank to wheel”. In the active modes of transport, i.e., walking and cycling, the counterpart of motor energy is human energy, which is associated with two kinds of carbon flows: the carbon footprint of food intake, – which we call the Food to Body component – and the carbon dioxide emissions of respiration – say the Body to Foot component. In this article, we provide a model in simple mathematical form to assess those carbon flows per unit length. It involves the modal speed in (i) the Metabolic Equivalent of the Task (MET) which gives rise to the energy and carbon flows, and (ii) the ratio of time spent to length travelled. The two influences of speed onto a modal carbon footprint combine in the net MET per unit length, with some compensation. The carbon footprint of food intake varies widely depending on the food diet of individuals. In a numerical study, the Food to Foot carbon emission of walking, cycling, e-scooter riding, and driving a car are estimated and compared to the rest of modal carbon footprint. Under conditions typical of France in the 2010s based on the average food diet and low carbon intensity of electricity, the inclusion of F2F in modal footprints changes the ranking of the modes according to the carbon footprint per unit length.

Low-carbon tourism is an important way for the tourism industry to achieve the United Nations Sustainable Development Goals and the goals of carbon peaking and carbon neutrality. In order to promote the development of Guilin as a world-class tourism city and ensure the sustainable development of the tourism industry in Guilin, this paper combines the concept of carbon footprint and the theory of life cycle to build a tourists’ carbon footprint life cycle analysis model of Guilin. Taking tourists in Guilin as an example, the composition and changes of tourists’ carbon footprint are dynamically analyzed. The research shows that: (1) The overall tourism carbon footprint of Guilin showed an upward trend during 2011–2019. From 2020 to 2022, due to the impact of COVID-19, Guilin’s tourism carbon footprint has decreased significantly. The per capita carbon footprint of tourism in Guilin showed a downward trend from 2011 to 2022; (2) The order of the size of Guilin’s tourism carbon footprint is tourism transportation > tourism catering > tourism accommodation > tourism activities; (3) From 2011 to 2022, the carbon footprint of tourism transportation in Guilin showed an obvious narrowing state, while the carbon footprint of tourism accommodation, tourism activities, and tourism catering showed an obvious expanding trend. Based on the characteristics of the carbon footprint of Guilin’s tourism and the current situation of the development of Guilin’s tourism, this paper puts forward suggestions on reducing carbon emissions, forms a new tool for evaluating and constructing low-carbon tourism, and provides a scientific basis and practical reference significance for the sustainable development of low-carbon tourism in Guilin.

In advocating the principle of sustainable development, urban development calls for reducing the carbon dioxide emissions to promote low carbon economy. Low-carbon design is the foundation and effective method of low-carbon economy development. By analyzing the principles of low-carbon urban development, methods of low-carbon design were discussed so as to guide people's low carbon consumption and reduce carbon footprint. Low-carbon design process was proposed at last. In this way, the development of low-carbon urban could be carried out by starting from the source.

Energy consumption and emissions are the two main sustainability issues of German companies. The main reasons for efficiency increase and emission reduction are not, as often proclaimed, energy costs, but the demands of customers and legislators for low carbon emissions. Particularly at machine level and process chain level various methods for analysis and improvement of the energy efficiency already exist. At factory level there is no systematic approach. The method Factory Carbon Footprint Design is an appropriate tool for that issue. The method is derived from the activity-based costing method and has two main parts: The Activity-based Carbon Footprint Accounting and the Target Carbon Footprint Design. Using the Activity-based Carbon Footprint Accounting, the carbon footprint of all energy consumers can be allocated to the goods produced in the factory. This contains not only the carbon footprint of the manufacturing machines, but also the periphal equipment and the administration and other indirect parts of the factory. The Target Carbon Footprint Design is a systematic approach to reduce the overall carbon footprint of a factory.

It is a matter of apprehension that wealthy countries are contributing huge to global emission and more responsible for producing greenhouse gases in the atmosphere. There is direct intervention of economic activities like industrialization, urbanization and infrastructure development over carbon footprint across the world and economically developed nations tend to have higher footprints as compared to less developed countries. India, the second largest populous nation is facing dual challenges, one hand, the need to fulfill the energy requirement for development and on the other hand, the global climate challenge. The country is third largest emitter of CO2 and fifth largest economy by nominal GDP in the world. But its per capita emission is much lower than that of developed countries and even it is below the average per capita emission of many developing countries. The present paper is an attempt to map the carbon footprints across the country in respect to the economic status. The paper reveals that there exist huge disparities of economic resources and developmental activities, and based on these the carbon footprint is also varied widely. The footprint is significantly high in developed and urbanized states across the country. Economically developed western and southern part emits more than the underdeveloped region of Bihar, Uttar Pradesh, Jharkhand and Odisha. A correlation has been drawn to map the carbon footprint per capita in respect to poverty ratio and a negative relationship exists among most of the districts, as higher carbon footprint has been reported in the lower poverty stricken districts. The overall low per-capita carbon footprint of the country is due to its huge population is living with nominal amount of energy. The fossil fuel is the major source of energy in the country and for equitable economic development, the huge energy is needed. Hence, to meet the global climate challenge, the country can accomplish the energy requirement by reducing emission of conventional sources and look forward for renewable energy resources, so that the development should not be hindered.

As a larger use of agricultural machinery, the measurement of carbon emission is highly important. Quantification of the carbon footprint is important for the identification of more sustainable and environmentally friendly practices. Information about input energy (fuel energy) used by some tillage techniques was collected and converted into carbon. In order to use low emission tillage operations, the equivalent carbon emission factors of each tillage technique were determined. The carbon equivalents for using traditional tillage system were the highest comparing with other tillage systems (158.63 kg CE ha-1 and 55.63 kg CO2e ha-1), while No-till system which give (5.8 kg CE ha-1 and 5.45 kg CO2e ha-1). Improved conservation technology and management equipment can all help minimize the carbon footprints of farm machinery.

Abstract Background The aim of this study was to estimate the carbon footprint and financial cost of decontaminating (steam sterilization) and packaging reusable surgical instruments, indicating how that burden might be reduced, enabling surgeons to drive action towards net-zero-carbon surgery. Methods Carbon footprints were estimated using activity data and prospective machine-loading audit data at a typical UK in-hospital sterilization unit, with instruments wrapped individually in flexible pouches, or prepared as sets housed in single-use tray wraps or reusable rigid containers. Modelling was used to determine the impact of alternative machine loading, opening instruments during the operation, streamlining sets, use of alternative energy sources for decontamination, and alternative waste streams. Results The carbon footprint of decontaminating and packaging instruments was lowest when instruments were part of sets (66–77 g CO2e per instrument), with a two- to three-fold increase when instruments were wrapped individually (189 g CO2e per instrument). Where 10 or fewer instruments were required for the operation, obtaining individually wrapped items was preferable to opening another set. The carbon footprint was determined significantly by machine loading and the number of instruments per machine slot. Carbon and financial costs increased with streamlining sets. High-temperature incineration of waste increased the carbon footprint of single-use packaging by 33–55 per cent, whereas recycling reduced this by 6–10 per cent. The absolute carbon footprint was dependent on the energy source used, but this did not alter the optimal processes to minimize that footprint. Conclusion Carbon and financial savings can be made by preparing instruments as part of sets, integrating individually wrapped instruments into sets rather than streamlining them, efficient machine loading, and using low-carbon energy sources alongside recycling.

Carbon footprint is emerging as an effective tool for carbon emission management, especially that from fossil energy consumption. In addition, decoupling analysis is important to keep a high pace of economic growth while reducing carbon emission and its carbon footprint. Taking the Yangtze River Delta (YRD) urban agglomeration in China as a case, this paper examined the changes in carbon footprint and carbon footprint pressure by incorporating land resource limits. On this basis, we further analyzed the decoupling relationships between carbon footprint, carbon footprint pressure and economic growth. The GeoDetector was also employed to detect the spatial heterogeneity of the carbon footprint pressure. The results showed that despite the decrease of carbon emissions from 2011 to 2019 in the YRD, carbon footprint pressure still revealed an increased trend in this period. As to the decoupling relationships between carbon footprint, carbon footprint pressure and economic growth, they were improved in most of the cities in the YRD, changing from expansive coupling to weak decoupling to strong decoupling. However, the descending trend of decoupling elasticity coefficient for carbon footprint pressure is smaller than that of the carbon footprint. This result could be explained by the fact that not only carbon emission but also carbon sequestration (by productive lands including forests and grasslands) pose large impacts on carbon footprint pressure. The findings indicate the necessity not only to reduce carbon emission, but also to protect productive lands to realize low carbon economy.

Popular modern diets are often seen as a panacea for improving health and promoting weight reduction. While there is a large body of literature reporting the health benefits of popular diets, few studies have described their planetary benefits. Our investigation aims to evaluate the simultaneous impacts of six popular diets within the United States on both human and planetary health. Using carbon footprint databases and representative meal plans, the environmental and health-related impacts of the Standard American, Mediterranean, vegan, paleo, keto, and climatarian diets are compared using the currently available literature. Results indicate that diets that exhibit lower carbon footprints also have positive effects on human health. The diets found to have the lowest environmental impacts were the vegan, climatarian, and Mediterranean diets. These low-carbon-footprint diets can likely be attributed to a reduced reliance on ruminant meat (cattle and sheep) and processed food consumption, while diets with high carbon footprints are more dependent on ruminant meat and saturated fat. Moderate consumption of meats such as chicken, pork, and fish in conjunction with an emphasis on locally grown fruits and vegetables can be maintained without adversely affecting the planetary carbon footprint and with the added benefit of promoting good health. Thus, making simple substitutions within each individual’s diet can be advertised as an effective approach to collectively lower the environmental impact in tandem with improving health and longevity.

Carbon footprint has become a reference indicator of the environmental impact of food production. Governments are increasingly demanding a trend towards low-carbon-footprint production in order to reduce the impact on climate change. In this sense, the study of consumers’ preferences and assessment of products from the perspective of their carbon footprint is crucial to achieve a green and circular economy. This paper specifically attempted to assess consumer preference and willingness to pay for beef that has been carbon-footprint-labelled as an attribute. In order to attain this objective, a choice experiment was designed and applied to a total of 362 Spanish consumers. The results revealed a positive preference towards beef produced in low-carbon-footprint systems. In addition, the segmentation of these consumers revealed the existence of a group of consumers who prioritise environmental impact over product price.

To achieve the goal of carbon neutrality, many countries have established regional carbon emission trading markets and tried to build a low-carbon economic system. At present, the implementation of carbon emission trading and low-carbon economic systems faces many challenges such as manipulation, corruption, opacity, lack of trust, and lack of data tracking means. The application of blockchain technology can perfectly solve the above problems. However, the data recorded on a blockchain are often multi-type and heterogeneous, and users at different levels such as regulators, enterprises, and consumers have different requirements for data types and granularity. This requires a quick and trustworthy method for monitoring the carbon footprint of enterprises and products. In this paper, the carbon footprint traceability of enterprises and products is taken as an application scenario, and the distributed traceability concept of “traceability off the chain and verification on the chain” is adopted. By reconstructing the pointer of the file structure of the distributed storage, an interactive traceability structure supporting type filtering is constructed, which enables fast retrieval and locating of carbon emission data in the mixed data on the chain. The experimental results show that using the interactive traceability structure that supports type filtering for traceability not only releases the computing power of full nodes but also greatly improves the traceability efficiency of the long-span transaction chain. The proposed carbon footprint traceability system can rapidly trace and track data on an enterprise’s and a product’s carbon footprint, as well as meet the needs of users at all levels for traceability. It also offers more advantages when handling large amounts of data requests.

This study aims to provide a scientific basis to address the strategies for sustainable development of urban tourism industry. By using the Life Cycle Assessment method, it decomposes tourism activities into seven different functional units (different tourism activities)-transportation, catering, accommodation, sightseeing, shopping, entertainment and waste disposal-based on the expression of services provided by tourism activities, and determine the boundary range of each different functional unit in terms of the pathways and the functional orientation of the products (resources and energy) provided by the services of each functional unit. A “bottom-up” model is then constructed to measure the carbon footprint of tourism. Based on data collected from various sources for the period 2014–2019, it compares the composition and differences of domestic and international tourists’ carbon footprints in Chenzhou City, one of inland mountainous regions of central China, through several steps, including target and scope definition, inventory analysis, impact evaluation and life cycle interpretation. Results show that domestic tourists contributed more than 90% of the total annual carbon footprints to the city, ranging from 76.8809 × 106 kg to 194.6067 × 106 kg. Transportation is the dominant category, accounting for over 80% of the total carbon footprints. The study suggests that optimizing tourism resources, reducing transportation distances, and switching to low-carbon modes can effectively reduce the tourism carbon footprints in Chenzhou and similar regions. This study reveals the structural characteristics of the tourism carbon footprint and its influencing factors and provides valuable insights for policy development involving energy saving and low carbon tourism, thus enhancing the long-term sustainability of tourism development in an urban tourism destination like Chenzhou.

The object of the study is the carbon footprint (CO2), which is skyrocketing despite augmented awareness of this issue and a growing willingness to act. The effects of climate change have recently become more severe and have garnered international attention. Recent discussion has focused on carbon footprint as one of the most urgent global issues facing all nations. The tradeoff between carbon footprint and economic growth for credible climate change measures is still understudied in terms of rigorous economic causal analysis. To comprehend the magnitude and speed of the transition away from an agricultural-based economy, it is necessary to quantify and compare the levels of carbon footprint associated with the agricultural, industrial, and service sectors of the country. In order to understand each economic sector's individual contributions to the overall carbon footprint and to assess the relationship between level of economic diversification and the levels of emissions, first identify the main factors and forces that have an impact on each sector's carbon footprint and then consider how the country's transition away from an agricultural-based economy has affected emissions in other economic sectors. This study investigates the impact of the economy's transition away from cash crops on carbon footprint, analyzes the conversion-affecting variables, and quantifies the significance applying the environmental Kuznets curve (EKC), and then regress the model. It is found that there is an inverted U-shaped pattern in the association between carbon footprint and each of industry, service, and manufacturing value added; agriculture, however, shows insignificant inverted U-shaped pattern. In addition, we discovered that every dependent variable – aside from the GDP contribution of agriculture – has a positive correlation with carbon footprint. Analysis revealed that improving agriculture results in lower carbon dioxide emissions. While the economic contributions of agriculture are more environmentally friendly, those of industry, services, and manufacturing leave carbon footprints behind to achieve sustainability, agricultural policy subsidies and deregulation may function as driving factors for the expansion of the cash crop economy. On the one hand, tax policy may be an effective instrument for boosting low-carbon energy consumption in the sector. It is presumptive that environmental phenomena, such as earthquakes, tsunamis, and flues, have not had a significant impact on the economy. This article is pertinent to the nations now dealing with significant environmental problems.

Purpose Green supply chain management and new product innovation and diffusion have become quite popular and act as a rich source of providing competitive advantage for companies to trade without further deteriorating environmental quality. However, research on low-carbon footprint supply chain configuration for a new product represents a comparably new trend and needs to be explored further. Using relatively simple models, the purpose of this paper is to demonstrate how carbon emissions concerns, such as carbon emission caps and carbon tax scheme, could be integrated into an operational decision, such as product procurement, production, storage and transportation concerning new fast-moving consumer goods (FMCG) product introduction. Design/methodology/approach The situation titled “low-carbon footprint supply chain configuration problems” is mathematically formulated as a multi-objective optimization problem under the dynamic and stochastic phenomenon concerning receiver’s demand requirements and production plant capacity constraints. Further, the effects of demand and capacities’ uncertainties are modeled using the chance constraint approach proposed by Charnes and Cooper (1959, 1963). Findings Various cases have been validated using the case example of a new FMCG product manufacturer. To validate the proposed models, data are generated randomly and solved using optimization software LINGO 10.0. Originality/value The attempt is novel in the context of considering the dynamic and stochastic phenomenon with respect to demand center’s requirements and manufacturing plant’s capacity constraints with regard to the low-carbon footprints supply chain configuration of a new FMCG product.

With the advancing steadily in the work of “carbon peaking and carbon neutrality” target, the quantification of carbon emissions has become a difficult problem for substation management. Power supply companies in various cities have a large amount of low-carbon investment, but cannot explain the effect and output clearly, which is difficult to meet the purpose of implementing "carbon peaking and carbon neutrality" in the power system. To this end, this paper takes the substation as the object, establishes an abstract carbon model, analyzes the carbon expression and quantification method in various activities of the substation in the construction stage, operation stage, and demolition stage, and defines fixed, continuous and comprehensive carbon emissions to describe the carbon footprint. The research results show that reasonable low-carbon investment can effectively promote the neutralization of the substations carbon footprint. By further adopting long-term energy-saving measures for equipment and sufficient new energy installed capacity, the substation can offset the load consumption in the station through new energy power generation, and achieve carbon neutrality state. In addition, combined with the actual low-carbon design of a substation, this paper introduces the latest design route and actual effect of carbon reduction in substations, which provides ideas for the design and construction of low-carbon substations in the future.

Agricultural producing activity is one of the emission sources of greenhouse gases, and carbon footprint is a new concept emerging in the context of developing low-carbon economy. In this paper, the agricultural carbon footprint in Liaoning Province was calculated and analyzed with carbon footprint method. According to the results, carbon cost caused by the application of chemical fertilizer and land irrigation, as well as the application of diesel oil in agricultural machinery takes up a high percentage in the input carbon footprint, and the total carbon footprint increases year by year. The carbon intensity calculated in unit output occurs in a declining trend, while the carbon intensity calculated in unit cultivated area fluctuates constantly in a small range, and the carbon efficiency occurs in evident increasing trend. Finally, deficiencies of the study and problems that should be further discussed were proposed.

Mass production of paper is one of the significant factors that are contributing to increase in carbon outrush in the global ecological system. The paper trade releases large volumes of air, water, and soil pollutants, which pony up to green house gasses. The rotted paper releases methane gas, which is many times more hazardous than carbon dioxide. Paperless business is a vital environmental business practice that is better for the upliftment of the current degrading environment. Global corporations are promoting paperless workplaces to move a step forward towards a sustainable ecological system and achieve the sustainable development goals of the United Nations. The research study after observation opined that although various challenges are being portrayed by employing digitalization of workplaces still working paperless is quite fruitful for the global ecological system. The digital innovations are the only alternatives available in the current times for the paper based job places. In this research study fairly was also studied the critical aspect of paperless workplace. On analyzing the dark data of the global corporeal world it was depicted that digitalization is also enhancing the carbon footprint. It is thus concluded in this research study that sensible and secure use of digital technology could only make paperless working successful.

The aging population has posed a challenge to China’s carbon neutrality pledge. To study the household carbon footprint in an aging society, this paper has combined the age-specific consumption pattern and environmental input-output life cycle assessment (EIO-LCA) to calculate the carbon footprint of household consumption across age groups, and then identified the key pathways of carbon emissions via structural path analysis (SPA). Results indicate that the elderly contribute 11.65% to total consumption-based carbon emissions. The working group (ages 15–64) has the highest average carbon footprint (0.85 tCO2e), while the elderly group (ages 65 and above) has the lowest average carbon footprint (0.82 tCO2e). Urban households of all ages have a higher carbon footprint than rural households. Housing and food are the dominant sources of the elderly carbon footprint. Notably, the production and distribution of electric power and heat power sector associated with housing energy consumption plays a leading role in the carbon emissions pathways of elderly consumption. Measuring the carbon footprint of older people can support policy designs and decision making in key sectors along the supply chain, and further encourage low-carbon lifestyles among China’s elderly. Additionally, the findings of this study have broad applications, especially for developing countries undergoing demographic transitions.

Low-carbon production is one of the dominating issues in the sustainable development of the food industry with high energy consumption, especially in the table grapes cold chain. The aim of this paper is to propose a profit maximization strategy of table grapes cold chain by integrating the carbon footprint to improve the low-carbon production and sustainability of the cold chain system. The carbon footprint was evaluated by life cycle assessment (LCA) in entire cold chain system of table grapes, and the economic order quantity (EOQ) model was used to develop the profit maximization model with minimal carbon footprint and to maintain the optimal balance between stock and cost. The profit optimization performance, the sensitivity performance and the influencing factors of the decay rate, the carbon emission price, and the distance and carbon emission coefficient in refrigerated transport were analyzed according to the profit maximization model and the inventory data in actual cold chain investigated. The sensitivity performance analysis illustrated that the selling price had the highest sensitivity, and the carbon emission coefficient in storage had the lowest sensitivity. The comprehensive analysis results indicated that there is an optimal combination point between the economy and environment in actual cold chain, which not only reduced the carbon emission, but also had minimal impact on the profit in cold chain. The enterprises should integrate the carbon footprint cost into the profit maximization once the carbon emission tax is levied. The proposed strategy of the profit maximization with carbon footprint constraint is also suitable for improving profit maximization of other low-carbon supply chain applications.

Anthropogenic greenhouse gas emissions need to be cut to limit climate change. Thus, universities, in the same way as citizens and companies, are starting to raise awareness about this issue and to take action to reduce their carbon footprint. Centrale Nantes, a French “Grande école”, initiated a low carbon transition with the calculation of the 2018 carbon footprint of the university. This report presents an individual carbon footprint estimator developed within the scope of the university, based on the new open-source French national simulator called “Nos Gestes Climat” proposed by ABC (Association Bilan Carbone (Association for the implementation of Carbon footprint assessment)) and ADEME (French Environment and Energy Management Agency). Development context and important features of the national version are described. Then, to meet university user’s expectations, feedback from a panel of testers has been collected in order to guide the declination development and promote good practices ensuring user engagement. The transparency of the data model, the accurate explanations, the variety of actions have been found to be key success factors for the development and the adoption of such a simulator. Results also suggested that users are keen to involve themselves in the university initiative to reach carbon neutrality.

The article deals with the key aspects of the problem of determining the “carbon footprint” of industrial production. Rapidly increasing greenhouse gas emission within the past two centuries can cause irreversible changes in the Earth’s climate. Various manufacturing industries including “production and consumption of energy” create more than half of the “Earth’s carbon footprint”. The authors present a brief analytical overview of the “carbon footprint” problem in the context of solving a significant issue of global warming. They suggest references to current research and publications of Italian, Chinese and Spanish scientists. For example, Italian researchers proved that social innovations as well as transition to low-carbon technologies can be of good effect in reducing the “carbon footprint”. Chinese researchers (by analyzing 45-year-long data on the quantity of developed natural resources, energy consumption and population growth, “carbon footprint” and carbon dioxide emissions in the USA) proved that in the long-term perspective consumption of natural resources and renewable energy sources can improve the quality of the environment while population growth and consumption of non-renewable energy sources can contribute to its deterioration. Spanish researchers explored the connection between the “carbon footprint” and national peculiarities of people’s life. They listed the basic features of current energy transformation of the global economy (towards increasing the volume of renewable energy sources). The authors considered basic methods of regulating the “carbon footprint” of industrial production: by means of legal prohibition or improvement of pricing mechanism. They introduce the “Strategy of long-term development of Russia with low level of greenhouse gases till 2050”. The article contains information on reporting of greenhouse gas emissions in Russia.

Abstract Construction Industry indicates development of the country and it helps in the economic growth which adds productivity and quality of life of citizens. During the manufacturing and the construction processes, there is use and combustion of fossil fuels which results total 39% of total carbon footprint. So, studying carbon footprint for construction companies becomes very important. Many different studies are carried out with giving number of alternatives to reduce the amount of carbon footprint. However, this research is focused mainly on multi-storeyed residential building in renowned city in India, shows the carbon emissions produced by a construction activity right from the material production to the actual execution process. Different Greenhouse gases contributing carbon footprint were also studied & incorporated. Various activities accounting to emissions were listed and their carbon footprint value (in the form of Carbon Dioxide equivalent) was calculated by bottom-up method. The manufacturing of various construction materials and usage of electricity during execution phases of a building causes very bad impact on the environment. The greatest contributors of the carbon footprint are onsite electricity use and building materials manufacturing. Therefore, use of green concrete, renewable energy, prefabricated construction materials and low emission construction equipment & vehicles can help in reducing the values of Carbon Footprint by the construction industry.
