Resumen
Biomass heating is used more and more by the greenhouse industry to reduce costs and the environmental footprint of production. The objective of this research project was to investigate the possibility of using the carbon dioxide (CO2) from the exhaust gas of a biomass heating system to enrich greenhouses with CO2 and improve crop yield. When compared to direct combustion, biomass gasification technology offers better control, which helps in reducing atmospheric emissions. Gasification is a thermo-chemical reaction, which converts solid biomass into a gaseous fuel, known as syngas. Experiments

This project aims at investigating the effect of CO2 enrichment on the growth and gas exchange of C3, C3-C4 and C4 Panicum grasses. Potted plants were grown in soil under well watered conditions, in artificially lit environmentally controlled cabinets or naturally lit greenhouses at varying levels of CO2 enrichment. CO2 enrichment enhanced the dry weight of C3 and C4 Panicum species under optimal light and N supplies, but had no effect on the total leaf N or TNC concentrations.

Resumen
Atmospheric CO2 concentration ([CO2]) has increased over the last 250 years, mainly due to human activities. Of total anthropogenic emissions, almost 31% has been sequestered by the terrestrial biosphere. A considerable contribution to this sink comes from temperate and boreal forest ecosystems of the northern hemisphere, which contain a large amount of carbon (C) stored as biomass and soil organic matter. Several potential drivers for this forest C sequestration have been proposed, including increasing atmospheric [CO2], temperature, nitrogen (N) deposition and changes in management practices

Resumen
Previous studies on dwarf bean plants have found a very limited growth response to CO₂ enrichment (Jolliffe and Ehret, 1985; Ehret and Jolliffe, 1985b). There was no increase in leaf area, and leaf injury was observed after about three weeks of CO₂ enrichment (Ehret and Jolliffe, 1985a). Although dry weight was increased, the increase may be limited due to restricted carbon utilization (e.g. no increases in leaf area). In this study, non-photosynthetic limitations, such as the partitioning of dry matter among plant parts, the partitioning of carbon among photosynthetic end products, and the in

Resumen
Atmospheric CO₂ enrichment is employed by greenhouse tomato growers to increase fruit yields, and CO₂ applications are managed according to atmospheric set points or CO₂ injection rates. These methods do not immediately focus on the targets of CO₂ applications: plant performance and the regulation of plant carbon status. This thesis explores several plant-based approaches that may have potential for use in the management of CO₂ in greenhouse tomato production. Three plant-based approaches to CO₂ management were explored in commercial and experimental tomato greenhouses. These were: (1) si

Resumen
Oceans absorb 30% of the anthropogenic CO2 release in the atmosphere (IPCC 2014). With climate change, marine ecosystems are mainly exposed to rising temperature and ocean acidification. The principal consequences of adding CO2 to seawater is to decrease the concentration of carbonate ion and lower pH. These impacts can affect marine calcifying organisms such as bivalves to produce their CaCO3 shell or compromise their fitness. The IPCC proposes Carbon dioxide Capture and Storage (CCS) in the context of a measure for mitigating climate change consequences, however a leakage of CO2 could have n
