Background: Greenhouse gas (GHG) emissions are increasing worldwide. They have harmful effects on human health, animals, and plants and play a major role in global warming and acid rain. Methods: This research investigated carbon dioxide (CO2) and CH4 emissions obtained from different parts of the Hakim Farabi, Dobal Khazaei, and Ramin factories which produce ethanol and yeast. Seasonal rates ...

BACKGROUND Global warming is attracting attention from policy makers due to its impacts such as floods, extreme weather, increases in temperature by 0.7°C, heat waves, storms, etc. These disasters result in loss of human life and billions of dollars in property. Global warming is believed to be caused by the emissions of greenhouse gases due to human activities including the emissions of carbon...

co2 emissions from combustion flue gases have turned into a major factor in global warming. post-combustion carbon capture (pcc) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas co2. to test a new solvent (ait600) for this purpose, a small pilot plant was used. this paper presents the results of studies on chemical methods of...

SEAB has approved the report of the Task Force on CO2 Utilization at its public meeting of December 12, 2016 and is hereby transmitting it to you. Your charge to the Task Force was to describe a framework for a DOE RD&D program on CO2 utilization technologies that has the potential to reduce CO2 emissions and/or introduce negative emissions at the gigatonne scale. The Task Force, under the lead...

Introduction According to the Fourth IPCC Assessment Report on Climate Change (AR4), anthropogenic greenhouse gas (GHG) emissions are responsible for a major part of the observed global warming over the past 50 years. In addition carbon dioxide (CO2), released from the burning of fossil fuels and biomass (e.g. burning of forest for land clearance) is recognized as the most important anthropogen...

Recent studies have suggested that global mean surface temperature would remain approximately constant on multicentury timescales after CO2 emissions1–9 are stopped. Here we use Earth system model simulations of such a stoppage to demonstrate that in some models, surface temperature may actually increase on multi-century timescales after an initial century-long decrease. This occurs in spite of...

In an effort to address global warming, rich countries appear willing to reduce their own emissions of carbon dioxide and other greenhouse gases (hereafter subsumed under the umbrella of CO2) by upwards of 80% or more by 2050, with the proviso that overall global emissions decline by 50%. One important justification for such targets is the notion that global warming will hurt the poorest people...

the goal of this study was to analysis the greenhouse gas (ghg) emissions of pasta production. data for this study was collected from durum wheat farms of three provinces of iran. data of soil properties, transportation and pasta factory stages were collected and analyzed, using simapro software, ecoinvent data base and global warming potential (gwp) 100 years method. epic model was used to cal...

Previous studies have demonstrated the importance of enhanced vegetation growth under future elevated atmospheric CO2 for 21st century climate warming. Surprisingly no study has completed an analogous assessment for the historical period, during which emissions of greenhouse gases increased rapidly and land-use changes (LUC) dramatically altered terrestrial carbon sources and sinks. Using the G...
