Methane (CH4), carbon dioxide (CO2), nitrous oxide (N2O), and halocarbons are greenhouse gases (GHG) that are able to trap heat in the atmosphere by radiating less heat into the space and increase the effect of solar and thermal radiation on surface and atmospheric temperatures (Knapp et al., 2014). In 2014, total U.S. GHG emissions measured 6,870 million metric tons of CO2 equivalents. Agricul...

Greenhouse gas (GHG) emissions resulting from the Land Use, Land-Use Change, and Forestry sector (LULUCF) are estimated and reported in National Communications to the United Nations Framework Convention on Climate Change (UNFCCC). By definition, the LULUCF sector is a “greenhouse gas (GHG) inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induce...

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...

Large residential areas in Sweden and elsewhere are facing a need for renovation. Swedish buildings from the record year era (1961 – 1974) are now 40 – 55 years old and in many cases in need of extensive renovation measures. This need for renovation could be seen as an important opportunity to achieve overarching sustainability target levels and to perform renovation with a holistic approach. T...

This paper develops a CGE model with unique regional land types and detailed non-CO2 GHG emissions which it uses to analyze the potential for reductions in land-based greenhouse gas emissions as well as forest sequestration. In our global, general equilibrium analysis of carbon taxation, we find that forest carbon sequestration is the dominant means for global GHG emissions reduction in the lan...

Sheep production in Canada is a small industry in comparison to other livestock systems. Because of the potential for expansion of the sheep industry in Canada, the GHG emissions budget of this industry was assessed in this paper. The GHG emissions from Canadian lamb production were compared with those from the Canadian beef industry using the ULICEES model. The GHG emission intensity of the Ca...

Reactive N (Nr) releases are closely linked with greenhouse gas (GHG) emissions, and the simultaneous evaluation of them can help to develop overall effective mitigation options. In this study, we evaluated the characteristics of the Nr and GHG releases from staple food (rice, flour and corn-based fodder) production in China (2001-2010) and explored their mitigation potential. Results showed th...

The Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model incorporated fuel economy and electricity use of alternative fuel/vehicle systems simulated by the Powertrain System Analysis Toolkit (PSAT) to conduct a well-to-wheels (WTW) analysis of energy use and greenhouse gas (GHG) emissions of plug-in hybrid electric vehicles (PHEVs). Based on PSAT simulations of ...

This paper examines policy and technology scenarios in California, emphasizing greenhouse gas (GHG) emissions in 2020 and 2030. Using CALGAPS, a new, validated model simulating GHG and criteria pollutant emissions in California from 2010 to 2050, four scenarios were developed: Committed Policies (S1), Uncommitted Policies (S2), Potential Policy and Technology Futures (S3), and Counterfactual (S...

Total uncertainty in greenhouse gas (GHG) emissions changes over time due to “learning” and structural changes in GHG emissions. Understanding the uncertainty in GHG emissions over time is very important to better communicate uncertainty and to improve the setting of emission targets in the future. This is a diagnostic study divided into two parts. The first part analyses the historical change ...
