Temperature stabilization requires that CO2 emissions be limited to less than 3 Gt Carbon equivalent, from the present level of more than 6 Gt. Despite an increase of primary energy demand by 250% in 2050 we find that a nuclear intensive scenario assuming the development of a 3000 GWe pool of PWR reactors by 2030 and of an additional 6000 GWe pool of U-Pu or Th-U reactors by 2050 would lead to ...

The air quality impacts of replacing approximately 20% of the gasoline-powered light duty vehicle miles traveled (VMT) with electric VMT by the year 2018 were examined for four major cities in Texas: Dallas/Ft Worth, Houston, Austin, and San Antonio. Plug-in hybrid electric vehicle (PHEV) charging was assumed to occur on the electric grid controlled by the Electricity Reliability Council of Tex...

Adoption of mitigation measures to reduce greenhouse gas emissions may affect other members of the society, producing a situation of trade-offs. In this study, such a trade-off is has been analyzed using three aspects of the Canadian society: producers (farm level adopter), environment (through reduction in the GHG emissions),; and regional economy (including rest of the society through lost / ...

We examine the implications of school choice on walkability, school travel mode and overall environmental emissions. In developing this proof-of-concept model we show—and quantify—differences between city-wide schools and their neighborhood school counterpart. Our analysis demonstrates how children attending city-wide schools may have heightened travel distance, greenhouse gas emissions, and ex...

China continues its strategy of total emissions control (TEC) or total load control for SO2 in the Tenth Five Years (2001~2005). This paper will analyze the status of SO2 TEC in China during the Ninth Five-Years (1996~2000). Based on the results of the analysis and the theory of divisional air resources, this paper will study the target of total SO2 emissions nationwide and its allocation for d...

Study was conducted for the projection of energy demand and emission analysis for the next thirty years, taking the 2000 as a base year. This has been determined with the help of the Long Range Energy Alternative planning system (LEAP). It forecasted the energy consumption and environmental emissions in industrial area of Islamabad. All available energy consumption activities and socio-economic...

A model of carbon dioxide emissions of the USA is presented. The model consists of population, income per capita, economic structure, final and primary energy intensity per sector, primary fuel mix, and emission coefficients. The model is simple enough to be calibrated to observations since 1850. The model is used to project emissions until 2100. Best guess carbon dioxide emissions are in the m...

Projections of future climate change depend upon future anthropogenic greenhouse gas emissions. In preparation for its Fifth Assessment Report, the Intergovernmental Panel on Climate Change implemented a new approach to generating emissions scenarios, called ‘Representative Concentration Pathways’ (RCPs), which replace the scenarios in the ‘Special Report on Emissions Scenarios’ (SRES). The RCP...

A system dynamics model based on the dynamic interactions among a number of system components is developed to estimate CO(2) emissions from the cement industry in India. The CO(2) emissions are projected to reach 396.89 million tonnes by the year 2020 if the existing cement making technological options are followed. Policy options of population growth stabilisation, energy conservation and stru...
