Calculating Carma: Global Estimation of Co2 Emissions from the Power Sector

Forecast of CO2 Emissions From the U.S. Transportation Sector: Estimation From a Double Exponential Smoothing Model

The Transportation Research Forum, founded in 1958, is an independent, nonprofit organization of transportation professionals who conduct, use, and benefit from research. Its purpose is to provide an impartial meeting ground for carriers, shippers, government officials, consultants, university researchers, suppliers, and others seeking exchange of information and ideas related to both passenger...

Net CO2 Emissions from Global Photovoltaic Development

Implications of the recent reductions in natural gas prices for emissions of CO2 from the US power sector.

CO(2) emissions from the US power sector decreased by 8.76% in 2009 relative to 2008 contributing to a decrease over this period of 6.59% in overall US emissions of greenhouse gases. An econometric model, tuned to data reported for regional generation of US electricity, is used to diagnose factors responsible for the 2009 decrease. More than half of the reduction is attributed to a shift from g...

Economics of CO2 Emissions in Power Systems

The paper analyzes the economics of CO2 emissions in power systems by introducing concepts of marginal carbon intensity (MCI) of electricity demand and shadow carbon intensities (SCI) of binding transmission constraints. It demonstrates that values of MCIs are time and location dependent and exhibit properties similar to those of locational marginal prices of power. These concepts and their pro...

Continued global warming after CO2 emissions stoppage

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...
