CCS Documents Role of Economy, Specific Policy Actions In Driving Major Decline in US Emissions, Energy Shifts

According to new analysis released by CCS on November 30, 2011, projected US emissions of carbon dioxide have fallen 69 percent in relation to 1990 levels compared to previous estimates made since 2005. National emissions now are projected to match 2000 levels by 2020. New baseline decomposition analysis by CCS shows that 80 percent of these reductions are driven by specific, sector-based policy actions at the subnational and national levels. An estimated 20 percent of the reductions are due to changes in the economy. Energy prices were not found to be a major factor, but contributed to a significant shift in electricity generation from coal to natural gas. CCS has developed and is making available a new baseline decomposition tool for policy makers to support local, state and national evaluation of past trends, including documentation of specific policy benefits.
