A comparison of legislative climate change targets in the 110th congress
The World Resources Institute’s analysis of emissions targets and cumulative emissions budgets attempts to objectively, fairly and accurately compare GHG reductions from explicit carbon caps and complementary policies contained in climate proposals submitted in the 110th Congress. Emissions from capped sectors are calculated based on the text of the respective legislation. For sectors that are not covered by the legislation, emissions are estimated to continue uncontrolled in line with projections published by EPA. This analysis uses a single set of carefully selected data and methods to provide a consistent comparison across all climate proposals in the 110th Congress. This analysis is not a projection of actual future emissions under the various proposals nor is it an analysis of economic impacts resulting from the enactment of these policies.
“Comparison of Legislative Climate Change Targets in the 110th Congress” compares targets for legislative proposals of mandatory cap and trade programs for greenhouse gas emissions. Specifically, each line reflects the mandatory caps plus the growth in uncovered emissions as well as a range of additional possible reductions that could occur through complementary policies. Appendix 1 contains a table that includes the underlying data and estimates of emission reductions for selected years. This chart is a revision of a similar analysis by World Resources Institute released during the 109th Congress and subsequently updated through June 4, 2008.
