This figure 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.

For a full discussion of underlying methodology, assumptions and references, please see WRI does not endorse any of these bills. This analysis is intended to fairly and accurately compare explicit carbon caps in Congressional climate proposals and uses underlying data that may differ from other analyses. Price caps and circuit breakers contained in some bills may allow emissions to exceed what is depicted in this analysis.
