WASHINGTON - Researchers at Resources for the Future have prepared a detailed comparison of major market-based climate change proposals currently under consideration in the 110th Congress.

The matrix is designed to allow policymakers to have a provision-by-provision assessment of the key differences in each bill, according to Ray Kopp, RFF Senior Fellow.

"Committees and individuals in both the House and Senate have introduced a range of ideas in the various pieces of legislation being considered," says Kopp. "We believe this chart will enable those following the progress of the legislative process to easily contrast and highlight the differences in each bill."
