How Realistic Are Expectations for the Role of Greenhouse Gas Offsets in U.S. Climate Policy?

A sound understanding of the economics of offsets-in particular, of the potential supply of offsets under future policy scenarios and market conditions-is critically important for policymakers as they address major design decisions in crafting climate policy. This analysis will evaluate offset supply analyses completed to date, with a particular focus on identification of the assumptions and discrepancies of these efforts. This work will inform a subsequent, detailed analysis of domestic offset supply potential.
