Carbon Trading and Offsets

SEI is providing guidance for the potential development of a U.S. carbon offset program as part of a future mandatory GHG compliance regime. SEI has done extensive research on mandatory and voluntary carbon offset programs and cap-and-trade systems.

All of our papers on the topic and extensive information about carbon offsetting can be found on our website: www.co2offsetresearch.org

The site is maintained by SEI's Carbon Offset Research and Education (CORE) Initiative. It provides an up-to-date analysis and synthesis of the most influential offset programs and activities. It reflects on lessons learned, and aims to inform consumers as well as participants and designers of current and future offset programs.

The site is divided into three sections which are interlinked:

Policy Information
- provides in-depth analysis and information about offset design and policies.

Consumer Information
- provides information relevant to offset buyers and offers an introduction to the world of carbon offsetting.

Aviation Information - provides an introduction to the issues related to GHG calculations from aviation for carbon offsetting.
