Climate Action Reserve



The Climate Action Reserve (“Reserve”) is an independent nonprofit organization based in California that has been at the forefront of greenhouse gas (GHG) quantification and climate policy. Established by an act of the California legislature in 2001, the Reserve works to ensure environmental benefit, integrity and transparency in market-based solutions to address global climate change. It operates the largest accredited carbon offset registry for California’s cap-and-trade program, and has played an integral role in informing the regulatory program’s development and administration. The Reserve also promotes corporate action on climate change through its voluntary carbon offset program, for which it establishes high quality standards for carbon offset projects, oversees independent third-party verification bodies, issues carbon credits generated from such projects and tracks the transaction of credits over time in a transparent, publicly-accessible system.

The Reserve offsets program demonstrates that high-quality carbon offsets foster real reductions in GHG pollution, support activities that reduce local air pollution, spur growth in new green technologies and allow emission reduction goals to be met at lower cost. The Reserve has certified more than 60 million carbon offset credits from projects throughout the United States and Mexico.

The Reserve’s programs and services are designed to ensure the credibility and value of carbon markets in North America and around the world.
