The California Climate Action Registry


The California Climate Action Registry accepted its last emissions inventory reports and officially closed in December 2010. The California Registry recognized that success in emissions reporting must be based on consistent data in an integrated system that stretches beyond California’s borders. Thus, it has been transitioning its members to The Climate Registry. The California Registry will continue to maintain emissions data from members’ pioneering voluntary early action commitments in perpetuity on this website.

The Climate Registry is a nonprofit collaboration among North American states, provinces, territories and Native Sovereign Nations that sets consistent and transparent standards to calculate, verify and publicly report greenhouse gas emissions into a single registry.
