How To Join

The California Climate Action Registry is now referring all emissions inventory reporting to its sister organization, The Climate Registry. If you are interested in reporting your greenhouse gas (GHG) emissions, please visit The Climate Registry’s site. To learn more about this transition of emissions reporting from the California Registry to The Climate Registry, please visit our list of FAQs.

The California Registry will continue providing non-reporting member benefits through its new program, the Center for Climate Action. These benefits will include workshops, trainings, access to issue briefs and analysis, awards and webinars. Through the Center for Climate Action, California Registry members can remain leaders in influencing climate policy and initiatives in the U.S. To become a Partner of the Center for Climate Action, please visit the Center's website.
