About The Climate Registry

The Climate Registry (TCR) is a non-profit organization that empowers North American organizations to do more in the fight against climate change by providing services and tools that help them reduce their emissions. TCR also drives climate action and ambition on the road to net zero by recognizing and showcasing sub-national leadership, and by building strategic partnerships with and between national and international entities. TCR is advised by a Council of Jurisdictions that includes representatives from diverse U.S. states and Canadian provinces and territories.

Our Vision

To make global warming history.

Our Mission

The Climate Registry empowers our generation to reduce its carbon footprint.


Established in 2007, The Climate Registry was formed to continue the work of the California Climate Action Registry (CCAR). Created by the State of California in 2001, CCAR promoted and protected businesses’ early actions to manage and reduce their greenhouse gas (GHG) emissions. Through the state mandate, CCAR established protocols to guide emissions inventories and manage an online reporting tool, the Climate Action Registry Reporting Tool (CARROT), to serve as a central database for emissions reports.  Members of CCAR served as true leaders in environmental responsibility and were among the first in the world to measure their emissions according to comprehensive and rigorous standards and make their emissions publicly accessible online. Together, CCAR and its members influenced California climate change policy, including Assembly Bill 32 (AB 32), and worked to ensure proper recognition from the state for early actions to reduce emissions.  Recognizing climate change is a global issue and that success in emissions reporting must be based on consistent data in an integrated system that stretched beyond California’s borders, CCAR was instrumental in establishing TCR with the mission of expanding CCAR’s emissions reporting work to include all of North America.  CCAR accepted its last emissions inventory reports for 2009 in December 2010 and officially transitioned its members to The Climate Registry.  CCAR is now a program of The Climate Registry’s sister organization, the Climate Action Reserve.
