The Climate Registry (TCR) is a non-profit organization governed by U.S. states and Canadian provinces and territories.  TCR designs and operates voluntary and compliance GHG reporting programs globally, and assists organizations in measuring, reporting and verifying (MRV) the carbon in their operations in order to manage and reduce it. TCR also consults with governments nationally and internationallyon all aspects of GHG measurement, reporting, and verification.

They provide organizations with resources and hands-on, personalized support to help them report their GHG emissions in a publicly transparent and credible way. The Registry has more than 350 members who use our services to measure and manage their emissions, as well as share policy information and best practices in carbon management. The Registry supports both voluntary and mandatory reporting programs.

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.
