Climate Change


The Climate Registry

On May 8, 2007, Delaware signed on as a charter member of The Climate Registry (TCR), a 501(c)(3) nonprofit organization dedicated to developing a consistent and accurate greenhouse gas (GHG) emissions tracking system.

Delaware joined TCR along with 30 other U.S. States and one Tribal Nation. The program has continued to grow, and since that time, nine additional U.S. States, the District of Columba, one Mexican State, and two additional Tribal Nations have joined the program (See the Climate Registry web site for the most up-to-date list of members).


The Climate Registry is a voluntary collaboration between states, tribes, and provinces “aimed at developing and managing a common greenhouse gas (GHG) emissions reporting system with high integrity.” The Registry will measure, track, verify and publicly report GHG emissions from members in an accurate and transparent manner.


Members must agree to calculate, certify, and publicly report their greenhouse gas emissions annually by (1) identifying all sources of GHG emissions, (2) calculating emissions according to set protocols, (3) verifying their emissions with an approved third-party contractor, and (4) reporting the verified data to the public via The Climate Registry’s web site.



The Climate Registry incorporated the California Climate Action Registry (CCAR), the Eastern Climate Registry, the Western Regional Air Partnership, and the Lake Michigan Air Directors Consortium (LADCO), “making it the largest State- and Province-based effort to date to track greenhouse gas emissions (EIA, 2007).” It is set to officially launch in January, 2008.
