The Chesapeake Climate Action Network, is the Capital Area chapter of U.S. Climate Action Network and Climate Action Network-International (CAN-I). It was founded in July 2002 with a seed grant from the Rockefeller Brothers Fund. USCAN is the national affiliate of Climate Action Network International, a global conglomerate of over 1100 environmentalist groups.
CCAN has spent time lobbying Washington politicians. In 2015, the organization hired lobbyist Kenneth Forsberg to lobby in support of HR 1027 (called The Healthy Climate and Family Security Act of 2015) which aimed to reduce the use of fossil fuels during the production of goods and services by imposing taxes and requiring companies to purchase government permits. CCAN is well known in the D.C. area for its aggressive leftism: The Washington Post noted that anti-Trump Administration groups were raising funds for its D.C. area operations.  The organization has challenged and protested the Washington Nationals for receiving financial support from ExxonMobil. Exxon’s funds were directly supporting the promotion of a more environmentally friendly stadium.
CCAN’s methods of climate alarmism are controversial even within the environmentalist community. The anti-corporate environmentalist publication Desmogblog called out CCAN’s director, Mike Tidwell, in a multipart critique challenging his “misuse of science to serve political ends.” Further, Desmogblog suggested Tidwell’s activism would inspire people “to take counterproductive actions.” CCAN has feuded with other environmentalists about wind energy.
CCAN activists have a record of controversial demonstrations. Protests like one involving dumping coal on U.S. Capitol property caused police to log Tidwell and other members of CCAN in a database as being “suspected of involvement in terrorism” for a 13 month stretch, though no charges were ultimately filed.
Chesapeake Climate Action Network lists numerous groups as “Allied Organizations.”  They include:
