U.S. Climate Action Network (US-CAN) is an environmentalist advocacy organization based in Washington, D.C. and the national affiliate of Climate Action Network International (CAN-I). The organization uses tactics such as protests, policy advocacy, and smear campaigns to support environmentalist advocacy campaigns. The organization lists many left-leaning and progressive organizations as coalition “members” and conveys a left-of-center viewpoint on environmentalism.
US-CAN advertises memberships with other environmentalist organizations that it claims “fight climate change in a just and equitable way.” Member organizations include many left-leaning organizations such as the Service Employees International Union, Center for American Progress, 350.org, Greenpeace, NAACP, Oxfam America, and Sierra Club. 
People’s Climate March
The People’s Climate March is an organized protest that occurs in multiple U.S. cities annually. Organized by People’s Climate Movement, the organization claims that hundreds of thousands of protesters marched in such cities as San Francisco, Washington D.C., and more in the 2018 march. More than half of the organizations involved with or sponsoring the march were members of US-CAN as of 2017 according to US-CAN annual reports.  
Paris Climate Accord
During the Paris Climate Accord in 2015 and 2016, US-CAN activists worked alongside those of Avaaz, another left-leaning environmentalist organization, pasted “wanted posters” that showed opponents of the U.N.-backed environmental agreement in a mugshot-like fashion around Paris. Writers for the Competitive Enterprise Institute, Heartland Institute, and other conservative think-tanks were portrayed along with Benjamin Sporton, an Australian coal executive, and Bjorn Lomborg, a Danish skeptic of environmentalist policy priorities. 
US-CAN announced a 5-year plan lasting from 2017 to 2022 with the goal of growing its network of member organizations to be able to further spread its message. The goals have less to do with environmental activism than growing the list of member organizations and reforming the leadership of the network.
