League of Conservation Voters

The League of Conservation Voters (LCV) is a prominent environmental advocacy and political organization founded in 1969. LCV works to turn environmental values into national priorities by influencing elections and policy: it publishes the National Environmental Scorecard rating lawmakers’ votes, lobbies for strong environmental protections, and through its affiliated PACs supports pro-environment candidates. LCV and its state affiliates mobilize voters, run issue campaigns on climate and conservation, and have helped secure victories such as passing stronger clean air and water laws and defending public lands.
