Environmental Law Program

The Environmental Law Program uses strategic legal campaigns to fight climate change, to protect clean air, water and wilderness, and to promote justice for communities threatened by pollution.


In the past year alone, we launched more than 200 legal actions to challenge the fossil fuel industry's destructive effects on our air, water, and climate.

Our team of top-notch attorneys and legal staff leverages all of the Club's tools of democracy, integrating legal advocacy with grassroots organizing, sophisticated communications, a state-of-the-art digital strategies team, and administrative lobbying.
