Forging the way forward

For decades, EDF has been committed to bipartisan environmentalism. The results are incontestable: Every major environmental law from the early 1970s to 2016 has passed with support of both Democrats and Republicans.

In 2017 – our 50th year – we will work with members of Congress from both parties who, like us, resist attacks against America’s bedrock environmental laws.

We’ll continue to find innovative ways to solve big environmental problems in the U.S. and globally. Among our successes, we’ve played key roles in:
