Environmental Defense Fund

We began in 1967, as a scrappy group of scientists and a lawyer on Long Island, New York, fighting to save osprey from the toxic pesticide DDT. Using scientific evidence, our founders got DDT banned in the U.S.

Today, we’re one of the world’s top environmental organizations. We deliver bold solutions that cut climate pollution and strengthen the ability of people and nature to thrive — even with the climate change we feel right now.

And science still guides everything we do.
