About Environmental Defense Fund

The Environmental Defense Fund 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.

By leveraging our deep expertise in science and economics, EDF delivers bold, game-changing solutions to address the biggest challenge of our time — climate change.

We work to stabilize the climate, strengthen the ability of people and nature to thrive and support people's health. Working in more than 30 countries, we focus on the areas where we can make the biggest impact. From slashing pollution from transportation around the world, to slowing the warming we're experiencing now by cutting methane pollution, to bolstering nature's own capacity to stabilize the climate.

We partner with other organizations — as well as with businesses, governments and communities — to get the world on a rapid path to climate stability.
