Environmental Defense Fund's mission is to preserve the natural systems on which all life depends.

Guided by science and economics, we find practical and lasting solutions to the most serious environmental problems.

What distinguishes Environmental Defense Fund is the combination of what we protect and how we protect it.

We work to solve the most critical environmental problems facing the planet. This has drawn us to areas that span the biosphere: climate, oceans, ecosystems and health. Since these topics are intertwined, our solutions take a multidisciplinary approach. We work in concert with other organizations — as well as with business, government and communities — and avoid duplicating work already being done effectively by others.

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.

Today, we work with members of Congress from both parties to 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:

• Driving the science and advocacy that led to federal action toward reducing climate-harming methane emissions
• Introducing a management system that has dramatically reduced the amount of overfishing in the United States
• Persuading companies, such as Walmart and McDonald's, to adopt environmentally friendly business practices
