The origin
How they started
Earthworks takes on the mining, oil, and gas industries that scar public land, pushing to reform hardrock mining law and cut methane pollution from drilling on federal acres. It traces back to the Mineral Policy Center, founded in 1988 by former Interior Secretary Stewart Udall and others, which rebranded as Earthworks in 2004 and later combined with the Oil & Gas Accountability Project. It works alongside the communities living next to extraction sites, documenting pollution and pressing regulators to act. Based in Washington, DC.

The people
Who does the work
Honesty note: leadership comes from each year’s federal filing, so it can run a year behind. The FY2025 filing lists two people as executive director, Jennifer Krill and Michelle Medeiros, usually a handover inside the year. If it’s out of date, tell us. Work at Earthworks? Claim this page.
