Earthworks is an environmentalist nonprofit organization based in Washington, D.C. that advocates for strict environmental regulations, particularly on the fuel and mining industries.
Earthworks was formed from the merger of the Mineral Policy Center and the Oil and Gas Accountability Project in April 1988. 
The organization, which advocates for strict environmentalist regulations, has four program areas: “Fighting Mining Injustice,” which focuses on the mining and minerals industry; “Ending Oil & Gas Expansion,” which focuses on fuel producers and distributors, and supports local campaigns and protests; “Protecting Climate from Oil & Gas Methane Pollution,” which studies environmental pollution allegedly resulting from fuel production and use and advocates for state and federal regulations limiting their prevalence; and “Making Clean Energy Clean, Just and Equitable,” which focuses on advocacy for alternatives to conventional fuels and mineral resources and recycling practices. 
Earthworks criticized the Biden administration’s announcement that the President would issue an executive order pursuant to the Defense Production Act to secure reliable supply chains for minerals used in electric vehicle batteries by facilitating the recycling of old batteries, re-mining waste from existing mines, and supporting newly permitted mines.  Among other things, the organization’s statement noted that President Joe Biden’s use of the Defense Production Act would add “ to the generational trauma experienced by mining affected communities, particularly Indigenous communities.” 
On April 26, 2022, Earthworks joined a coalition of environmentalist organizations, including Cultural Survival, EarthJustice, Friends of the Earth, Global Witness, Oxfam America, the Sierra Club, the Wilderness Society, Wild Connections, and New Energy Nexus, in sending a letter to members of Congress in support of the Clean Energy Mineral Reform Act sponsored by Rep. Raul M. Grijalva (D-AZ).   If passed, the bill would prohibit the issuance of specified mining patents, establish a 12.5 percent royalty on new mining operations and an eight percent royalty on existing operations, and increase compliance requirements for the mining exploration permit process. As of April 27, 2022, the bill was referred to the Subcommittee for Indigenous Peoples of the United States of the House Natural Resources Committee. 
On June 30, 2022, following the release of the Supreme Court of the United States decision in West Virginia v. Environmental Protection Agency concerning the power of the EPA to regulate carbon dioxide emissions under the Clean Air Act, which found in favor of West Virginia, Earthworks policy director Lauren Pagel asserting that President Biden “must now declare” a climate emergency. As part of this declaration, Pagel advised that the Biden administration “begin denying permits for oil and gas infrastructure.” 
On September 12, 2022, Earthworks published a statement in support of a letter opposing an amendment to the Inflation Reduction Act proposed by Sen. Joe Manchin (D-WV). The proposal, which the letter dubbed “a side deal,” would reduce regulatory strictures on companies involved in mineral extraction, provide for accelerated federal review of proposed projects, and set the scope of federally mandated environmental study entailed in the project approval process. Pieces of legislation supported in the letter include the Environmental Justice for All Act and Requirements, Expectations, and Standard Procedures for Effective Consultation with Tribes (RESPECT) Act proposed by Grijalva and Rep. Donald A. McEachin (D-VA). 
On September 13, 2022, Earthworks published a post in support of a petition urging the Biden administration to reject the application for the Sea Port Oil Terminal, a new fuel venture in Brazoria and Harris counties in Texas. According to Earthworks, the venture, which produces two million barrels of crude oil per day for global export, would increase pollution in the Houston-Galveston-Brazoria region. Other organizations supporting the petition, including Citizens for Clean Air and Water in Brazoria County, the Texas Campaign for the Environment, the Sierra Club, and the Turtle Island Restoration Network. 
Organizations that have provided over $10,000 in funding to Earthworks include the Aria Foundation, Chorus Foundation, Civil Society Institute, Colcom Foundation, Environmental Defense Fund, Energy Action Fund, Leaves of Grass Fund, Lisa and Douglas Goldman Fund, New-Land Foundation, Overbrook Foundation, Partnership Project, Patagonia Org, Proteus Fund, Rockefeller Brothers Fund, Scherman Foundation, Schmidt Family Foundation, Threshold Foundation, Tiffany & Co. Foundation, and Wyss Foundation.

Previously, Krill was a campaign director at the Rainforest Action Network, an environmentalist organization focused on the conservation of old growth forests. 
Rachel Kerr has the been the energy program director of Earthworks since January 2022. Previously, Kerr worked in programming with the Alliance of Nurses for Healthy Environments, and as a hospital nurse.
