# Earthjustice Founded in 1971 as the **Sierra Club Legal Defense Fund**, renamed Earthjustice in 1997. The largest public-interest environmental law firm in the United States, with **~225 attorneys** and offices nationwide. Tagline: *"Because the earth needs a good lawyer."* ## The Strategic Niche Earthjustice operates as the **legal arm of the broader environmental movement** — representing other environmental organizations, tribes, and affected communities in federal court. Unlike membership-based environmental organizations (Sierra Club, NRDC, EDF), Earthjustice's mandate is purely litigation. Unlike single-issue organizations (Center for Biological Diversity), Earthjustice handles cases across the full environmental-law spectrum: clean air, clean water, public lands, endangered species, environmental justice, climate. The model — strategic litigation across decades — is the load-bearing example of the [[Legal Strategy as Movement Infrastructure]] thesis applied to environmental rights. ## Trump 2.0 Track Record (2025–2026) The [[Trump 2.0]] EPA rollback has produced the most aggressive single-administration environmental-litigation docket in Earthjustice's history. ### The Endangerment Finding Repeal Challenge The defining case of 2026: Earthjustice represents nonprofits and Alaskan tribes in litigation challenging the **EPA's repeal of the 2009 Endangerment Finding** — the scientific determination that greenhouse gases endanger public health and welfare, which is the legal predicate for all federal climate regulation under the [[Clean Air Act]]. - **Final repeal rule published** February 18, 2026 - **Petition for review filed** in the D.C. Circuit immediately after - **Coalition includes** American Public Health Association, Natural Resources Defense Council, Environmental Defense Fund, and 15+ other groups - **Companion administrative reconsideration petition** filed by 16 health and environmental groups If the Endangerment Finding repeal stands, federal climate regulation under the Clean Air Act effectively ends. If the courts vacate the repeal, the Clean Air Act's climate-regulation framework remains structurally available to future administrations. The case is among the most consequential environmental-law cases since *Massachusetts v. EPA* (2007). ### Greenhouse Gas Reduction Fund Litigation With the Southern Environmental Law Center, Public Rights Project, and Lawyers for Good Government, Earthjustice sued the Trump administration for unlawfully terminating a **$3 billion EPA grant program** created by Congress in the [[Inflation Reduction Act]]. While a judge dismissed the lawsuit in **September 2025**, Earthjustice filed an appeal challenging that decision and continues to fight for communities that would benefit from the program. ### Vehicle Emissions Standards Multiple petitions for review filed against the EPA's repeal of light, medium, and heavy-duty vehicle climate standards. These cases will be consolidated with the Endangerment Finding litigation in the D.C. Circuit. ### Other Major Cases (2025–2026) - Title VI civil rights complaints over discriminatory permitting practices in low-income communities of color - Public lands litigation against expansion of fossil-fuel extraction on federal land - Tribal-rights litigation defending sovereign-nation environmental protections - Endangered Species Act listings and protections ## The Track Record The first Trump administration produced 163 NRDC lawsuits with a ~90% win rate. Earthjustice's track record is comparable. The pattern: **federal environmental statutes are durable; the regulatory architecture that operationalizes them is fragile but legally defensible**. Even a hostile administration cannot rewrite the Clean Air Act, the [[Clean Water Act]], the Endangered Species Act, or Title VI by executive action — and Earthjustice's job is to ensure that the formal text continues to constrain administrative-state choices. ## The Strategic Significance Earthjustice's institutional persistence is the operational example of the Resistance Hub's third thesis: **legal frameworks are both swords and shields**. The 1970s environmental statutes (Clean Air Act 1970, Clean Water Act 1972, ESA 1973) created both rights to regulate (sword) and defenses against rollback (shield). Earthjustice is the institutional infrastructure that wields the shield. ## See Also - [[Resistance Hub]] - [[Environmental Justice Movement]] — the movement Earthjustice litigates for - [[Legal Strategy as Movement Infrastructure]] — the strategic doctrine - [[ACLU]] — comparable litigation-as-resistance model in civil rights
