Lawsuit Against the Repeal of the Endangerment Finding
California Governor Gavin Newsom has announced a lawsuit against the Trump administration following the repeal of the U.S. Environmental Protection Agency's (EPA) 2009 Endangerment Finding. This finding, established during the George W. Bush administration, recognized that greenhouse gas emissions pose a threat to public health and welfare, serving as the legal foundation for federal climate regulations for over fifteen years. Newsom characterized the repeal as unlawful and detrimental, stating, “Donald Trump is breaking the laws that protect Americans from climate pollution—all to enrich his Big Oil and his wealthy polluting allies.”
Attorney General Rob Bonta emphasized that the repeal represents a significant abandonment of the federal government's responsibility to safeguard public health. He stated, “With the unlawful rescission of the Endangerment Finding, President Trump and his EPA have abandoned their most important mission: protecting the health and welfare of the American people.” Bonta highlighted the established scientific consensus linking greenhouse gas emissions to climate-related disasters, including wildfires and floods.
Impacts of the Repeal
The lawsuit argues that the repeal will exacerbate climate-related hazards, leading to increased wildfires, extreme heat fatalities, and climate-driven floods. In California, rising temperatures have already resulted in severe consequences, including hundreds of deaths and extensive property damage. The state has experienced a 21% reduction in greenhouse gas emissions since 2000, even as its economy has grown significantly, showcasing its commitment to climate action.
The Trump administration's actions have been criticized for prioritizing the interests of the fossil fuel industry over public health. Critics argue that the administration has systematically weakened environmental protections, including proposing weaker fuel economy standards and allowing coal-burning power plants to emit higher levels of toxic pollutants. These actions have raised concerns about the long-term implications for public health and the environment.
Broader Context of Climate Policy
The Endangerment Finding was affirmed by a landmark 2007 Supreme Court ruling, which established the EPA's authority to regulate greenhouse gases under the Clean Air Act. Following the Trump administration's announcement of its intent to repeal this finding in July 2025, California, along with 24 other states representing 55% of the U.S. population, formally opposed the proposal. The California Air Resources Board provided detailed comments challenging the validity of the studies used to justify the repeal.
Official Statements & Responses
California officials have expressed strong opposition to the Trump administration's climate policies. Yana Garcia, Secretary for Environmental Protection, stated, “The truth is that climate change presents immediate threats to human health and to our environment.” Dr. Rita Nguyen, California’s Assistant Health Officer, noted that climate change poses serious health risks, particularly during extreme heat events.
