The Environmental Protection Agency announced Friday that deregulation measures enacted during President Trump’s second administration generated an estimated $1.6 trillion in compliance‑cost savings for the nation in the most recent fiscal year. The agency highlighted two flagship actions that drove the bulk of the savings.
Vehicle emissions rule rescinded
In early 2025 the EPA eliminated the 2009 Endangerment Finding, which had classified six greenhouse gases as a threat to public health and welfare and formed the basis for vehicle‑emissions standards under the Clean Air Act. By rescinding the finding and all related vehicle greenhouse‑gas requirements, the agency calculated more than $1.3 trillion in avoided costs, including roughly $2,400 per new vehicle. The agency described the move as the largest deregulatory action in U.S. history.
Power‑plant rules repealed
The second major action removed most of the Biden administration’s greenhouse‑gas requirements for power plants. The EPA estimates that this repeal will save about $310 billion in compliance costs over the next 20 years, marking the power sector’s biggest deregulatory step ever.
Congressional support
Congress played a key role in the deregulatory push. In 2025, lawmakers passed six Congressional Review Act resolutions that President Trump signed, nullifying prior EPA actions—including a rule implementing the Inflation Reduction Act’s methane fee and three California vehicle‑emission waivers. While the California waivers are currently being contested, the resolutions underscore bipartisan legislative backing for reducing regulatory burdens.
Legal challenges
Both the vehicle‑emissions rescission and the power‑plant repeal face lawsuits. Health and environmental groups, along with a coalition of states, have sued in the D.C. Circuit to overturn the Endangerment Finding rescission, and additional health groups are challenging the power‑plant repeal. The EPA maintains that the savings are real and that the rules were unnecessarily costly to businesses and consumers.
Context and clarification
FactCheck.org notes that the $1.3 trillion figure reflects avoided vehicle‑technology and charger costs and does not account for any health or environmental benefits that the standards might have provided. Nonetheless, the EPA’s calculations focus on direct compliance expenses, which are a tangible measure of the economic impact of federal regulation.
Overall, the agency’s report frames the Trump administration’s deregulatory agenda as a significant fiscal relief for American industry and consumers, aligning with the administration’s broader goal of cutting red tape and fostering economic growth.
