Tesla Challenges U.S. EPA’s Rollback of Vehicle Emission Standards

Tesla (TSLA) has formally opposed the U.S. Environmental Protection Agency's proposal to repeal vehicle emissions standards, calling the plan 'highly disruptive and unlawful.' In a September 2025 comment letter, the electric vehicle manufacturer argued that the EPA failed to provide adequate legal or factual justification for dismantling regulations that hold automakers accountable for greenhouse gas emissions.

The move comes as part of the TRUMP administration's broader campaign to unwind climate-focused regulations. Tesla warned that scrapping the standards would retroactively exempt manufacturers from measuring and reporting emissions—a critical tool for mitigating environmental impact. The 2009 EPA finding on the dangers of greenhouse gases remains a cornerstone of Tesla's argument.
