EPA Scraps Key Greenhouse Gas Rules for Cars and Trucks
Published Date: 2/18/2026
Rule
Summary
The EPA is rolling back its 2009 decision that said greenhouse gases from cars and trucks are harmful and must be limited. This means new rules that cut emissions from all types of vehicles are being canceled because the EPA says it doesn’t have the legal power to regulate these gases under the Clean Air Act. This change affects car makers and could shift how we handle vehicle pollution starting April 20, 2026.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
Repeal of Vehicle GHG Standards
The EPA is repealing all greenhouse gas (GHG) emission standards for new light‑duty, medium‑duty, and heavy‑duty motor vehicles and engines manufactured or imported for model years 2012 through 2027 and beyond. This repeal takes effect April 20, 2026. The EPA states these GHG standards had imposed "trillions of dollars" in costs on manufacturers and American consumers.
Rescission of 2009 Endangerment Finding
The EPA is rescinding its 2009 "Endangerment Finding" that had concluded greenhouse gases from motor vehicles may be anticipated to endanger public health and welfare under Clean Air Act section 202(a)(1). The Agency says removing that finding eliminates the legal basis for prescribing GHG emission standards for new motor vehicles and engines under that provision, effective April 20, 2026.

2026-10085 — Rescission of Regulatory Determinations and Removal of Related Provisions for Four PFAS Substances (PFHxS, PFNA, HFPO-DA (GenX), and the Mixture of These Three PFAS Plus PFBS)
The EPA is proposing to undo its rules for four PFAS chemicals (PFHxS, PFNA, GenX, and a mix including PFBS) in drinking water because the original process wasn’t done right. This means public water systems won’t have to monitor or treat these chemicals for now. People and water providers should weigh in by July 20, 2026, and a virtual hearing happens July 7.
2026-10086 — Extending the Compliance Deadline for the PFOA and PFOS Maximum Contaminant Levels
The EPA is giving water systems more time to meet safety rules for two harmful chemicals, PFOA and PFOS, by extending the deadline from April 2029 to April 2031 if they ask for it. This helps water providers get ready without rushing, keeping our drinking water safe. The EPA wants your thoughts and will hold a public hearing in July 2026 to hear from everyone.

This change mainly affects businesses planning major construction and could speed up projects without extra costs, but comments are due by June 29, 2026.

The EPA has decided to cancel its plan to change the rules about what counts as hazardous waste for cleaning up pollution at certain waste sites. This means businesses and cleanup crews won’t have to deal with the confusing new rules that were proposed. The withdrawal takes effect immediately, so no extra costs or changes will happen right now.
2026-08750 — Extension of Postponement of Effectiveness for Certain Provisions of Trichloroethylene (TCE); Regulation Under the Toxic Substances Control Act (TSCA)
The EPA is hitting the pause button again on some rules about a chemical called TCE, which is used in workplaces. This means certain limited uses of TCE won’t have to follow new restrictions just yet, while courts review the rules. If you work with TCE, this delay gives you more time before changes kick in, starting May 18, 2026.

The EPA is giving businesses and workers a 90-day break by delaying some new rules about the chemical TCE until May 18, 2026. This extension affects certain uses of TCE that were supposed to face new restrictions starting February 17, 2026. It helps companies keep using TCE a bit longer while the EPA sorts out the details, so no sudden costs or changes hit just yet.
