→ Reconsideration of the greenhouse gas emissions standards for Model Year 2022-2025 light-duty vehicles; Request for comment on Model Year 2021 standards

Comments Close:

The Environmental Protection Agency is reconsidering whether the greenhouse gas emissions standards for model year 2022-2025 light-duty vehicles, produced in a January 2017 Mid-Term Evaluation Final Determination, 'are appropriate under section 202(a) of the Clean Air Act and invites stakeholders to submit any comments, data, and information they believe are relevant to the Administrator's reconsideration and in particular, highlight any new information.' Per a March 2017 notice, the Environmental Protection Agency plans to coordinate its reconsideration with the parallel rulemaking by the Department of Transportation's National Highway Traffic Safety Administration 'regarding Corporate Average Fuel Economy standards for cars and light trucks for the same model years.' The Environmental Protection Agency 'intends to make a Final Determination regarding the appropriateness of the model year 2022-2025 standards no later than April 1, 2018.' In this document, EPA is also requesting comment on the separate question of whether the light-duty vehicle greenhouse gas standards established for model year 2021 remain appropriate.'
