Proposed Determination on the Appropriateness of the Model Year 2022-2025 Light-Duty Vehicle Greenhouse Gas Emissions Standards Under the Midterm Evaluation

Résumé

On or about November 30, 2016, the Environmental Protection Agency (EPA) made available for public comment its proposed adjudicatory determination that the GHG standards currently in place for MY2022-2025 remain appropriate under the Clean Air Act and therefore should not be amended to be either more or less stringent. EPA made this Proposed Determination as part of its Midterm Evaluation of light-duty vehicle greenhouse gas (GHG) emissions standards for model years (MY) 2022-2025, as required under its regulations. The Proposed Determination follows a Draft Technical Assessment Report (TAR) issued jointly by EPA, the National Highway Traffic Safety Administration (NHTSA), and the California Air Resources Board (CARB) in July 2016. In the Draft TAR, the agencies examined a wide range of issues relevant to the appropriateness of the GHG emissions standards for MY2022-2025, and shared with the public its initial technical analyses of those issues. The Draft TAR was required by EPA's regulations as the first step in the Midterm Evaluation process. For the next step, the Proposed Determination, EPA has considered public comments submitted on the Draft TAR as well as other information,
