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.

For the next step, the Proposed Determination, EPA has considered public comments submitted on the Draft TAR as well as other information,
