The U.S. Environmental Protection Agency (EPA) in April of this year announced proposed regulations to tighten restrictions on tailpipe emissions for light and medium-duty vehicles and greenhouse gas emissions from heavy-duty vehicles beginning with the 2027 model year.
In order to meet the new requirements, the proposed regulations could effectively require automakers to produce zero-emission vehicles that would conservatively account for at least 40% of their annual sales by 2030.
Questions remain about the requirements set forth in the proposed regulations, whether the requirements are technologically achievable, and at what cost to the economy, industry, and society at large. Comments to the heavy-duty rule were due June 16, 2023, and comments to the light and medium-duty rule were due July 5, 2023.
