SUPPLEMENTARY INFORMATION:

Under its Clean Air Act section 202 authority, the Environmental Protection Agency (EPA) is proposing new, more stringent emissions standards for criteria pollutants and greenhouse gases (GHG) for light-duty vehicles and Class 2b and 3 (“medium-duty”) vehicles that would phase-in over model years 2027 through 2032. In addition, EPA is proposing GHG program revisions in several areas, including off-cycle and air conditioning credits, the treatment of upstream emissions associated with zero-emission vehicles and plug-in hybrid electric vehicles in compliance calculations, and vehicle certification and compliance. EPA is also proposing new standards to control refueling emissions from incomplete medium-duty vehicles, and battery durability and warranty requirements for light-duty and medium-duty plug-in vehicles. EPA is also proposing minor amendments to update program requirements related to aftermarket fuel conversions, importing vehicles and engines, evaporative emission test procedures, and test fuel specifications for measuring fuel economy. The “Multi-Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium-Duty Vehicles” proposed rule was signed on April 11, 2023 and will be published in the Federal Register . The pre-publication version is available at https://www.epa.gov/​regulations-emissions-vehicles-and-engines/​proposed-rule-multi-pollutant-emissions-standards-model.

EPA is hosting a separate hearing for the “Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles—Phase 3” (HDP3) proposed rule that was signed on April 11, 2023.
