Title: Multi-Pollutant Emissions Standards for Model Years 2027 and
Later Light-Duty and Medium-Duty Vehicles
Description: Under
the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is establishing
new, more protective emissions standards for criteria pollutants and greenhouse
gases (GHG) for light-duty vehicles and Class 2b and 3
("medium-duty") vehicles that will phase-in over model years 2027
through 2032. In addition, EPA is finalizing 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, medium-duty vehicle incentive
multipliers, and vehicle certification and compliance. EPA is also establishing
new standards to control refueling emissions from incomplete medium-duty
vehicles, and battery durability and warranty requirements for light- duty and
medium-duty electric and plug-in hybrid electric vehicles. EPA is also
finalizing 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.
