This directive applies to all models of motor vehicles produced from the model year 2022 and on, though it's specifically aimed at overhauling the 2024–2026 and 2027-and-beyond sets of CAFE ...
An emission performance standard is a limit that sets thresholds above which a different type of vehicle emissions control technology might be needed. While emission performance standards have been used to dictate limits for conventional pollutants such as oxides of nitrogen and oxides of sulphur (NO x and SO x ), [ 3 ] this regulatory ...

Reasons for banning the further sale of fossil fuel vehicles include: reducing health risks from pollution particulates, notably diesel PM10s, and other emissions, notably nitrogen oxides; [8] meeting national greenhouse gas, such as CO 2, targets under international agreements such as the Kyoto Protocol and the Paris Agreement; or energy independence.
The EPA's preferred standards would take carbon dioxide emissions from 186 grams per mile in 2026 to 82 in 2032, a 56% reduction. The limits would reach 111 grams per mile by 2029.
