EPA Finalizes Tailpipe Emissions Rules to Halve Carbon Pollution by 2032

The new regulations aim to significantly reduce vehicle emissions, encouraging a shift towards electric vehicles and supporting union jobs in the auto sector.

The EPA's new tailpipe emissions rules for cars built from 2027 through 2032 aim to cut carbon dioxide emissions from passenger cars by nearly 50% in model year 2032.
The rules are expected to increase the sale of electric vehicles (EVs), with projections suggesting up to 56% of new cars could be EVs by the 2030-2032 model years.
The regulations also support American labor, potentially boosting union jobs in the auto sector, particularly at plants like the Volkswagen facility in Chattanooga, Tennessee.
Explicit requirements for monitoring and ensuring the durability of EV batteries are introduced for the first time, aiming to standardize battery health and longevity.
Adjustments in the utility factor for plug-in hybrids reflect a more accurate representation of their contribution to reducing emissions, encouraging manufacturers to prioritize more efficient vehicles.
