The rule will cut 1 billion tons of carbon dioxide by 2055, making it one of the Biden administration’s most significant climate regulations.

The Biden administration rolled out another rulemaking central to its climate agenda with a regulation slashing pollution from heavy-duty trucks.

The final version released Friday contains significant changes from the proposal — a revamp that parallels updates EPA made to its car rule earlier this month.

The truck rule will cut 1 billion tons of carbon dioxide by 2055, EPA said in a statement, making it one of the country’s most significant climate regulations. It doesn’t dictate that truck-makers adopt a particular type of engine, but instead it imposes declining limits on CO2 emissions from heavy-duty trucks from model year 2027 through 2032.


“In finalizing these emissions standards for heavy-duty vehicles like trucks and buses, EPA is significantly cutting pollution from the hardest working vehicles on the road,” EPA Administrator Michael Regan said.

Heavy-duty trucks make up 4 to 5 percent of vehicles on the road but are the second-biggest source of transportation pollution after passenger cars.

The rule is also projected to cut millions of tons of other pollutants, which predominantly affect vulnerable communities located near highways and shipping terminals.
