Biden reverses Trump’s rollback of mileage rules

New fuel standards for 2023 models designed to curb vehicle tailpipe emissions

WASHINGTON — In a major step to fight climate change, the Biden administration is raising vehicle mileage standards to significantly reduce emissions of planet-warming greenhouse gases, reversing a Trump-era rollback that loosened fuel efficiency standards.

A final rule issued Monday would raise mileage standards starting in the 2023 model year, reaching a projected industrywide target of 40 miles per gallon by 2026. The new standard is 25% higher than a rule finalized by the Trump administration last year and 5% higher than a proposal by the Environmental Protection Agency in August.

“We are setting robust and rigorous standards that will aggressively reduce the pollution that is harming people and our planet — and save families money at the same time,” EPA Administrator Michael Regan said. He called the rule “a giant step forward” in delivering on President Joe

Biden’s climate agenda “while paving the way toward an all-electric, zero-emissions transportation future.?

The move comes a day after Democratic Sen. Joe Manchin delivered a potentially fatal blow to Biden’s $2 trillion social and environmental policy bill, jeopardizing Democrats’ agenda.

The now-stalled bill includes a $7,500 tax credit to buyers to lower the cost of electric vehicles.

Regan said that even without the EV tax credits and other incentives, “we believe that we proposed a rule that is doable.”

The new mileage rules are the most ambitious tailpipe pollution standards ever set for passenger cars and light trucks. The standards raise mileage goals set by the Trump administration that would achieve only 32 miles per gallon in 2026. Biden had set a goal of 38 mpg in August.

The standards also will help expand the market share of zero emissions vehicles, the administration said, with a goal of battery electric and plug-in hybrid vehicles reaching 17% of new vehicles sold in 2026. EVS and plug-in hybrids are expected to have about 7% market share in 2023.

The EPA said the rule would not only slow climate change, but also improve public health by reducing air pollution and lower costs for drivers through improved fuel efficiency.

Biden has set a goal of cutting U.S. greenhouse gas emissions by at least half by 2030 as he pushes a history-making shift in the U.S. from internal combustion engines to battery-powered vehicles.

He has urged that components needed to make that sweeping change — from batteries to semiconductors — be made in the United States, too, aiming for both industry and union support for the environmental effort, with the promise of new jobs and billions in federal electric vehicle investments.

The new standards provide adequate time for auto manufacturers to comply at reasonable costs, the administration said. EPA’S analysis shows the industry can comply with the standards with modest increases in the numbers of EVS.
