EPA passes final emissions rule: Mayors and C40 Cities renew commitment to electrifying transportation in cities


April 2, 2024

On 29 March 2024, the Environmental Protection Agency (EPA) adopted a final rule for the GHG Emissions Standards for Heavy-Duty Vehicles - Phase 3 rule (HDV rule). The new standards will allow cities to accelerate the transition to zero-emission vehicles, eliminate harmful greenhouse gas emissions, improve air quality, and cut fuel and maintenance costs.

The final rule will reduce greenhouse gas emissions from heavy-duty vehicles - such as trucks and buses - in model year 2027 and apply new and more stringent standards for model years 2028 through 2032. The EPA's final standards for vehicles are critical for reducing CO2 emissions and are expected to reduce approximately 1 billion metric tonnes from 2027 through 2055 and deliver climate benefits at US$13 billion per year through the rule.

This heavy-duty vehicle rule complements the EPA's action to control air pollution from vehicles under its "National Freight Strategic Plan," which will support the transition to electrify our nation's heavy-duty fleets and reduce harmful pollution. By implementing this final rule, the EPA is driving the transition to zero-emission fleets of delivery trucks, school buses, and more in cities.

Mayors are committed to cutting emissions from the transportation sector and increasing the deployment of zero-emission vehicles. Transportation emissions account for nearly 30% of total U.S. carbon emissions with heavy-duty vehicles accounting for nearly 23% of transportation emissions. And while medium- and heavy-duty vehicles only account for a small portion of vehicles on U.S. roads, they generate the majority of harmful emissions. This rule will further bolster the Inflation Reduction Act (IRA) and Bipartisan Infrastructure Law (BIL) which support progress in zero-emission heavy-duty vehicle manufacturing, consumer adoption, and expansion of charging infrastructure.

By electrifying our vehicle fleets, we can impactfully deliver cleaner air and improved health outcomes in our cities - especially for disadvantaged communities who are disproportionately impacted by harmful pollution from heavy-duty trucks and buses.

"The EPA standards for heavy-duty vehicles will allow our cities to take critical action to decarbonize the transportation sector, provide cleaner air, and improve public health," said Kate Wright, Climate Mayors' Executive Director. "Our mayors will continue to strive to reach net zero goals as soon as possible in their cities and towns in order to tackle air pollution in our communities and reduce the rates of asthma and other respiratory illnesses. With these new standards, cities can continue to accelerate the transition to electric vehicles and meet our climate goals."

"Across the US, mayors are taking action to cut pollution from trucks in their cities to improve air quality, support economic development, and meet their climate goals," said Kate Johnson, Head of US Federal Affairs at C40 Cities. "The EPA's final rules for heavy-duty vehicles will help cities transition to cleaner vehicles, while delivering important health benefits to environmental justice communities by reducing air pollution along trucking routes. The sooner this transition happens, the better. Along with the powerful actions included in the IRA, BIL, and recent EPA rules on light duty vehicle emissions, the federal government is giving cities the tools to create a healthier, safer, and cleaner future for all."
