Statement: Climate Mayors and C40 Cities Support Another Step Forward in Decarbonizing the Transportation Sector with the Finalization of EPA’s Light-Duty Vehicle Standards

March 20, 2024 – Today, on the road to a zero-emission transportation future, the Environmental Protection Agency (EPA) adopted a final rule for Multi-Pollutant Emissions Standards for Light-Duty and Medium-Duty Vehicles (LDV). We thank the EPA and the Biden Administration for this final rule and continuing to cut pollution from the transportation sector. Climate Mayors and C40 Cities look forward to continuing to work with the Administration to push for ambitious carbon reductions from transportation in cities while also providing low-cost mobility options and ensuring strong labor and job markets for residents.

The transportation sector accounts for 29% of GHG emissions nationally. This makes the transition to clean, zero-emission vehicles critical to achieving our climate and air quality goals —particularly for the wellbeing of low-income communities and communities of color who historically bear a disproportionate burden from harmful air pollution. EPA’s final standards will strengthen federal greenhouse gas (GHG) emissions standards for passenger cars, reducing air pollutants, helping residents save on fuel and maintenance costs, and improving public health.

Local leaders have long been at the center of delivering innovative solutions to lower transportation emissions in their cities. Last year, 66 U.S. mayors and other local officials sent a letter to EPA Administrator Regan urging more stringent standards for both Light-Duty and Heavy-Duty Vehicles. While these final LDV standards are vital to cutting pollution and cleaning up our air, more will need to be done to achieve our shared climate goals.

As we await a strong final rule on GHG Emissions Standards for Heavy-Duty Vehicles that many of our members called for in February, we are excited to see the final LDV standards and know cities will continue to lead on implementing smart and equitable climate solutions.

“The EPA standards are a step in the right direction toward achieving progress in the green transition and improving air quality in communities,” said Kate Wright, Climate Mayors’ Executive Director. “Many cities are taking ambitious steps toward decarbonizing our transportation systems, and with support from the Biden Administration, we can continue to build on crucial local momentum and deliver for generations to come.”

“Mayors across the United States are implementing exciting projects to cut transportation pollution, create jobs, and protect the health and safety of their residents,” said Kate Johnson, Head of US Federal Affairs at C40 Cities. “The EPA's new rule will accelerate the transition to clean, zero-emissions vehicles in every city, and provide critical national support for the local action that will create stronger and healthier communities for all.”
