Scientists’ Statement to Strengthen the U.S. Environmental Protection Agency’s Proposed Rules: Greenhouse Gas Emissions Standards for Heavy-Duty Engines and Vehicles-Phase 3 (Docket ID No. EPA-HQ-OAR-2022-0985) and Multi-Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium-Duty Vehicles (Docket ID No. EPA-HQ-OAR-2022-0829)

A statement signed by over 1,000 experts calling on the U.S. EPA to implement the strongest possible emissions standards for light-, medium-, and heavy-duty vehicles. The signatories argue that zero-emission vehicles are currently available and that the EPA should mandate 100% electric new vehicle sales by 2035 to protect public health and address the climate crisis, particularly in environmental justice communities.

• The transportation sector is the primary source of global warming emissions in the United States. Heavy-duty trucks, while representing only 10% of vehicles on the road, are responsible for 28% of on-road global warming emissions, 45% of nitrogen oxide emissions, and 57% of particulate matter emissions.
• Vehicle pollution disproportionately impacts environmental justice communities, specifically those located near freight corridors and ports.
• The signatories argue that zero-emission vehicles are currently available and should be the primary priority for the EPA to protect public health and mitigate the climate crisis.
• The statement recommends that the EPA ensure 100% of all new vehicle sales are electric by 2035 to maximize clean air.
• Existing state standards in several U.S. states are projected to result in electric vehicles making up more than 50% of new heavy-duty vehicle sales by 2030.
