On March 29, 2024, the U.S. Environmental Protection Agency (EPA) announced final national greenhouse gas pollution standards for heavy-duty vehicles, such as freight trucks and buses, for model years 2027 through 2032. The final standards, “Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles - Phase 3," build on EPA’s Heavy-Duty Phase 2 program from 2016 and maintain that program’s flexible structure, which is designed to reflect the diverse nature of the heavy-duty vehicle industry. The standards are technology-neutral and performance-based, allowing each manufacturer to choose what set of emissions control technologies is best suited for them and the needs of their customers. The standards will avoid 1 billion tons of greenhouse gas emissions and provide $13 billion in annualized net benefits to society related to public health, the climate, and savings for truck owners and operators. The final standards will also reduce dangerous air pollution, especially for the 72 million people in the United States who live near truck freight routes, bear the burden of higher levels of pollution, and are more likely to be people of color or come from low-income households.
