On March 20, 2024, the U.S. Environmental Protection Agency (EPA) announced final national pollution standards for passenger cars, light-duty trucks, and medium-duty vehicles for model years 2027 though 2032 and beyond. The final standards, “Multi Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium-Duty Vehicles,” consist of several key elements including more stringent emission standards for greenhouse gas emissions (GHGs), more stringent emission standards for criteria pollutants such as PM2.5, NOx, and VOC, and other improvements to existing light-duty and medium-duty programs. The standards will continue the technology-neutral and performance-based approach of previous EPA standards for cars, pickup trucks, and vans, and will leverage advances in clean car technologies to further reduce GHGs and other harmful air pollutants. The standards are also estimated to avoid seven billion tons of carbon emissions through 2055, provide roughly $100 billion of annual net benefits, including $13 billion of annual public health benefits due to improved air quality, and $62 billion in reduced annual fuel and maintenance costs for drivers.
