EPA Sets Stricter Emissions Rules for Trucks and Buses, Aiming to Cut Pollution and Boost Zero-Emission Vehicles

EPA sets new emissions standards for heavy-duty trucks, buses, and other large vehicles through 2032 to reduce greenhouse gases by 1 billion tons over 30 years.

Standards aim to benefit 72 million Americans living near freight routes with cleaner air.

Rules require increasing percentages of zero-emission vehicles like electric and hydrogen-powered trucks and buses.

Trucking industry groups argue standards are unachievable with current technology and could disrupt supply chains.

EPA says standards give choices for powertrains and will save truck owners $3.5 billion in fuel costs while paying for new vehicles within 2-4 years.
