EPA Sets Stricter Heavy-Duty Vehicle Emission Standards Through 2032, Drawing Industry Concerns Over Feasibility

• EPA announced new emissions standards for heavy-duty vehicles for model years 2027-2032, aiming to avoid 1 billion tons of greenhouse gas emissions

• Standards are performance-based and technology-neutral; manufacturers can use different technologies like advanced engines, hybrids, EVs to meet requirements

• Standards will gradually increase emissions reductions required each year over the period

• Administration touts climate, health, and economic benefits, but trucking industry objects that later targets are unrealistic

• Rules continue administration's push for climate action, following recent light-duty vehicle standards
