Final Rule for Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles

Rule Summary

EPA and NHTSA, on behalf of the Department of Transportation, are each finalizing rules to establish a comprehensive Heavy-Duty National Program that will reduce greenhouse gas emissions and fuel consumption for onroad heavy-duty vehicles, responding to the President’s directive on May 21, 2010, to take coordinated steps to produce a new generation of clean vehicles. NHTSA’s final fuel consumption standards and EPA’s final carbon dioxide (CO2) emissions standards are tailored to each of three regulatory categories of heavy-duty vehicles: Combination Tractors; Heavy-duty Pickup Trucks and Vans; and Vocational Vehicles.
