Abstract

EPA and NHTSA, on behalf of the Department of Transportation, are each proposing rules to establish a comprehensive Heavy-Duty National Program (Phase II) that will reduce greenhouse gas emissions and fuel consumption for onroad heavy-duty vehicles, responding to the President’s directive on March 31, 2014, to take coordinated steps to produce a new generation of clean vehicles. NHTSA’s proposed fuel consumption standards and EPA’s proposed carbon dioxide (CO2) emissions standards are tailored to each of three regulatory categories of heavy-duty vehicles: Combination Tractors; Heavyduty Pickup Trucks and Vans; and Vocational Vehicles. The rules include separate standards for the engines that power combination tractors and vocational vehicles. Certain rules are exclusive to the EPA program. These include EPA’s proposed hydrofluorocarbon standards to control leakage from air conditioning systems in combination tractors, and pickup trucks and vans. These also include EPA’s proposed nitrousoxide (N2O) and methane (CH4) emissions standards that apply to all heavy-duty engines, pickup trucks and vans.
