Proposed Rulemaking: Phase 2 Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles

The U.S. Environmental Protection Agency (EPA) and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) are jointly proposing a national program that would establish the next phase of greenhouse gas (GHG) emissions and fuel efficiency standards for medium- and heavy-duty vehicles. This “Phase 2 program” would significantly reduce carbon emissions and improve the fuel efficiency of heavy-duty vehicles, helping to address the challenges of global climate change and energy security.

Information on Public Hearings:
EPA and NHTSA will jointly hold a public hearing in Chicago, IL on Thursday, August 6, 2015, beginning at 9:00 am local time, and a second hearing in Long Beach, CA on Tuesday, August 18, 2015, beginning at 9:00 am local time.

    Call-in information for August 6 and August 18 hearings:

  • Toll-free dial in: (877) 396-8104 (for international callers: (720) 362-6938).
  • Passcode: 29834687, then "#".

  • Please note that the conference line will be in 'listen-only' mode.

    Tractor-Trailer Parking for the Long Beach, California Public Hearing
    Parking for tractor-trailers will not be available at the Westin Hotel. However, parking for up to ten tractor-trailers is available nearby at the Long Beach Convention and Entertainment Center (562-436-3636). The parking lot is located on E. Seaside Way near the intersection with Linden Avenue (south of Ocean Boulevard), and is open from 7:00 am until 8:00 pm. Parking for a tractor-trailer is estimated to cost $40 for a half day.

Extending the Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles

EPA and NHTSA, in collaboration with the California ARB, plan to extend the Heavy-Duty National Program beyond model year 2018, to further reduce fuel consumption through the application of advanced cost-effective technologies and continue efforts to improve the efficiency of moving goods across the United States.

The complementary EPA and NHTSA standards that make up the Heavy-Duty National Program apply to combination tractors (semi trucks), heavy-duty pickup trucks and vans, and vocational vehicles (including buses and refuse or utility trucks). Together, these standards will cut greenhouse gas emissions and domestic oil use significantly. This program responds to President Obama’s 2010 request to jointly establish greenhouse gas emissions and fuel efficiency standards for the medium- and heavy-duty highway vehicle sector.
