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.

EPA is evaluating the impact of this rule on small entities. Small businesses, governments, and not-for-profit organizations that may be subject to the rule requirements can self-nominate by April 16, 2014 to participate in this process.
