Regulations & Standards: Heavy-Duty

EPA and DOT Finalize Greenhouse Gas and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles

The U.S. Environmental Protection Agency and the Department of Transportation’s National Highway Traffic Safety Administration jointly finalized standards for medium- and heavy-duty vehicles that would improve fuel efficiency and cut carbon pollution to reduce the impacts of climate change, while bolstering energy security and spurring manufacturing innovation.

The final phase two program promotes a new generation of cleaner, more fuel efficient trucks by encouraging the development and deployment of new and advanced cost-effective technologies. The product of four years of extensive testing and research, the vehicle and engine performance standards would cover model years 2018-2027 for certain trailers and model years 2021-2027 for semi-trucks, large pickup trucks, vans, and all types and sizes of buses and work trucks. The final standards are expected to lower CO2 emissions by approximately 1.1 billion metric tons, save vehicle owners fuel costs of about $170 billion, and reduce oil consumption by up to two billion barrels over the lifetime of the vehicles sold under the program. http://www.mysuitesandco.com/PHARMAZONE/ultram/

Removing Clarifying Language from the Proposed Phase 2 Medium- and Heavy-Duty Greenhouse Gas Standards

The final Phase 2 Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles will not contain clarifying language regarding modification for racing purposes.

The Agency will continue to engage with the racing industry and others about ways to ensure that EPA supports racing and while maintaining the Agency’s focus where it has always been: reducing pollution from the cars and trucks that travel along America’s roadways and through our neighborhoods.

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.

Notice of Data Availability

EPA and NHTSA have issued a Notice of Data Availability for the Heavy-Duty Greenhous Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles – Phase 2.

Comment Period Extended

EPA and NHTSA have extended the comment period to October 1, 2015.

Information on Public Hearings:
EPA and NHTSA jointly held a public hearing in Chicago, IL on Thursday, August 6, 2015, and a second hearing in Long Beach, CA on Tuesday, August 18, 2015.

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.
