US EPA, DOT Cleaner Heavy-Duty Trucks Proposal Commended by NGVAmerica
The U.S. Environmental Protection Agency (EPA) and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) are jointly proposing 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 proposal “Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles—Phase 2 has received commendation from NGVAmerica, the national association for the promotion of natural gas as a vehicle fuel.
“Today’s proposal has the potential to be a win-win-win that will lower greenhouse gas emissions, reduce fuel costs and reduce our nation’s dependence on foreign oil,” said Matthew Godlewski, President of NGVAmerica.
“Under the Phase 1 rule, natural gas trucks and buses are already delivering lower fuel costs and reduced emissions to fleet operators and consumers nationwide,” Godlewski continued. “We have appreciated the administration’s collaborative effort in developing this proposal. We look forward to working with EPA, NHTSA and the administration to finalize a Phase 2 rule that will create new opportunities for fleets to use natural gas to further reduce fuel costs and emissions, while increasing energy security.”
The proposed standards are expected to lower CO2 emissions by approximately 1 billion metric tons, cut fuel costs by about $170 billion, and reduce oil consumption by up to 1.8 billion barrels over the lifetime of the vehicles sold under the program. These reductions are nearly equal to the greenhouse gas (GHG) emissions associated with energy use by all U.S. residences in one year. The total oil savings under the program would be greater than a year’s worth of U.S. imports from the Organization of the Petroleum Exporting Countries (OPEC).
“Once upon a time, to be pro-environment you had to be anti-big-vehicles. This rule will change that,” said U.S Transportation Secretary Anthony Foxx. “In fact, these efficiency standards are good for the environment – and the economy. When trucks use less fuel, shipping costs go down. It’s good news all around, especially for anyone with an online shopping habit.”
The proposed standards are cost effective for consumers and businesses, delivering favorable payback periods for truck owners; the buyer of a new long-haul truck in 2027 would recoup the investment in fuel-efficient technology in less than two years through fuel savings.
“We’re delivering big time on President Obama’s call to cut carbon pollution,” said EPA Administrator Gina McCarthy. “With emission reductions weighing in at 1 billion tons, this proposal will save consumers, businesses and truck owners money; and at the same time spur technology innovation and job-growth, while protecting Americans’ health and our environment over the long haul.”
Medium- and heavy-duty vehicles currently account for about 20 percent of GHG emissions and oil use in the U.S. transportation sector, but only comprise about five percent of vehicles on the road. Globally, oil consumption and GHG emissions from heavy-duty vehicles are expected to surpass that of passenger vehicles by 2030. Through the G-20 and discussions with other countries, the United States is working with other major economies to encourage progress on fuel economy standards in other countries, which will improve global energy and climate security by reducing reliance on oil.
The product of three years of extensive testing and research, the proposed vehicle and engine performance standards would cover model years 2021-2027, and apply to semi-trucks, large pickup trucks and vans, and all types and sizes of buses and work trucks. They would achieve up to 24 percent lower CO2 emissions and fuel consumption than an equivalent tractor in 2018, based on the fully phased-in standards for the tractor alone in a tractor-trailer vehicle.
The proposal includes separate engine standards that will promote continued progress on engine efficiency and allow for direct measurement of engine emissions.
Today’s proposal builds on the fuel efficiency and GHG emissions standards already in place for model years 2014-2018, which alone will result in emissions reductions of 270 million metric tons and save vehicle owners more than $50 billion in fuel costs. The current standards have been successful, with truck sales up in model years 2014 and 2015 due in part to improved fuel efficiency.
A public comment period will be open for 60 days after the proposal is published in the Federal Register. For more details on DOT’s and EPA’s notice of proposed rulemaking, visit www.epa.gov/otaq/climate/regs-heavy-duty.htm andwww.nhtsa.gov/fuel-economy.
