[no-glossary]Heavy-duty vehicles consume 2.9 million barrels per day of petroleum fuels in the United States today. In 2011, the National Highway Traffic Safety Administration and the Environmental Protection Agency adopted standards to reduce the fuel consumption and greenhouse gas emissions of heavy-duty vehicles in model years 2014–2018.
With heavy truck fuel efficiency standards in place and federal agencies gearing up for the next phase of the program, it’s time to consider energy savings opportunities in the freight system more broadly. Our new report Energy Efficiency Potential of the U.S.
Freight movement is among the fastest growing energy uses in the world, yet fuel efficiency and greenhouse gas emissions standards for the heavy-duty vehicles that move freight are still in their infancy.

Washington, D.C.—With aggressive national fuel economy standards kicking in for model years 2012 to 2025, automakers have provided consumers with an impressive array of efficient vehicle options for 2013 according to new environmental automotive ratings released today. The American Council for an Energy-Efficient Economy’s 15th annual comprehensive environmental ratings can be found at greenercars.org.
A comprehensive approach to transportation energy efficiency must include a combination of strategies targeted at both vehicle fuel efficiency and travel behavior. While the federal government has taken the lead on fuel efficiency, local and regional policies that reduce the need for driving are also essential to achieve an efficient and sustainable transportation system.
Washington, D.C.—The U.S. EPA recently found that auto manufacturers Hyundai and Kia had overstated the fuel economy of several of their vehicles in model years 2011, 2012, and 2013. EPA has released updated fuel economy label values for these vehicles. As a result, ACEEE has adjusted Green Book ratings for model years 2011 and 2012.
The Department of Transportation and the Environmental Protection Agency today finalized federal car and light truck fuel economy and greenhouse gas emissions standards for model years 2017 to 2025. The standards, together with those previously adopted for model years 2012 to 2016, mean an 80 percent increase in fuel economy for the average model year 2025 vehicle from the 2011 CAFE (Corporate Average Fuel Economy) requirement of 27.6 miles per gallon.
As the energy efficiency of products, homes, and businesses improves, it becomes less expensive to operate them. The rebound effect postulates that people increase their use of products and facilities as a result of this reduction in operating costs, thereby reducing the energy savings achieved. Periodically, some analysts raise questions about the rebound effect, arguing that it is a major factor that needs to be accounted for when analyzing energy efficiency programs.
