President Obama Announces New Truck Efficiency Standards

Semi truckIn a speech recently in Maryland, President Obama directed his administration to move forward with standards to make our tractor trailers and commercial vehicles more efficient. Already the administration has set historic standards for passenger vehicles of 54.5 miles per gallon by 2025 that will cut U.S. carbon pollution nearly 10 percent. These truck standards are another step to slash oil use, save Americans money and bring down carbon pollution.

Medium and heavy-duty vehicles, everything from 18-wheelers to delivery trucks, are the fastest growing source of oil consumption in the transportation sector. Even though these vehicles only make up seven percent of the vehicles on the road, they guzzle more than 25 percent of transportation fuel. Although new fuel-saving technologies are found in some trucks, most 18-wheelers on the road average around six miles per gallon (mpg) — about the same as they did decades ago.

In 2010 the Environmental Protection Agency (EPA) and the Department of Transportation (DOT) finalized the first-ever efficiency standards for medium and heavy-duty vehicles sold from 2014-2018. These standards will ensure that new engines are more efficient, and will reduce fuel consumption in semi-trucks by roughly 20 percent.

Developing the next round of efficiency standards now will allow manufacturers to innovate and develop new fuel saving technologies, such as aerodynamic trailers, higher-efficiency engines, advanced materials and lower rolling resistance tires. Last year Peterbilt and Cummins showcased a 10-mpg truck as a part of the DOT’s Super Truck program. While 10-miles-per-gallon might not sound like much, it’s a big deal. By increasing fuel economy 54 percent over today’s average trucks, this prototype could slash greenhouse gas emissions and save an average driver $25,000 in fuel costs annually.
