In a speech today 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 make up only 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 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 plug-in electric drive-trains, 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 $20,000 in fuel costs annually.
It is critical that the new standards developed by EPA and DOT are strong. Stringent standards will not only drive innovation for a wide range of new technologies, they will ensure that these technologies spread throughout the marketplace, instead of being found on only a small portion of vehicles.
Of course, setting new efficiency standards for medium- and heavy-duty vehicles is only one part of the solution to reduce carbon pollution and oil consumption. We must create an energy-efficient, multi-modal freight system that relies on trains and ships, as well as trucks. When we're smarter about what we ship and how we ship it, we save money and reduce carbon pollution.
President Obama's announcement of new heavy-duty vehicle standards will build upon a strong legacy of passenger-vehicle standards that is already reducing our oil consumption, including a transition to plug-in electric vehicles that run on little or no oil. While it will take EPA and DOT two years to develop new standards and incorporate input from the public, this is another tremendous opportunity to save drivers money at the pump and make our air cleaner to breathe. But most importantly, this is the kind of policy action that's good for manufacturers and businesses, good for workers and consumers, and a very real and significant step to addressing carbon pollution.
