Fuel is expensive, and big trucks use a lot of it as they travel America’s highways. But that doesn’t mean the trucking industry is completely in favor of the higher fuel-efficiency standards proposed by the Obama administration. Industry groups say they could come with some negative side effects. More details:

About the standards: This week, President Obama announced that the Department of Transportation and Environmental Protection Agency would begin to develop a set of fuel-efficiency standards for medium- and heavy-duty trucks for model year 2019 and beyond (rules for model years 2014 to 2018 were implemented in 2011). “For the first time in nearly 20 years, America produces more oil here at home than we buy from other countries. Our levels of dangerous carbon pollution, that contributes to climate change, have actually gone down even as our production has gone up,” the president said in an announcement on Tuesday, according to CNN. Major truck manufacturers, such as Cummins, told the Wall Street Journal that they’ve already been working closely with the U.S. Department of Energy on the issue and that the changes to their processes would not be radical. But discussions on the new standards are ongoing, and Obama offered no specifics in his speech.

Proceed with caution: In the wake of the president’s announcement, Bill Graves, president of the American Trucking Association, said in a statement that the idea makes sense in theory, but he warned that rushing the rules could lead to problems. ATA told The Washington Post that the administration will give it a voice in creating the new standards. “Fuel is one of our industry’s largest expenses, so it makes sense that as an industry we would support proposals to use less of it,” Graves said. “However, we should make sure that new rules don’t conflict with safety or other environmental regulations, nor should they force specific types of technology onto the market before they are fully tested and ready.” The Owner-Operator Independent Drivers Association echoed the sentiment in a statement of its own, noting the pressure that additional costs could put on independent drivers.

Full speed ahead: The eco-friendly Natural Resources Defense Council welcomed the announcement, noting that, like prior energy-efficiency programs in the auto industry, the effort could create new jobs. “The president’s initiative is an important step driving America toward a cleaner energy future,” NRDC President Frances Beinecke said in a statement. “Strong heavy-truck efficiency standards will not only cut carbon pollution that fuels climate change, but also save consumers money every time they go to a store and save truckers money at the pump.” In a statement to The Post, the National Association of Clean Air Agencies, which backs the move, noted the industry’s cooperative approach.
