Washington—Senator Dianne Feinstein (D-Calif.) today released the following statement on the Trump administration’s refusal to negotiate with California to maintain a single national fuel economy program:

“The Trump administration’s announcement it won’t negotiate with California comes as no surprise. From the start, the administration has refused to work with California, choosing instead to upend the national fuel economy program.

“Prior to President Trump taking office, California worked with the federal government to maintain one national program for fuel economy and vehicle emission standards, which are set to rise to more than 50 mpg by 2025. The Trump administration now wants to tear up that common framework by attacking California’s legal right to reduce tailpipe pollution.

“There’s simply no good reason to upend the progress made under the single set of standards. Cars are emitting less pollution, families are saving more at the pump and auto manufacturers, which are meeting the standards at lower-than-expected costs, have the regulatory certainty they need to plan investments. In short, the system is working.

“Rather than inject more chaos in the marketplace, I encourage the Trump administration to make a good faith effort to work with California and help maintain a single national program for clean car standards.”


Senator Feinstein was the lead sponsor of the bipartisan Ten-in-Ten Fuel Economy Act passed in 2007. After joining with Senator Slade Gorton (R-Wash.) to fund a 2001 study that called for increasing fuel economy standards by more than 10 mpg, and partnering with Senator Olympia Snowe (R-Maine) to try to close the SUV loophole in 2003 and 2005, Senator Feinstein worked with Senators Snowe, Maria Cantwell (D-Wash.), Tom Carper (D-Del.) and others to introduce the Ten-in-Ten Fuel Economy Act.

Senators Daniel Inouye (D-Hawaii) and Ted Stevens (R-Alaska), chair and ranking member of the Senate Commerce Committee at the time, included the bill as part of a broader energy bill that was signed into law by President Bush in 2007. The bill requires the administration to set the maximum feasible fuel economy standards, which are currently scheduled to increase to more than 50 mpg by 2025.
