• U.S. Chamber Letter to DOT, EPA, and CARB on Achievable, Nationwide Fuel Economy Standards

August 29, 2019

Dear Secretary Chao, Administrator Wheeler, and Chair Nichols: The U.S. Chamber of Commerce urges you to redouble efforts to identify a workable path forward on light duty vehicle fuel economy and greenhouse gas standards that provides regulatory certainty, continues progress on mileage and emissions reductions, and preserves a unified national program for vehicle sales.

This framework, known as One National Program, or ONP, has allowed for efficient regulatory compliance and a smoothly functioning marketplace under which manufacturers can sell the same vehicles across all 50 states. This significantly reduces vehicle design, supply chain, and distribution costs. As you know, however, ONP is now on the brink of potential dissolution into a patchwork of incompatible state and federal standards.
