ACEEE Testimony on EPA and NHTSA’s Proposed GHG and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles

The adoption of fuel efficiency and greenhouse gas standards for medium- and heavy-duty vehicles is a major step toward managing the nation’s oil consumption, emissions, and fuel expenditures, and by extension the cost of consumer goods. It also offers the potential of new jobs in the design and production of new vehicle technologies. Domestic manufacturers and suppliers are leaders in certain advanced truck technologies, and this program has the potential to help them consolidate their leadership and thrive in a global market. At the same time, those interested in truck fuel efficiency across the world are watching this rulemaking as other governments develop their own programs to improve truck efficiency and cut GHG emissions. The final rule can set the stage globally in this regard.
