Hey Congress—Don’t Let Automakers Undercut Fuel Standards with Phony Credits!

Whether it’s the Volkswagen debacle (which continues to get worse), the massive Takata airbag recall involving just about every car company on the planet, or the GM ignition switch scandal, automakers have been in the news recently for all the wrong reasons. So it was no surprise when the Energy and Commerce Committee of the U.S. House of Representatives recently held a hearing on draft legislation regarding vehicles and roadway safety. After all, Congress should hold deceitful automakers accountable for their actions, and they should help ensure access to safe, clean vehicles.

I’m sorry to inform you, but according to the EPA your car has been polluting the environment at a level between 10 and 40 times its legal limit. Volkswagen and Audi, who manufacture the majority of diesel vehicles in the United States, have been cheating emissions tests instead of complying with more stringent smog-forming pollution standards.

Fleet Experts Weigh In: Fuel Economy Rules for Trucks Pay Off

With fuel such a key expense for truck fleets, one of the questions I get asked the most is—why do we need fuel economy rules? As I outlined in Engines for Change, there are actually a lot of market barriers that can slow investment in efficient trucking, including fuel surcharges and the risk-averse conservatism of a capital-constrained marketplace. But you don’t need to take my word for it: Fleet owners across the country also support fuel economy regulations. Read more >
