The Obama administration has approved a rule setting stricter goals for medium- and heavy-duty truck fuel consumption and carbon emissions, phased in through 2027.
The final rule, which the Environmental Protection Agency Administrator Gina McCarthy and Dept. of Transportation Secretary Anthony Foxx signed on Aug. 16, will reduce carbon emissions by 1.1 billion tons and save truck operators an estimated $170 billion in motor-fuel expenses, the White House says.
