Mack Trucks has announced that its full lineup of model-year 2014 trucks and tractors is certified by the U.S. Environmental Protection Agency and National Highway Traffic Safety Administration as meeting 2014 fuel efficiency and greenhouse gas (GHG) regulations.

“Certification of Mack’s entire vehicle portfolio reflects our continued commitment to fuel efficiency, environmental stewardship, and the country’s long-term energy security,” said John Walsh, Mack vice president of marketing. 

Under the GHG14 regulations, trucks and buses built in 2014 through 2018 are projected to reduce oil consumption by 530 million barrels and greenhouse gas emissions by 270 million metric tons.
