DETROIT — General Motors pledged Thursday to double its number of models that get at least 40 miles per gallon on the highway by 2017 and said it would cut the emissions its U.S. vehicles produce 15% by 2016.
The efforts are part of GM's broader push to become a more environmentally sustainable company. The company surprised environmental groups earlier this year when it became the first automaker to sign a declaration asserting that going green is good for business.
The U.S. government also is nudging the automaker with its requirements that auto fleets average 54 mpg by 2025.
