GM Works Hard to Reduce Emissions
The emissions of CO2 from GM cars and light trucks have decreased significantly since the mid-1970s as fuel efficiency has increased. Since the mid-1960s, vehicle tailpipe emissions of hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) have significantly decreased. In the United States and Canada, HC, CO and NOx of passenger cars have decreased by 99 percent, 96 percent, and 95 percent, respectively. Since 1990, CO2 emissions from GM cars and light trucks in the U.S. and Canada have been relatively constant, as consumers have chosen larger vehicles with more features and more powerful engines, offsetting much of our fuel economy gains. | READ MORE |
