Major improvements with emissions

You’ll notice that the emissions of CO2 from GM cars and light trucks have significantly decreased since the mid-1970's. This is because the fuel efficiency in their vehicles has increased. This is a great thing for both the vehicle and for our environment.

 

Since the mid-1960’s, vehicle tailpipe emissions of hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) have decreased. In both the United States and Canada, HC, CO, and NOx of passenger cars have decreased by 99%, 96%, and 95%, respectively.

 

Choose the right vehicle for you

The CO2 emissions from GM cars and light trucks in both the United States and Canada have remained at a consistent level since 1990. Consumers have chosen larger vehicles with more features and bigger engines, offsetting much of our fuel economy gains.

GM works hard to keep emissions low
