Carbon Footprint of New Light Vehicles Drops Between 1975 and 2007
The carbon footprint is a measure of greenhouse gas emissions produced by cars which is closely tied to fuel economy. As fuel efficiencies have increased for each size class, the carbon footprint for that class has decreased a proportional amount. Overall, both cars and trucks have experienced a decrease in annual greenhouse gas emissions of about 43% between 1975 and 2007. Within the car classes, midsize cars experienced the greatest improvement with a decrease in annual greenhouse gas emissions of 52%. Among the truck classes, midsize SUVs had the largest decrease with 47.8%. Of all vehicle classes, midsized pickup trucks reduced greenhouse gas emissions the least with a decrease of only 4.8 percent.
* Annual CO2 Emissions are based on 55% City Driving and 45% Highway and 15,000 miles of annual driving.
** No small vans or small pickups were offered in the 2007 model year.
