Climate change is real and automakers believe we have a responsibility to reduce carbon emissions from our products. Carbon is emitted from burning fuel, so greater fuel efficiency and alternative powertrains are two approaches to reduce carbon emissions.
Automakers have increased fuel efficiency across all classes of vehicles, giving consumers more choice in vehicles that deliver higher MPG. Automakers are also investing substantially in alternative powertrains, offering more than 50 models of plug-in electric and fuel cell electric vehicles, as well as more than 40 models of hybrid-electric models. More electrified models are on the way to market. We urge consumers to consider buying one when car-shopping for their next vehicle.
The auto sector has already made significant carbon reductions in its products. Fleet-wide automobile carbon dioxide (CO2) reductions are already more than 21 percent lower than in 2005. According to the 2017 EPA Trends Report, the real-world emissions of new cars and light trucks went from an average of 447 g/mi CO2 in 2005 to 352 g/mi in 2017 (preliminary).
Carbon dioxide reductions by the auto sector already approach the Paris goals for 2025. Under the Paris Climate Accord, the Obama Administration agreed that by 2025 the U.S. would cut greenhouse emissions by 26-28 percent compared to 2005 levels. In addition, automakers are working to reduce carbon emissions in their facilities as well.
