A new report shows that the GMC Hummer EV produces more CO2 per mile driven than some gas-powered vehicles.
The research shows that the over 9,000-pound Hummer EV produces around 341 grams of CO2 per mile driven.
That compares to a gas-powered Chevy Malibu which emits around 320 grams of CO2.
Although the Hummer EV does not give off emissions, the CO2 numbers come from the average US power grid consumption.
The Hummer EV is not a very efficient vehicle, and when combined with the inefficient US power grid, it is not a recipe for success.
Sixty per cent of US energy comes from burning fossil fuels, which means that even when using an electric car, you are still dealing with a carbon footprint.
However, the research also shows that most electric vehicles have a much smaller carbon footprint than gas vehicles.
For instance, the Chevy Bolt is responsible for 92 grams of CO2 per mile driven.
So, not only do automakers need to consider the efficiency of their cars, governments need to consider where the power is coming from to make positive and meaningful impacts on CO2 emissions.
