The U.S. EPA rated the Volt's tailpipe emissions at 84 grams of carbon dioxide per mile (52.5 CO2 g/km). Charging the Volt's batteries still results in some greenhouse gas emissions from electrical generation at the local power station. However, under most conditions CO2 output is less than other low emission vehicles and in the best case emissions are nearly zero. GM claims that the Volt saves 4.4 metric tons in CO2 emissions annually compared to a typical U.S. car.

UK based Auto Express magazine claims in a non-scientific study to have calculated that the generation of electricity for charging the batteries in the Volt resulted in emissions equivalent to 124.2 g/km of CO2 for electric-only trips (those not involving the use of any on board fuel), based on government figures for the average CO2 emissions from power stations. According to Auto Express, this is more CO2 than the BMW 118d produces. Using CO2 emissions data for the United States, the Auto Express estimate can be shown to imply Volt's plug-to-wheel efficiency of approximately 340 Wh/mile - somewhat high for electric vehicles (Tesla Roadster is EPA rated at 280 Wh/mile plug-to wheel), but within the realm of possibility.
