Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time.
The decrease was driven by the economic downturn, combined with a significant switch from coal to natural gas as a source of electricity generation, according to the EIA. The EIA projects that fuel switching in the electric power sector and declines in industrial use will lead to a 7.9% Natural Gas.
