So, EVs that are built with batteries from existing factories are going to have large carbon footprints.īut that's changing, he said, as 'people have realized that's a huge carbon footprint.'Įxperts pointed to other considerations around battery production. Department of Energy's Joint Center for Energy Storage Research, told CNBC, adding that the energy source used in battery production makes a huge difference on the carbon footprint for EVs.īatteries made in older gigafactories in China are usually powered by fossil fuels, because that was the trend five to 10 years ago, he explained. 'I think the battery is the most complicated component in the EV, and has the most complex supply chain,' George Crabtree, director of the U.S. Batteries are the biggest emitterĬhina currently dominates battery production, with 93 gigafactories producing lithium-ion battery cells versus only four in the U.S., the Washington Post reported this year.

'When you look forward to the rest of the decade, where we will see massive amounts of decarbonization in power generation and massive amount of decarbonization in the industrial sector, EVs will benefit from all of that decarbonization,' Eric Hannon, a Frankfurt-based partner at McKinsey & Company, told CNBC. Efforts to cut down pollution across various industries are expected to further reduce the environmental impact of EV production and charging over time. In 2050, their projected emissions are expected to be between 160 to 205 grams of CO2 per mile - the range is wider than EVs, because fuel standards vary from place to place.ĭecarbonization is the process of reducing greenhouse gas emission produced by the burning fossil fuels. Similarly, Paltsev said MIT research showed non-plug-in hybrid cars with internal combustion engines currently emit about 275 grams of CO2 per mile. 'We are projecting that with cleaning up the grid, we can reduce emissions from electric vehicles by 75%, from about 200 (grams) today to about 50 grams of CO2 per mile in 2050.' 'Currently, the electric vehicle in the U.S., on average, would emit about 200 grams of CO2 per mile,' he said. Personal Loans for 670 Credit Score or Lower
