When we talk about the environmental benefits of electric vehicles (EVs), we get a lot of questions about the lifetime greenhouse gas (GHG) impact of EVs vs internal combustion engine (ICE) cars. Electric cars don’t have tailpipe emissions when running on electricity, but battery manufacturing is an energy-intensive process. So how does the math work out? According to this report from the Union of Concerned Scientists (UCS), EVs have far fewer global warming emissions over their lifetime than ICE cars. Inthis blog, we'll break down the research from UCS and explain how EVs are cleaner and produce less total GHG emissions.
