evidence: Other recent studies of electric cars in Germany have reached the opposite conclusion. One study found that emissions from EVs have emissions up to 43% lower than diesel vehicles. Another detailed that "in all cases examined, electric cars have lower lifetime climate impacts than those with internal combustion engines". [...] The general premise that EVs are not currently a panacea for climate change and that the life cycle greenhouse gas emissions from electric vehicles can be similar to or even greater than the most efficient gasoline or diesel vehicles is supported by other research, including the work of my group over the past decade. But it’s important to note that which technology comes out on top depends on a lot of things, especially: [...] Studies that compare EVs (which are mostly smaller cars) to an average gasoline or diesel vehicle (much larger) and assign the average grid mix in an area to the electric vehicle tend to have favorable findings for EVs. Studies that compare EVs to comparable gasoline or diesel vehicles and examine the consequential emissions (how the grid will change in response to buying an EV vs. a gasoline/diesel vehicle) tend to have findings that are more mixed. I would put more weight on the second type of study and put more weight on peer-reviewed academic studies than on studies by advocacy groups or consulting groups that are not fully transparent.
