Shared by a family member. Hear out Dr Graham Conway, principal engineer in the Automotive Division at Southwest Research Institute, and why zero-emission vehicles are not truly zero-emission. It’s a point I’ve made way, way back (in the 2000s) when I cited a study which showed the Ford Fiesta Econetic, a diesel car, was the best vehicle for the environment over its lifetime.
This TEDx talk is from 2020, and Conway believes hybrids are a better bet for the environment than full EVs. Have a watch as he explains why.
TED has flagged Conway’s talk with the following statement: ‘This talk only reflects the speaker’s personal views and interpretation. Several claims in this talk lack scientific support.’ I’d be irresponsible if I didn’t quote this. It’s also worth having a read of this from 2021 and this from 2020. Here’s one more link from Green Car Reports in 2020, titled ‘Lifetime carbon emissions of electric cars are much lower than previously suggested’. All of these suggest that newer production processes and decarbonization may be helping EVs rank better when their lifetime (including production) emissions are counted.
