OK, who knows how electric car emissions compare to, say, diesel in terms of CO2/km? I mean pure battery electric, not hybrid. Obviously you have to assume some generating mix to produce the electricity, and the answer might vary for where you live: if you take France’s 70% nuclear electric then you get a different answer to our coal/oil/gas/electric mix.
But are there any decent numbers up anywhere?
[Update: the first commenter seems to have found the best ref, thanks. The answer is that EVs are a bit better but it does depend on what you're burning to make lectric.
Note: the Times on friday had an article claiming that the UK was making a big mistake by investing in more diesel trains rather than electrification, because in trains the diff is a factor of two -W]
