Not according to the EPA [1]. In the US, transportation accounts for 28% of greenhouse emissions, and 82% of that (i.e. 23% of the total) from road vehicles [2]

Not according to the EPA [1]. In the US, transportation accounts for 28% of greenhouse emissions, and 82% of that (i.e. 23% of the total) from road vehicles [2]. If you could convert all of them to net zero vehicles in 10 years, that would be 2.3% emissions reduction per year. Not the full 4% needed, but not too shabby either.
