"Transportation activities (excluding international bunker fuels) accounted for 32 percent of CO2 emissions from fossil fuel combustion in 2010."
almost 6% of global C02 emmisions. I think thats substantial, but you are correct that hybrids and teslas aren't going to do much. However if we help push electric vehicles and clean power production there is obviously a substantial benefit to be reaped.
Good breakdown. As far as things that can be replaced by Priuses and Teslas (original point upthread), I think you're looking at just the 34% from passenger cars. So you end up with taking a bite out of (not zeroing) 2% of global emissions.
well - I would still say that is a bit optimistic. For instance what portion of consumers can afford a prius or tesla type vehicle?
I do think it is fair to point out that as there is more industry adoption (starting with teslas and priuses) the tech should become cheaper and better, affected other markets in other places. So directly, they aren't going to do much, but in the long term, adoption of teslas and priuses could have a substantial impact.
18.27% of global c02
