Greenhouse gas emissions from tailpipes is negligible. CO2 resulting from mobile hydrocarbon combustion is approximately 2% of the annual total of CO2 released into the atmosphere. Power plants make up a much bigger source. Actually, unchecked underground coal mine fires account for 3-4% of the total itself, and putting all of those out should be a lot easier from a technical perspective than eliminating every internal combustion automobile on the planet.

Now, there's a lot of nasty crap that comes out of tailpipes that isn't CO2, and I won't deny that, but a tremendous percentage of it happens in countries we have minimal control over.
