I applaud him for critical thinking but these type of threads that focus on a single point ignore the big picture.

He may reduce or increase his personal pollution but what about all the pollution upstream that got that gallon of gas in his tank? I have never seen a hard estimate but from what I was able to read roughly 100x the pollution emitted from the car itself burning a gallon of gas is created during the exploration, drilling, cracking, refinement and transport of that 1 gallon of gas to his car. This includes many types of pollution more hanous than his exhaust that go in land, sea and air. It also requires manpower and a variety of other resources that aren't fully explained or mentioned that are needed as a result.

I would stand by reducing fuel consumption is more important than slight changes in exhaust makeup.
