Biodiesel also burns far cleaner from the tailpipe than Petroleum based diesel regarding other pollutants.

For reference my car doing 70mpg in the summer does 158gpm, and the average passenger car in the US emits 423gpm. At 172mpg and 74.9gpm, your CO2 emissions are just 17.7% of the average car on the road!
But diesel is dirty!
