CNNs greenest and meanest list

They're still very dirty. If you look up an 07 Mercedes E320 Bluetec, it puts out 8.1 tons of greenhouse gases/year vs the estimated 4.0 tons for an 07 Prius. From what I can tell at http://www.greencarcongress.com/2006/09/mercedesbenz_wi.html, it's only Tier 2 Bin 5 compliant vs. Tier 2 Bin 3 of the Prius made available in most states and the SULEV II/PZEV rating for Cali and CARB spec Priuses.

See http://www.epa.gov/greenvehicles/detailedchart.pdf for the emissions limits for the above scores.

As for running on veggie oil, they still have emissions. Some diesel fanboys are under the mistaken assumption that veggie oil == zero emissions.

All the vehicles http://www.driveclean.ca.gov/en/gv/vsearch...vehicletypeid=7 and http://www.driveclean.ca.gov/en/gv/vsearch...ehicletypeid=16 have emissions ratings far better than the aforementioned E320.

edit: Oh, I didn't even look at the meanest ones until now. The VW diesel Touareg emits 12.4 tons of GHG/year and gets an EPA air pollution score of 1 (Tier 2 Bin 10). That's BAD. That's basically about the worst you can be for a light duty vehicle.

Try comparing cars here. I believe they list emissions.

As for why is there a separate scale for trucks? Why are some trucks exempt? Lobbying from car manufacturers.
