howdy,

here is the criteria for their "Green Car" book:

<snip> We analyze automakers' test results for fuel economy and emissions as reported to the U.S. Environmental Protection Agency and the California Air Resources Board, along with other specifications reported by automakers. We estimate pollution from vehicle manufacturing, from the production and distribution of fuel and from vehicle tailpipes. We count air pollution, such as fine particles, nitrogen oxides, hydrocarbons and other pollutants according to the health problems caused by each pollutant. We then factor in greenhouse gases (such as carbon dioxide) and combine the emissions estimates into a Green Score that runs on a scale from 0 to 100. The top vehicles this year score a 57, the average is 27 and the worst gas-guzzlers score around 10. Further information can be found on the GreenerCars.com Methodology page.

<un-snip>

plus the toureg fails miserable in their three biggies: tailpipe emissions take under normal driving conditions, fuel economy, and curb weight.

<snip>

Three types of vehicle-specific data form the basis of the ACEEE's Green BookR ratings: tailpipe emissions, given by the emissions standard to which a vehicle is certified; fuel economy, based on EPA test cycles; and vehicle mass (curb weight).

<un-snip>

I'd still drive one, if I could plunk 57k.

Maybe something to do with the high particulate (soot) and NOx levels from diesels?
