I appreciate that their criteria take into account the big picture, which includes the manufacturing footprint. Thus the "green" Tesla, with all its tax credits and political acclaim, doesn't fare so well, due to a thousand pounds of batteries. A car that sells for a vast sum of money really can't be all that green; the high cost indicates it "ate" a lot of resources to be born. It may be thrifty in use, but not enough to make up for the initial "green" deficit. A truly "green" car will be affordable.
