General Motors isn’t at all that happy with the latest 2011 ratings from the Green Car Book, which judges the new models on a point scale that includes not only fuel economy and tailpipe emissions, but also such relatively arcane measures as factory pollution and ease of recycling.
The Volt was far below the Nissan Leaf (second place), the Smart fortwo (third place) and even such conventional gas burners as the Mini Cooper (10th place) and the Hyundai Elantra (ninth).
The Volt was in 12th place, at the bottom of the list. And it didn't appear at all in the separate "Greener Choices" ranking, which lists the best cars in various categories. The Leaf got a green score of 54, the Volt 48.
