Correct, which is why I suggested considering a used one. As to the other emissions, as Gary Locke, the former governor of Washington state once said, "don't let the perfect be the enemy of the good". Biodiesel is a big improvement on dino-diesel or regular gasoline, but that's another forum ...

BTW Ken, did you hear about my plug-in wannabe site, http://phev.wikispaces.com ?
It includes some bumper stickers in Japanese, 例えば、”大きくなったらプラクイン・ハイブリッドになりたいな！” Please check out the Japanese language products here:

Could you possibly help me promote this in Japan?
