California to Rate Cars on Global Warming in the New Year Earth2Tech
Car buyers in California could be getting a different kind of sticker shock in the new year. Starting Jan. 1, every 2009 model year and newer car sold in California will be required to carry a label that ranks, in addition to the existing requisite smog ratings, the vehicle’s global warming impact.
California’s Air Resources Board said the new label will have two scores on a scale of 1-10 — one for smog and the other for global warming — with the average new car scoring five on both. The higher the score, the more environmentally friendly the car.
