Don't be alarmed, but soon all new cars in California will have to display a global warming score, so car shoppers can make green-informed decisions. The labels will contain a car's 1-10 rating, based on emissions caused by vehicle use and emissions required to refine the car's required petroleum. A 10 ranking means the car is the best compared to its annual peers.
In California, cars produce 30 percent of global warming emissions, according to the San Jose Mercury News. Dealers must already display a smog emissions score.
It might be pretty tough to buy a car with a "1" ranking. Even so, would you like to see a global warming score on all cars?
