Norway announced that beginning next month, no car advertisements will be allowed to state that a vehicle is clean or environmentally friendly. An ad can't even state that a car produces a low amount of carbon dioxide, because that may mislead buyers into thinking that the car emits low amounts of nitrous oxide and other polluting particles.

If an advertisement does cross the line, the auto manufacturer will be fined.

Is this a case of a country just stating the truth? Yes, no car is actually good for the environment. Or is this going too far? Most people will continue to buy and drive cars no matter what advertisements appear. Shouldn't we at least try to get them to buy ones with the least negative impact?
