Thanks to Los Angeles's long history of filthy air, California is the only state that is allowed to set its own pollution standards. In the past it has used this right to make car manufacturers cut down the exhaust emissions that cause smog. On July 22nd Gray Davis, the governor of California, signed a law that extends the principle to greenhouse gases. The California Air Resources Board (CARB) is instructed to set standards for the emission of carbon dioxide and other such gases from private cars and lorries. This is a first in America.
