Don't live in California? Listen up anyway... California has the strictest emissions standards in the U.S., so all new cars must comply with CA's rules in order to be 50-state legal...

BTW, this article is from yesterday; the governor did sign the bill into law...from USA Today (http://www.usatoday.com/money/autos/2002-07-21-california-law_x.htm); 07/21/2002 - Updated 10:39 PM ET
Carmakers fighting California global warming law

By James R. Healey, USA TODAY

California Gov. Gray Davis plans to sign a bill into law today that environmentalists say will reduce global warming and that the auto industry says is a camouflaged attempt to regulate fuel economy, something only the federal government legally can do.

The governor's signature will ignite yet another furious battle between the auto industry and the environmental lobby over how much cars and trucks can be improved without boosting prices too high for buyers.

The auto industry is expected to sue to stop enforcement of the law, citing the fuel-economy argument. Automakers already have temporarily halted full enforcement of California's zero-emissions, electric-car mandate by convincing a federal judge that parts of it amount to back-door fuel-economy regulation.

The new law directs the California Air Resources Board (CARB) to come up with rules by the end of 2005 that "achieve the maximum feasible reduction of greenhouse gases" beginning in 2009. The main greenhouse gas is carbon dioxide, and the only way to reduce emissions of it is to burn less fuel.

Vehicles contribute a minority of the carbon dioxide in the atmosphere, but in California that's a significant 40%. Most carbon dioxide around the world comes from factories and refineries.

"By and large, it's true" that increasing fuel economy is the way to decrease carbon dioxide, acknowledges Jon Coifman, spokesman for the Natural Resources Defense Council. "But our argument is that by whatever means they choose to meet the standard, it's a tailpipe standard, and California absolutely has the right to regulate it."

Traffic-choked California legally can — and has — set exhaust-emission standards different from the rest of the USA.

Environmental groups say cutting fuel consumption should be easy using "off-the-shelf" parts and technologies that don't require expensive, lengthy development. Among them: overhead-camshaft engines instead of old-tech, push-rod designs; low-rolling-resistance tires; and continuously variable transmissions (CVTs).

But real-world experience is more complex. Ford Motor, for instance, uses sophisticated, overhead-camshaft V-8 engines in its big sport-utility vehicles and pickups. But those typically get worse, not better, fuel economy than General Motors' push-rod V-8s.

Easy-rolling tires, already on some economy cars, typically have less traction, sacrificing some braking, steering and cornering prowess for fuel efficiency.

Current CVTs aren't made for more-popular and less-fuel-efficient trucks. Truck CVTs would make the biggest difference the most quickly. Another problem: When CVTs are tuned for best fuel economy, tests show, consumers don't like how they drive. When tuned to satisfy consumers, they do little for fuel economy.

The federal Environmental Protection Agency does not consider carbon dioxide a regulated exhaust emission. carbon dioxide is expelled by all living things and is not poisonous. In fact, green plants need it to survive, and the planet needs a certain amount to remain warm enough to inhabit. Too much, though, and Earth becomes a greenhouse, trapping heat that will change the climate adversely, environmentalists warn.

While making a car "50-state legal" would require that they meet California regulations, the new California statutes don't mean that cars sold in the rest of the country need to meet California regulations.

California is the only state in the country allowed to make its own emissions regulations. While other states can mandate the California laws (and New York is already discussing it), manufacturers can (and have in the past) make two different vehicles. For years, "California emissions" were an extra cost option on many cars. I'd expect that to happen this time.

True enough. I was thinking of aftermarket parts having to be 50-state legal.

I remember watching The Price is Right (U.S. TV Game Show) as a kid in the 80s and every time they gave away a car, they made sure to say it had the "California Emissions Package."

How far is too far?
:greenchai

This Earth has been warming up since the last Ice Age without benefit of "harmful mankind." In fact, there have been at least three other ice ages and periods of heat before the polluting humans ever evolved! The environmental whackos need to pull their heads out of their butts and stop yelling "the sky is falling..the sky is falling....the sky is falling!!" They give the term "JUNK SCIENCE" a whole new meaning.
