Getting back to the topic of the Carbon Tax, I have been reading recently about Californian Governor Arnold Schwarzenegger (a conservative Republican) in 2006 and 2007 passed laws mandating that large businesses reduce their carbon emissions back to pre-year 2000 levels.
Schwarzenegger made carbon reduction a law, but I think using a Carbon Tax instead is a more flexible and less oppressive way to reduce carbon emissions.

Even conservative US Republicans accept global warming is a fact and that carbon emissions must be reduced.
The only people who don't believe in global warming are far right-wing and conspiracy-theory nutters and the usual band of dim witted people who believe what they hear on AM talk back radio.
