California unveils greenhouse gas trading plan

SAN FRANCISCO, (Reuters) – California unveiled yesterday its final blueprint of a market system to curb  greenhouse gases, relaxing expected rules in the face of a weak  economy in a measure that could set the tone for the nation’s  climate policy.
By agreeing to give away virtually all necessary permits to  factories and power plants when the program starts in 2012,  rather than sell them at auction, the U.S state with the  biggest economy and population is acknowledging the challenges  of double-digit unemployment — and the reality that pollution  decreases as the economy slows.

California aims to cap total emissions of gases linked to  global warming and let factories and power plants trade for an  ever-decreasing number of permits to emit gases. In theory,  market forces will drive efficiency in the system, known as cap  and trade.

There is still a debate about the economic merits of the  plan, which planners in the Friday draft estimate will shave  about 0.1 percentage point from annual state growth.

Many Californians see such environmental regulation as  positive for the economy by spurring “green” jobs. Voters next  Tuesday could put on hold a climate change law, including the  emissions market, but polls show the Proposition 23 challenge  to the state’s climate change law is set to be rebuffed.
