SAN FRANCISCO (AP) — California formally adopted America’s most comprehensive so-called “cap-and-trade” system Thursday, an experiment by the world’s eighth-largest economy that is designed to provide financial incentives for polluters to reducegreenhouse gas emissions.
State officials said they hoped other states would follow suit, calling the plan a “capstone” among the suite of tools California can use to reduce the pollution linked to climate change and cutdependence on foreign oil.
“For half a century every American president has been calling for America to move away from our dependence on foreign oil and become energy independent,” said Mary Nichols, chairman of theCalifornia Air Resources Board.
“The reason we have not succeeded in addressing our addiction to petroleum is because we did not have the right set of policy tools,” Nichols said. “Now we do. Cap-and-trade provides a reward for doing the right thing.”
The board voted unanimously to approve the final draft of its plan, a key part of the state’s landmark 2006 global warming law, AB 32, which seeks to reduce the emissions to 1990 levels by 2020.
Some businesses regulated under the program argue it will increase the price of electricity for consumers and hurt job creation by raising the cost of doing business in the state. But the program’s supporters expect cap-and-trade to spur economic recovery and innovation, by pushing business to invest in clean technologies.
While implementation of some parts of the program will begin in 2012, compliance for power plants and other of the worst polluting facilities actually starts in 2013, with others joining in 2015. In total, the plan will cover 85 percent of California’s emissions.
Former Gov. Arnold Schwarzenegger, who frequently promoted the law, called Thursday’s vote a “major milestone” in the fight against climate change.
“I have always believed that we can create a world where economic growth, energy independence and environmental protection are all achieved,” Schwarzenegger said
In general, the program will require pollution producers like refineries and cement manufacturers to buy permits, called allowances, from the state. Each permit allows for a specified amount of greenhouse gases each year, with the amount declining over time.
Companies that cut emissions and have extra allowances can then sell the permits in a marketplace; greenhouse gas emitters could purchase those allowances if they failed to cut emissions.
Polluters that reduce emissions could turn a profit if the market price for extra allowances rises above the initial cost of the permit.
A company can also meet up to 8 percent of its emissions reduction obligations by purchasing carbon “offsets,” or investments in forestry or other projects that reduce greenhouse gases.
The program, modeled on similar programs in Europe, is also designed to be able to link up with plans in other states and elsewhere to increase the size of its market for carbon allowance trading.
“Although other states and some Canadian provinces such as Quebec and British Columbia hope to link their caps to California’s, a big factor in the state’s success will be whether or not they have to go it alone,” said Jan Mazurek, director of strategy and operations for the Nicholas Institute for Environmental Policy Solutions at Duke University.
“Small markets mean fewer trading opportunities — and so potentially higher costs,” Mazurek said.
