In the year since California launched the nation’s largest greenhouse gas cap-and-trade program, the state has proven that climate change action can be led by states and can even spread across national borders.
Under a cap-and-trade system, companies must hold enough emission allowances to cover their emissions, and are free to buy and sell allowances on the open market. Since California held its first auction of carbon allowance credits on Nov. 14, 2012, the California Air Resources Board (CARB) has auctioned roughly 64.4 million allowances valued at $780 million. Through the smooth operation of its auctions and sales of 100 percent of 2013 allowances to date, California has demonstrated its capacity to successfully administer a cap-and-trade program.
California does not have the first emissions trading program in the United States, although it’s certainly the most ambitious. The multi-state Regional Greenhouse Gas Initiative (RGGI) was the pioneer, but California’s cap-and-trade program is more substantial due both to the size of state’s economy and the number of sectors covered. By 2015, California’s program will expand to be about twice as large as RGGI.
