In this photo taken Friday, March 7, gas prices are displayed at a Shell station in Sacramento, Calif. Starting in 2015, California motorists will be hit in the pocketbook by the state's greenhouse gas reduction law, AB32. Signed into law by Gov. Arnold Schwarzenegger in 2006, AB32 will force fuel distributors into the same cap-and-trade marketplace as utilities and major manufacturers. The oil industry says it will lead to price increase of at least 12 cents a gallon immediately, while state regulators say any price spikes could vary widely, from barely noticeable to double-digits.
