The California Air Resources Board has signed off on an updated plan to comply with the goals of A-B 32. That's the state's landmark global warming law, which requires California to reduce its greenhouse gas emissions to 1990 levels by the year 2020.
The plan is called a "scoping plan" and it includes everything from the state's cap-and-trade program to low carbon fuel standards for vehicles. The cap-and-trade efforts hit a bump in the road earlier this year when a judge ruled the state hadn't fully evaluated environmental alternatives. So the Air Resources Board updated its environmental analysis and approved that, along with an updated scoping plan.
