Budget strains emissions plan

From this article:

California's budget is starting to cramp its environmentally hip style.

Gov. Arnold Schwarzenegger is proposing to borrow money from special funds to pay for implementing the state's ambitious plan to roll back greenhouse gas emissions to 1990 levels by 2020.

The administration wants to borrow the money from various funds filled by driver's license and vehicle registration fees, as well as tap into recycling deposits, to help pay for 212 positions at a dozen state agencies.

I'd like to see a cost/benefit analysis here--what is the cost of filling these 212 positions, and what is the measurable "benefit" in terms of expected degrees of global temperature decrease.
