Governor Jerry Brown was inaugurated for a fourth term on Monday, making climate change and carbon pollution a core part of his agenda, and calling for California "to build for the future, not steal from it." A major component of his effort will be to cut petroleum use from cars and trucks by 50 percent within fifteen years. As I explain below, not only is target achievable, but will save California's billions of dollars in fuel bills as well.
Unlike other bold pronouncements you've surely heard by past politicians, there are some strong reasons why we should believe the Governor can actually achieve these goals (beyond the Governor's sheer staying power and reputation of just wanting to, in his own words, "get sh*t done.") Here's why:
- California is already on track to meet half the target: As the Governor states, the state already has "the most integrated policy to deal with climate change of any political jurisdiction in the Western Hemisphere." Thanks to the policies under the state's clean energy and climate law, AB32, California now leads the nation in spurring more efficient cars, in efforts to develop more walkable communities and transit options, and in introducing cleaner fuels. NRDC's estimates are that with full implementation of existing and currently proposed measures, California could be on track to reduce its petroleum consumption by 25% by 2030 as compared to last year, or halfway to Governor Brown's target.
- California is poised to take the next steps: Achieving the target does not require any breakthroughs in technology or even new programs. California simply needs to do more of what it has already been doing. By building upon the existing framework and establishing new targets beyond 2020, the state can indeed halve petroleum use while lowering carbon pollution and cleaning the air. My past analysis and analysis by California Air Resources Board show that continued improvement in vehicle efficiency and deployment of electric-drive cars, trucks and buses; more sustainable development and access to transit; and continued strengthening of the Low Carbon Fuel Standard are key components.
This February, California's Air Resources Board is set to take another step through the readoption of the Low Carbon Fuels Standard, which will incentivize all fuel providers to produce and deliver cleaner fuels. As shown below, this will help lead to further reductions in petroleum use.

We are already halfway through implementation of the existing AB32 clean energy and climate law and are reaping the benefits. Perhaps the most important reason why we will halve petroleum consumption and cut carbon pollution is simply: we must. As Governor Brown eloquently stated:
This is exciting, it is bold and it is absolutely necessary if we are to have any chance of stopping potentially catastrophic changes to our climate system.... We are at a crossroads. With big and important new programs now launched and the budget carefully balanced, the challenge is to build for the future, not steal from it, to live within our means and to keep California ever golden and creative, as our forebears have shown and our descendants would expect.
