It’s not a new idea: Raise the gas tax as a method of both funding public transportation, as well as encouraging people to use it instead of their cars. Discussions of climate change, peak oil, and sustainable development usually always at some point or another emphasize a gas tax as a particularly effective carbon tax. And as the San Francisco Chronicle notes today, the SF Bay Area is starting give the idea serious consideration:
Regional officials are taking a close look at trying to increase the Bay Area’s gasoline tax by as much as 10 cents a gallon and believe voters might agree to it as a way to help combat global warming, The Chronicle learned Thursday.
Although the regional Metropolitan Transportation Commission has been able to ask voters for a higher gas tax since 1997, a decade of polls indicated there was little chance such an unpopular idea would ever secure the necessary two-thirds approval in the nine Bay Area counties.
Now, however, with public concern building over climate change, the electorate might not be so opposed to a new gas tax as long as voters see it as a way to help the environment, officials said.
A 10-cent-a-gallon increase in the Bay Area could generate an estimated $300 million a year or more to pay for transportation-related projects. Although the money could be used for roads, the emphasis probably would be on public transit and efforts to reduce auto pollution.
But is this a workable plan – workable in both policy and political terms?
As we are well aware, any tax increase in California must get 2/3 approval, whether in the state legislature or at the ballot box. The Metropolitan Transportation Commission, which plans and helps fund transportation in the Bay Area, has found that it’s difficult to meet such a high threshold.
But apparently, linking the tax to global warming makes some difference:
The Bay Area Council, a business-backed public policy group, favors the fee approach, council spokesman John Grubb said. His organization last polled Bay Area voters three years ago about their feelings on raising the gas tax. Support then was around 50 percent. Tying the issue directly to global warming would help boost support, he said.
Whether it would boost support to 66.6% is another question entirely. One option is to charge a gas “fee” instead of a “tax” – it only requires a simple majority but, as the article notes, is much more restricted as to how funds raised can be spent.
Still, a gas tax brings with it significant costs as well as benefits.
The first is affordability. Although some opponents claim “this is probably the wrong time to raise the gas tax, given how high the cost of gas is now,” the fact is gas prices are not coming down anytime soon – if ever. Not only is peak oil a factor – increasing demand + finite supply = higher costs, but the devaluation of the US dollar is also pushing prices higher. Neither trend is going to ease anytime soon.
Because of the volatility of gas prices, I do not believe voters and drivers would actually notice the tax increase – especially if it is implemented in phases. In 2005 Washington State enacted a 9.5 cent gas tax, implemented via 3 3-cent increments between 2005 and 2007. Drivers barely noticed this, especially at a time when prices were swinging 40-50 cents a gallon.
Those who WOULD be most hurt by a gas tax are those hurt by any tax increase – the poor, the lower-income. Their neighborhoods have tended to be those least served by public transportation, although recent projects such as SF’s T-Third line have begun to address this.
That leads into my second point, which is that for a rise in the gas tax to have its intended effect of causing a shift away from single-occupancy internal combustion commuting toward public, mass transit, those alternatives need to already be in place. London has had dramatic success with a congestion charge, but it also already had the Underground, frequently rated as one of the world’s best public transit systems.
The Bay Area is better off as a whole than Southern California in terms of transit availability, but the remain both large gaps (especially in the Santa Clara Valley, but also in the East Bay) as well as places where current capacity needs significant rehabilitation (as in much of SF). This has not been helped by Arnold’s penurious funding of public transportation, evidenced by his $1.3 billion cut of mass transit funds from this year’s budget.
A gas tax, I believe, should be Step 2 of a comprehensive program to encourage sustainable, environmentally responsible transportation. Step 1 needs to be state-funded investment in public transportation to extend its reach. If there aren’t usable alternatives already in place, Californians will simply wind up paying more in gas taxes without making behavioral changes.
Also, a higher gas tax would also make sense paired with other methods to encourage public transportation and discourage driving, such as the congestion charge that SF has been considering.
