Forcing higher prices for fossil fuels would be simple, fair, and effective. Why do politicians fear to do it?
Conservative and liberal economists like it. James Connaughton, President Bush's top environmental adviser, backs it. Al Gore says he's always preached it. So why isn't a carbon tax on the table in Congress as it weighs measures to curb climate change? A three-letter reason: T-A-X.
From the start of Capitol Hill's debate on global warming, the notion of taxing all uses of oil, coal, and natural gas has made lawmakers look for less direct ways to wean the nation off fossil fuels and onto alternative energies. They'd rather set caps on greenhouse-gas emissions (with allowances to trade emission permits) and tighten up regulations, such as fuel- efficiency standards.
Indeed, caps may put the US on a knowable track to, say, an 80 percent reduction in carbon emissions by 2050. But as the previous Monitor's View pointed out, the flaws in cap-and-trade plans as experienced in other nations – their complexity and vulnerability to fraud and special-interest lobbyists – would reduce the intended effect. They also take a long time to set up and get working right. And, in the end, they also raise energy prices for consumers, just not as directly as a tax.
Economists agree that the real cost of burning fossil fuels – damage to the environment and health, not to mention the cost of replacing them as they run out – isn't reflected in today's prices. A carbon tax would directly send a market signal to reduce carbon use. And it would provide an incentive for investment in renewable sources, especially if the tax is set at the source: for natural gas, at the wellhead; for coal, at the mine entrance. Oil would be charged at the refinery because petroleum products create different levels of emissions when burned.
