Friedman writes in his Sunday NYTimes column:
If Keystone gets approved, environmentalists should have a long shopping list ready, starting with a price signal that discourages the use of carbon-intensive fuels in favor of low-carbon energy. Nothing would do more to clean our air, drive clean-tech innovation, weaken petro-dictators and reduce the deficit than a carbon tax. One prays this will become part of the budget debate. Also, the president can use his authority under the Clean Air Act to order reductions in CO2 emissions from existing coal power plants and refiners by, say, 25 percent. He could then do with the power companies what he did with autos: negotiate with them over the fairest way to achieve that reduction in different parts of the country. We also need to keep the president’s feet to the fire on the vow in his State of the Union address to foster policies that could “cut in half the energy wasted by our homes and businesses over the next 20 years.”
