U.S. Oil Fields Could Store Decades of Carbon Emissions

Depleted North American oil fields could hold billions more tons of carbon dioxide than previously estimated, providing a way to both curb greenhouse gas emissions and boost production of domestic fuels.
In a report released yesterday, the U.S. Department of Energy said the underground capacity of oil fields in the U.S. and Canada is 225 billion metric tons, or about 60 percent greater than estimates from two years ago. That’s the equivalent of more than a century of U.S. power-plant emissions at current levels.
