Ethanol worse than gasoline -- Oil companies now officially "green"?

By Christopher Mims in 60-Second Science Blog

We already knew that corn ethanol is, at best, only a little better, emissions-wise, than plain old gasoline. Now a study in Science indicates that biofuels are even worse, in terms of the net CO2 they're going to pump into the atmosphere, than the gasoline we're already putting into our cars. Mostly because of land-use changes.

"Prior analyses made an accounting error," says one study's lead author, Tim Searchinger, an agricultural expert at Princeton University. "There is a huge imbalance between the carbon lost by plowing up a hectare [2.47 acres] of forest or grassland from the benefit you get from biofuels."
