Synopsis: Using biofuels to replace fossil fuels actually increases CO2 emissions, just opposite of what politicians were told and believed.
Source here. "Biofuels for transportation (chiefly ethanol, biodiesel, and methanol) are being used in growing quantities in the belief that they provide environmental benefits. In fact, those benefits are very dubious. By some measures, “the net effect of biofuels production ... is to increase CO2 emissions for decades or centuries relative to the emissions caused by fossil fuel use.”"
