Biofuels: better to bury than burn?

The global bioethanol industry could be disrupted by a carbon price. Somewhere between $15-50/ton, it becomes more economical to bury the biofuel crop, rather than convert it into biofuels. This would remove 8x more CO2 per acre, at a lower total cost. More conventional oil could be decarbonized with offsets. Ethanol mills and blenders would be displaced. The numbers and implications are outlined in this 12-page report.
