The United States regulates cellulosic ethanol production. Refiners must include a specific percentage of next-gen biofuel in their mix, whereas Canada does not have a position on this type of biofuel. That commitment stimulates investment even further. The United States also gives tax incentives. For every gallon of cellulosic ethanol that is produced, they allow a capital cost allowance of one dollar, as well as an accelerated capital cost allowance.
