That's an excellent question.
In the short term, first, we should have a system of clear targets for the inclusion of biofuels in the transportation sector, whether in the air, on land, or at sea. Second, that system would have to be based on a common benchmark, which is carbon intensity, and then link to that the cost and the benefits people will get from using the fuel. So those would be the two essential elements to create what we call a low-carbon fuel standard.
