 You know, the airline industry, they're working to lower their carbon footprint. Pretty much everyone agrees SAFs are a way forward, as the idea of flying around in battery-operated planes, you know, that lacks viability. So the U.S. says crops that could be used for human food or animal feed, so think corn, soy, sugarcane, they're good to be used and even qualify for a tax credit. So that sounds reasonable. The EU, however, says they are not good. They are excluding crops they call feedstock, which would be in that human food or animal feed category.
