Worse off than not flying - but not worse off than Jet A? There is a 100% reduction in CO2 emissions from the fuel burn, so all that’s left to compare is the fossil fuel consumption of the Jet A and Plant based supply chains.
Those are nothing to do with the fuel itself - in countries with a 100% nuclear energy grid that would be 0. In the U.K. we were 60% renewable today, by the time this fuel is meant to be mainstream here (2050) that will be 100%
