Aviation's Fantastical Flight of Fancy

A Royal Society report has poured cold water on UK Aviation's net (jet) zero ambitions. The Aviation industries (plane makers, operators and travel agencies) have claimed for some time, they are working to make flying such that, in the very near future, it will have zero impact on 'greenhouse gas' emissions. This has always seemed unlikely, given the available technologies (https://www.theguardian.com/business/2023/feb/28/scientists-uk-aviation-net-zero-ambitions-half-farmland-double-renewable-electricity). The Royal Society report concludes, that there is currently no clear sustainable alternative to jet fuel. If UK aviation wished to switch to using biofuels (itself, not exactly carbon zero), 50% of the country's farmland would have to switch to fuel production. Feeding the planes by starving the people? If they decided to focus on electrical engines, the UK would have to double its renewable energy supply. Lights would be going out over the country. Pigs might fly? Some improvements may be possible but what is urgently needed is a reduction in short haul flights.
