Targeting use of SAF is why there needs to be a leap in efficiency. SAF is very costly compared to fossil fuels.
Co2 tax changes the decisions made within the brain of the leaders of the airline financial analysis team. A Co2 tax can reduce Co2 emission by 40% easily, and this is without any new technology being invented. It can take effect within 1 year. We are just going slow and inventing technology to make it easier for industry and more profitable. But the reductions are very easy. Actually humanity already achieved huge Co2 reductions thousands of years ago. We have the technology.
Please enlighten me on what technology currently exists that can reduce aviation industry CO2 emissions by 40% "easily" without reducing passenger miles flown.
Easy. #1, carbon tax. A $250 leisure fare may be $600 instead. The amount of flying people can truly afford, without borrowing from the environment, may be 40% lower than 2019. We can cut ASM and RPM by 40% (which we already did in 2020 AFAIK).
Zoom is another technology that allows most business meetings to be done virtually, which is not only important for environmental reasons, but also gender equity, to ensure women have an equal access to business meetings and promotions. Long story short, tax carbon to the point where Co2 emission goes down 40%. This is a simple policy that can roll out this year
