‘SUSTAINABLE’ AVIATION FUELS
The aviation industry uses marketing greenwash and accounting tricks to mislead you into thinking that actual flight emissions from ‘Sustainable’ Aviation Fuel (SAF) are a fraction of those from fossil jet fuel. A jet never burns pure SAF, so a common 50:50 blend with fossil jet fuel doubles claimed emissions. And actual flight CO2 emissions are additionally more than claimed, by the amount of CO2 drawn down in making the fuel. Furthermore SAF still creates non-CO2 emissions twice as warming as actual flight CO2 emissions.

HYDROGEN
Hydrogen-powered aircraft will not have zero emissions, even if hydrogen is produced from renewable electricity, because it will still emit NOx and generate contrail cirrus that have a higher climate impact than CO2 today. The deployment of “green” hydrogen in aviation would require huge quantities of renewable electricity, which would deprive other sectors needing to decarbonise. Hydrogen will not be viable for medium and long-haul flights before 2050, much too late to tackle the climate emergency.

… offsets
When all sectors need to reduce their emissions to zero, the aviation industry buys/offsets the reductions of others in order to grow its own emissions. When the planet is already dangerously hot, offsets steal carbon drawdown needed to cool the planet to excuse further emissions.
