… greenwashed fuels and engines
On a planet already dangerously hot, just stopping new emissions won’t make us safe. The CO2 already in the atmosphere must also be cut. So using existing CO2 — whether in plants (biofuel), in waste, or via Direct Air Capture combined with hydrogen electrically extracted from water (e-fuels) — to create new CO2 emissions, the so called net zero, carbon neutral technologies and pathways, is totally counterproductive. As are offsets for the same reason.
‘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.

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.
