What the aviation industry tells you: electric planes will play a big role in decarbonisation.
What they don't tell you: due to heavy batteries, electric planes are viable only for short distances - which won't change for decades to come.

Efficiency has a problem - it's called #ReboundEffect. History shows us that "efficiency improvements" have always been accompanied by increased emissions! This is because efficiency also reduces the cost of flying and contributes to air traffic growth = emissions growth.
Emissions reductions through efficiency gains can also be cancelled out by airlines upgrading the class of seats, and by flying further or faster.
It's #COP26 and the #aviation industry has no plan - and no intention - to to do its fair share to stay below #1point5.
Instead, it's stepping up its #greenwashing.

#1 Efficiency. The #aviation industry tells us that it emits less and less CO2 per kilometre. What it doesn't tell us is that air traffic is growing much faster than efficiency is improving - resulting in higher climate pollution. #ReboundEffect
#2 Electric Flight. The aviation industry tells us the contribution of electric aircraft to reduce emissions will be significant. That's not true: the only aircraft likely to be certified this decade will be very small, we won’t see larger ones before 2050. Too late for #1point5.
