I think those who make the argument that aviation is only responsible for 2-3% of emissions are missing the point that aviation is one one of the (few?) sectors where emissions are still rising, and fairly rapidly. In the 5 years to 2018 emissions from aviation increased by more than 30%
And yet, it is still less than 3% despite all this growth.
Mango are you honestly saying that in the face of rising seas and sinking islands -not some nebulous theory, it is happening right now - we should do nothing? No mitigation, no reduction, keep the pedal to the metal and increase the pace of consumption?
We are talking about the aviation industry. And I said it’s so little in terms of overall emissions it’s not worth worrying about.
If you want to make big cuts in emissions, there are great ways to do it. Nuclear power generation, moving from coal to natural gas, encouraging further urbanisation (hard sell after coronavirus though), electrification of consumer-grade vehicles, etc. etc.
All these will help way more than shaming people for flying. These also have the advantage of allowing people to maintain or improve their standard of living, which cannot be forgotten about.
