Because of climate change!
The climate is changing, the climate has always changed and always will. When it is time to worry about the climate, is when it stops changing.
But the EU charging a so-called carbon tax on aircraft flying to and from Europe,
for the entire route incluidng outside of the EU's airspace, is just a scam for money.
Nothing more and nothing less. As I posted before, it has sod all to do with climate change.
