But all flights worldwide only account for 2% of all CO2.
Industrial output accounts for 22% and electricity 28%.
If we regulated all electricity to be carbon neutral, that would make electricity cost more and harm the economy, but it would have a huge effect on emissions.
Flying just isn't that important to climate change, but it is quite important to the economy. Not a lot of goods move by air, but people do. A lot of the world depends on tourism. For some countries, it is the main contributor to their GDP.
Yeah, I fly a few times a year, sometimes to the other side of the planet, for business. And also for tourism where I spend a bunch of money buying local goods.
I also use a lot of energy. I pay extra to make sure that energy all comes from carbon neutral sources. That makes a much bigger difference to climate change than using a plane.
