That's a good question.
I think it requires companies and company leaders to be able to justify the decisions they make and how they spend their company's resources. I think a lot of company executives are getting some pressure in this area.
At the same time, I think air travel is considered a critical form of transport. In some jurisdictions, like in Europe, you are seeing some countries regulating that short-haul flights should be replaced by trains under a couple of hours of distance. I think, overall, the view is that an industry like the air industry needs to continue and it's going to take longer to decarbonize. It's one of the industries where there's talk of the need for carbon offsets because it's hard to totally switch over, but other industries can move more quickly to provide a balance.
