Isn’t the pollution from millions of people travelling to her concerts bigger than from the single plane? Who is responsible for that?
If she is, then that’s the bigger issue than the plane. If the concert goers are, then they also share responsibility for the plane’s pollution.
My point is that a concert only exists due to concert goers paying for it, supporting it, and coming to it. It doesn’t seem unreasonable to me that the total environmental impact of the concert can then by divided by all the people who attended it, including everyone carrying their small share of responsibility that the singer travelled to sing for them.
I absolutely agree it’s mainly her responsibility for the choice of the mode of transport, but I do think everyone who buys a ticket is “complicit”, as everyone knows that’s how she does it and are still happy to support it. And I don’t blame any individual person, because for any individual person the share of responsibility is very small.
