Billionaires generate obscene amounts of carbon pollution with their yachts and private jets – but this is dwarfed by the pollution caused by their investments,” said Oxfam International’s inequality policy adviser Alex Maitland.

Through the corporations they own, billionaires emit a million times more carbon than the average person. They tend to favour investments in heavily polluting industries, like fossil fuels.

Private jets aren't great, but they're objectively a tiny part of emissions. According to the EPA,

The largest sources of transportation greenhouse gas emissions in 2021 were light-duty trucks, which include sport utility vehicles, pickup trucks, and minivans (37%); medium- and heavy-duty trucks (23%); passenger cars (21%); commercial aircraft (7%); other aircraft (2%); pipelines (4%); ships and boats (3%); and rail (2%).

If we banned private jets, we'd decrease emissions by somewhere under 2%, assuming we're just banning the larger luxury private jets Taylor Swift is chauffered in, not the recreational 2-4 seat single prop aircraft that pilots own. Taylor Swift's jet was in the news for polluting as much as 1,184.8 average people. That's not equitable, but objectively it's a pretty small part of the problem.

Passenger vehicles are 58% of transportation emissions. If you include freight trucks, they're 83% of transportation emissions. Insisting on eliminating 2% of emissions before we even think about reducing 58% of emissions is the definition of putting the cart before the horse.

The problem with driving isn't with individual people deciding to drive instead of walking 2 hours to get groceries. It's the car-centric Euclidean zoning and sprawling (sub)urban design that makes driving the only practical option. If you can get the average person to drive 4% less by e.g. giving them a neighborhood pub they can bike to in 5 minutes, you've done more to decrease emissions than by grounding every private jet.

I mean, don't get me wrong - we can do both at the same time. But Taylor Swift's emissions are objectively more a matter of equity and optics than substance. You don't fix climate change by hyperfixating on eliminating 2% of emissions.
