The ultra-rich are flying more on private jets, some of which emit more carbon per hour than an average person produces in a year.

Private flights, used by just 0.003 percent of the world’s population, are the most polluting form of transport. The researchers found that passengers in larger private jets caused more CO 2 emissions in an hour than the average person did in a year.

A new study says private jet carbon pollution soared 46% from 2019 to 2023. Thursday's study figures about a quarter million of the super wealthy last year emitted 17.2 million tons of carbon dioxide flying in private jets.
