People who fly in private jets are typically among the richest in the world, sometimes referred to as “ultra-high-net-worth” individuals.

The group is estimated to comprise about 256,000 people, 0.003% of the global adult population, each owning an average of $123m (£95m), according to the scientists.

The team mapped the flight routes of a number of internationally recognised figures, named in the report as only “renowned actors, singers, and directors”.

One travelled by private jet 169 times in 2023, emitting an estimated 2,400 tonnes of carbon dioxide – the equivalent of driving 571 petrol cars throughout the year.

The scientists chose not to name individuals, making clear they did not wish to point the finger at any one person.

Most of the aircraft were registered in the US (69%), followed by Brazil, Canada, Germany, Mexico and the UK.
