Why are people still flying to climate conferences by private jet?

Rishi Sunak, David Cameron and King Charles are just three of the more than 70,000 delegates from nearly 200 countries at the latest UN climate summit in Dubai, COP28. But they are among hundreds who will have traveled there by private jet. In fact, the UK prime minister, foreign secretary and king even traveled in three separate planes.

At COP27 in Egypt last year, around 315 private jet journeys took place. This is an extraordinary statistic, especially as fewer world leaders attended that COP, as many were busy at a G20 summit in Bali.
