Oxfam, the British NGO that focuses on addressing global poverty, published a report examining carbon inequality. It looks at how the yachts, jets, and polluting investments of 50 of the world's richest billionaires are accelerating the climate crisis.

The results make for startling reading. Oxfam identified private jets belonging to 23 of the 50 richest people in the world and found that, on average, these billionaires each took 184 flights – spending 425 hours in the air – in 2023. That was equal to an average of 2,074 tonnes of carbon a year, or as much carbon as the average person would produce in 300 years, or 2,000 years' worth for someone in the global poorest 50%.
