The richest 1% of the world’s population produce 15% of the world’s carbon emissions, double the emissions of the poorest 50%. On average, they emit more than 70 tonnes of carbon dioxide per person per year, 30 times more than we can afford to emit if we try to avoid exceeding the 1.5 degrees of global warming. If we consider individuals rather than industry, 10% of European citizens are responsible for 27% of the continent’s total pollution. One of the billionaires’ favourite toys, a superyacht—which is kept on constant standby—emits around 7,000 tonnes of CO2 per year.
