Wealth gaps are reflected in bigger carbon footprints, too. In North America, for example, the top 10% emits an average 73 metric tons per capita each year, compared with less than 10 tons for the poorest half.
Measured by both income and wealth, Europe is the most equitable region, according to the report. The 19% of total income earned by the poorest half of Europeans is higher than the equivalent share for that group anywhere else. Pandemic policies like income support for workers thrown out of their jobs likely helped prevent that gap from widening further.
“The Covid crisis has exacerbated inequalities between the very wealthy and the rest of the population,” said Chancel. “Yet in rich countries, government intervention prevented a massive rise in poverty.”
The World Inequality Report 2022 is based on work by more than 100 researchers around the globe, led by economists at the Paris School of Economics and the University of California at Berkeley. The first version of the study came out in 2018.
