Fig. 4: Lorenz curves for regional energy consumption and expenditure for cooling.
From: Rising Air-Conditioning Use Intensifies Global Warming
Lorenz curves for cooling energy consumption and expenditure attributable to per capita GDP (in 1990 US $ Purchasing Power Parity prices) at the global level in 2050 under the SSP119, SSP245, SSP370, and SSP585 scenarios. See Supplementary Fig. 4 for the SSP126 scenario. The yellow Lorenz curve represents global economic inequality, with data points ordered by per capita income of GCAM regions from low to high. To facilitate a direct comparison with economic inequality, we use the same regional ordering for the other Lorenz curves to illustrate the difference between global distribution of income and the distribution of cooling energy consumption and expenditure (see “Methods”). Gini coefficients of GDP, cooling energy consumption and cooling energy expenditure across all scenarios are shown in Supplementary Table 7.
