a, Extent at the global level. b, Extent at the regional level. These results were created by overlaying the REZ maps with the Climate Change Initiative land-cover maps60. For 1990, land-cover maps from 1992 were used. Permanent snow and ice were excluded. Results for the regions of Melanesia, Micronesia and Polynesia are not displayed due to very small REZs. The values displayed in this figure are summarized in Supplementary Table 3. For similar plots for REZs caused by high and very high road traffic volumes, see Supplementary Figs. 1 and 2.
