Figure 5: The (a) total GHG emissions and (b) per capita GHG emissions of 167 cities� The most
recent data of cities are shown, which could be in different years (2005–2016), depending on the
data availability (Wei et al�, 2021)

The total and per capita GHG emissions of the 167 cities are mapped in Figure 5. As shown in
Figure 5a, the total GHG emissions ranged between 3.5 kt CO -eq and 199.7 Mt CO -eq. The top

25 (15%) of the 167 cities accounted for 52 per cent of the total GHG emissions, which are mainly
from Asian and European countries. As shown in Figure 5b, the divide of per capita GHG emissions
among cities was also huge (ranging from 0.15–34.95 t CO -eq/capita). The sector-level emissions

of cities around 2012 (108 cities in total) are shown in Figure 6.
