Page 23 - Methodology to assess Net Zero progress in cities

Figure 7 reveals the annual change in total GHG emissions. It shows that 30 cities reduced their
annual GHG emissions; many of these are in America and Europe. Figure 7 shows the annual
change of capita GHG emissions over the study period in 42 cities that had reliable emission data
for at least two years. Seattle (North America), Oslo (Europe), Bogotá (South America), and Houston
(North America) are the top four cities with the largest per capita emission reduction (Bogotá is
also the second largest city in terms of total reduction).
