5.2.4 Asia-Oceania
Regarding Asia-Oceania, N4 (energy use) and N6 (less greenhouses gases) have the
most influential coefficients using the equal weighting scheme (Fig. 6c), the first
with a negative and the second with a positive value. On the other hand, applying
a proportional weighing scheme reduces the negative influence of N4. According
to the considered indicators, New Zealand (NZL) is the most sustainable country
in Asia-Oceania. Although the coefficients seem not to vary significantly using the
two initializations of weights (Fig. 6c, d), there are still some ranking differences;
for example weighting equally all the 21 indicators, Australia (AUS) is in the
