The member editions (China, Japan, Republic of Korea) and this regional edition share finding identifiers where they read the same evidence, so a correction travels to every edition at once.

MEMBER EDITIONS

Same findings, same IDs

East Asia evidence enters the water, energy, food, finance and climate sector reports through the same finding identifiers.

GLOBAL SECTOR SERIES

Regional evidence, sector reports

In the global edition East Asia is read against peer distributions and thresholds, never placed in a league table.
