B.5Republic of Korea system card

The card through which Republic of Korea appears in the East Asia regional edition and the global series. It summarises; it does not rank.

Context

Archetype
high-income, ageing, trade-dependent economy in a seismically active region
Population
51.68 million (2025)2
Trade
imports cereals and fuel58
Target
2035 range 53% to 61% below 20187

Republic of Korea’s card sits beside its neighbours’; shared basins, grids, corridors and supply chains are read as one regional system.

EAST ASIA REGIONAL EDITION

One regional system

Korean evidence enters the water, energy, food, finance and climate sector reports through the same finding identifiers, so a correction travels everywhere at once.

GLOBAL SECTOR SERIES

Same findings, same IDs

In the global edition Republic of Korea is read against peer distributions and thresholds, never placed in a league table.

GLOBAL FLAGSHIP

Peers, not ranks
