The state of South Korea’s power emissions

Across the 83 South Korea power plants carrying an asset-level CO₂ figure in this open dataset, total emissions are about 229 Mt CO₂/yr. The single largest emitter, Taean (coal), accounts for about 13% of that 83-plant reported subset (not of the whole country). The top three owners — Korea Western Power, Korea Southern Power, Korea South East Power (KOSEP) — control roughly 44% of that 83-plant reported subset. Most of these plants sit in a temperate Köppen climate zone.
