The state of Finland’s power emissions

Across the 31 Finland power plants carrying an asset-level CO₂ figure in this open dataset, total emissions are about 2.5 Mt CO₂/yr. The single largest emitter, Salmisaari B (coal), accounts for about 29% of that 31-plant reported subset (not of the whole country). The top three owners — Helsingin Energia, Kilpilahden Voimalaitos Oy [100%], Vantaan Energia Oy — control roughly 62% of that 31-plant reported subset. Most of these plants sit in a continental Köppen climate zone.
