The state of Slovakia’s power emissions
Across the 8 Slovakia power plants carrying an asset-level CO₂ figure in this open dataset, total emissions are about 8.0 Mt CO₂/yr. The single largest emitter, U.S. Steel Kosice Works power station (coal), accounts for about 67% of that 8-plant reported subset (not of the whole country). The top three owners — US Steel Košice sro [100%], Slovenské Elektrárne AŞ [100%], Slovnaft AS [100%] — control roughly 90% of that 8-plant reported subset. Most of these plants sit in a continental Köppen climate zone.
