The state of Bulgaria’s power emissions
Across the 5 Bulgaria power plants carrying an asset-level CO₂ figure in this open dataset, total emissions are about 0.56 Mt CO₂/yr. The single largest emitter, Republika power station (coal), accounts for about 46% of that 5-plant reported subset (not of the whole country). The top three owners — Toplofikacia Pernik Ead, EVN Bulgaria Toplofikacia EAD [100%], Toplofikacia Sliven EAD [100%] — control roughly 83% of that 5-plant reported subset. Most of these plants sit in a temperate Köppen climate zone.
