Across the 14 United Kingdom power plants carrying an asset-level CO₂ figure in this open dataset, total emissions are about 1.1 Mt CO₂/yr. The single largest emitter, Steven's Croft (cogeneration), accounts for about 35% of that 14-plant reported subset (not of the whole country). The top three owners — E.ON (formerly Powergen), Viridor, Dundee Energy Recycling — control roughly 87% of that 14-plant reported subset. Most of these plants sit in a temperate Köppen climate zone.
