Eesti Energia AS is Estonia's vertically integrated state-owned energy company, operating generation, distribution, and retail electricity and gas services.
Scored as the Eesti Energia GROUP — the oil-shale electricity generation and shale-oil business (Enefit Power) consolidated with the renewables subsidiary (Enefit Green), not Enefit Green alone (which would score far higher in isolation). Eesti Energia operates Estonia's dominant fossil fuel infrastructure: 85% of national generation capacity, heavily dependent on oil shale. Emissions have declined from 11.3 Mt CO2 in 2018 to 3.8 Mt in 2020, driven by market forces rather than decarbonisation strategy. Critical gaps: unaudited sustainability data, no Scope 3 quantification, systemic environmental permit violations, and ongoing investment in new shale oil capacity despite IEA warnings.
Eesti Energia scores 31/100 (Below expectations) on SINK's independent climate assessment — scored from public data only. Fees pay for the review, never the result. Last verified July 2026.
That places Eesti Energia joint 564th of 812 companies scored, and 16th of 20 in Energy Supply / Utilities.
