Iberdrola scores 38/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.
That places Iberdrola joint 399th of 809 companies scored, and joint 10th of 21 in Energy Supply / Utilities.
Iberdrola leads European utilities on emissions and renewables—84% zero-carbon generation, SBTi-validated net-zero by 2039—but absolute emissions exceed 50 Mt CO₂e and gas operations remain material. Corporate espionage investigation and regulatory fines in US subsidiaries expose governance gaps. Transparency is strong; the transition pathway is real but incomplete.
