VERBUND is 96% renewable-powered but emissions rose 4% in 2024 as gas generation recovered. Scope 1 jumped 71% year-on-year. Hydropower dominates the portfolio and alters river ecosystems; fish-pass remediation is still in progress (71 of 92 required). Supply chain emissions are large (4.3M tCO2e) with no supplier engagement programme found. Targets are comprehensive but lack SBTi validation.
VERBUND scores 48/100 (Making progress) on SINK's independent climate assessment, scored from public data only. Scores are free. Nobody can pay to change a score, speed it up or hide it. Last verified October 2026.
