| 12 | Ocean Winds | OSW developer / operator | 11.0 | 25.2 | 13.0 | 49.2 | Limited |
Targets and forward growth signal direction of travel; capped at 30% so companies cannot lead on promises alone.
Largest weight, the 'is it actually happening' pillar, with OSW asset-level and emissions-progress evidence concentrated here.
Governance is the credibility multiplier: regulatory alignment, supplier due diligence and external assurance.

Score bands
Quantified targets across all pillars, strong asset-level OSW evidence, independently assured.
Solid quantification, OSW evidence present, minor gaps in Scope 3 or biodiversity detail.
Targets and policies in place, but OSW-specific or supply-chain evidence partial.
Mostly Group-level qualitative evidence; OSW asset-level disclosure thin.
Material gaps on targets, asset-level evidence and external assurance.
