Limited evidence. Published with 2 independent parties, below our full-confidence threshold of 3. Every source cited on this page passed the same quality checks as any other score: all live, none from data aggregators. There is simply less of it.
EY has cut absolute emissions 40% since FY19 despite growing 41% in revenue, reaching 88% renewable electricity. However, supply chain scope 3 mapping remains incomplete, water data is absent globally, and governance gaps persist. Recent regulatory fines for audit misconduct (SEC $100M, FRC £4.9M) undermine credibility on internal controls.
