BT Group discloses operational emissions comprehensively with third-party assurance and has achieved 52% absolute Scope 1+2 reduction. But renewable energy coverage dropped to 53% after ditching dubious certificates, Scope 3 progress lags targets at 25% of 42%, and biodiversity—material given its vast UK infrastructure—remains unmeasured and below materiality threshold.
