Centrica discloses Scope 1, 2, and 3 emissions with DNV verification limited to operational scopes. Scope 1 emissions rose 2.8% year-on-year in 2024 despite long-term reductions. Critical weakness: credible investigations found nearly half of carbon offsets sourced from fraudulent schemes; fossil gas advocacy misaligned with climate science; unvalidated SBTi targets.
Centrica scores 38/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified October 2026.
