Warner Bros. Discovery discloses Scope 1, 2 and 3 emissions, but operational emissions rose year-on-year (FY2024). Scope 3 supply-chain coverage is narrow, the GHG data has no third-party assurance, and there is no water disclosure. Its first sustainability report followed a two-year gap after the 2022 merger, and its stated net-zero ambition has no SBTi validation.
Warner Bros. Discovery scores 34/100 (Below expectations) 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 July 2026.
