Is this your business? Add your evidence →
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. Fees pay for the review, never the result. Last verified July 2026.
That places Warner Bros. Discovery joint 505th of 847 companies scored, and 11th of 19 in Media / Entertainment / Publishing.
As at July 2026, Warner Bros. Discovery is subject to a court-blocked acquisition by Paramount Skydance — a temporary restraining order bars closing until an antitrust trial concludes or June 2027 — and to a previously announced spin-split into 'Warner Bros.' and 'Discovery Global'. Neither is complete. The entity boundary, and which successor holds HBO Max, may change; this score reflects the consolidated Warner Bros. Discovery, Inc. on FY2024 data.

Among the 19 major media / entertainment / publishing brands we've scored, Warner Bros. Discovery sits 11th of 19.
Its three lowest-scoring questions, and what the evidence didn't show.

WBD has no publicly disclosed water consumption figures, reduction targets, or waste diversion rates across any facilities.
WBD targets near-zero Scope 1+2 by 2025 (not on track) and 50% reduction by 2030, both self-set without SBTi validation or independently verified pathway.
