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.

What we're watching

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.
