Significant gapsPending Review

OpenAI operates massive compute infrastructure with zero disclosed emissions data across Scope 1, 2, or 3. The company dismisses water concerns as 'fake,' relies on unverified renewable claims through Microsoft, and deploys natural gas plants for major new facilities. Rapid expansion to 10 GW by 2029 proceeds without carbon pathway, baseline data, or board-level sustainability oversight.
