Chelsea FC has disclosed Scope 1 and 2 emissions via mandatory SECR filings but has not quantified Scope 3 supply chain emissions. The club lacks net-zero targets, multi-year emissions trajectory data, and standalone sustainability reporting. Renewable electricity and waste diversion are operational strengths; material gaps exist in water strategy, biodiversity assessment, and governance integration.
