Chelsea Football Club scores 31/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified August 2026.
That places Chelsea Football Club joint 439th of 634 companies scored, and joint 7th of 20 in Professional Sports Clubs.
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.
