What we found
Desk review: Southampton FC does not publish Scope 1/2/3 emissions; St Mary's runs on 100% renewable electricity with LED floodlights; the 450-panel solar install (Jan 2026, ~33 t/yr) is at the Staplewood TRAINING campus, not the stadium. Renewable electricity + LED but no disclosure -> Certified, transparency gap noted.
