Gymshark's footprint was 351,441 tCO2e in its year to July 2025, almost all from the goods it buys and sells, and it rose on both the year before and its FY21 base. It says emissions per product are up 30% since FY21 as cotton grew in its range, and all its cotton is conventional. 86% of its own energy is renewable, backed by certificates, but it has no programme to move supplier factories off fossil power. Its SBTi-validated targets cut Scope 1 and 2 by 40% by FY2030, but its supply-chain target is per unit sold while the total rises, and its net-zero commitment has lapsed. It publishes no water footprint figure.
