Anthesis's footprint rose 7% to 6,359 tCO2e in 2025, almost all of it from its supply chain, while its headcount fell. Its targets are SBTi-validated: a 43% absolute cut across all scopes by 2030 and net zero by 2040. Its UK electricity is renewable, but its figures are not independently verified, and it has published no group sustainability report since 2022.
