Bellway's footprint was 1,167,882 tCO2e in its year to July 2025, mostly energy used in the homes it sells and the materials it buys. That is up from 1,019,645 t in 2024, as completions rose. Scope 1 and 2 fell 6.6%, though its electricity rests on REGO certificates. SBTi has validated a 71.5% absolute cut in Scope 1 and 2 by FY2035 from FY2019 and net zero by FY2045, but its Scope 3 targets are per m2 and Scope 3 intensity rose. Bellway Homes Ltd paid £100,000 under each of two enforcement undertakings: with Natural Resources Wales in 2025 over silt pollution, and the Environment Agency in 2023 over contaminated soil.
