Whole-Life Carbon
The upfront embodied carbon emissions (RICS Categories A1 – A5) of our homes in 2025 was 335.6kgCO2e/m2 – below the 2025 target for the UK Net Zero Carbon Building Standard. The whole-life embodied carbon emissions (RICS Categories A1 – C4, excluding B6 and B7) of our homes in 2025 was 628.85kgCO2e/m2 – below the 2025 target for the RIBA Climate Challenge.
Construction Waste
