What are the LETI embodied carbon targets for buildings?

The London Energy Transformation Initiative (LETI) sets embodied carbon targets for new buildings: the 2020 target is <600 kgCO₂e/m² (Modules A1–A5), the 2025 target is <500 kgCO₂e/m², and the 2030 target is <350 kgCO₂e/m² (all excluding biogenic carbon). For structure only, LETI suggests <200 kgCO₂e/m² by 2030.

For structure only, LETI suggests <200 kgCO₂e/m² by 2030. Timber-framed buildings typically achieve 200–400 kgCO₂e/m² (A1–A5) today, already meeting or approaching 2030 targets.
