Embodied Carbon Estimator
Quick A1–A3 embodied carbon estimate with material lines, generic or EPD factors, and an optional A4 transport uplift.
Project
For kgCO₂e/m² benchmark (LETI/RIBA)

Indicative A1–A3 module per RICS Whole Life Carbon Assessment (2nd ed., 2023). Default factors are generic placeholders blended from ICE v3 (Bath, 2019) / typical EPDs — replace with project-specific EPD data for reporting. Optional A4 transport uses either a flat % uplift or per-line mass × distance × mode (DESNZ/DEFRA GHG conversion factors 2023); per-line A4 applies only to mass-bearing kg and m³ lines (m² lines have no mass basis). Excludes A5, B-stage use, and C-stage end-of-life. For design guidance only — always verify with a qualified engineer.
