Whole Life Carbon Assessment

Full lifecycle carbon quantification from material extraction through operation to end-of-life.

We quantify the carbon footprint of every material in your building across its full lifecycle

How We Work

LCA per EN 15978, benchmarked against LETI and CRREM targets, with material substitution recommendations.

01
Quantity extraction

Extract material quantities from BIM or drawings and map to verified EPD data in OneClick LCA.

02
Lifecycle assessment

Calculate embodied and operational carbon across modules A1-A5, B1-B7, and C1-C4 per EN 15978.

03
Hotspots & substitution

Identify highest-carbon materials and test alternative specifications with quantified carbon reductions.

04
Benchmarking & reporting

Benchmark results against LETI and RIBA 2030 targets. Structure documentation for certification and ESG.
