Overview

We quantify the total carbon footprint of a building across its full lifecycle — from raw material extraction and manufacturing (embodied carbon) through operational energy use, maintenance, and end-of-life disposal or reuse.

Why It Matters

As operational carbon reduces through electrification and grid decarbonisation, embodied carbon is becoming the dominant share of a building’s lifetime emissions. Regulatory frameworks are catching up — whole life carbon assessment is increasingly required by rating systems (LEED, BREEAM, Estidama) and is expected to become mandatory in many jurisdictions. Understanding your building’s full carbon picture is essential for credible net zero claims and investor-grade ESG reporting.

Our Approach

We conduct lifecycle assessments (LCA) in accordance with EN 15978 and ISO 14040/14044, covering modules A1–A5 (product and construction), B1–B7 (use stage), and C1–C4 (end of life). We model embodied carbon at key design stages, benchmark against industry targets (such as RIBA 2030 Climate Challenge, LETI, and CRREM), and identify material substitutions and design changes that deliver the greatest carbon reductions.
