Life cycle assessment
The evidence base behind footprints, EPDs and credible claims.
In short
A life cycle assessment quantifies the full environmental impact of a product or process — carbon, and where relevant water, energy, acidification and resource use. It runs to ISO 14040/44 across four phases: goal and scope, inventory, impact assessment and interpretation. It is the evidence base beneath footprints, EPDs and public claims.
What it is
An LCA quantifies the full environmental impact of a product or process across its life cycle — carbon and, where needed, water, energy, acidification and resource use — to ISO 14040/44, through four phases: goal and scope, inventory, impact assessment, and interpretation.
Why it matters
It’s the rigorous foundation beneath product footprints, EPDs, eco-design and any environmental claim. As regulators tighten the rules on unsubstantiated green claims, a credible LCA turns a marketing statement into defensible evidence.
What & how we do it
The work, in the order we do it.
- Define goal, scope and functional unit
- Build the life-cycle inventory
- Run impact assessment across the categories that matter
- Interpret to find hotspots
- Document to ISO standard for third-party review or onward use in an EPD
Standards & frameworks
- ISO 14040 / 14044
- ISO 14067 (carbon)
- EN 15804 (construction)
- Aligned to the EU Product Environmental Footprint where relevant
Common questions
A PCF isolates carbon; an LCA assesses multiple impacts. A PCF is often derived from an LCA.
Yes. A compliant LCA is the technical foundation of a verified EPD.
