Industrial ecology for construction: natural materials and sector roadmaps

The lab's first body of work, 2022 to 2025. Roadmaps that move construction from carbon-intensive synthetic products toward industrial-ecology pathways, and evidence that brings natural and under-represented materials into public decarbonization roadmaps.

The question

How can construction move from carbon-intensive synthetic products to industrial-ecology pathways that favour natural and under-represented materials, and how can those materials enter public decarbonization roadmaps?

What the figures leave out

Public roadmaps and purchasing rules are built around the materials that are already measured. Natural materials with a smaller footprint can be left out simply because the evidence on them has not been assembled in the form those roadmaps require.

Approach

We applied industrial ecology to building design and supply: tracing material flows, comparing materials on their environmental accounts and drafting sector roadmaps. For under-represented material industries, we assembled the peer-reviewed evidence that public roadmaps and taxonomy criteria require.

Where it stands

Completed

Completed, 2022 to 2025. This work began as a research initiative within the Engineering Division of Bouygues Immobilier (see the lab's history) and continued after the lab became independent in 2025.

The decision it informs

The material choices of developers and contractors, and the inclusion of natural materials, such as structural stone, in national and EU roadmaps and taxonomy criteria.

INSTRUMENTS · Sector roadmaps; evidence for inclusion in public roadmaps.

What the work required

  • Industrial ecology applied to the construction sector
  • Environmental accounting of construction materials
  • Advocacy grounded in peer-reviewed evidence for under-represented material industries
