RICS CLEAR whole-life carbon coalition: key implications for built asset engineers
Reviewed by Tom Sullivan

30 Second Briefing
RICS has launched CLEAR – the Coalition for Life Cycle Emissions Alignment and Reporting – at the Sustainable Buildings and Construction Summit in Lausanne to harmonise whole-life carbon measurement across the global built environment. Co-founded with the World Business Council for Sustainable Development and the Global Building Data Initiative, and sponsored by Autodesk, CLEAR will analyse existing methodologies, resolve inconsistencies and create a globally applicable assessment and reporting framework. The coalition, involving firms such as AECOM, Arcadis, Heidelberg Materials and Morgan Sindall, will provide practical tools, technical resources and an online platform to standardise carbon data for design, procurement and asset management decisions.
Technical Brief
- CLEAR explicitly targets both construction-phase and operational emissions, i.e. full whole‑life carbon scopes.
- The coalition’s remit includes benchmarking performance, enabling cross-project comparisons currently hindered by incompatible methods.
- RICS, WBCSD and GBDI act as founding governance bodies, with Autodesk providing financial and technical sponsorship.
- Membership spans the value chain: developers, owners, material manufacturers, software vendors, investors and carbon specialists.
- Named collaborators include AECOM, Arcadis, Avison Young, Heidelberg Materials, Morgan Sindall, Once For All and OneClickLCA.
- An online platform is planned to host tools and technical resources, supporting day‑to‑day project decision workflows.
- Greater consistency and transparency in whole‑life carbon reporting is intended to strengthen trust in public‑interest outcomes.
Our Take
RICS’ move to anchor whole-life carbon work in the United Kingdom but via Lausanne-linked groups like CLEAR and the Global Building Data Initiative signals an effort to align UK-centric practice with continental European data and disclosure norms, which many large contractors already face on EU projects.
The presence of design and delivery firms such as AECOM, Arcadis, Turner & Townsend and Morgan Sindall alongside digital players like Autodesk and OneClickLCA suggests that any resulting whole-life carbon methods are likely to be embedded directly into BIM and cost-management workflows rather than sit as standalone reporting exercises.
Within our 165 Policy stories, relatively few standard-setting pieces bring together both material producers (e.g. Heidelberg Materials) and service providers, so this coalition structure could give practitioners a more consistent set of embodied-carbon assumptions from quarry through to asset management, reducing the current project-by-project variability in inputs.
