Future Homes carbon assessment v3: infrastructure scope explained for engineers
Reviewed by Joe Ashwell

First reported on The Construction Index
30 Second Briefing
Future Homes Hub has released version 3 of its Whole Life Carbon Assessment tool for new homes, aligned with the RICS Whole Life Carbon Assessment Professional Standard (2nd edition) and incorporating sector-specific defaults, assumptions and methodologies. The 2026 update extends the Conventions to cover site infrastructure, adding standard scopes for site preparation, estate roads, utilities and off-plot works that were previously a “data black hole”. For developers and civil engineers, this enables more comprehensive, comparable embodied carbon reporting across multi-site housing schemes and clearer allocation of infrastructure emissions.
Technical Brief
- Site infrastructure scopes explicitly cover estate roads, utilities corridors and off-plot associated works.
- Future Homes Hub positions the new scopes as closing a long‑standing “data black hole” for infrastructure emissions.
- Conventions sit under the RICS Whole Life Carbon Assessment Professional Standard (2nd edition) as sector-specific guidance.
- Adam Graveley stresses that without shared defaults and methods, benchmarking new‑build housing schemes is “extremely difficult”.
- RICS’ Fabrizio Varriale frames the Conventions as the practical route to applying the RICS standard consistently in new homes.
Our Take
Future Homes Hub’s work on this version 3 Whole Life Carbon Assessment tool sits alongside its Embodied Carbon and Resource Efficiency Board (ECREB), signalling that UK housebuilders such as Barratt Redrow are likely to see converging expectations on both software tools and governance for embodied emissions reporting.
Within our 40 Software stories, Future Homes Hub appears repeatedly in UK-focused sustainability governance pieces (water, biodiversity, embodied carbon), suggesting that Orbit Homes and other adopters of this tool could gain early familiarity with the frameworks that may underpin future regulatory baselines for new housing in England by 2026.
