ISO advances ISO/CD 14077 committee draft on applying chain-of-custody models in LCA (ISO 14040/14044)

ISO has a committee draft in progress: ISO/CD 14077, which addresses requirements and guidelines for applying Chain of Custody (CoC) models in Life Cycle Assessment, building on ISO 14040/14044 LCA methodology and CoC concepts (e.g., mass balance/segregation attribution). While not a binding regulation, this draft may lead to a future published ISO standard that could materially affect how organizations substantiate CoC-based claims within LCAs and how supply-chain traceability assumptions are documented. Teams relying on ISO 14040/14044-aligned LCAs should monitor ISO/CD 14077 progress for future adoption impacts.
