Infrastructure
Lifecycle data infrastructure as the prerequisite for credible long-horizon analysis.
Modelling transition risk credibly at scale requires lifecycle data on the underlying assets and materials: where they came from, how they have been operated and maintained, what their actual carbon and material footprint looks like, and how they pass from one owner or use to the next.
My main conceptual project in this area is the Aviation Trust Network — a proposed framework for digital identities and verifiable credentials applied to aircraft and components. It is currently at the architecture and working-paper stage.
A fuller account of ATN, its relationship to the Digital Product Passport work emerging in adjacent value chains — in particular biocircular construction, and the book-and-claim path toward DPP-style traceability in sustainable aviation fuels, which would let passengers assess the sustainability claims of the airlines they fly with — and the broader coordination challenge involved, will be added in subsequent iterations of this page.
The most recent ATN paper, Digital Airworthiness Platform — DPP-ready (August 2025), sets out the technical and governance architecture.
