Capital Addressability

This working paper examines how a Common Reference Architecture can make natural-capital portfolios spatially legible without requiring projects to adopt a common metric, methodology or unit of value. Capital addressability is defined as the ability to retain a persistent spatial reference alongside a capital-related claim, allowing allocations, deployments, interventions, evidence and outcome claims to be located, compared and interrogated through time. The working framework uses H3 identifiers as persistent references to ground. These references are not assets or financial instruments; they provide stable addresses against which authored claims can resolve. The paper distinguishes between capital allocation, capital deployment, intervention claims, outcome claims and supporting evidence. It considers how spatial addressability can reveal portfolio concentration, gaps, overlapping activity and potential duplication while preserving the methodologies and vocabularies of individual projects. The architecture does not spatialise money itself, infer causation or determine value. It spatialises attributable claims about where capital acts and creates conditions in which those claims can be inspected and tested. This is a conceptual application note extending A Common Reference Architecture for Place Through Time. It is published for testing and challenge and is not proposed as a separate financial methodology or standard. Related foundational paper:Sim, G. (2026).
