Every sovereign economy carries stranded-asset risk it cannot yet measure. Coal plants, oil infrastructure, carbon-intensive agriculture and high-emission manufacturing face repricing as carbon prices rise, import tariffs like the EU CBAM bite and green technology undercuts incumbents. Governments and central banks that rely on third-party transition-risk scores are flying blind: the underlying emission activity data, the policy-scenario weights and the asset-to-sector mappings are all proprietary and unverifiable.
Satellite observation closes the ground-truth gap. Multispectral and hyperspectral sensors quantify industrial activity directly — stack plumes, thermal signatures, flaring volumes, crop-type transitions, deforestation clearing rates — without depending on self-reported corporate disclosures. Night-light time series track economic intensity at plant level. Combined with sovereign carbon-price modelling, these inputs feed scenario engines that translate physical activity into stranded-asset probability curves under 1.5 °C, 2 °C and delayed-transition pathways.
The operational outcome is a national transition-risk dashboard that finance ministries, central banks and sovereign wealth funds can use to stress-test balance sheets, direct green industrial policy and defend domestic taxonomy decisions in trade negotiations. When a foreign ratings agency downgrades a sovereign bond citing transition risk, the government can rebut with its own auditable data stack rather than dispute a black-box score it did not produce.
