End to end on the longest path: about 1.1 d of proposed target service levels. Gates wait for the people named; bars with a fading end have no fixed length.

Search imagery, pass the licence gate, make scenes comparable, detect change, put exposure on H3 cells and publish a spatial risk product as tiles, with every scene and source in its lineage. The canvas shows where a request stands at the marked job; it is illustrative, not the status of a real request. Durations are proposed target service levels. Select a job for its steps, the people who act, the technology it runs on and what it produces.

Stato

La metodologia, la struttura e le definizioni di The Global Risks Index sono una bozza di lavoro preparatoria (2026), diffusa per esame e commenti e non destinata all’attuazione. Nessun valore compare finché un’edizione non viene pubblicata a partire da un taglio di evidenze regolamentato; i valori riporteranno allora intervalli, classi, fonti e il relativo percorso di correzione. I simulatori applicano i metodi pubblicati ai numeri che scegli e non mostrano mai un valore NXS-GRX.

Che cosa non è NXS-GRX

NXS-GRX è un'informazione di ricerca e di analisi del rischio. Non è un rating creditizio o ESG e non usa alcuna scala di rating, non è un indice di riferimento per strumenti finanziari, non è una statistica ufficiale, non è un allerta di emergenza né una classificazione ufficiale e non è una consulenza. Non deve essere usato per valutare persone fisiche. Le classi di rischio sono fasce su una scala pubblicata, mai graduatorie di paesi o persone.

Istituzioni e fonti

The Nexus Consortium is stewarded by three independent not-for-profit institutions: The Global Centre for Risk and Innovation (GCRI), through GCRI US in Washington, DC and GCRI Canada in Ontario, with GCRI Canada as Lead Institution, Consortium Secretariat and lead contracting organisation; The Global Risks Forum (GRF); and The Global Risks Alliance (GRA). Technology, infrastructure and service providers work with the Consortium at arm’s length under written agreements, like every other external party in the public-private-planet model, and hold no role in its stewardship.

Ogni valore riporta l’attribuzione delle proprie fonti, che mantengono le rispettive licenze. I nomi esterni sono citati unicamente a fini di interoperabilità. I testi redatti da Nexus sono destinati alla licenza CC BY 4.0 al momento della pubblicazione.

Avis en français

La méthodologie et les définitions du NXS-GRX sont un projet de travail préparatoire (2026). Le NXS-GRX est une information de recherche et d’analyse des risques : ni notation, ni indice de référence financier, ni statistique officielle, ni alerte, ni conseil. Les classes de risque sont des bandes sur une échelle publiée, non des classements.
