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.

Etapas
  1. Area and question

    Find · You · instant
    Draw or upload an area, or pick ADM units · Event window and baseline window · Question: what changed, who and what is exposed

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.

Contato

Situação

A metodologia, a estrutura e as definições do The Global Risks Index constituem um projeto de trabalho preparatório (2026), divulgado para revisão e comentários e não para implementação. Nenhum valor aparece até que uma edição seja publicada a partir de um corte de evidências governado; os valores passam então a ter intervalos, classes, fontes e o respectivo percurso de correção. Os simuladores executam os métodos publicados sobre números que você escolhe e nunca mostram um valor do NXS-GRX.

O que o NXS-GRX não é

O NXS-GRX é informação de pesquisa e de análise de risco. Não é rating de crédito ou ESG e não usa escala de rating, não é referência para instrumentos financeiros, não é estatística oficial, não é alerta de emergência nem classificação oficial e não é aconselhamento. Não deve ser usado para avaliar pessoas físicas. As classes de risco são faixas em uma escala publicada, nunca classificações de países ou pessoas.

Instituições e fontes

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.

Cada valor inclui a atribuição das suas fontes, que mantêm as suas próprias licenças. Os nomes externos são citados apenas para fins de interoperabilidade. Os textos de autoria da Nexus destinam-se a ser publicados sob CC BY 4.0.

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.
