Isimo
The methodology, structure and definitions of The Global Risks Index are a preparatory working draft (2026), circulated for review and comment and not for implementation. No value appears until an edition is released from a governed evidence cut; values then carry intervals, classes, sources and their correction pathway. Simulators run the published methods on numbers you choose and never show a NXS-GRX value.
A country profile reads public evidence about a place. It is not a statement by or about the policy of any government, takes no position on the status of any territory, and does not imply a national programme or participation. Names follow UN M49.
Lokho i-NXS-GRX engeyikho
I-NXS-GRX iwulwazi locwaningo nokuhlaziywa kobungozi. Akusona isilinganiso sesikweletu noma se-ESG futhi ayisebenzisi sikali sokulinganisa, akusona isilinganiso samathuluzi ezimali, akuzona izibalo ezisemthethweni, akusona isixwayiso esiphuthumayo noma ukuhlukaniswa okusemthethweni, futhi akusona iseluleko. Akumele isetshenziselwe ukuhlola abantu ngabanye. Izigaba zobungozi ziyimigoqo esikalini esishicilelwe, akukaze kube ukulandelana kwamazwe noma kwabantu.
Amasiginali e-Pulse namathuba okubikezela ayimininingwane yokubuyekezwa ngabaphathi abanegunya, akukaze kube izixwayiso zomphakathi; izixwayiso ezisemthethweni zivela kuphela kubaphathi abanegunya.

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.

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.
