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.

Langkah

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.

Status

Metodologi, struktur, dan definisi The Global Risks Index merupakan draf kerja persiapan (2026), yang diedarkan untuk ditinjau dan dikomentari, bukan untuk diterapkan. Tidak ada nilai yang ditampilkan sampai sebuah edisi dirilis dari pemotongan bukti yang diatur; nilai-nilai tersebut kemudian memuat interval, kelas, sumber, dan jalur koreksinya. Simulator menjalankan metode yang diterbitkan pada angka yang Anda pilih dan tidak pernah menampilkan nilai NXS-GRX.

Apa yang bukan NXS-GRX

NXS-GRX adalah informasi riset dan analitik risiko. NXS-GRX bukan peringkat kredit atau ESG dan tidak memakai skala peringkat, bukan acuan untuk instrumen keuangan, bukan statistik resmi, bukan peringatan darurat atau klasifikasi resmi, dan bukan nasihat. NXS-GRX tidak boleh digunakan untuk menilai orang perseorangan. Kelas risiko adalah pita pada skala yang diterbitkan, tidak pernah peringkat negara atau orang.

Lembaga dan sumber

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.

Setiap nilai memuat atribusi sumbernya, yang tetap memiliki lisensinya masing-masing. Nama-nama eksternal dikutip semata-mata untuk interoperabilitas. Teks yang disusun Nexus direncanakan berlisensi CC BY 4.0 saat dirilis.

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.
