Build it. Run it. See where it lands.
Choose an area, the exposure that matters, the risks that start it and the systems it moves through. Press Build: the pipeline runs and the result rises on the map, cell by cell, on real open data.
Build a system and run it on the map
Pick the area, the open exposure layers, the risks and the systems; press Build. The pipeline runs in your browser and the result rises on the map.
The builder needs the page’s script: choose an area, open exposure layers, risks and systems, then build.
What runs when you build
- 面积
- The world on H3 resolution 2 (183 km cells), a UN M49 region or one country; a country site uses resolution 3 (69 km) around the country.
- 风险暴露
- People · GHSL 2025, People · WorldPop 2025, Built-up area, Ports, Airports, Roads, Railways, Rivers and lake centrelines, from Natural Earth v5.1.2 (public domain), aggregated at build time. People spreads each country’s estimate over its land cells, 35% evenly and 65% by named places. Each layer is ranked within the area.
- 风险
- Start from any of the 120 hazard families. The run expands them along 1,052 typed Hazard Standard relations (triggers, amplifies, compounds with, reduces).
- 系统
- Hazards load the ten coupled systems by their Hazard Standard exposure shares; systems pass stress along their expected couplings for sixteen steps; resilience absorbs part of it.
- Overlay
- Each cell’s impact is its ranked exposure times the stress of the systems its layers load (people: health, food, water, security, finance; built-up area: infrastructure, digital, energy, finance; ports and airports: trade; roads and railways: trade and infrastructure; rivers: water, biodiversity, food).
- 结果
- Columns rise by impact, a continuous surface shows where it concentrates, and the summary counts the people in high-impact cells. Export the run as JSON.
- What it is not
- Not a forecast, an assessment or a rating of any place. NXS-GRX estimates country couplings, hazard footprints and values in an edition before any of them is published.
状态
The Global Risks Index 的方法、结构和定义为预备性工作草案（2026），供审阅和评论，不供实施。在从受治理的证据截取中发布版本之前，不会出现任何数值；届时数值将附有区间、类别、来源及其更正途径。模拟器以您选择的数字运行已发布的方法，绝不显示 NXS-GRX 数值。
NXS-GRX 不是什么
NXS-GRX 是研究和风险分析信息。它不是信用评级或 ESG 评级，不使用任何评级尺度；它不是金融工具的基准，不是官方统计，不是紧急警报或官方分类，也不是建议。不得用于评估自然人。风险等级是已发布尺度上的区间，绝不是对国家或个人的排名。

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.

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.
