The systemic risk taxonomy
Hazard domains, contexts, risk classes, indicator domains, risk components, the risk chain, method fabrics, the twenty systems, platforms, domain packs and programme pillars, each node linked to the standards that govern it.
domaines d'aléas
| Node | Definition | Normes |
|---|---|---|
Atmosphère et météoatmo |
Hazards that live in the air column: storms, winds, precipitation extremes, thermal extremes, airborne particles and large-scale circulation anomalies. | |
Systèmes hydriqueswater |
Hazards of fresh and salt water: floods, water deficit, sea-level and wave hazards, ocean-state extremes and water-quality degradation. | |
Glace et neigecryo |
Hazards of the frozen Earth: snowpack and avalanche, glacier and permafrost change, floating ice. | |
Terre solidegeo |
Hazards of the crust and ground: fault shaking, eruptions, slope failure, ground deformation and surface erosion. | |
Espace et environnement proche de la Terrespace |
Hazards that arrive from or act in space: solar-terrestrial storms, impacts and orbital debris. | |
Terres et écosystèmeseco |
Hazards of the living land and sea surface: vegetation fire, forest stress, land degradation, biodiversity loss and climate-state shifts. | |
Limites planétaires et points de bascule du système Terreplanet |
Hazards of the Earth system as a whole: transgression of the boundaries that keep the planet in a stable state, tipping of large climate, ice, ocean and biome components, carbon-cycle feedbacks, and rare deep-time and cosmic catastrophes. | |
Pollution et substances dangereusespoll |
Harmful substances in air, water, soil and food, toxic releases, ionising radiation and waste-containment failures. | |
Santé et biosécuritéhealth |
Disease and biological harm to people, animals and plants, grouped by transmission route, plus systemic biological risks, chronic and mental-health burdens, drug resistance and the failure of health systems. | |
Systèmes bâtisinfra |
Failure and accident hazards of structures, energy, water, digital and space-service networks, mobility, food systems, cities, ageing assets and industrial plants. | |
Systèmes d'information et cyberphysiquescyber |
Compromise or failure of information systems, including attacks that reach physical processes, identity and trust services, systemic cyber events and platforms everything else depends on. | |
Technologies de pointe et exponentiellestech |
Hazards that arise from frontier and exponential technologies: artificial intelligence, biotechnology, advanced materials, quantum, neurotechnology, autonomy, climate intervention, space systems, digital concentration, advanced manufacturing and energy-transition technology. | |
Société, conflits et économiesoc |
Violence, geopolitical and nuclear confrontation, conflict-induced harm, humanitarian crises, governance and cohesion failure, crime, demographic and labour transitions, macro-fiscal and financial-system shocks, and loss of heritage. | |
Événements systémiques et composéssys |
Events defined by interaction rather than by one process: supply-chain disruption, cascading failure, compound multi-hazard events and the structural fragility (concentration, coupling, polycrisis) that lets them spread. |

risk classes (global, catastrophic, existential, emerging, planetary, exponential, frontier technology)
| Node | Definition | Normes |
|---|---|---|
Global riskglobal |
A hazard is global when its occurrence, its consequences or its causal chain cross national borders and act at continental or planetary scale, so that no single country can fully assess, prevent or absorb it. | |
Risque catastrophiquecatastrophic |
A hazard is catastrophic when at least one plausible scenario for it would cause global catastrophe: a very large loss of life, the crippling of global systems, or a civilisational setback that would take generations to recover from. | |
Existential riskexistential |
A hazard is existential when a plausible scenario for it would cause human extinction or a permanent, unrecoverable collapse of humanity’s long-term potential. | |
Emerging riskemerging |
A hazard is emerging when it is new, or is changing fast in nature, scale, likelihood or reach, and the evidence base for assessing it is still thin or immature. | |
Planetary riskplanetary |
A hazard is planetary when it concerns the stability of an Earth-system process: it pressures a planetary boundary, or it is, or directly drives, a tipping element whose change of state would alter the Earth system as a whole. | |
Exponential riskexponential |
A hazard is exponential when its growth or diffusion is self-accelerating, through compounding technology capability, contagion, network effects or reinforcing feedback, so that its scale can outrun linear planning and response. | |
Frontier technology riskfrontier-tech |
A hazard is frontier-tech when it arises from frontier or fast-advancing technology, through accident, misuse, unintended system behaviour or structural effects of its deployment. |

Statut
La méthodologie, la structure et les définitions de The Global Risks Index constituent un projet de travail préparatoire (2026), diffusé pour examen et commentaires et non pour mise en œuvre. Aucune valeur n'apparaît avant la publication d'une édition à partir d'une coupe de données probantes encadrée ; les valeurs comportent alors des intervalles, des classes, des sources et leur voie de correction. Les simulateurs appliquent les méthodes publiées à des nombres que vous choisissez et n'affichent jamais de valeur NXS-GRX.
Ce que NXS-GRX n'est pas
NXS-GRX est une information de recherche et d'analyse des risques. Ce n'est pas une notation de crédit ou ESG et il n'utilise aucune échelle de notation ; ce n'est pas un indice de référence pour des instruments financiers, ni une statistique officielle, ni une alerte d'urgence ou une classification officielle, ni un conseil. Il ne doit pas servir à évaluer des personnes physiques. Les classes de risque sont des bandes sur une échelle publiée, jamais des classements de pays ou de personnes.
Institutions et sources
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.
Chaque valeur porte l'attribution de ses sources, qui conservent leurs propres licences. Les noms externes ne sont cités qu'à des fins d'interopérabilité. Les textes rédigés par Nexus sont destinés à être publiés sous licence CC BY 4.0.
