| Node | Definition | ધોરણો |
|---|---|---|
Atmosphere and weatheratmo |
Hazards that live in the air column: storms, winds, precipitation extremes, thermal extremes, airborne particles and large-scale circulation anomalies. | |
Water systemswater |
Hazards of fresh and salt water: floods, water deficit, sea-level and wave hazards, ocean-state extremes and water-quality degradation. | |
Ice and snowcryo |
Hazards of the frozen Earth: snowpack and avalanche, glacier and permafrost change, floating ice. | |
Solid Earthgeo |
Hazards of the crust and ground: fault shaking, eruptions, slope failure, ground deformation and surface erosion. | |
Space and near-Earthspace |
Hazards that arrive from or act in space: solar-terrestrial storms, impacts and orbital debris. | |
Land and ecosystemseco |
Hazards of the living land and sea surface: vegetation fire, forest stress, land degradation, biodiversity loss and climate-state shifts. | |
ગ્રહીય સીમાઓ અને પૃથ્વી-પ્રણાલીના નિર્ણાયક બિંદુઓplanet |
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 and hazardous substancespoll |
Harmful substances in air, water, soil and food, toxic releases, ionising radiation and waste-containment failures. | |
Health and biosecurityhealth |
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. | |
Built systemsinfra |
Failure and accident hazards of structures, energy, water, digital and space-service networks, mobility, food systems, cities, ageing assets and industrial plants. | |
Information and cyber-physical systemscyber |
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. | |
અગ્રણી અને ઘાતાંકીય ટેકનોલોજીtech |
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. | |
સમાજ, સંઘર્ષ અને અર્થતંત્રsoc |
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. | |
Systemic and compound eventssys |
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. |

03Hazard Standard
risk classes (global, catastrophic, existential, emerging, planetary, exponential, frontier technology)
| Node | Definition | ધોરણો |
|---|---|---|
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. | |
Catastrophic riskcatastrophic |
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. |

Propose a change to the taxonomy
The taxonomy is a proposal under the standards development process.
સ્થિતિ
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.
What NXS-GRX is not
NXS-GRX is research and risk-analytics information. It is not a credit or ESG rating and uses no rating scale, not a benchmark for financial instruments, not official statistics, not an emergency warning or official classification, and not advice. It must not be used to evaluate natural persons. Risk classes are bands on a published scale, never rankings of countries or people.
Institutions and 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.
Every value carries the attribution of its sources, which keep their own licences. External names are cited for interoperability only. Nexus-authored text is intended for CC BY 4.0 on release.
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.
