3.1Where each system stood at evidence close
WAT · Water
People without safely managed drinking water
2.2billion3.5 billion lacked safely managed sanitation in the same year.
Reported2022WHO/UNICEF JMP8
ENE · Energy
Energy-related CO₂ emissions
37.8Gt CO₂A record high, up 0.8% on 2023, as demand grew faster than clean supply.
Reported2024IEA4
FOO · Food
People facing hunger
673millionAbout 8.2% of the world population; 2.3 billion were moderately or severely food insecure.
Reported2024SOFI 20257
HLT · Health
Deaths each year from ambient and household air pollution
6.7millionAir pollution couples energy, cities and health more directly than any other pathway.
Reported2019–2020WHO14
BIO · Biodiversity
Average decline of monitored wildlife populations
−73%1970–2020. 17.6% of land and 8.4% of the ocean are protected, against 30% by 2030.
SYS · Cross-system
Natural-disaster losses · insured
224 · 108US$ bnThe sixth year above US$100 billion insured; floods, storms and fires dominated.

3.2Domain posture
Each of the twelve coupled domains is read in words, not scored. The reading states where the global evidence points; the coupling column names the dependency that carries risk across systems and borders.
| Domain | Posture at baseline | Coupling | Status |
|---|---|---|---|
| WAT | 2.2 billion people without safely managed drinking water; basin stress concentrated in arid and fast-growing regions. | WAT → FOO irrigation · WAT → ENE cooling | Reported EQL 4 |
| ENE | Record energy CO₂ in 2024; clean power at about 41% of electricity; demand rising with cooling and compute. | ENE ↔ WAT · ENE → FOO inputs | Reported EQL 5 |
| FOO | 673 million people facing hunger; production concentrated in a few breadbaskets and exporters. | FOO ← WAT, ENE · FOO → TRD | Reported EQL 4 |
| HLT | Air pollution and heat are the leading environmental health burdens; One Health risks persist. | HLT ← CLI, ENE, BIO | Reported EQL 4 |
| BIO | Wildlife populations down 73% since 1970; protection below 30% targets on land and sea. | BIO → WAT, FOO · BIO ← land use | Reported EQL 4 |
| CLI | 1.43 °C in 2025 after a record 1.55 °C; energy imbalance at a record high. | forcing on all five systems | Reported EQL 5 |
| INF | Chokepoints in shipping, power and data networks concentrate exposure. | INF → TRD, ENE, FOO | Inferred EQL 3 |
| FIN | Insured losses above US$100 billion for six years; about half of losses uninsured; debt constrains response. | FIN ← CLI · FIN → sovereigns | Reported EQL 4 |
| DAT | Cloud, cable and satellite dependencies are concentrated and only partly mapped. | DAT → ENE, FIN, HLT | Expert input EQL 2 |
| AIC | Data centres used about 415 TWh in 2024; use projected to roughly double by 2030. | AIC → ENE, WAT, MIN | Reported EQL 3 |
| MIN | Refining of key energy minerals concentrated: the top three refiners average about 86%. | MIN → ENE transition, AIC | Reported EQL 3 |
| TRD | Trade fragmentation and export restrictions raise transmission risk for food and minerals. | TRD → all systems | Inferred EQL 3 |
3.3Sector screens
All sixteen global sectors are screened on the same grammar as every national edition, so later editions can say what changed. The evidence column describes coverage of the baseline evidence, not the performance of the sector.
| Code | Sector | Baseline evidence | Exposure to watch | Evidence coverage |
|---|---|---|---|---|
| GS-00 | Cross-system | entangled crises; six of nine boundaries transgressed20 | compound and cascading shocks | PARTIAL |
