8.1Infrastructure and water
Water levels and floods shape routes. Flooding causes about 73% of expected direct damage to road and rail, and canals and rivers carry freight only while levels allow.
| Component | State | Evidence | Status |
|---|---|---|---|
| Roads and rail | flooding is the largest source of expected direct damage; protection could return a positive benefit on about 60% of exposed roads | 15 | Reported |
| Canals | canal transits are reported by the operator; UNCTAD notes congestion and transit restrictions at the Panama Canal in 2024, not quantified here | 321 | Reported |
| Ports and coasts | tropical cyclones cause 32% of port-specific risk; sea level rise is not quantified here | 17 | Reported |
| Water use of transport | not consolidated here | 30 | Expert input |
Couplings
- WAT → INF flood and low-flow disruption
- INF → WAT dredging and canal works
- CLI → WAT → INF storm surge and sea level
Evidence to bind in 2027
- canal capacity in low-flow years
- water use of ports and rail

8.2Infrastructure and food
Food moves on ports, roads and cold chains. The 2026 Hormuz disruption showed that the link runs through fertiliser freight as well as fuel.
| Component | State | Evidence | Status |
|---|---|---|---|
| Fertiliser freight | about 16 million tonnes a year pass through the strait; urea is 67% of it | 23 | Reported |
| Freight cost | freight, bunker and insurance costs rose in March 2026 and may raise food costs | 2 | Reported |
| Port reliance | low-income countries and small islands rely 1.5 and 2.0 times more on ports than the global average | 18 | Reported |
| Cold chains | depend on reliable roads and power; no consolidated series here | 1 | Expert input |
Couplings
- INF → FOO freight and ports
- TRD → INF → FOO fertiliser price transmission
- ENE → INF → FOO haulage fuel
Evidence to bind in 2027
- food price pass-through by region
- cold-chain reliability

8.3Infrastructure and health
Infrastructure shapes health through safe roads, access to care and connected services. Road crashes remain the clearest measured harm.
| Component | State | Evidence | Status |
|---|---|---|---|
| Road safety | 1.19 million deaths in 2021; leading cause of death for people aged 5 to 29; a fact sheet gives 1.16 million | 1112 | Reported |
| Cost of crashes | most countries bear a cost of about 3% of GDP | 12 | Reported |
| Connectivity | 3G or better covers 96% of people; 4% (312 million) have no mobile broadband | 5 | Reported |
| Access to care | not consolidated here | 14 | Expert input |
Couplings
- INF → HLT crashes and access
- DAT → INF → HLT telehealth and logistics
- ENE → INF → HLT fuel and power for care
Evidence to bind in 2027
- travel time to care by region
- reliability of connectivity

8.4Infrastructure and nature
Infrastructure influences almost every goal for people and the planet. Shipping and corridors also press on climate and habitats, and the nature side of the ledger is thin in this edition.
| Component | State | Evidence | Status |
|---|---|---|---|
| Sustainable development | infrastructure directly or indirectly influences all of the SDGs, including 72% of targets | 19 | Reported |
| Shipping emissions | the IMO adopted a strategy in 2023 and deferred the Net-Zero Framework in 2025 | 2627 | Reported |
| Fleet transition | 8% of the active fleet by gross tonnage is designed for alternative fuels; over 90% runs on conventional fuels | 1 | Reported |
| Habitat effects | dredging, corridors and port expansion; not consolidated here | 30 | Expert input |
Couplings
- INF → BIO corridors and dredging
- INF → CLI emissions
- BIO → INF pests and invasive species carried by trade
Evidence to bind in 2027
- habitat effects of corridors and dredging
- transport emissions on one basis

8.5Infrastructure, energy and extremes
Transport now draws on power as well as fuel, and sudden failures come from chokepoints, storms, structures and software. These are the channels the 2024 to 2026 evidence shows.
| Component | State | Evidence | Status |
|---|---|---|---|
| Fuel and power | electric cars one in four sales; transport over 10% of electricity demand growth in 2025 | 13 | Reported |
| Chokepoints | Hormuz transits fell 97%; Suez tonnage 70% below the 2023 average | 21 | Reported |
| Structures | a loose wire caused a blackout on a vessel that struck a bridge; six workers died | 22 | Reported |
| Cyber incidents | ransomware was 38% of incidents in 2021 to 2022; cybercriminals 54% of attackers | 23 | Reported |
Couplings
- TRD → INF chokepoints
- DAT → INF cyber disruption
- ENE → INF fuel and power
Evidence to bind in 2027
- chokepoint position after March 2026
- cyber incidents since 2022
