Switzerland 2026

スイス

Switzerland (Schweiz, Suisse, Svizzera) enters 2027 with 9.13 million residents, and people aged 65 or over (about 1.81 million) now outnumber those under 20 (about 1.80 million). Its risks come from mountains and from water.

01 · Readings

Switzerland in six readings.

Six readings that frame the Switzerland baseline, and the eight questions this edition answers, each with its status and source.

  • 9.13millionpopulation, 31 December 2025 [1]
  • 1.81millionpeople aged 65+, provisional, 2025 [2]
  • 40.1MtCO₂egreenhouse gases, 2024 [3]
  • 55.5%hydropower share of generation, 2025 [6]
  • 7%forest area protected, 2022 [25]
  • 1.4%GDP growth, 2025 [30]

02 · Sectors

Six sectors, one hexagon.

Water first, then Energy, Infrastructure, Food, Health and Biodiversity. Each count is the findings of this edition in that sector: coverage of the evidence, never a score. Infrastructure is not assessed: the edition holds no Infrastructure finding and its coupling matrix does not assess it.

  1. WAT水1 finding

    ≈20% Monitoring stations at a record low for the season, 1 April to 31 July 2026, 2026. 報告値

    Source of Alpine rivers; 97% of people use safely managed drinking water; record-low flows and lakes in 2026.

  2. ENEエネルギー2 findings

    −22.5% Change in domestic hydropower output, 2025 on 2024, 2025. 報告値

03 · Hazard exposure

The hazards this edition reads.

The edition’s own risk objects, in its order, each read across driver, exposure, vulnerability, capacity, cascade and horizon. The hexagon marks the sectors the cascade reaches; the domain beside each is an editorial reading of its hazard words.

Scenario · SCN-CHE-DRT-01

Dry year with low reservoirs and low river flows

Under this scenario, results describe a conditional season under stated assumptions. It is not a forecast, and no intervention described here has been carried out.

2 of 12 findings name a hazard in their text. Show them

  1. 1CLI → WATsnow deficit and dry spring lower rivers, lakes and groundwater
  2. 2WAT → ENEhydropower falls; 2025 output was down 22.5%
  3. 3ENE → FINimport needs and exposure to foreign supply rise in winter
  4. 4WAT → FOOpastures and farm liquidity strained; CHF 54 million in loans offered
  5. 5CLI → BIOforests and streams under stress; dead trees were 7.2% to 15.4% of trees by region
  6. 6CLI → HLThot, dry summers raise heat deaths

04 · Couplings

How the sectors carry risk into each other.

The Switzerland matrix types the twenty couplings between the five core システム. Strengths are Nexus estimates from the cited evidence and analogue events; they set the starting graph that the Q1 2027 Foundry cut will test.

Water: 4 couplings out, 4 in; Energy: 4 couplings out, 4 in; Food: 4 couplings out, 4 in; Health: 4 couplings out, 4 in; Biodiversity: 4 couplings out, 4 in. Infrastructure is not in the coupling matrix: none of the edition matrices types it, so it carries no value.

ID版Sector or systemステータスStatement
CLI-001スイスCLI Climate forcing 報告値Greenhouse-gas emissions were 40.1 MtCO₂e in 2024, 27.3% below 1990 and 22.3% below when land use is included; transport emitted 13.4 MtCO₂e and international aviation and maritime a further 5.5 MtCO₂e outside the 2030 target.
CLI-002スイスCLI Climate forcing 報告値The second contribution sets a cut of at least 65% by 2035 on 1990 as a 2031–2035 budget of 106.8 MtCO₂e, and the Climate and Innovation Act, adopted by 59.07% of voters in 2023, sets net zero by 2050.
ENE-003スイスENE エネルギー 報告値In 2025 hydropower supplied 55.5% of domestic electricity generation, nuclear power 27.2% and photovoltaics 11.8%, and final electricity consumption was 57,970 GWh.
ENE-004スイスENE エネルギー 報告値Hydropower output fell 22.5% in 2025 after a record 2024, and reservoirs stood at 46% in mid-July 2026, 16.4 points below the 20-year average; reservoirs can cover about 20% of winter-half demand.
WAT-005スイスWAT 水 報告値Between 1 April and 31 July 2026 about one-fifth of monitoring stations recorded their lowest level for the period since measurements began, and Lake Zurich reached its lowest level since 1951 on 19 August 2026.
FOO-006スイスFOO 食料 報告値The Federal Council offered CHF 54 million in interest-free operating loans to farm businesses after the 2026 drought, and the contribution text sets a goal that domestic production covers at least 50% of food needs.
CLI-007スイスCLI Climate forcing 報告値On 28 May 2025 the Birch Glacier collapsed under about 3 million m³ of rock debris, buried most of Blatten and caused one death; insured damage was put at CHF 255 million.
CLI-008スイスCLI Climate forcing 報告値Glaciers lost almost 3% of their volume in 2025 and about a quarter since 2015, and the contribution states that glaciers have lost over 65% of their volume since 1850.
HLT-009スイスHLT 健康 報告値Heat-attributable deaths were 623 in June to August 2022, 542 in May to September 2023 and 326 in May to September 2024.
FIN-010スイスFIN 金融 報告値GDP grew 1.4% in 2025 and inflation was 0.2%, and the IMF assessed the debt brake as appropriate while noting that the shift to a low-carbon economy will raise spending needs.
BIO-011スイスBIO 生物多様性 報告値About a third of species and nearly half of habitat types are threatened, and 7% of forest area was protected by 2022 against a federal goal of 10% by 2030.
SYS-012スイスSYS システミック Expert inputThe leading compound pathway for 2027 testing is a dry year with low reservoirs and low river flows that cuts hydropower and raises winter import dependence at the same time as farm and forest stress.
