01Overview

Singapore (Republic of Singapore) enters 2027 as a city-state of 6.11 million people and about US$604 billion of output in 2025, growing 5.0% that year [3] [7]. Net greenhouse-gas emissions reported to the UNFCCC were 58.59 Mt CO₂e in 2022, and the government projects a peak near 61.9 Mt around 2028 before a 2030 level of about 60 Mt [14]. The 2035 target is 45 to 50 Mt CO₂e, conditional on technological maturity and international cooperation [15] [16]. Natural gas supplied 93.1% of electricity in 2025 and solar 2.7% [8]. The IMF reports that over 90% of electricity is generated from imported natural gas, that net oil and gas imports are about 7% of GDP, and that in 2025 39% of petroleum oil imports and 26% of gas imports came from countries bordering the Strait of Hormuz [20]. Local farms supplied about 8% of fibre and 25% of protein consumption in 2025, and food came from over 180 countries and regions [27]. Water use is about 440 million gallons a day and is expected to almost double by 2065 [25]. Sea level may rise by up to 1.15 m by 2100, and with storm surge and tide the level could reach up to 5 m above today’s mean [26]. In 2025 the annual mean temperature was 28.1 °C and 29 days brought high heat stress [23]. Flood loss records, health surveillance, nature extent, data-centre load and critical-infrastructure incident series could not be read at evidence close and appear as designed gaps with their source and blocker. This Baseline Edition fixes the reference state for Singapore’s water, energy, food, health and biodiversity systems, maps the couplings through which energy, heat and sea-level shocks travel, and sets the questions the first operational edition will answer with Foundry evidence in Q1 2027. It decides nothing.

03Key findings

04Domain reading

Each of the twelve coupled domains is read in words, not scored. The coupling column names the dependency that carries risk into other systems.

05Sector screen

All sixteen sectors are screened on the same grammar, so that later editions can say what changed. The evidence column describes coverage of the baseline evidence, not the performance of the sector.

06System couplings

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

07Risk objects

Four risk objects open the portfolio. Order carries no rank. Each is read across driver, exposure, vulnerability, capacity, cascade and consequence.

• Imported fuel interruption and price shock

  Reported EQL 4

  Driver

  disruption to gas or oil flows; price spike

  Exposure

  power, petrochemicals, desalination, cold chains

  Vulnerability

  93.1% gas electricity; over 90% imported gas [8] [20]

  Capacity

  import capacity 300 MW; reserve margins not bound [9]

  Cascade

  ENE → WAT, FOO, HLT, FIN

  Horizon

  1–5 years

• Heat, heavy rain and sea-level rise

  Reported EQL 4

  Driver

  Exposure

  Vulnerability

  Driver

08Capability ladder

Existence is not readiness. Each of the fifteen capability functions is placed on the ladder by the strongest public evidence at baseline.

09Scenario

Imported-fuel interruption during a heat-stress period. A conditional statement under stated assumptions, never a prediction.

10Lenses

The baseline is read through each steward’s lens, then once as a whole. Each lens is a projection of reviewed findings, not a separate argument.

• Technical Truth

  GCRI · KEY T

  The evidence supports a coupled reading of Singapore’s risk: a 93.1% gas-fired power mix, over 90% of electricity from imported gas, a food system that is 8% local for fibre and 25% for protein, and a coast exposed to sea-level rise. Evidence is strongest for electricity, food and climate, and weakest for flood losses, nature, health surveillance and infrastructure condition, which are not bound.

• Public Meaning

  GRF · KEY M

  For most people risk arrives as a power price, a hot week or a food price. The baseline asks that public debate weigh how island geography and import links change who is reached and how fast places recover.

• Capital Meaning

  GRA · KEY F

  Readiness implications only. The protection gap is not bound, and the 2035 emissions range and the coastal protection framework point to large investment. These show where finance-readiness evidence will matter. Nothing here is advice, a rating or an approval.

• Synthesis

  NEXUS

  Singapore’s electricity, food, climate and population series are readable now; flood, nature, health surveillance and data-centre series are not. The 2027 programme should bind them, map import-linked lifeline dependencies, and measure food import exposure.

11Portfolio

Five initiatives and one Universe mission candidate are proposed for admission at the Q1 2027 alignment. They are programme objects, no partner, funder or member is attached to them in this edition.
