S.1Abstract
ASEAN, as the series reads it, is a region whose member editions in the registry are Indonesia and Singapore, set inside an association of eleven member states that share seas, rivers, an airshed and a monsoon climate. Timor-Leste became the eleventh member on 26 October 202526. The eleven states had about 700.3 million people in 2025 and a combined output of about US$4.27 trillion at current prices12. Their greenhouse gas emissions excluding land use were about 3,228 Mt CO₂e in 2024, of which Indonesia emitted 41%5. A magnitude 7.7 earthquake near Mandalay on 28 March 2025 killed at least 3,791 people in Myanmar and at least 63 in Thailand17. Prolonged flooding in Viet Nam in 2025 caused at least 200 deaths and US$1.9 billion of losses16. The haze alert for southern ASEAN was raised to Level 3 on 26 August 202648. In 2024 fossil fuels supplied 85% of Indonesia’s electricity, and renewables supplied 15.6% of the region’s primary energy in 2022 against a target of 23% for 2025818. This Baseline Edition fixes the 2026 reference state from sources that could be read at evidence close. Where a regional dataset could not be read, it shows as a designed empty state that names the source and the blocker. The edition decides nothing and compares no member state against another.
S.2Key messages
Six readings that frame the ASEAN baseline, and the eight questions this edition answers, each with its status and source.
The registry names Indonesia and Singapore. The association has eleven member states, read here as a reference group.26

What will Q1 2027 test first?Expert input
S.3Headline finding
ReportedEQL 5NRF-REGIONAL-ASN-2026-BASELINE-CLI-003
The magnitude 7.7 earthquake near Mandalay on 28 March 2025 killed at least 3,791 people in Myanmar and at least 63 in Thailand, injured at least 5,106 in Myanmar and damaged an estimated 55,000 homes, with damage valued at US$1.9 billion.
| Item | Bar, scaled to the largest value | Value |
|---|---|---|
| Myanmar | 3,791 | |
| Thailand | 63 |
Source: US Geological Survey17. Thailand’s deaths were mainly in the north and the Bangkok area. The record also reports damage to high-rise buildings in Ho Chi Minh City.
A single rupture of about 500 km on the Sagaing Fault was felt across four countries. Health services, housing, power and water failed in Myanmar, and building damage reached Bangkok and Ho Chi Minh City. Response and insurance therefore need to be read across borders17.

Indonesia and Singapore, the member editions named in the registry
S.5What each steward reads in it
GCRI · KEY T
Technical Truth
The evidence supports a coupled reading of ASEAN risk: heat, flood, smoke and earthquake act on water, energy and health together.
GRF · KEY M
Public Meaning
For most people risk arrives as a flood, a smoke day or a price change.
GRA · KEY F
Capital Meaning
Readiness implications only. Flood and earthquake loss series by member are not bound, which shows where finance-readiness evidence will matter.
NEXUS
Synthesis
ASEAN publishes strong series on output and energy and a clear haze alert system.
S.6What this edition is, and is not
What this edition is
A baseline: the state of ASEAN’s water, energy, food, health and biodiversity systems in 2026 read across Indonesia, Singapore. It reads the shared basins and grids that no single member controls, and sets out the questions the operational series will answer.
What it is not
Not a regional risk assessment, an official warning or a rating. It decides nothing about any institution or asset. Competent authorities keep every mandate they hold, and each member’s ownership of its own edition is unaffected. It does not stand for the European Union, which is a separate subject in the series.
What comes next
Q1 2027 opens the operational series with a sealed Foundry evidence cut. Each later edition reports what changed against this baseline: new observations, source revisions, method changes, scenario updates and corrections.
