SEDG & ASEDG, explained
Bursa Malaysia's SEDG and the ASEAN-level ASEDG give SMEs across Southeast Asia a simplified, standardised way to disclose ESG data — often to answer requests from the larger listed companies they supply. Here is what they cover, how their tiers work, and how to produce a report alongside a VSME-aligned Passport.
Last updated:
Summary for orientation only. SEDG and ASEDG are simplified disclosure guides, not listing mandates on SMEs — this is not legal advice.
- SEDG is Bursa Malaysia's Simplified ESG Disclosure Guide for Malaysia; ASEDG is the ASEAN-level counterpart for the rest of the region.
- They are structurally identical — the same E, S and G disclosures and the same Basic / Intermediate / Advanced tiers.
- They exist mainly to help SME suppliers answer ESG requests from the larger listed companies they sell to.
- EcoDiligence detects the right regime from your country of operation and fills the Basic tier automatically.
- You get a VSME-aligned Passport and a SEDG/ASEDG report from one set of answers — the downloadable Excel report is a Pro feature.
What is the Bursa Malaysia SEDG?
The SEDG (Simplified ESG Disclosure Guide) is a guide published by Bursa Malaysia, the Malaysian stock exchange, to help companies — especially the SME suppliers of listed issuers — disclose ESG information in a simplified, standardised form. As large Malaysian companies report their own sustainability data, they need consistent information from their supply chains, and the SEDG gives their smaller suppliers a common template to answer with.
It is a disclosure guide, not a listing rule imposed on SMEs — the mandatory sustainability reporting that applies to Bursa-listed issuers is a separate matter. For an SME, the SEDG is the practical, proportionate way to respond.
What is the ASEDG?
The ASEDG is the ASEAN-level Simplified ESG Disclosure Guide — the regional counterpart to Malaysia's SEDG, intended to give SMEs across Southeast Asia the same simplified disclosure structure. In EcoDiligence, ASEDG applies to the ASEAN member states other than Malaysia: Brunei, Cambodia, Indonesia, Laos, Myanmar, the Philippines, Singapore, Thailand, and Vietnam. Malaysia uses its own national SEDG.
The shared structure: three tiers across E, S and G
Because SEDG and ASEDG share the same design, the practical experience is the same wherever you are in ASEAN. Disclosures are grouped under Environmental, Social, and Governance and organised into three tiers so a company reports as much as it is ready for:
Everyone
Basic
The foundational data points most SMEs can report immediately — energy, emissions, workforce, and governance basics. EcoDiligence fills these automatically from your Passport.
Going further
Intermediate
A more detailed layer — additional environmental and social metrics for companies whose stakeholders ask for more depth.
Most detailed
Advanced
The fullest set of disclosures, for SMEs with the most demanding buyers, lenders, or investors.
EcoDiligence handles the Basic tier for you and adds a curated set of Intermediate and Advanced questions as an optional layer, so you can go deeper without reading the full guide.
Who they are for
SEDG and ASEDG are aimed at small and medium enterprises across ASEAN— most often SMEs that supply larger, listed companies and receive ESG or sustainability questionnaires as part of procurement. If that describes you, a SEDG/ASEDG-aligned profile is a direct, recognised way to respond. For the broader “a customer sent me a questionnaire” situation, see our step-by-step guide.
SEDG / ASEDG and VSME — you get both
You do not have to choose between frameworks. EcoDiligence always produces a VSME-aligned Passport — the EU's voluntary SME standard and a widely recognised baseline — and, for a Malaysian or ASEAN profile, additionally maps the same data to the SEDG or ASEDG structure. The climate figures in your report also line up with the global IFRS S2 baseline. One set of answers, mapped to whichever framework a given stakeholder recognises.
How EcoDiligence produces your SEDG / ASEDG report
Regime detected automatically
Enter your country of operation and EcoDiligence applies SEDG for Malaysia or ASEDG for other ASEAN countries — no manual selection.
Basic tier auto-filled
Your existing Passport data — energy, emissions, workforce, governance — populates the Basic-tier disclosures, so free profiles already meet the Basic tier.
Intermediate & Advanced (Pro)
An optional curated question set adds the deeper tiers, delivered through the same Advanced Disclosures layer as VSME and IFRS S2.
Downloadable Excel report
Pro profiles export a SEDG or ASEDG report in Excel, alongside a matching badge and section on the public Passport and PDF.

Frequently asked questions
This page summarises the Bursa Malaysia SEDG and the ASEAN-level ASEDG for orientation only and is not legal advice. SEDG and ASEDG are simplified disclosure guides for SME suppliers, distinct from the mandatory sustainability reporting that applies to listed issuers; details may change. For the official Malaysian guide, see bursamalaysia.com. EcoDiligence ESG Passports are self-reported summaries structured for ESG disclosure workflows. Content is not independently assured.
