A Malaysian manufacturer supplying a listed customer can reasonably find itself asked for all of these in a single year:

  • SEDG — the Simplified ESG Disclosure Guide, because their customer is listed and is pushing disclosure down its supply chain
  • GRI Standards, because a different customer standardised on it years ago
  • IFRS S1 and S2, because the National Sustainability Reporting Framework adopts them
  • SASB, because an investor asked
Key Takeaways
  • SEDG, GRI, IFRS S1/S2 and SASB are different lenses, not competing choices.
  • Emissions figures overlap almost completely; industry-specific metrics do not overlap at all.
  • Pull figures from one approved inventory instead of retyping them into every questionnaire.
  • Sequence by obligation first, inventory before questionnaires, narrative written once and adapted down.

Four questionnaires. Substantially overlapping questions. Four separate efforts, if you treat them as four separate exercises.

Most companies do, and it is worth being clear about why that happens and what it costs.

The frameworks are not competing. They are different lenses.

It helps to know what each one is actually for, because the usual mental model — "pick the right one" — is wrong.

SEDG, the Simplified ESG Disclosure Guide, is Malaysian, published for SMEs, and structured in three progressive tiers: Basic, Intermediate, Advanced. Eleven questions, then eighteen, then twenty. Not three separate questionnaires — the same set, deepened. It exists because a supplier being asked for ESG data by a Bursa-listed customer needs somewhere sensible to start, and GRI is not that place.

GRI is the long-established general-purpose standard. Comprehensive, topic-based, and large: our question bank holds 247 GRI items. If you are asked for GRI you are being asked for breadth.

IFRS S1 and S2 are investor-facing and financially framed. S2 is the climate one, organised around four pillars — governance, strategy, risk management, metrics and targets. This is what the NSRF adopts, so for Malaysian listed companies it is not optional.

SASB is industry-specific by design, and now sits under the IFRS umbrella. This surprises people: as a manufacturer you may see three applicable disclosures where a multiline retailer sees twenty-two. That is not the system failing to find your questions. It is SASB working correctly — it publishes standards per industry, and you get the ones that apply to your industry.

Where the duplication actually is

The overlap is not evenly spread, which is why "answer once" needs qualifying.

The figures overlap almost completely. Every framework wants Scope 1, Scope 2 and eventually Scope 3. They differ in units, in whether they ask for intensity, and in wording — but the underlying number is identical, and it is already in your carbon inventory.

The narrative overlaps substantially. Governance arrangements, how climate risk is identified, whether targets exist. Phrased differently, asking the same thing.

The industry-specific parts do not overlap at all. SASB's manufacturing metrics and GRI's sector disclosures are genuinely different questions requiring genuinely different data.

The realistic claim is not "answer once, file four times". It is that the figures should never be typed twice, and the narrative should be written once and adapted — leaving you with a much smaller genuinely-distinct remainder.

Retyping your own numbers is the avoidable part

Here is the specific waste worth eliminating.

A team spends four months building an inventory. They produce a Scope 1 figure of 292.654 tonnes. Then they open the SEDG questionnaire and type "292.654" into a box, and again into GRI, and again into the IFRS submission.

Three transcriptions, three chances to fat-finger a digit, and — worse — three copies that no longer move together. Restate the inventory in March because a factor was wrong, and the questionnaires still say what they said.

In our platform, opening an assessment pulls those figures across automatically. Scope 1, 2 and 3, and their year-on-year reductions computed against the prior period. On a SEDG Advanced questionnaire that is six answers filled before anyone has typed anything.

Three things it deliberately does not do:

It never overwrites what a person wrote. Somebody who typed a figure knew something the inventory did not, and silently replacing it would be the most damaging thing this feature could do.

It leaves what it cannot source blank. An emissions intensity ratio needs a production or revenue denominator that a carbon system does not hold. That question is reported as considered-and-unavailable rather than filled with a zero. On a disclosure, a blank is a gap you can close; a zero is a claim.

It does not count as answered. Each pre-filled figure is marked as pre-filled and needs a person's name against it before the assessment can be completed. Putting a number on a disclosure is an assertion, and assertions belong to people.

Of forty numeric questions in our bank, nine can be answered from carbon data at all. The rest ask about water, headcount, governance, training hours and finances. Nine is not a large number — and it is nine transcriptions per framework per year that nobody has to make.

What order to do them in

If you are facing more than one, sequence matters more than tooling.

Start with the one you are obliged to do. For a Malaysian listed company that is IFRS S2 via the NSRF. For a supplier being pushed by a customer, SEDG Basic. Obligation first, because the others can wait and this one cannot.

Do the inventory before any questionnaire. Every framework's hardest questions are the emissions figures. Answer those once, properly, and the questionnaires become largely a formatting exercise.

Write the narrative once. Your governance arrangements do not change between GRI and IFRS S2. Write them properly for the most demanding framework you face and adapt down, rather than writing four thin versions.

Leave SASB last if it is voluntary. It is industry-specific, which means it is the least reusable effort. Valuable when an investor is asking, and poor value as a starting point.

The honest summary

There is no configuration in which four frameworks become one form. The industry-specific parts are genuinely different, and anyone claiming otherwise has not read them.

What you can eliminate is the transcription — your own figures, retyped, drifting apart. And you can write the narrative once instead of four times.

That is not a dramatic claim. It is roughly the difference between four exercises and one and a half, and for a team of two people with a day job it is the difference between doing them and not.
