Sustainability reporting standards: choosing a framework, or none

Sustainability reporting standards define what to disclose and how to structure it, so that reports from different organisations can be compared. Several exist, they overlap substantially, and they differ mainly in who they are written for — which is the distinction to hold on to when the acronyms start accumulating.

The honest starting point for a small business is that none of them may be necessary. Standards earn their cost when somebody is going to compare your report with somebody else's, which usually means an investor, a regulator or a large customer with a questionnaire.

The main ones, and who they are for

• GRI — the longest-established, written for a broad audience of stakeholders rather than investors specifically. Widely used voluntarily, including by organisations under no obligation.
• ESRS — the European standards attached to EU corporate sustainability reporting, mandatory for organisations in scope, detailed, and built around assessing which topics are material both to the business and to the outside world.
• ISSB standards — investor-focused, concentrating on sustainability matters that affect enterprise value, and increasingly adopted or referenced by national regulators.
• CDP — a disclosure system rather than a reporting standard, questionnaire-based, and frequently the route by which a large customer asks a supplier for climate data.
• Sector-specific schemes, which sometimes matter far more than any of the above depending on what you sell.

Choosing without over-committing

1. Start from who is asking. A customer questionnaire, an investor, a tender, or nobody in particular — each points at a different answer, and the last one points at none.
2. If a large customer is asking, ask them which framework they report under. Aligning with theirs saves you translating later.
3. If you are reporting voluntarily, pick one and say which you have used, including where you have departed from it. Partial alignment stated openly is respectable; silent partial alignment is not.
4. Do not adopt a standard you cannot resource. An incomplete ESRS-shaped report is more damaging than a short honest one that claims nothing.
5. Reuse the underlying figures. The frameworks disagree about presentation far more than about what to measure, so the collection work transfers.

Materiality is the concept worth understanding even if you adopt no framework. It asks which topics genuinely matter for your business and your impact — a software company and a haulier have almost nothing in common on this. A report covering the handful of topics that are actually material is more useful, and considerably shorter, than one that works through a full standard checklist for the sake of completeness.

The moving target

This area has changed repeatedly and continues to: scopes have been narrowed and widened, timetables deferred, and standards consolidated. Anything specific stated here about thresholds or dates would be out of date faster than the rest of the article, so the responsible advice is to check the current position with your regulator or adviser annually — and to be sceptical of any source, including this one, that states a deadline without a date of writing.

The hardest numbers to gather sit outside the company. Scope 3 emissions cover the value chain — purchased goods, transport and use of sold products — and usually dwarf a company’s direct footprint.

Where it lives

Ettex Records holds the measurements, evidence and owners that any framework needs underneath it, independent of which one you eventually cite; the report itself is covered in sustainability report and the obligation question in esg disclosure.

Being direct: there is no framework mapping, no disclosure templates and no assurance support. Those are the substance of dedicated ESG reporting products, and an organisation genuinely in scope for ESRS should be looking at one.
