ESG Reporting in 2026: What the EU Simplification Changed

ESG reporting in Europe spent 2025 and 2026 being taken apart and put back together. If your understanding of the rules dates from 2024, almost every scoping conclusion you reached is now wrong — usually in your favour.

This is a guide to what the EU simplification actually did, read from the European Commission’s own timeline rather than from commentary.

Where ESG reporting started

The Corporate Sustainability Reporting Directive — Directive (EU) 2022/2464 — requires companies above a certain size to disclose the risks and opportunities they see arising from social and environmental issues, and the impact of their own activities on people and the environment.

Companies in scope report against the European Sustainability Reporting Standards, drafted by EFRAG. The first wave applied the rules for financial year 2024, in reports published in 2025.

Then the direction of travel reversed, and ESG reporting became the clearest example of the EU simplifying a file it had only just built.

The ESG reporting simplification timeline

Four moves matter more than the rest, and they do different things.

Stop-the-clock (April 2025). Parliament and Council agreed a Directive postponing the entry into application of the reporting requirements for companies that would otherwise have reported for the first time for financial year 2025 or 2026 — wave two and wave three. If you were in either group, your first reporting year moved.

The quick fix (July 2025). A delegated act revised the first set of ESRS to give wave one companies additional flexibility, and — this is the useful part — ensured they do not have to report additional information for financial years 2025 and 2026 beyond what they reported for financial year 2024. Wave one’s disclosure burden was frozen at its starting level for two years.

Omnibus I (December 2025). Parliament and Council reached political agreement on the wider simplification package.

The simplified standards (July 2026). Two delegated acts were adopted: one amending Delegated Regulation (EU) 2023/2772 to simplify certain sustainability reporting standards, and one establishing standards for voluntary use by undertakings protected by the value chain cap.

The value chain cap, and why smaller companies should care

Most ESG reporting coverage skips this, and it is the part that decides what an out-of-scope supplier actually has to do.

The single most important development for a company that is not in scope is the value chain cap.

The problem it solves is familiar to any supplier. A company below the reporting thresholds has no direct obligation — and then receives an ESG questionnaire from a customer who does, asking for whatever that customer decided it needed. Out-of-scope companies ended up doing in-scope work, without the standards, resourcing or timeline.

The cap limits what large reporting companies may demand from smaller undertakings in their value chain, and the July 2026 delegated act gives those protected undertakings a defined standard for voluntary reporting instead.

Alongside it sits VSME — a voluntary sustainability reporting standard for small and medium-sized undertakings, recommended in July 2025.

Together these change the right answer for a small supplier asked about ESG reporting. Previously: answer whatever you are sent. Now: report against a recognised voluntary standard, and point to it.

What has not changed about ESG reporting

Simplification is not repeal, and three things are worth stating plainly.

• The CSRD is still in force. The Directive was not withdrawn — thresholds, timing and standards were adjusted around it.
• Wave one companies are still reporting. They have been since financial year 2024 and the quick fix froze their burden rather than lifting it.
• Customer and investor demand is independent of the law. Procurement questionnaires did not stop when the deadlines moved, which is precisely why the value chain cap and VSME exist.

The organisations that will struggle are the ones that read “simplification” as “cancelled”, stopped work in 2025, and will restart from nothing when a contract requires it.

How ESG reporting connects to management systems you may hold

The recurring insight: most of what ESG reporting demands is data you generate anyway. What is missing is usually governance over it — ownership, definitions, and a control that makes the number reproducible next year.

Where to start with ESG reporting

1. Re-check your wave and your first reporting year. Stop-the-clock moved dates for wave two and three, and planning from a 2024 assumption wastes a year in either direction.
2. If you are out of scope, adopt VSME rather than answering ad-hoc questionnaires. One standard answer beats forty bespoke ones.
3. Know the value chain cap so you can push back on a customer asking beyond it.
4. Start from the data you already govern — environmental, health and safety, HR — before building anything new.
5. Fix definitions and ownership first. Restating a number next year is worse than not publishing it.
6. Watch EFRAG, because the revised standards came through public consultation and the pattern is continuing.

The ESG Toolkit provides 20+ editable templates covering the materiality assessment, the data collection and ownership records, the governance disclosures and the reporting structure — the parts that make next year’s numbers comparable with this year’s.
