The European Union has finalized a significant simplification of its sustainability reporting rules. As part of the Omnibus I package, the European Sustainability Reporting Standards (ESRS) — the standards behind the EU's Corporate Sustainability Reporting Directive (CSRD) — have been revised to be shorter and more focused. The updated standards apply to financial years beginning on or after 1 January 2027, and companies can choose to adopt them early.
Less to report, not less to say
The biggest change is volume. The number of required data points has been cut by roughly 60 percent, with more emphasis on clear, quantitative information and less on long stretches of narrative. The rules also draw a sharper line between what a company must report and what is optional. The intent is not to say less about sustainability — it is to say it more clearly, with far less duplication.
Materiality still decides what matters
The revised standards keep double materiality at their core: a company reports on the sustainability issues that affect its business, and on the issues where its business affects people and the environment. What's new is clearer guidance on how to make that judgment. A well-reasoned, well-documented view of what is material remains the foundation of a credible report.
“The revision is an invitation to report with more focus and less clutter — and to connect sustainability to the business story rather than bury it in data.”
One connected story
A central theme of the new rules is connection: sustainability information should line up with the financial statements and the rest of the annual report, using consistent numbers and assumptions. That is exactly the alignment we help clients get right — so the sustainability report, the annual report, and investor materials tell one coherent story instead of three that don't quite match.
Working with global standards, not against them
The revised ESRS were built to sit more comfortably alongside the global standards many companies already use, including IFRS S1 and S2 from the ISSB. Where a topic isn't fully covered, the standards point to familiar references such as GRI and SASB. For companies that report in more than one market, that alignment reduces — though it doesn't remove — the effort of managing several frameworks at once.
What to do now
- Revisit what is material to your business, and write down the reasoning
- Check which of today's disclosures stay required, become optional, or drop away
- Tighten the links between your sustainability report, financial statements, and investor materials
- Decide whether to adopt the revised standards early or move across for 2027
