A plain-English guide to the CSDDD, built to stay accurate.

CSDDD Navigator is a free, independent hub explaining the EU Corporate Sustainability Due Diligence Directive (CSDDD, also called CS3D) in plain English. No software to sell. No consulting upsell. We are not affiliated with the EU. Just the rules, kept current.

Find your way through corporate sustainability due diligence.

How we keep this accurate

The CSDDD changed dramatically in early 2026 through the “Omnibus I” simplification package, so accuracy is the whole job. Here's how we approach it.

Independent: no software to sell, not affiliated with the EU

We don't sell compliance software and we don't run a consultancy. We are not a regulator, and we are not affiliated with the European Union or its institutions. Nobody pays us to point you at a product. That's deliberate: it means our answers can stay neutral and our only goal is to explain the directive clearly.

Where our facts come from

Every factual claim traces back to an official source: the directive itself on EUR-Lex (Directive (EU) 2024/1760, as amended by the Omnibus I act, Directive (EU) 2026/470), the European Commission's sustainability due diligence pages, and the international standards the CSDDD is built on, the OECD Guidelines for Multinational Enterprises and the OECD Due Diligence Guidance for Responsible Business Conduct, and the UN Guiding Principles on Business and Human Rights. We link the source so you can check our work.

How we keep it current

Key pages carry a visible “Last updated” date. We actively track the Omnibus changes: the new thresholds, the 26 July 2028 transposition and 26 July 2029 application dates, and the Commission guidelines still to come. When something material changes, we revise the affected pages and send it to subscribers of The CSDDD Brief.

When the rules aren't settled

Sometimes the law is genuinely in flux. The standalone climate transition plan duty, for example, was significantly scaled back under Omnibus I, and civil-liability rules are now left to national law and still settling. When that's the case, we say so plainly and flag it, rather than guess. We'd rather tell you “this isn't decided” than sound more certain than the facts allow.

This is guidance, not legal advice

This is guidance to help you understand the CSDDD, not legal advice. We've worked hard to get it right and to link our sources, but for decisions specific to your business, confirm with the official sources we link or a qualified adviser. We can't guarantee compliance, and you should be wary of anyone who says they can.

Who's behind it

CSDDD Navigator is a free information service, maintained as an independent editorial project, not by a regulator and not by a vendor. It is the sister site to EUDR Navigator and reuses its design system.
