Understanding CSRD: what businesses need to know
A practical overview of the EU’s Corporate Sustainability Reporting Directive — double materiality, assurance, value chain data, and what to do about it.
If your organisation sells into Europe, has a European subsidiary, or supplies a company that does, you have probably heard CSRD mentioned with a note of alarm. The Corporate Sustainability Reporting Directive is the European Union’s sustainability reporting law, and it is deliberately more demanding than what came before it.
What it is
CSRD requires in-scope companies to report on sustainability matters — climate among them — using a common set of European Sustainability Reporting Standards. It replaces an earlier, lighter directive, widens the range of companies that must report, and moves sustainability information into the management report alongside financial statements.
Three things that make it different
Double materiality. Most frameworks ask how sustainability issues affect your business. CSRD asks that and how your business affects people and the environment. Both directions have to be assessed and explained.
Assurance. Reported sustainability information is subject to assurance. That is the pivot point: numbers that were previously prepared for a brochure now have to withstand the same kind of examination as financial figures.
Value chain reporting. The scope reaches beyond your own operations into your value chain, which for most organisations means Scope 3 emissions and supplier data — usually the hardest part of the exercise.
Who it reaches
Scope is phased in over several reporting years, and the detail of which companies are captured — and when — has been subject to ongoing revision at EU level. The practical point for a business outside Europe is that CSRD often arrives indirectly: not as a legal obligation on you, but as a customer asking for data because they are obliged to report it.
What to do about it
The preparation that matters is not framework-specific. Know your organisational boundary. Measure Scope 1, 2 and 3 on a consistent basis. Record the source, factor and method behind every figure so it can be checked later. An emissions number that can be traced and explained will serve CSRD, and it will serve whichever framework asks next.
Reporting rules will keep moving. A governed set of environmental data underneath them will not have to.
