ESG reporting rules in the European Union
The EU has the world’s most detailed sustainability reporting rules. The CSRD and ESRS set what in-scope companies report, the CSDDD covers supply chain due diligence, the EU Taxonomy defines sustainable activities, and CBAM puts a carbon price on certain imports. The 2026 Omnibus changes narrowed who has to report and delayed due diligence.
