2026 EU Digital Readiness Guide

Navigating the Convergence of ESEF and CSRD Reporting

Financial and sustainability reporting no longer run on separate tracks. ESEF filings face sharper scrutiny, and CSRD keeps shifting under the Omnibus I package. Teams that manage both through disconnected processes carry the risk twice.

2026 is a hinge year. Investors want connected data across financial and non-financial disclosures. Regulators want that data structured and machine-readable. The question is no longer whether reporting complexity will grow. It is whether your reporting infrastructure is ready for it.

This guide shows where ESEF and CSRD now overlap, where past reporting cycles broke down, and how leading companies build one reporting foundation for both.
