CSRD Reporting: A Practical Guide for SMEs

The Corporate Sustainability Reporting Directive (CSRD) brings a much wider set of companies into mandatory sustainability reporting under the European Sustainability Reporting Standards (ESRS).

Who is in scope

CSRD applies to large EU companies, listed SMEs (with simplified standards) and certain non-EU groups with significant EU activity. Many SMEs are also affected indirectly, as larger customers request ESRS-aligned data through their value chain.

What needs to be reported

Reporting follows the ESRS, which cover environmental, social and governance topics. Companies first carry out a double materiality assessment to identify which topics are material — both in terms of impact on people and the environment and financial relevance to the business — and then report only on those.

Practical steps for SMEs

• Run a double materiality assessment. Identify the ESRS topics that are actually material to your business and your stakeholders.
• Map your data. Locate where the underlying data sits — energy bills, HR records, supplier information — and close the gaps early.
• Use the SME standards. Listed SMEs and the voluntary VSME standard offer a simpler reporting framework than the full ESRS set.
• Anticipate value-chain requests. Even non-listed SMEs are increasingly asked for ESRS-aligned data by larger customers and lenders.

Treat CSRD as a strategic exercise, not a tick-box one. Companies that get their data infrastructure in order now will report faster, with fewer surprises, and use the same data to drive real performance improvements.
