ESG reporting requirements: Who must report and when?
The ESG reporting obligation is the statutory requirement for companies to disclose data regarding their sustainability performance on a regular basis. The European CSRD regulates this mandate, placing sustainability reporting on an equal legal footing with traditional financial reporting.
The Indirect Obligation for German SMEs
Many SME owners believe they are exempt from the CSRD. However, a de facto reporting obligation exists due to market pressure:
Banks: Credit institutions must optimise their Green Asset Ratio and prefer companies that provide validated ESG data. A lack of ESG reporting can lead to classification as a high-risk debtor.
Major Customers: Companies subject to CSRD must disclose Scope 3 emissions and pass this requirement on contractually to suppliers.
What Must Be Reported?
The ESG reporting follows the ESRS standards based on the principle of double materiality:
Inside-Out: How the company impacts people and the environment
Outside-In: How climate change and social factors impact business performance
For SMEs not directly subject to the CSRD, EFRAG has developed the VSME standard — a simplified framework designed to be manageable for medium-sized enterprises.
Why Voluntary ESG Reporting Makes Business Sense
Rather than being viewed as a bureaucratic burden, strategic ESG reporting should be leveraged as a competitive advantage when implemented systematically for corporate sustainability.
