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 Mandate for German SMEs
Many SME owners believe they are exempt from the CSRD. However, market pressure creates a de facto ESG reporting obligation:
Banks: Credit institutions must optimise their Green Asset Ratio and show a clear preference for businesses that provide validated ESG data. A lack of sustainability reporting can lead to classification as a high-risk debtor.
Corporate Customers: Companies subject to the CSRD are required to disclose their Scope 3 emissions, subsequently passing these compliance requirements down the supply chain to their suppliers via contractual obligations.
What Needs to Be Disclosed in ESG Reporting?
The sustainability report must comply with the ESRS standards, applying the principle of double materiality:
Inside-Out Perspective: The impact of the company's operations on people and the environment
Outside-In Perspective: How climate change and social factors influence business performance and financial materiality
For SMEs not directly scope-bound by the CSRD, EFRAG has developed the Voluntary SME (VSME) standard—a simplified framework tailored to the operational realities of medium-sized enterprises.
Why Voluntary ESG Reporting Makes Strategic Sense
ESG reporting should not be viewed merely as a bureaucratic burden, but as a strategic competitive advantage when implemented systematically.
