How is the VSME different from the ESRS?
Short answer: The ESRS include more than 1,000 data points, require a double materiality assessment, and demand detailed value-chain analysis; the VSME is more compact, skips a formal double materiality assessment, and focuses on internal company data[14].
The VSME cuts the reporting scope significantly: around 100 data points are sufficient, while the ESRS prescribe several hundred metrics and also ask in detail about strategies, actions, and targets[11]. A mandatory double materiality assessment (impacts and financial materiality) is required only by the ESRS; in the VSME it is optional, though a simplified version is recommended[15][16]. The ESRS also require full value-chain analysis (upstream and downstream activities), whereas the VSME puts less emphasis on that level of detail and focuses mainly on internal processes[17].
