What is the VSME standard?
The VSME standard (Voluntary Sustainability & Mandatory ESG) offers small and medium-sized enterprises (SMEs) a simplified way of documenting their sustainability performance in a transparent and standardized manner.
Many companies are not (yet) required to report directly under the Corporate Sustainability Reporting Directive (CSRD). Nevertheless, investors, banks and business partners are increasingly demanding ESG transparency. With VSME, SMEs are ideally prepared - regardless of whether they want to report voluntarily or meet future requirements at an early stage.
Why should SMEs start sustainability reporting now?
ESG regulation in Europe is constantly evolving. Despite the current uncertainty caused by the Omnibus Act, the reporting obligation may soon extend to your company.
With VSME you are prepared for future obligations and also benefit from:
- Competitive advantages through transparent sustainability reporting
- Easier access to financing (e.g. sustainable loans, investor expectations)
- Stronger business relationships as you can provide transparent ESG information to customers and partners
