Sustainability

Sustainability consulting and assurance for your company

Our sustainability services include consultancy and assurance work. We support you in embedding sustainability within your organisation and in preparing and auditing your sustainability reports. Implementing effective sustainability management, ESG risk management, ESG compliance and ESG reporting helps you minimise risks across your value chain and create transparency to support long-term business success. Our expert team helps you develop a forward-looking sustainability strategy. At the same time, we help you to identify and mitigate risks in your own operations and supply chain at an early stage. 

We also support the preparation and audit of your sustainability reports to help you avoid greenwashing risks. When doing so, we take into account regulatory requirements such as the Corporate Sustainability Reporting Directive (CSRD), the European Sustainability Reporting Standards (ESRS), the EU taxonomy, the German Supply Chain Due Diligence Act (LkSG), the German Packaging Act (VerpackG) and the German Single-Use Plastics Fund Act (EWKFondsG).
