Environmental management systems in transition
A professional event for environmental assessments, audits, and consulting in environmental and sustainability management
On 24th September 2025, VNU invites you to this year’s Environmental Verifier Day in Cologne.
The event is hosted by the German Aerospace Center (DLR), which is celebrating 25 years of active environmental management. VNU is also marking its 25th anniversary, and EMAS (the EU Eco-Management and Audit Scheme) is looking back on 30 years of experience.
As every year, the Environmental Verifier Day offers a valuable opportunity for professional exchange and discussion of current developments in environmental and sustainability management. Once again, the focus will be on practical expertise.
To conclude the day, the DLR invites participants to an exclusive guided tour of its campus.
