WISTA Conventions is certified as “High Performer” at Sustainable Berlin
The event service in Adlershof clearly positions itself as a sustainable event service
For WISTA Management GmbH, sustainability is not a short-term trend, but an integral part of its corporate practice. This has also been officially confirmed: in December 2025, the Adlershof-based event service provider WISTA Conventions received the Sustainable Berlin certification at the “High Performer” level.
The award recognises the division’s holistic sustainability concept and sends a strong signal for responsible event management in the German capital.
At WISTA Conventions, events are consistently planned and implemented with sustainability in mind. This includes:
- fair supply chains,
- the use of climate-friendly energy,
- effective waste and resource management, and
- social responsibility at the local level.
The approach aims to offer both organisers and guests high-quality and sustainable event formats.
Sustainable Berlin Audit
The certification process began in the summer of 2025 and placed high demands on the entire team. Over several months, all relevant processes were analyzed, further developed, and documented. Project management was handled by a central team, which coordinated the process and implemented the necessary measures together with the responsible departments. The successful certification is the result of intensive cooperation, a high level of commitment, and a clear common goal.
For WISTA Conventions, this certification is not an end point, but a clear incentive. The team intends to continue developing its standards, setting new trends, and continuously improving the quality of sustainable events in Berlin.
Bessie Fischer-Bohn, WISTA authorised signatory and head of Conventions:
‘For WISTA, sustainability is more than just a label—it is our guiding principle. At WISTA Conventions, we take a holistic approach to events: fair supply chains, climate-friendly energy, effective waste and resource management, and social responsibility on site. The fact that we achieved the “High Performer” level of Sustainable Berlin certification in December 2025 confirms this approach and motivates us to continuously improve quality for event organizers and guests in Berlin.’
