Innovation, Connections and Fresh Air
34 screens across 21 shopping malls, a shared vision and a wealth of innovative ideas: On 17 September 2026, Impact Innovation Day at Impact Hub Leipzig brought together people committed to driving sustainable change in business and society. As a long-standing partner and supporter, Green City Solutions took part and helped raise awareness of the event beforehand through sustainable out-of-home advertising.
Impact Innovation Day: Where Ideas Meet Change
How can we combine business success with environmental and social responsibility? What innovations do we need to build a sustainable future? And what role do strong networks play?
This year’s Impact Innovation Day at Impact Hub Leipzig explored these questions and more. The sold-out event brought together representatives from SMEs, start-ups, civil society and public administration to develop fresh perspectives, exchange knowledge and work together to advance solutions.

The programme focused on three key themes:
- Wellbeing & Motivation: Putting people first and exploring new approaches to creating a healthy, motivating workplace.
- Entrepreneurship & Organisation: Developing environmentally responsible innovations and promoting sustainable business practices.
- Transformation & the Future: Taking an active role in shaping change and preparing for tomorrow’s challenges.
In 2026, Michael Fritz, co-founder of Viva con Agua, opened the event. Drawing on examples from his work, he demonstrated how social engagement and business success can go hand in hand. Further talks, workshops and personal conversations created opportunities for new ideas and valuable connections.
The day highlighted a clear message: sustainable transformation happens when people come together, share knowledge and take collective action.
Sustainable Out-of-Home Advertising: climAD Raises Awareness of Impact Innovation Day
ven before the event began, Green City Solutions demonstrated its commitment to sustainable innovation. Through climAD, our climate-friendly advertising network, we supported Impact Innovation Day with a nationwide advertising campaign.
The event was promoted on 34 CityBreeze screens across 21 Shopping Malls. What made this campaign different? The digital advertising displays not only attracted attention but also contributed to better air quality.

Our CityBreeze combines digital out-of-home advertising with innovative moss filter technology. A 75-inch screen on the front provides space for digital advertising messages. On the back, a green, revitalising moss wall removes particulate matter from the air flowing through it and provides a natural cooling effect.
This turns conventional out-of-home advertising into a solution with added environmental value.
The campaign also generated enthusiasm at Impact Hub Leipzig. Anja Hirschfelder commented on the collaboration on LinkedIn:
The campaign demonstrated how high-reach communication and sustainable action can work together. It also highlighted the potential of innovative advertising formats to raise awareness of socially relevant issues.
Achieving More Together: Our Partnership with Impact Hub Leipzig
The relationship between Green City Solutions and Impact Hub Leipzig extends well beyond supporting a single event. As a member of the network, we have maintained a close partnership for many years, built on mutual support, shared values and a commitment to positive change.
For our founder and CEO, Peter Sänger, who attended Impact Innovation Day in person, this exchange is an important part of successful entrepreneurship. Sustainable innovation requires more than good ideas: it also needs people and organisations working together to put those ideas into practice.
In a sense, CityBreeze was “part of the action” not only in the lead-up to the event but also during the event itself. Attendees could experience first-hand how sustainable out-of-home advertising and innovative moss filter technology work together.
The Impact Innovation Day campaign also demonstrated the value of this collaboration. It grew directly out of the existing network and turned mutual support into something tangible.
Martin Stöhr, Managing Director of Impact Hub Leipzig, expressed his enthusiasm for the collaboration on LinkedIn: “I’ve been a fanboy since 2014, and I never imagined I’d one day get to become a customer myself.”
Partnerships like this demonstrate the importance of strong networks in driving sustainable transformation. When companies share their expertise, resources and reach, they create new opportunities to make a greater impact together.
After the event, the Impact Hub Leipzig organising team asummed up the atmosphere perfectly: “Community may not be everything, but without community, everything is nothing.”
This idea is central to our work at Green City Solutions, too. With our innovative moss-based biofilters, we work to measurably improve air quality and the quality of time spent in urban spaces. But sustainable urban development cannot happen in isolation. It requires committed businesses, bold decision-makers and strong partnerships.
Impact Innovation Day once again showed what can emerge when people with different perspectives come together around a shared vision.
Thank You for an Inspiring Impact Innovation Day!
“You made it what it was. Thank you to everyone who joined us!” – we wholeheartedly echo this message of thanks from Impact Hub Leipzig. We would like to thank the entire Impact Hub Leipzig team for organising the event, for their trust and for our long-standing partnership. Our thanks also go to all the speakers, supporters and participants who made Impact Innovation Day 2026 such a special experience.
We look forward to continuing our collaboration, advancing new ideas together and making the future a little greener.
