Festival der Taten - The HNEE Sustainability Festival

12 - 14 March 2026 | Waldcampus

The Festival der Taten invites you to shape change in the here and now - through practical action, joint experimentation and formats that make sustainability tangible and accessible.

This website is growing with the festival: in the coming weeks, more content will be added here bit by bit - including impressions, results, information on participants, supporters and much more.

Doing things together: where encounters have an impact

In a time of multiple crises, we need spaces where people not only talk about change, but also shape it together. This is exactly what HNEE's Festival der Taten offers: a place where encounters become the starting point for concrete action.

Climate change has long been a reality. This makes it all the more important to develop solutions together and take action. In March 2026, we are therefore focussing on the value of personal encounters - as a source of strength for joint commitment. In a world full of digital sensory overload, we often lose touch with our own actions. But real encounters connect, encourage, open up perspectives - and make it clear that we can make a difference together.

The festival is more than a traditional conference: it is a hands-on festival that focuses on empowerment, practical relevance and community. In workshops, activities and field trips, people try things out, put them into practice and shape them. In this way, sustainability can be experienced on site - locally, concretely and together.

Under the motto "Doing together - where encounters have an impact", HNEE invites you to get active. Because change begins where people take responsibility, share ideas and act together.

Festival programme

When HNEE won the "National Prize – Education for Sustainable Development" in spring 2023, it was clear that the €10,000 prize money would be invested in an action-oriented sustainability event format. From the outset, it was clear that the content should be designed by the students as the central group of participants. A group of students from the Master's programme in Sustainable Regional Development developed a concept for an event and a prototype. This gave rise to the Festival of Action.

In recent months, numerous committed individuals have responded to our "call for participation" in the festival. The result is a colourful programme that inspires, stimulates reflection and lets actions speak for themselves.

Carla Reemtsma

Carla Reemtsma grew up in Berlin and studied politics and economics in Münster. Inspired by experiences at climate camps around the open-cast mines in the Rhineland lignite mining area and Greta's school strikes, Carla organised the first climate strike in Münster. Since then, Carla has been active in the climate justice movement, organising climate strikes, blocking car shows and open-cast mines, and discussing the phase-out of coal, capitalism and the consequences of climate change with grandparents and politicians alike.
