The Forum Ecological Sustainability in the Theatre provides stakeholders and institutions within the German-language theatre sector with a space to exchange ideas about sustainable cultural work. Representatives of the theatres and production houses nominated for the festival’s 10 remarkable productions act as Green Ambassadors, taking part in networking events and workshops. They will discuss approaches and challenges of sustainable theatre work together and develop strategies and projects towards ecologically sustainable cultural production.

Within the framework of the 2021 Theatertreffen and in cooperation with the action network  “Nachhaltigkeit in Kultur und Medien”, the project Forum Ecological Sustainability in the Theatre took place for the first time. The aim of this series of events is to actively develop a long-term network for issues of sustainability in the theatre and to connect with already existing initiatives. Theatertreffen would like to serve as a dialogue platform.

Forum Ecological Sustainability in the Theatre 2022

On 6 and 7 October 2022, the autumn workshop of the Forum für Ökologische Nachhaltigkeit im Theater (Forum for Ecological Sustainability in the Theatre) took place with the second group of Green Ambassadors. A total of 17 representatives from the theatres and production houses invited to the Theatertreffen discussed urgent issues of ecological transformation and future viability of the theatre amongst each other and with invited guests.

Topics included systems for environmental management and the freedom of art as well as communication strategies and the exchange of existing knowledge and best practices. As invited guests, alumni of the previous forum, Wiebke Leithner (deputy financial director at Vienna’s Burgtheater) and Sophie Gruber (member of the communication team at Berlin’s HAU Hebbel am Ufer), gave insights into their practices and experiences. Furthermore, Charlotte Sieben (managing director of Kulturveranstaltungen des Bundes in Berlin GmbH, KBB) talked about the EMAS-certification process of KBB and the Green Ambassadors met Hortensia Völckers, Artistic Director of the German Federal Cultural Foundation, for a conversation.

Forum Ecological Sustainability in the Theatre 2021

The first Forum Ecological Sustainability in the Theatre began with a digital launch event on 13 April 2021, attended by delegates from various departments representing eight theatres, production houses and collectives. This was followed by the Forum’s first two-day analogue workshop on 30 September and 1 October 2021 in Berlin: A total of 15 Green Ambassadors exchanged ideas on ecological sustainability in their workplaces and discussed the opportunities and challenges of a theatre made fit for the future.

In conversations and interactive workshop sessions, the participants outlined various options for initiating sustainable transformation processes and developed strategies for implementing sustainability goals for operational structures and theatre productions. They were introduced to the EMAS Eco-Management and Audit Scheme and to the Creative Green Tools Calculator, two tools for sustainability-oriented structuring and accounting for cultural institutions and projects. As guest speakers, Charlotte Sieben, Managing Director of KBB GmbH and Thomas Oberender, Director of Berliner Festspiele, contributed examples and experiences from their own practice.

As a result of their conversations during the workshops, the Green Ambassadors framed a first set of wishes and goals for their own houses and teams, which will be further debated, elaborated and discussed at a digital meeting planned for January 2022. The Green Ambassadors will once again get together in person in the context of the 2022 Theatertreffen, where they will also meet a new generation of Green Ambassadors who will begin the 2nd Forum Ecological Sustainability in the Theatre that year.
