In 2025, Ecologic Institute marks an important milestone: 30 years of independent environmental research and policy engagement. On 30 June 2025, we gathered with our community of alumni, colleagues, funders, partners, and friends in Berlin to celebrate this special occasion.

The event offered a glimpse into the diverse and international team behind the Institute and reflected on the stories, images, and achievements of current and former staff who have helped shape its identity over the past three decades.

A highlight of the evening was the keynote speech by special guest Sébastien Treyer, Executive Director of the Institute for Sustainable Development and International Relations (IDDRI). He focused on current challenges and opportunities for environmental research and policy – from Europe’s role in driving sustainability to the importance of scientific expertise in a shifting political landscape.

The evening was hosted by team members Matthias Duwe and Ewa Iwaszuk, with live music provided by the band GlasBlasSing. But the anniversary was more than a celebration – it was a moment to reflect, show appreciation, and look ahead. As Director Christoph Heinrich summed it up:

“30 years of Ecologic Institute – It was a wonderful summer celebration with partners and friends. A moment of pride in what has been achieved, a touch of nostalgia, and optimism for the future!” 

We would like to express our heartfelt thanks to everyone who joined us for this memorable occasion!
