With more than 14,000 visitors, over 350 speakers across 6 stages, 200 exhibitors, 24 MAIN STAGE sessions, 15 DEEPDIVE sessions, 20 SOLUTION STAGE sessions, 35 E.ON NEW ENERGY STAGE sessions, 6 GREEN BUSINESS BOOTCAMPS, 8 NETWORKING EVENTS, and 12 GUIDED TOURS we are proud to say that the sixth edition of the GREENTECH FESTIVAL in Berlin was an overwhelming success!

We look back on the three fantastic days filled with important ideas and innovations, great discussions, networking, and inspiration for what’s coming next!





At the CONFERENCE from 16-17th of May, 350 speakers presented their future-oriented solutions and ideas across 6 stages, including the E.ON New Energy Stage. The core topics of the CONFERENCE ranged from AI, circularity, HR and leadership, mobility, sustainable buildings, food, agriculture, media and culture, with AI being a recurring focus throughout the proceedings. Here, you can watch the whole panel “AI & Data-driven sustainability: Can we upgrade industry at speed?” focusing on this topic.

Another topic that was in focus at the CONFERENCE this year was Greenwashing, which was discussed in the panel “How do we fight Greenwashing?”, moderated by Céline Flores Willers, Founder & CEO of The People Branding Company. In a collaboration with The People Branding Company, GTF undertook an industry study, the results of which were presented live at our festival.

Our EXHIBITION showcased the innovative diversity of companies of all sizes and from various industries. The newly introduced START-UP LAND offered 50 selected young companies from all over the world a booth sponsored by GTF. This provided them with a platform to present their ideas to a broad audience and attract potential investors as part of the GREEN INVESTORS CRUNCH. Moreover, 18 start-ups got to compete in the heat rounds of our Start-Up Slam, and three lucky finalists had the chance to present their ideas to our full audience on the MAIN STAGE. This year’s winner was the young company Viva Organica from Botswana.


One unique feature of the GREENTECH FESTIVAL is the variety of politicians who participate in the festival’s programme. German politicians such as Franziska Giffey, Ricarda Lang, Daniel Günther, Franziska Brantner, Steffi Lemke, Volker Wissing, and Christian Lindner visited the GTF and spoke about measures for a sustainable future in Germany and beyond.

Sublime Systems is on a mission to have a swift and massive impact on global CO2 emissions by decarbonizing cement. Unlike net zero solutions that rely on carbon capture, Sublime’s fully electrified, “true-zero” approach avoids the industry’s legacy fossil-fueled kilns and CO2-heavy limestone feedstock. The fully electrified electrochemical process produces Sublime Cement™ that meets performance-based standards and works with existing concrete ready-mix. Third party life cycle assessments have shown Sublime’s manufacturing can reduce the global warming potential of cement in the U.S. by over 90%. Learn more through their website sublime-systems.com
