An annual three-day B2B event in Berlin bringing together innovators, corporate leaders, investors, startups, and policymakers to address business sustainability through clean technology, circular economy practices, and net-zero transitions.
The Greentech Festival (GTF) is an annual B2B conference, exhibition, and awards platform held in Berlin, focused on sustainable technologies and business sustainability. It convenes innovators, corporations, investors, startups, and policymakers across renewable energy, clean technology, circular economy, sustainable transport, and AI-driven climate solutions. Now in its 2026 edition, the event combines a conference programme, an exhibition floor, the GREEN AWARDS ceremony, and structured networking formats under a festival framework.
The Greentech Festival positions itself as a multi-format platform where sustainability-focused actors across industry, finance, policy, and technology converge. The event is built around the premise that net-zero and circular economy transitions require collaboration between corporate decision-makers, early-stage startups, regulators, and capital providers. Its three-day format blends large-format conference sessions with smaller roundtables, a curated start-up zone, pitch competitions, and a flagship awards ceremony. The event is conducted in both English and German, reflecting its European base and international audience.
The programme addresses the following thematic areas:
Confirmed sponsors for the 2026 edition include Audi and Vodafone Business, among others listed by the organiser.
Handelsblatt serves as both an official media partner and a confirmed sponsor of the event, providing editorial coverage oriented toward the German-speaking business audience.
