What a festival edition was
Four things under one roof, every year, for seven years.
Conference
The Green Leaders Conference, later multi-stage programmes: 350 speakers at the 2024 peak.
Exhibition
From 60 exhibitors at Tempelhof to 200 at Messe Berlin.
GREEN AWARDS
The annual gala, running since 2008. The festival grew around it.
Music and culture
Green Vibes, the climate-neutral concert, GTF MUSIC: Nena to The BossHoss.
What the festival becomes
The mass-market format was retired by its own founders in 2025: relevance beats reach. What carries the name forward is the year-round network, the annual GREEN AWARDS, and curated GTF Connect editions of 400+ participants each.
