GreenHack 2026 is a 24-hour hackathon exploring the intersection of artificial intelligence and sustainability. Under the theme “AI and Sustainability: Friend or Foe?”, the event brings together hackers, developers, designers, data minds, students, innovators and sustainability enthusiasts to work on real-world challenges from partners.

The 6th edition of GreenHack takes place on 5–6 June 2026 at 42 Prague. Participants can join individually or in teams of 2–4 people, build a team on the spot, develop practical solutions, meet mentors, and compete for €4,000 + additional partner prizes.

GreenHack is not about greenwashing. It is about real builds, real data, real impact — and testing whether AI can become a useful sidekick for a more sustainable future. Registration is required at www.greenhack.eu
