GreenHack 2025 is the fourth year of international sustainability hackathon tackling environmentally responsible development and future greatest challenges. We are not afraid of the big issues. Climate change, overconsumption, irresponsible production and poor resource management. Let’s take them on.

We are certain that technology, together with our willingness to behave differently, is key to solving 21st century issues. Will you give it a try?

100+ masters of innovation, cutting edge technologies and new materials, product and service design as well as other young experts will compete for great prizes with their solutions for the specific challenges of our partners.

The battle will last two days, non-stop. Dare to join in?
