Climathon Helsinki 2026 - After Once

Save the Date: Climathon Helsinki 2026 - After Once. 

What if nothing was single use?

Every day, thousands of products are designed to be used once and discarded. Packaging, takeaway containers, event materials, consumer goods and countless everyday items pass through our hands for only a moment before becoming waste.

But what if we designed our city differently?

Join Climathon Helsinki 2026, a collaborative innovation challenge bringing together students, professionals, entrepreneurs, researchers and city-makers to reimagine a future beyond single-use culture.

Over two days, participants will work in multidisciplinary teams to develop bold, practical solutions that support Helsinki's transition towards a more circular, resource-smart and climate-neutral future.

Whether your background is in business, technology, design, sustainability, engineering, social sciences or something entirely different, your perspective matters.

Save the date: 12–13 October 2026

More information, challenge details and registration will be announced soon.
