What is Climathon


Climathon is a global 24-hour climate change hackathon which takes place simultaneously in major cities around the world each October.

It brings together the challenges of the world’s cities with the people who have the passion and ability to solve them.


Climathon attracts innovators, entrepreneurs, students and professionals to create innovative solutions to cities climate challenges.

In cities with a 24 hour Climathon event, a Young Climathon can be set up for undergraduate students with a related challenge but with shorter time frame.


The Climathon movement has grown exponentially since it began, encouraging more innovators across the globe to drive climate action.

Climathons are now held in over 100 cities, across 45 countries on 6 continents, engaging with over 4400 participants worldwide in 2017 developing over 624 ideas.

How Climathon works

Each city sets its own local climate challenge that reflects what affects their urban life the most.

Participants then tackle the set challenge for a full 24-hours, before pitching their ideas in front of relevant local stakeholders.

These ideas can develop into tangible sustainable solutions and businesses that address city climate challenges across the globe.

“The global Climathon is an ideal opportunity for innovation groups across Australia to showcase their ideas and entrepreneurial skills. The winners in each city will be offered the opportunity to join the unique Climate-KIC Australia pipeline of innovation activities and help provide the ideation for climate solutions that create jobs and growth.”

– Dr Jemma Green, Co-founder Power Ledger, Chair Climate-KIC Australia
