Climathon calls on cities to take part in historic 24 hours of climate action

Cities around the world can join the Climathon movement and take part in a 24-hour global hackathon to find solutions to city climate challenges.

Organised by Climate-KIC, Climathon brings together the challenges of the world’s cities with the people who have the passion and ability to solve them.

The 2017 edition of the global 24-hour climate change hackathon takes place simultaneously in major cities around the world on 27 October and is set to be the biggest event of its kind in history.

Representatives of startup incubators, city hall, local businesses, universities or other organisations can register to be the host for their city via the Climathon website and receive a detailed guide on how to organise the hackathon.

A new generation of entrepreneurs

Since 2015, students, entrepreneurs, big thinkers, technical experts and app developers around the world have been taking action as part of the global Climathon movement by coming up with innovative solutions to city climate challenges in 24-hour marathon sessions.

Tibor Navracsics, European Commissioner for Education, Culture, Youth and Sport, responsible for the EIT, said: “Young people have a vital role in tackling global challenges such as climate change. We need to ensure they can participate fully in making the change Europe needs. With this in mind, the EIT’s Climate-KIC Climathon can make a big contribution to training a new generation of entrepreneurs and innovators.”

The most pressing issues of our time

To take part in the 24-hour Climathon, each city sets its own climate challenge which reflects what is affecting their urban life the most. Challenges vary from air quality, mobility, water and waste management, and extreme weather events. 

Innovators tackle the climate challenge for a full 24-hours, before pitching their ideas in front of a local jury. These ideas can develop into tangible sustainable solutions and businesses that address city climate challenges across the globe.

“The science of climate change is indisputable, but the problem often seems so removed from everyday reality that organisations have for many years struggled to engage citizens,” said Ebrahim Mohamed, Director of Education at Climate-KIC.

“The Climathon changes this, providing the critical impetus for city citizens, innovators, business experts and policy makers to come together in a global climate movement to solve one of the most pressing issues of our time,” Mohamed said.

City-level action at speed and scale

City-level action to address climate change is needed at speed and scale. Cities already contribute over 70 per cent of global carbon emissions and are rapidly growing, with 70 per cent of the world’s population expected to live in cities by 2050.

Now its third year of operation, the Climathon movement has grown tremendously over the past two years, encouraging more innovators across the globe to drive climate action.

Climathon has grown from 19 to 59 cities in the space of a year, operating across 6 continents, creating over 2330 ideas and reaching 16.8 million people worldwide in 2016.
