Join the Climathon movement and solve the toughest climate challenge cities face today

Climate change is a daunting global challenge.

Thousands around the world see Climathon as a powerful tool to mobilise cities, citizens and local economies to combat climate change. In order to create (some) order in that chaos and have the maximum possible global impact, each city has its own local organizers. In Basel, this is the Department for Environment and Energy Canton of Basel-City, IWB and Impact Hub Basel. So take action and help solve our local climate challenges in the areas of Food, Mobility and Energy.


Setting the climate challenge:
Cities identify their climate challenges, which can be anything from urban mobility to energy, and call on entrepreneurs, students, developers, and more to come up with innovative solutions.

Coming up with solutions:
You’ll connect with city officials and partners to bring about a shared vision for a healthier city. You’ll help turn this vision into a reality by participating in the 24-hour hackathon, where you’ll form teams to find innovative city solutions and win support.

Beyond the hackathon:
You can continue working on your solutions to create tangible change in your city and advance the movement!


  • Take meaningful climate action in Basel
  • Turn your climate solution into a business – and get support
  • Meet like-minded people and become part of the Climathon movement
  • Share your climate opinions and solutions with a global audience

About EIT Climate-KIC

EIT Climate-KIC is a European knowledge and innovation community, working to accelerate the transition to a zero-carbon economy. Supported by the European Institute of Innovation and Technology, we identify and support innovation that helps society mitigate and adapt to climate change. We believe that a decarbonised, sustainable economy is not only necessary to prevent catastrophic climate change, but presents a wealth of opportunities for business and society.

Background of the Climathon 2018

Climathon is a is a global movement dedicated to solving the toughest climate challenges cities face, which is manifested in a 24-hour hackathon which took place simultaneously in 113 cities, 46 countries, and across 6 continents on 26 October 2018. Climathon attracted over 5000 entrepreneurs, developers, students and professionals to work on new, creative solutions to local climate change challenges. Across the world participants tackled 196 climate challenges and 19% were focused around mobility, 15% waste management, 10% climate change (reducing environmental impacts, emergencies, floods, biodiversity) and 10% energy. Solutions to the climate challenges from all over the world are being collected on the Climathon website.

The European Covenant of Mayors partnered with Climathon and invited all the municipalities of their community to join this global movement. In the month of October Climathon had a potential reach figure of 156 million potential viewers (covers all forms of media – online press, website and social media). Since January 2018 Climathon has been featured in 851 articles across the world. On Instagram and Twitter 17,640 posts related to Climathon have been published and featured high profile endorsers such as Ellen MacArthur, Katharine Hayhoe, Caroline Gleich, and UNFCC. A mainstage event in Turin, Italy acted as a connection point for all Climathon events running across the globe. This event was supported by the City of Turin. Live broadcasting sessions from Turin were viewed by 279,848 people, had a reach of almost 600,000 on Facebook and included speakers such as Paola Maugeri, Writer/TV journalist, Marco Cattaneo, Editor in chief of National Geographic Italia, Stefano Boeri, Architect and Pietro Leeman, famous vegetarian Chef.

Challenges for the Climathon 2018

The 196 climate challenges prepared by cities across the world focused mainly on mobility and waste management. Most challenges about mobility aim to solve the problem of private vehicles, improve public transport and reduce traffic in cities. Similarly, challenges about waste management focus on reducing plastics, solid waste and eliminating landfills.

Most of the challenges about energy focus on renewable energies, improve building efficiency, create new heating systems and decentralize energy systems. In the case of nature-based solutions cities focus on improving and developing green spaces and reduce heat island effects. Challenges on circular economy focus on food waste and the reduction of plastic and the elimination of landfills as well.

The main levers of change are related to citizens participation (incl. young people and inclusion), technology, behaviour (incl. culture and mindset), data and awareness. Most cities consider that the combination of many of these levers is the key of success to drive change.

Key findings

  • Most cities consider that city air pollution is caused by their dysfunctional and unsustainable transportation modes. Air quality depends on sustainable mobility.
  • Most of the cities with rivers and channels are exploring options to improve water mobility. Additionally, cities with ports are facing similar challenges.
  • Most of the cities require to build capacities (raising awareness) and preparing projects, plans, strategies. Only few are asking for implementing actions.
  • Cities in the Global South and some European countries in the south of Europe are feeling the impacts of climate change more strongly and they are worried about having to deal with the emergencies. The priorities are different in each continent. However, in general the productivity of agricultural fields is being globally affected.
