Countdown to the Climathon

What is climathon about?

We want to not just talk about sustainability but try to see what technology can do to fight climate change. That is why Hackerstolz and the City of Mannheim are hosting the Climathon. The Climathon is an over regional initiative by the Climate-KIC from EIT that take place in hundreds of cities all over the world. Become part of it! For 40 hours you have the opportunity to develop prototypes for digital solutions together in a team. We provide you with public and non-public environmental data as well as data from the economy, with which you can develop innovative green solutions.

Throughout the entire hackathon, you will be supported by a team of experts who will help you develop your ideas.


Here you find a list of all challenges. Why is this important? At the Climathon you have to decide as a team for ONE CHALLENGE on which you want to work and at the end submit your solution. Only in a few exceptions where it makes sense, a solution for two challenges can be offered.

Technologies & Data

Here you find a list of technologies and data sets which will be provide. Have fun!

Programmers who turn thoughts into code. Only the input speed of your keyboard sets you limits.


With a deep scientific background you build the complex engine room of any technical project.

You and data, it’s a long story. A mixture of data magic and a touch of AI.


Loves tinkering around with hardware and IoT. Your hands start to itch when you hear a great idea.

Idea Generator

You spark creation with your original ideas and understand the problem at hand.


Not techie or a designer, but your magic touch will bring projects to life.


In your skillful hands, dashboards and applications gain clarity and style.

Teams of 3 to 7 people work together on a project idea.

If you don’t have a complete team yet, don’t worry, you can register as an individual participant in the application process and then find teammates before the event in our slack community or during the first day.

So that you have a contact person ready to answer questions on a wide variety of topics, we will put a battalion of mentors at your side. Find out more soon who you can expect here. Would you like to support yourself as a mentor? With pleasure, here you get more information - or you register directly via this form.



Make a difference, with your sponsoring you support promising projects or even startups which aim to save our planet – what else could you wish for? Not enough, as you wish, here some more arguments for you: You are mentioned at the event and on social media. Establish your company as a relevant and sustainable tech player in the dynamic coding community. And beside that you can provide your own challenge and prize depending on the sponsoring package of your choice. Benefit from the inventiveness of the teams working on your challenge. Act now and contact us!

It is difficult to establish a clear and quantifiable criterion as to which sustainability criteria a sponsor must meet. Therefore, we will review different sources to get an idea of how sustainable a sponsor is. These criteria include: The last sustainability report, ISO-50001 certification, published climate indicators such as the X-Degree-Compatibility (XDC), rating in the CDP Climate Scoring etc., are all relevant criteria. If we have the impression that a sponsor does not meet our sustainability expectations, we can reject the sponsor.


You can’t support us financially? No problem, help us to promote the event, become a network and media partner or support us with an immaterial contribution like mentors for the teams, etc. Contact us!
