This online hackathon is organized by the Goethe-Institut together with Scientists4Future Heidelberg and The Hackathon Company. 

Applications are open until October 27th. You may apply and find more information here:

Within 40 hours, you will develop innovative solutions related to climate change topics. These solutions can be apps, games, business plans etc. The best ideas will be awarded after a final pitch. Apart from this problem-solving phase, you have the chance to network and develop further skills in webinars during the event.

You can submit in the following challenges:

Raising awareness
e.g. How can we achieve behavioral changes that support climate protection? (e.g. by nudging) How can we make traveling more eco-friendly?

e.g. How can we communicate climate change to the public in a way that encourages people to take concrete environmental actions? How can we counteract fake news around climate change effectively?

Social perspective
e.g. How can we adapt measures that were developed in the context of the Corona crisis to achieve sustainable climate protection? How can we emphasize the benefits of a reduced digital CO2e footprint?

Big Data
e.g. Which possibilities does big data offer to evaluate climate mitigation measures? How can we enable local authorities to access climate data and to develop solutions that help them overcome risk factors associated with their geographical conditions?


Developers, designers, creative people, scientists, problem solvers, digital entrepreneurs, makers, experts, innovative start-ups - and anyone else over the age of 18 who is a EU- or UK-citizen or resides in an EU or UK country and who wants to contribute and make an impact. Use your teams’ interdisciplinary skills and be creative together to develop solutions that help EU citizens - and everybody else – to tackle The Climate Challenge. We welcome you all!


The solutions have to be submitted in English by 1st November 2020, 13:00 PM CET (end of the hackathon) on DevPost. 

To wrap up the weekend of work, the hackathon will end with the short-listed pitches of your creations. Pitches are composed of two main parts which mostly override one another in the content but have different formats:

Textual Pitch:

The purpose of this is to give the jury an extended understanding of your solution. You may also fill this out in concise bullet points. Composed of 7 points that you should prepare in advance before submitting to DevPost (not more than 1 page /500 words). 

  1. The problem your project solves
  2. The solution you bring to the table (including technical details, architecture, tools used)
  3. What you have accomplished during the weekend
  4. The necessities in order to continue the project
  5. The URL to the prototype [Github, Website,...] (if applicable)
  6. The URL to the pitchvideo (Required)
  7. Pick one speaker who may pitch your project on Sunday and provide his/her name at the end of your textual pitch on Devpost.

Video Pitch:
For the video part, you have two strict requirements:

  • No longer than 2 minutes
  • Uploaded to YouTube as a public video (it can be “unlisted” if you want to)


For the rest, it is up to you, but we recommend structuring the video into 4 parts: the problem, the solution, what you accomplished and finally what you are planning to do next. So you have 2 minutes to cover 4 parts. We suggest dedicating about 30 seconds for each topic, but you are free to be more flexible.
