Hackathon 2022

Digital solutions for societal challenges – Vienna Climate Challenge

After organising Hackathons as part of the WTZ-Ost (Knowledge Transfer Center East), resulting in fantastic, innovative, digital solutions for current societal challenges, we are happy to announce the date of the upcoming event.

19-21 September 2022

We will start on 19 September 2022 at 15:30 and will end with drinks and snacks on 21 September at 18:00.

Aula, Campus of the University of Vienna (Spitalgasse 2, 1090 Vienna, Austria)

The Hackathon is a physical event, you need to be on site.

Take a look at the agenda-draft here.

  • Are you interested in sustainable innovations?
  • Do you want to work in interdisciplinary teams?
  • Do you want to develop ideas to improve living conditions in sustainable cities and communities?
  • Do you want to apply your theoretical knowledge to the development of solutions for current societal challenges?

All-female teams

In cooperation with She.Digital Wien and DigitalCity.Wien, we would like to additionally address young women to participate in this hackathon and form all-female teams with other researchers/students, to present their ideas and innovative solutions and thus to be a role model for younger female talents! The all-female winning team of the Hackathon 2022 will receive the opportunity to present their successful idea at the #DIDAYS22 event at Impact Hub Vienna as well as other events and digital communication channels of DigitalCity.Wien. 


The Hackathon is organised by the University of Vienna, together with the City of Vienna. Climate change imposes major challenges, especially for cities. The City of Vienna defines concrete goals and measures for the city’s climate package, this is where the Hackathon wants to pick up. Interdisciplinary teams will work on concepts for (participatory) digital solutions to current challenges faced by the City of Vienna on climate. Therefore on one hand challenges were framed that lead to a very specific outcome. On the other hand we present more open challenges, that raise issues, demanding creative solutions.

Background information can be found here:

The challenges concern the climate topics: climate-friendly neighborhoods, energy, circular economy and climate-appropriate behavior.
