31 August & 1 September 2021 | online


Cities are responsible for 70% of the planet’s carbon dioxide emissions. Therefore, they play a central role when it comes to efforts on global decarbonisation and pushing forward the local energy transition. In the lead-up to the global climate conference COP26 in Glasgow, a two-day hackathon will bring together young talents from Switzerland and the UK. The Energy & Climate Hack is part of the Decarbonising Cities conference and will be held entirely in English.

Be part of the hackathon and accelerate the change towards energy-efficient and climate-friendly cities!

Two exciting, exhausting and challenging days await you! Together, we will develop innovative solutions for decarbonising the future of our cities, thinking about renewable energy production, climate monitoring, sustainable innovation, smart cities and more!

In cooperation with the challengers we are preparing exciting topics and datasets for you, just waiting to spark innovative solutions. On the first day of the hackathon, you will be able to choose the challenge team that you want to join.

Of course, there will also be plenty of brainfood, exciting datasets, a motivated crowd and diverse know-how and knowledge from all around the world, especially from the UK and Switzerland!




Due to travelling restrictions in times of COVID19, the hackathon will take place online. You will receive event details in your confirmation mail.




The ENERGY & CLIMATE HACK is open to anyone interested to think creatively, design, and crunch data around energy, cities, mobility… We are particularly inviting students in software development, design, data science and analytics, but also urban planning, architecture, sociology, engineering, etc... Let us join together and design a decarbonised urban ecosystem.

Participation and catering are free thanks to the support of our partners and sponsors.

All attendees, sponsors, partners, volunteers and staff at our hackathon are required to agree with the Hack Code of Conduct. Organisers will enforce this code throughout the event. We expect cooperation from all participants to ensure a safe environment for everybody.




Together in teams, you will solve tough and exciting challenges about optimising energy resources in all fields of urban life. We will keep you informed as we upload the challenges around a month before the event.

Topics of the hackathon challenges:

  • Solar panel detection
  • Co2 reduction of data centers
  • Designing a tool for sustainable innovation in companies
  • Vertical farming
  • Regenerative Finance for Smart Energy Communities
  • Heat monitoring networks
  • Creating data-driven building models
