Envisioning a More Sustainable Stockholm



Like most cities, Stockholm will in the future need to transition into more sustainable energy sources.

Local energy company, Fortum Värme, has taken on this challenge and are proactively working together with the people of Stockholm to find new ways to make the Swedish capital more sustainable.



In collaboration with growth and innovation company, All Work United, Another Tomorrow facilitated a hackathon during Stockholm Act Festival at beautiful Rosendal Gardens.

The brief for the hackathon revolved around how Fortum Värme, as Stockholm City’s own energy company, can become climate and resource neutral by 2030.

Participants consisted of representatives from Fortum Värme, as well as perspectives from a diverse set industries and organisations who acted as catalysts in the innovation process.


The prototypes from the hackathon were crystallised, live, in animated video format —ready to be actioned by Fortum and put on Fortum Värme’s platform for innovation, Hållbar Värme. Here, the people of Stockholm are invited to join the discussion and can add their perspectives. 

The expert teams developed hundreds of ideas and concepts around sustainability projects for Fortum Värme and the people of Stockholm. And the debate needed to evlolve this area was well and truly sparked.

Cross-functional & cross-disciplinary

Visualizing experience of ideas

The inclusion of outside perspective is vital. To connect with people who have knowledge from sectors that are not biased to what are trying to achieve is what makes a process like this so valuable.
