Sustainable Digital Challenge

3 months to learn key principles and best practices on sustainable design, architecture, and code to develop more sustainable software.

Sustainable Digital Challenge is powered by

APIdays – World’s leading series of API Conferences & Fairness


Build a common open knowledge platform to deconstruct clichés about Digital Sustainability

  • Document what are the actual practices causing the maximum effect on energy consumption
  • Match current eco-design practices benefits with current organizations problematics about digital transformation, by identifying the levers of change internally
  • Identify new practices and engaged actors enabling the sustainable digital ecosystem to grow
  • Communicate wider on making digital technologies sustainable in the developer, architect and designer/product communities and in the tech medias

Apidays is the leading industry tech and business series of conferences in APIs and the programmable economy.


A digital project (cloud or not) on which we will be able to apply the maximum of eco-design


January - March 2020


Multi-disciplinary teams. (designers, architects, developers, product managers)


To learn, to share, to meet the community and (why not) win a prize.

Rules of the Challenge

Each participating team will select one project (new or ongoing).

​Teams will identify and apply markers to optimize environmental impact on their project across:
