Challenges addressed

Improve citizens’ understanding and participation for advanced democratic decision-making, balancing and enhancing both collective and individual freedoms, in particular towards reaching societal goals of universal human wellbeing within the limits of the biosphere, while respecting human rights, building on the Universal Declaration of Human Rights and the 1993 Vienna Declaration.

Climate crisis, biodiversity loss, growing inequality - Science shows that nothing short of a radical reduction of humanity’s aggregate energy and material metabolism, combined with a complete restructuring of almost every economic activity, to ensure inclusive and universal satisfaction of human needs, will get us where we need to be. Technology will help, but only once we agree on the goal of society, and redefine our common values.


  • Develop a process and tools for a citzens’ assembly scalable to any size.
  • Include academic principles and values in the ACA.
  • Validate the ACA in real-life settings: cities, communes, cantons.
  • Integrate the ACA in the Swiss political landscape.
  • Use the new ACA to engage the Swiss society with climate and biodiversity action, as well as societal wellbeing.

What are the expected outputs of this project?

  • Capacity building/broad learning about major issues of society
  • Timely, better decision-making with limited polarization
  • Enable effective Swiss climate and biodiversity action
  • Improved social cohesion, better empathy
