NRP 73 Project "Post-Fossil Cities"

The postfossilCities simulation game was developed in the context of the "post-fossil cities" project funded by the National Research Programme 73 "Sustainable economy" (NRP 73). The project started in January 2018 and ran until summer 2022.

The project was conducted at Empa, in close collaboration with:

  • Norwegian University of Science and Technology
  • University of Zurich
  • UCS Ulrich Creative Simulations
  • University of Applied Sciences of Eastern Switzerland (OST)

Research activities were mainly conducted by two PhD students and a postdoctoral researcher.
