We define a science-based net-zero roadmap for the 4RIs.

This roadmap serves as a lighthouse project and a blueprint for other institutions, public entities, and companies.

A working group comprised of researchers, sustainability officers, and members of the operations/infrastructure management from each institute has come together to enable an efficient inter-institutional and cross-disciplinary exchange. The goal of this collaboration is to define the institutions’ pathways to net-zero and the appropriate methodology to track progress.

At the outset, the group collects data to capture the current status and defines the target status for each institution. The development of the roadmap involves considerations about the necessary measures to take and their impacts, looking at various energy scenarios with cost developments, and performing investment cost calculations.

The group looks for synergies with the Research and Technology Transfer Platforms (RTTPs) at Empa, PSI and Eawag including NEST, the Energy Hub, ESI, and the Water Hub.

As a main outcome, a science-based roadmap towards net-zero will lay the basis for internal consensus and the necessary decisions.

The goals of this Priority Action Area include development of the following:

  • Description of the common methodology to develop the Net-Zero Institute Roadmaps.
  • Report on consolidated energy system scenarios describing possible cost trajectories.
  • Roadmap describing the preferred Net-Zero pathway for each of the following institutes: PSI, Empa, WSL and Eawag.
