With growing concerns about the impact of the climate crisis on the
environment and life as we know it, researchers are increasing efforts in
understanding and reducing the environmental impact of basic science research.
Within this context, the proposed next generation of the ISIS Neutron and Muon
Source, called "ISIS-II", is currently being modelled to determine its full
lifetime environmental impact. In addition, a Life Cycle Assessment (LCA)
methodology will be used to compare various design options of ISIS-II with the
view to inform future decisions. In this talk I will introduce the proposed
ISIS-II facility, present the methodology of these impact studies, and discuss
their progress
