SuCCESs (Sustainable Climate Change mitigation strategies in Energy–land–material Systems) is a model that represents energy, materials, land use, and climate change globally and can be used to calculate long-term scenarios of these systems up to year 2100. It provides a new way to model how these systems interact and how they could work together towards reaching global sustainability targets, for example, to mitigate climate change. This paper describes how the model works and the results it can produce and how these compare to results from other models.
