In the context of achieving a climate-neutral and sustainable electricity system, energy systems modelling is often used as a tool to assist decision making. However, a challenge posed within the field is how to represent sustainability in a way that presents actionable, clear and holistic results. There is thus a need to give a more comprehensive and nuanced view of sustainability aspects of energy system modelling.
To provide a basis of understanding of how sustainability could be conceptualized and assessed in energy systems modelling, six well known (from a Swedish point-of-view) sustainability frameworks were analyzed and presented in this report: the concept of Environmental Carrying Capacity, the Planetary Boundaries, the Doughnut Economics framework, the Sustainable Development Goals, the Swedish Environmental Quality Objectives and the Framework for Strategic Sustainable Development. The frameworks were structured according to their sustainability concept and according to what decision-making they would be able to provide input to. The results of the report serve as input to the discourse concerning how the energy system could be transformed to 100 % renewable electricity production along a truly sustainable way.
