The circular economy model has been proposed as a possible strategy for sustainable development in urban areas, implying that its core principles need to be cascaded down to various sectors, including the energy sector. District heating and cooling systems have great potential to enhance circularity on an urban level due to the establishment of synergies between different sectors, the incorporation of renewable energy sources and high efficiency. Indicator-based frameworks are valuable tools for monitoring the transition toward a circular economy. However, no framework to assess circularity in district heating and cooling systems was found. Thus, this study addresses this gap by reviewing currently available indicators used to assess district heating and cooling systems and understanding to what extent they reflect circular economy principles. For this purpose, 27 papers with 271 indicators were assessed against defined criteria related to the circular economy principles. These criteria included transparency, stakeholder engagement, effective communication, ability to track temporal changes, applicability, alignment with circular economy principles, validity and relevance to sustainable development. Afterwards, 89 indicators were selected and classified based on the 10R principle framework. The assessment revealed that the assessed papers cover a wide range of topics and assessment types and that none of the assessed papers fulfils all of the assessment criteria. Moreover, most of the identified indicators connect to the environmental and economic pillars of sustainable development, and the identified indicators focus primarily on the R principles of Reduce and Recover. This study laid the foundation for further research on the relationship between district heating and cooling systems and the circular economy by identifying the understudied areas and highlighting the need to develop tailored indicators to measure circularity in these systems.
