The circular economy (CE) has attracted considerable focus in recent years for its potential to address sustainability challenges (Stahel, 2016; Korhonen et al., 2018). The idea is to replace the traditional linear economic model of production-consumption-disposal with a circular model of production-use-reuse-recycling (Mhatre et al. 2021). According to Knäble et al. (2022), CE hat the potential to foster sustainable development from a macroeconomic perspective by generating higher GDP, reducing greenhouse gas emissions and lowering unemployment rates at the country level.Findings by Knäble et al. (2022) highlight the potential of renewable energies to reduce greenhouse gas emissions and the unemployment rate, as well as possible spill-over effects that the use of renewable energies can have on other CE value sources. A renewable energy source that has received comparatively little attention is geothermal energy. Geothermal energy is a form of renewable energy that harnesses the heat from the Earth's core to generate electricity. The source is a promising solution to achieving sustainable development goals, including reducing greenhouse gas emissions and increasing access to reliable and affordable energy. The aim of this review is to include all articles and reviews on the topics of CE and geothermal energy and to present a comprehensive analysis of their relation. Therefore, we examine the scientific relevance of geothermal energy in the context of the circular economy. We follow the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) by systematically reviewing and analysing existing scientific articles on the bibliographic database Scopus.
