Climate Mitigation from Circular and Sharing Economy in the Buildings Sector

Circular and sharing economy (C&SE) strategies in the building sector offer significant potential for climate mitigation but they remain underexploited. This editorial introduces nine papers of the Virtual Special Issue (VSI) Climate Mitigation from Circular and Sharing Economy in the Buildings Sector that cover a range of related topics. Three of the papers focus on concrete, including modelling current and future quantities, and assessing the impacts of reuse and recycling. Four of the papers focus on waste recovery, including construction waste, wood waste for bio-concrete, urban mining (350 components) and building facades. The papers use a broad set of quantitative and qualitative methods, with a predominance of life cycle approaches but also building models, material flows, scenarios, surveys and interviews. The geographic scope of the studies covers Europe, North and South America.
