Abstract: This literature review explores the synergies between circularity and decarbonization principles in the construction sector, focusing on their potential to accelerate the transition to a carbon-neutral future. Through analysis of 61 studies, critical barriers are identified, such as data gaps, insufficient recycling infrastructure, and regulatory fragmentation, that hinder the integration of circular and low-carbon strategies. Regional disparities reveal that developed regions, supported by robust policies and infrastructure, lead in circularity adoption, while developing regions face systemic challenges, including limited material recovery networks and technological barriers. Previous studies have largely examined circularity and decarbonization separately, whereas this review provides a synthesis of their interdependencies, focusing on implementation challenges and regional disparities, highlighting synergetic solutions such as fiscal incentives, material passports and stricter end-of-life waste regulations, biobased and carbon-negative material innovations, and digitalization through tools like Building Information Modeling (BIM) and/or digital twins. However, complexity of circular solutions and lack of interdisciplinary collaboration forms a barrier against integration. This review emphasizes the need for standardized frameworks, cross-sectoral coordination, and targeted investments to ease integration of circularity and decarbonization.
