“…The main barriers are the lack of a solid database solution on availability (i.e., one-stop platform of reclaimed building materials), accessibility (i.e., open access if applicable), interoperability (i.e., secure and efficient data exchange), and user-friendly interfaces for a vast array of users. The different actors involved in circular cities do not have an equal set of skills, information, users, and collaboration requirements . Hence, we highlight the need for transdisciplinary and multiscalar frameworks to enable information sharing .…”

City and regional planners have recently started exploring a circular approach to urban development. Meanwhile, industrial ecologists have been designing and refining methodologies to quantify and locate material flows and stocks within systems. This Perspective explores to which extent material stock studies can contribute to urban circularity, focusing on the built environment. We conducted a critical literature review of material stock studies that claim they contribute to circular cities. We classified each article according to a matrix we developed leveraging existing circular built environment frameworks of urban planning, architecture, and civil engineering and included the terminology of material stock studies. We found that, out of 271 studies, only 132 provided information that could be relevant to the implementation of circular cities, albeit to vastly different degrees of effectiveness. Of these 132, only 26 reported their results in a spatially explicit manner, which is fundamental to the effective actuation of circular city strategies. We argue that future research should strive to provide spatial data, avoid being siloed, and increase engagement with other sociopolitical fields to address the different needs of the relevant stakeholders for urban circularity.

“…There is evidence that recycled construction and demolition (C&D) waste products are technically feasible [6] and regulated in the construction sector [7]. However, there is strong resistance to the reuse and recycling of C&D waste in construction projects [8,9], while poor information is available on who can influence the decision to use recycled or reused products in the sector [10]. There is currently insufficient information and little empirical evidence on the behavior and preferences of consumers and other stakeholders in the use of CE practices, both in buildings and in offshore RES energy production [11], and there is a need to assess their influence.…”

Linear climate mitigation models look into aggregated economic sectors and model greenhouse gas (GHG) emissions disregarding downstream value chains, making particular sectors accountable for downstream (or upstream) GHG emissions. Hence, the present climate mitigation models inconsistently account for indirect GHG emissions; underrepresent upstream and downstream value chains; do not address Circular Economy (CE) practices; do not cover resource consumption, thus not considering materials’ circularity. To provide curated policy support for decision-making for carbon neutrality and other Sustainable Development Goals (SDGs), models need to shift from linear to circular. To achieve this, a link between energy-climate mitigation modelling and cradle-to-cradle assessment CE analytical tools must be established. This is the core issue covered in the CO2NSTRUCT Horizon project (2022-2026). CO2NSTRUCT proposes a framework to supplement the well-established JRC-EU-TIMES model, using a highly comprehensive technological representation with CE measures. The framework will apply CE measures to the value chain of six carbon-intensive construction materials (i.e., cement, steel, brick, glass, wood, and insulation materials) and will provide new components to the JRC-EU-TIMES model, including citizen behaviour; societal impacts; rebound effects; supply and value chains. The results will be used for policy approaches integrating CE into climate change mitigation actions.

“…Currently, the circular economy practices in the building sector have three main focal point arguments; waste management and valorization [58,59]; reversible building design concept [60,61]; green deal within the building sector value chain, and business and stakeholder networks [62,63]. However, the current approach to the circular economy in the building sector still faces barriers blocking the proper conditions from stakeholders to integrate the circular economy in the building sector [64,65]. The barriers emerge from six main groups, namely: environmental, economic, social, organizational, technical, and regulatory barriers.…”

Circularity as a Climate Change Mitigation Strategy in the Building Sector: The Stakeholder’s Involvement in the Interconnected Life Cycle Phases

There is an evident relationship between climate change and the building sector through reciprocal environmental impacts. The circular economy is fitted into this relationship as a mitigation strategy in the building sector, thanks to its nature of life cycle perspective consideration, support for stakeholder collaboration, and the ideology of waste minimization, reduction of natural resource consumption, and greenhouse gas emissions. This article aims to conduct two subsequential systematic literature reviews to evaluate the status in the scientific literature about the circular economy as a climate change mitigation strategy in the building sector and to find the place taken in the scientific literature about the stakeholder’s involvement toward circularity transition in the abovementioned link. As a result of the methodological approach, publicly available and reliable publications have been identified and analyzed based on the publication year and territory. The results indicate an increasing scientific literature contribution about the context, but the stakeholder concept is considerably taken less place; thus, it is a gap in the scientific literature. The stakeholder focal point, which the innovativeness of this article lays down, needs more attention in academic research, thus in the sector with the strengthening collaboration and mutual awareness among stakeholders.
