Allocation methods for estimating the share of safe operating spaces were based on equal per capita at the national level and final consumption expenditure at the power sector level, respectively. Results of the AESA indicate that WtE-Hyb is the best-performing option among those considered, exerting the least pressure on planetary boundaries.

These emissions exceeded the estimated allowable limits by 8700%, 8400%, and 3100% for the three WtE options, respectively. Despite transgressing six boundaries, WtE-Hyb had the lowest pressure in five of them, except for freshwater eutrophication, where it exerted the second-highest pressure. In contrast, WtE-In transgressed the most boundaries (a total of 10) and exerted the highest pressure across all categories.

With this study, we introduce a novel framework for assessing the urban metabolism and circularity of urban areas to support decision-making within the CE context. The framework integrates a structured dashboard of 27 CE indicators with the urban metabolic life cycle assessment approach (UM-LCA), which couples Material and Energy Flow Analysis (MEFA) with Life Cycle Assessment. We developed this framework building on insights from two prior studies, where we explored the utility of MEFA and UM-LCA as decision-support tools within the CE context, and by identifying CE indicators in the literature based on the RACER (Relevant, Acceptable, Credible, Easy, Robust) criteria. To demonstrate the applicability and utility of the framework and examine its strengths and weaknesses, we applied the framework to the Umeå urban area in Sweden. The application of the framework provided a detailed quantitative analysis of material and energy flows and environmental impacts per sector within the urban area, indicating key sectors in terms of resource use, waste generation and environmental performance. It also provided a comprehensive evaluation of Umeå's current level of CE development, highlighting areas of strength and improvement, and offered a prospective assessment of the environmental implications of potential future circular strategies. Overall, the framework proved to be a valuable tool for generating detailed insights into material and energy flows, environmental impacts and circularity, which can be particularly useful for the design, monitoring and evaluation of urban-level circular strategies.

Existing regulations dictate methods for measuring the greenhouse gas (GHG) emissions from buildings, including specific performance thresholds. Such a narrow focus on reducing GHG emissions neglects impacts on other key planetary boundaries (PB), such as biosphere integrity, and could even lead to an increase in these non-climate impacts. Existing environmental indicators for biosphere integrity, such as the Biodiversity Intactness Index (BII), are not directly operational in LCA, making it difficult to define regulations on environmental disclosures for actors in the building sector and related threshold values. Current LCIA methods used in other sectors aggregate midpoint indicators, such as climate change and land use, into damage to the endpoint indicator ecosystem quality. This endpoint indicator is for example measured in the unit potentially disappeared fraction of species integrated over time (PDF.yr). While this only captures some aspects of biosphere integrity, this paper argues that endpoint damage indicators can be used as a proxy. This study aims to bridge the gap between the PB for biosphere integrity and current LCIA methods by developing a set of conversion factors for three common LCIA methods: ReCiPe 2016, Impact World+ (IW+) and LC-IMPACT, and comparing to one LCIA method with an existing PB link: PB-LCIA. This is accomplished by defining a relationship between the units BII and PDF, based on different land use types defined in the original GLOBIO model underlying the PB. The conversion factors were used to translate the BII boundary value (90 %) to a corresponding boundary value for the respective PDF-based endpoint units of the LCIA indicators of the three methods. Through case studies of five Danish buildings, the results show that the impact on biosphere integrity through the proposed conversion factors highly depends on the chosen LCIA method, with LC-IMPACT systematically estimating the highest impacts. ReCiPe and IW+ show similar results, with ReCiPe estimating 48–63 % and IW+ 55–74 % of LC-IMPACT impacts. Using PB-LCIA results in the lowest level of transgressions of the allocated PB compared to the three other methods, and it demonstrates a greater distinction in results between materials in wood and concrete, indicating higher sensitivity to material choice. In some cases, the disagreement between LCIA methods led to uncertainty on whether the ecosystem damage impacts were below or above the allocated thresholds. Further, a contribution analysis of the life cycle impacts showed that the LCIA methods even identify different hotspots within the case studies. This highlights the need for future research to better understand the reasons for these disagreements across LCIA methods for the development of consistent and robust conversion factors.

This study aims to develop a decision-support model that uncovers hidden systemic interactions among circularity variables. Employing an integrated participatory systems modelling approach, the research combines two analytical methods: cross-impact matrix multiplication applied to classification (MICMAC), which identifies key system variables and evaluates their driving and dependency relationships, and causal loop diagram (CLD), which visualises the feedback loops and interconnections among variables. Expert interviews were conducted during MICMAC analysis and CLD development to identify the relationships between variables and validate the proposed model. MICMAC analysis highlights end-of-life circularity solutions, circular material sourcing, and circular planning as the most dependent variables, while expert involvement, environmental regulations, and government funding emerge as the most influential variables. The CLD analysis reveals the feedback mechanisms and causal linkages, offering a comprehensive understanding of the dynamics that shape material circularity in the construction sector.
