This paper is the first in-depth review of the state of the art of environmental impact indicators for adaptive reuse of cultural heritage (ARCH) buildings from a circular economy perspective. Buildings are a necessary component of sustainability planning because they are significant consumers of natural resources, producers of construction and demolition waste, and contributors to greenhouse gas emissions. In addition, buildings, particularly ARCH buildings, are long lasting; therefore, measuring and managing their environmental impacts is crucial to achieving the universal vision of a sustainable, low-carbon economy. The research answers the questions, 'What are the environmental impact indicators used by individual ARCH building project analyses?' and 'Are the most commonly used indicators reflecting Circular Economy concepts?' It synthesizes and defines current practice in the field whilst highlighting the gaps between practice and policy. Although the term 'Circular Economy' is not explicitly and routinely used in the literature, related concepts such as life cycle analysis, energy consumption reduction, energy efficiency, and embodied carbon/energy are evident at the project level. Concrete and measured environmental indicators are not mainstream. However, narratives of environmental protection feature prominently in the literature, indicating an environmental motivation for repurposing cultural heritage buildings. Further, there is a gap between common indicators of circularity and the ARCH building project level indicators shown in the dataset.
The sustainable Development Goal (SDGs) have successfully raised awareness and built momentum for taking collective action, while also remaining uncritical of the central causes of the environmental crises – economic growth, inequality, and overconsumption in the Global North. We analyse SDG 8 “Decent Work and Economic Growth” from the perspective of strong sustainability – as phenomena, institutions and ideologies – and find that it does not fit the criteria of strong sustainability. Based on this observation, we propose a novel framework for SDG8 in line with strong sustainability and the latest scientific research, “Sustainable Work and Economic Degrowth”, including a first proposal for new sub-goals, targets and indicators. This encompasses an integrated systems approach to achieving the SDGs’ overalls goals – a sustainable future for present and future generations. The key novel contributions of the paper include new indicators to measure societies’ dependence on economic growth, to ensure the provisioning of welfare independent of economic growth.
The “treadmill of production” economic system increasingly threatens to undermine the foundations of future human welfare. While urgent action is needed, conceptualisations of “the good life” (TGL) as the “imperial mode of living” (IML) of overconsumption are justifications upholding the system and driving forces behind the crises. German trade unions, which, as part of the historic bloc of the growth coalition, have tried to delay climate action in the name of jobs through “praising work”, have supported the hegemonic common sense of IML-TGL. This is an obstacle to environmental union organisation and progressive coalitions for social-ecological transformation. To investigate whether and to what extent divergent good sense counter-hegemonic narratives are present within German trade union discourses, we analyse the narratives of TGL and good work within the three biggest German unions – ver.di, IG Metall, and IG BCE – using Gramsci’s theory of common sense. We find that counter-narratives of TGL are present to different degrees within the unions and amongst interviewees. These can provide entry points for counter-hegemonic narratives of TGL and alliances with societal actors fighting for “solidary modes of living”, or a Good Life for All within planetary boundaries.
Background The European building and construction sector is extremely resource-intensive. This makes the renovation of existing buildings, including the adaptive reuse of cultural heritage buildings (ARCH), important for reducing the materials and energy intensity of the sector. Currently, Europe is embarking on a Circular Economy (CE) strategy that directly affects the environmental indicators for buildings and landscapes, including ARCH. However, there is a misalignment between macro-level European CE policy goals and micro-level renovation and management of existing buildings and ARCH. The analysis shows that macro European Union-level indicators are too narrowly defined to effectively guide the implementation of CE at the micro-project level for ARCH. Results This policy study develops a comprehensive ARCH Circular Environmental Impact Indicator Framework to close this gap by: (1) defining the research question; (2) identifying the causal network; and (3) selecting the best indicators. The study compares Circular Environmental Indicators for ARCH projects to current and developing European management schemes. Best practices in environmental impact assessment at the project level are highlighted for the building and construction sector in Europe. Conclusions The proposed new framework is a comprehensive and suitable list of explicitly circular environmental indicators for ARCH. The framework has immediate practical applications for practitioners and policymakers interested in the CE regime for buildings in Europe.
