“…As life cycle assessment can quantify not only the manufacturing process consumption and emissions but also those of upstream processes and end-of-life, life cycle assessment will provide a powerful tool to support better green construction management from a broader perspective, such as the material production stage for construction activities (Braulio-Gonzalo et al 2022;Desai and Bheemrao 2022;Dong et al 2018;Monteiro and Soares 2022;Shafique et al 2020;Wang et al 2020b).

The construction industry is a major user of non-renewable energy and contributor to emission of greenhouse gases, thus requiring to achieve net-zero carbon emissions by 2050. Indeed, construction activities account for 36% of global energy consumption and 39% of global carbon dioxide emissions. Reducing carbon emissions requires adapted government policies, carbon emission analysis and calculation models, and sustainable materials. Here, we review green construction with focus on history, carbon emissions, policies, models, life cycle assessment, and sustainable materials such as biochar, bioplastic, agricultural waste, animal wool, fly ash and self-healing concrete. Analysis of carbon emissions over the building life cycle shows that the construction phase accounts for 20–50% of total carbon emissions. The average ratio of construction phase annual emissions to operation phase emissions is 0.62. We present national policy frameworks and technology roadmaps from the United States of America, Japan, China, and the European Union, highlighting plans to achieve carbon neutrality in the building sector.

“…Considering the applied LCA methodology reference (see Figure 9a) it was found that most papers were referencing the ISO standards for LCA (ISO 14040/44), either as a sole methodologi- Looking at Figure 8c, it is seen that most studies (n = 53) assess CE solutions up front, using, e.g., recycled waste in new materials or structures [39], recycled concrete in aggregates [40], or reusing cut-offs from the automotive industry, or offal, in new building façade designs [41]. Some (n = 17) assessed prospective CE actions, e.g., through adaptable design and DfD [42][43][44][45][46][47][48], and the rest (n = 15) assessed both up front and prospectively, e.g., through cases that both used secondary materials and were designed for recycling or reuse [33,37,[49][50][51].…”

Life Cycle Assessments of Circular Economy in the Built Environment—A Scoping Review

2022

View full text Add to dashboard Cite

The Circular Economy (CE) is gaining traction throughout all industries and nations globally. However, despite several attempts, no one-off solutions for assessing the benefits and pitfalls of CE have been established, and neither have any measures with which to determine decisions. In line with this general observation, the Built Environment (BE) is no different. A tendency is observed in which, for the assessment of the environmental impacts of CE, a Life Cycle Assessment (LCA) has been deemed suitable. This paper presents a scoping review, using the PRISMA statement extension for scoping reviews, documenting how LCA has been applied for assessment of CE in the BE. The review covers a broad scope of literature, scoping the landscape, and delimits it into publications where CE strategy has been defined explicitly and described as a CE investigation. Among the LCAs applied, the dominant system boundary choice is the attributional approach. The authors open the discussion on whether this is actually suitable for answering the questions posed in the CE paradigm. From the review, and the discussion, the conclusion suggests that there is no dominant procedure in applying LCA of CE in the BE, even despite commonly developed LCA standards for the BE. Few studies also present the consideration to reconsider the applied LCA, as CE puts new questions (and thereby a potentially greater system boundary, as CE may imply greater societal consequences) that do not necessarily fit into the linear LCA framework currently applied in the BE.
