“…For instance, a narrow functional unit definition for the mobility system mentioned above could be 1 personkilometer, whereas a wide functional unit for the same system could be a household's monthly transportation activities. This concept was later applied to account for behavioral change in a model of smart-homes combining agent-based modeling and a dynamic LCA (Walzberg et al, 2019). The results of the LCA were highly dependent on temporal and behavioral aspects, the latter accounting for a third of the variance in climate change impact.…”

“…Because the system's description is based on the description of its agents, a strength of the method is its ability to provide a detailed representation of the entities' decision process. As such, the method enables researchers to look for a behavioral model that more accurately represents the real-life decision process (Walzberg et al, 2019). When studying CE strategies, if economic agents always make rational decisions (maximizing their utility), traditional methods may be well-suited and would account for the technical, economic, and market potential of the CE strategies.…”

“…Indeed, the market potential may be constrained due to humans thinking with both a reflective system (leading to rational decisions) and an automatic system (leading to more instinctive decisions) (Thaler and Sunstein, 2008), which may divert from techno-economic optimum. Starting from the bottom-up, ABM often employs theories from social psychology such as the theory of planned behavior (Ajzen, 1991) to represent decisions involving both the reflective and automatic systems (Walzberg et al, 2019). Weaknesses of the ABM method are, however, the need for thorough validation and a significant amount of input data (Rand, 2019), the lack of consistency between how models are reported (Hinkelmann et al, 2011), and the difficulty to generalize some models (Hansen et al, 2019).…”

The goal of the circular economy (CE) is to transition from today's take-make-waste linear pattern of production and consumption to a circular system in which the societal value of products, materials, and resources is maximized over time. Yet circularity in and of itself does not ensure social, economic, and environmental performance (i.e., sustainability). Sustainability of CE strategies needs to be measured against their linear counterparts to identify and avoid strategies that increase circularity yet lead to unintended externalities. The state of the practice in quantitatively comparing sustainability impacts of circular to linear systems is one of experimentation with various extant methods developed in other fields and now applied here. While the proliferation of circularity metrics has received considerable attention, to-date, there is no critical review of the methods and combinations of methods that underlie those metrics and that specifically quantify sustainability impacts of circular strategies. Our critical review herein analyzes identified methods according to six criteria: temporal resolution, scope, data requirements, data granularity, capacity for measuring material efficiency potentials, and sustainability completeness. Results suggest that the industrial ecology and complex systems science fields could prove complementary when assessing the sustainability of the transition to a CE. Both fields include quantitative methods differing primarily with regard to their inclusion of temporal aspects and material efficiency potentials. Moreover, operations research methods such as multiple-criteria decision-making (MCDM) may alleviate the common contradictions which often exist between circularity metrics. This review concludes by suggesting guidelines for selecting quantitative methods most appropriate to a particular research question and making the argument that while there are a variety of existing methods, additional research is needed to combine existing methods and develop a more holistic approach for assessing sustainability impacts of CE strategies.

“…The heating demand is based on calculations of the hourly heat flux of each building. Walzberg et al (2019) [16] use an agentbased LCA approach to assess the potential of 100 Canadian smart homes. The authors identify human behavior and pro-environmental behavior change as large influencing factors in this context.…”

Growing environmental awareness in society increasingly influences individual everyday decisions, such as which product to buy or how to sustainably use it. Yet, available information to support these decisions is often limited, or difficult to understand particularly regarding sustainability. Effective ways of communicating environmental impacts of individual decisions are required to close this gap. While Life Cycle Assessment (LCA) is an established tool to evaluate environmental impacts of products and services and support environmental decision-making, the results are typically standardized and based on statistical or averaged data. However, for individuals, this information might be irrelevant, as it neglects personal situation, behavior, information need, or individual level of expertise. In tackling those central issues of personalization in LCA, this article focuses on two main questions: How can individual aspects be addressed in LCA and at which stages of the methodology can LCA be personalized? For this purpose, the ISO 14040/44 standards are analyzed regarding individuality, and current approaches in literature are presented. In an explorative approach, this research identifies two general approaches of personalizing LCA. A personalized Life Cycle Inventory (LCI) enables evaluating the environmental impacts of personal(ized) products and conditions. A broader personalization approach based on the flexibility of the methodological framework of LCA aims at providing understandable and relevant results for individual stakeholders. This article provides an overview, outlines key aspects of this vision, and points out further research needs to bring the concept into application.

“…Hampir semua penelitian dan rujukan yang membahas tentang perubahan perilaku menyimpulkan bahwa dibutuhkan waktu yang cukup lama untuk mengubah perilaku seseorang atau masyarakat (Centola, 2019)(Abbey-Lee & Dingemanse, 2019) (Jafaralilou, Zareban, Hajaghazadeh, Matin, & Didarloo, 2019) (Walzberg, Dandres, Merveille, Cheriet, & Samson, 2019). Hal ini ternyata tidak berlaku untuk perubahan perilaku dalam penggunaan jamban sehat di Desa Kaliasri.…”

Upaya pembangunan kesehatan merupakan tanggung jawab pemerintah, sektor swasta, maupun masyarakat. Teori dasar yang dikemukakan oleh Hendrik L. Blum (1974) menyebutkan bahwa status kesehatan seseorang ditentukan oleh genetik, sistem pelayanan kesehatan, perilaku, dan lingkungan. Pada konteks peran pemerintah hanya merupakan bagian kecil saja. Bagian terbesar justru ada pada sisi masyarakat, yaitu perilaku kesehatan dan lingkungan yang melingkupi kehidupan seseorang. Perubahan perilaku kesehatan merupakan tantangan yang cukup berat, yang membutuhkan perhatian secara intens, kontinyu dan membutuhkan waktu yang panjang. Perubahan perilaku dimulai dari keadaan tidak sadar menjadi sadar kemudian termotivasi untuk mencoba sesuatu yang baru, dilanjutkan dengan mengadopsi perilaku baru, mempertahankan, menghayati perilaku baru sehingga menjadi bagian dari perilaku dan kebiasaan sehari-hari.
