What can life cycle assessment modeling gain from agent-based modeling
Integration of agent-based modeling (ABM) and life cycle assessment (LCA) has been proposed and applied as an approach to leverage the complementary strengths of both methods in assessing sustainability impacts within complex socio-technical systems. However, the existing literature has focused primarily on the technical “how” of integration, while the rationale, benefits and drawbacks have received less attention. In this forum paper, we revisit…
Regional sensitivity analysis to assess critical parameters in circular economy interventions
In evaluating a circular economy (CE), one needs to address the complexity arising from indicators with multiple objectives, multiple means of implementation with combinations of CE strategies, and the uncertainty inherent in resource cycle systems. Regional sensitivity analysis (RSA) is a version of global sensitivity analysis that can be used to determine whether the output variables of a mathematical model lie within a certain range. Although …
Prospective life cycle and circularity assessment of circular business models using an empirically grounded agent‐based model
Despite the need for methodologies that support early‐phase decision‐making in the transition to a circular economy, current sustainability assessments often lack a prospective method that dynamically accounts for consumer decision‐making based on empirical evidence. This study addresses this need by evaluating the circularity and environmental impacts of circular business models over a 30‐year period, using an empirically grounded agent‐based mo…
Who is self-committed to climate action? Exploring decarbonisation actions and target gaps using carbon footprint calculator data in Japan
Lifestyle change modelling for climate change mitigation
Lifestyle changes are an essential, complementary measure for reducing greenhouse gas emissions and, therefore, also an important ingredient to climate policy. Computational models of lifestyle changes and their contribution to climate change mitigation can provide valuable insights in support of decision-making by individuals and policymaking. In this Perspective, we examine four modelling approaches with this in mind: input-output analysis, lif…
All options, not silver bullets, needed to limit global warming to 1.5 °C
Climate science provides strong evidence of the necessity of limiting global warming to 1.5 °C, in line with the Paris Climate Agreement. The IPCC 1.5 °C special report (SR1.5) presents 414 emissions scenarios modelled for the report, of which around 50 are classified as ‘1.5 °C scenarios’, with no or low temperature overshoot. These emission scenarios differ in their reliance on individual mitigation levers, including reduction of global energy …
Exploring carbon footprint reduction pathways through urban lifestyle changes
Cities and urban consumers play a central role in the transition to a decarbonized society. Building on existing studies that identify the significant contributions of lifestyle changes, this study proposes a practical methodology for modeling and exploring city-specific carbon footprint reduction pathways through lifestyle changes to decarbonization. It uses an input–output approach with mixed-unit consumption data and the concept of adoption ra…
Lifestyle carbon footprints and changes in lifestyles to limit global warming to 1.5 °C, and ways forward for related research
This paper presents an approach for assessing lifestyle carbon footprints and lifestyle change options aimed at achieving the 1.5 °C climate goal and facilitating the transition to decarbonized lifestyles through stakeholder participatory research. Using data on Finland and Japan it shows potential impacts of reducing carbon footprints through changes in lifestyles for around 30 options covering food, housing, and mobility domains, in comparison …

Ship Breaking and the Steel Industry in Bangladesh
Bangladesh has emerged as a leading ship breaking nation. We conducted a material flow analysis of steel in Bangladesh with an emphasis on the ship breaking industry (SBI). The total aggregate domestic steel consumption in fiscal year (FY) 2010 was 2,930,000 tonnes (t) in Bangladesh; SBI met approximately 51% of the demand for raw materials and 37% of the demand for finished steel products. Rolling industries output in FY2010 was 1,451,000 t; 23%…
