Material circularity strategies in the stock-flow-service nexus of buildings, transport, electricity, machinery, furniture, and appliances
Increasing global population and rising levels of wealth are raising demands for services such as shelter and mobility, leading to greater resource use and environmental impacts. Circular strategies can reduce the resources required for these services. However, the potential of circular strategies to reduce material demand is rarely quantified. Here, we present a method to link service, product, and resource use with circular material reduction s…
Industrial Decarbonisation in a Fragmented World: Carbon Pricing with Border Adjustments Using Standardized Values
The European Carbon Border Adjustment Mechanism (CBAM) has the dual objective of preventing carbon leakage and promoting global carbon pricing. Yet pursuing both objectives at the same time might result in incomplete carbon leakage protection unless global carbon prices converge. As the current geopolitical situation makes such convergence seem unlikely in the near future, an extension of free allowance allocation is being discussed for affected …
Small increases in material stocks to achieve decent living standards globally
Global inequalities in resource use leave billions below decent living standards (DLS)—a proposal of universal minimum service levels required to meet essential human needs. Although research has examined the energy use and greenhouse gas emission implications of achieving universal DLS, little is known about the necessary expansion of societies’ material stocks in buildings, infrastructure and machinery. Here we estimate that closing global DLS …
Water, land, materials, and emissions for providing decent living standards around the world
Where is my footprint located? Estimating the geographical variance of hybrid LCA footprints
Current implementations of hybrid life cycle assessment (LCA) mostly do not fully exploit valuable information from multi‐regional input–output databases by aggregating regional supply chains to the lower geographical resolution of process LCA databases. We propose a method for sampling the various individual regions within the aggregated regional scope of LCA processes. This sampling maximizes the information content of hybrid LCA footprint resu…
From extraction to end‐uses and waste management: Modeling economy‐wide material cycles and stock dynamics around the world
Material stocks of infrastructure, buildings, and machinery are the biophysical basis of production and consumption. They are a crucial lever for resource efficiency and a sustainable circular economy. While material stock research has proliferated over the last years, most studies investigated specific materials or end‐uses, usually not embedded into an economy‐wide perspective. Herein, we present a novel version of the economy‐wide, dynamic, in…
Scenario analysis of supply‐ and demand‐side solutions for circular economy and climate change mitigation in the global building sector
Residential and non‐residential buildings are a major contributor to human well‐being. At the same time, buildings cause 30% of final energy use, 18% of greenhouse gas emissions (GHGE), and about 65% of material accumulation globally. With electrification and higher energy efficiency of buildings, material‐related emissions gain relevance. The circular economy (CE) strategies, narrow, slow, and close , together with wooden buildings, can reduce m…
Decent living standards, prosperity, and excessive consumption in the Lorenz curve
Sustainable production and consumption allows every individual to meet their basic needs and societies to flourish, all with limited overall throughput constrained by ecological ceilings. The question is how exactly basic needs satisfaction, flourishing societies, and limited throughput can come together. Based on the insight that decent living standards constrain the slope of the Lorenz curve for the lowest decile, a simple model can be derived …
A review of methods to trace material flows into final products in dynamic material flow analysis: From industry shipments in physical units to monetary input–output tables, Part 1
Dynamic material flow analysis (dMFA) is widely used to model stock‐flow dynamics. To appropriately represent material lifetimes, recycling potentials, and service provision, dMFA requires data about the allocation of economy‐wide material consumption to different end‐use products or sectors, that is, the different product stocks, in which material consumption accumulates. Previous estimates of this allocation only cover few years, countries, and…
Lessons, narratives, and research directions for a sustainable circular economy
The current enthusiasm for the circular economy (CE) offers a unique opportunity to advance the impact of research on sustainability transitions. Diverse interpretations of CE by scholars, however, produce partly opposing assessments of its potential benefits, which can hinder progress. Here, we synthesize policy‐relevant lessons and research directions for a sustainable CE and identify three narratives—optimist, reformist, and skeptical—that und…
Exploring the global trade networks of the tungsten supply chain: Insights into the physical and monetary mismatch among countries
International trade is essential to bridge the imbalance between supply and demand of materials along with different nations effectively, especially for critical raw materials such as tungsten that are highly geographically unequally distributed. However, the international trade flows and their complex networks that link those participating nations have remained largely unexplored, which leads to inexplicable concerns for materials' criticality a…
Sector‐specific scenarios for future stocks and flows of aluminum: An analysis based on shared socioeconomic pathways
Linking service provision to material cycles: A new framework for studying the resource efficiency–climate change (Recc) nexus
Material production accounts for 23% of all greenhouse gas emissions. More efficient use of materials—through decoupling of services that support human well‐being from material use—is imperative as other emission mitigation options are expensive. An interdisciplinary scientific assessment of material efficiency and its links to service provision, material cycle management, and climate policy is needed to identify effective strategies and help des…
Quantifying longevity and circularity of copper for different resource efficiency policies at the material and product levels
Resource efficiency strategies are emerging on policy agendas worldwide. Commonly, resource efficiency policies aim at decreasing losses at the waste management stage and, thus, diverge from public interest in more comprehensive resource efficiency measures that include a focus the earlier material life cycle stages. Just in recent years, improvements in the lifetimes of products and increased repair and reuse ability have become policy objective…
Material efficiency and climate change mitigation of passenger vehicles
A transition to electric vehicles and renewable energy is currently underway but may not be rapid enough in order to reach ambitious climate change mitigation targets. Therefore, additional, preferably instantaneous, measures are needed for quick emission reductions, which is where material efficiency (ME) could constitute a promising solution. ME strategies include but are not limited to vehicle lightweighting through material substitution, incr…
A comprehensive set of global scenarios of housing, mobility, and material efficiency for material cycles and energy systems modeling
Scenario-based assessments are a useful tool to explore unknown futures and inform decision makers and the public of the consequences of different courses of action. Scenario developments in industrial ecology have focused on disparate components of the socioeconomic metabolism and case studies, and few efforts of comprehensive and cumulative scenario formulation are documented. Many important, empirically derived relationships between material c…
Implications of the distribution of German household environmental footprints across income groups for integrating environmental and social policy design
The distribution of German household environmental footprints (EnvFs) across income groups is analyzed by using EXIOBASE v3.6 and the consumer expenditure survey of 2013. Expenditure underreporting is corrected by using a novel method, where the expenditures are modeled as truncated normal distribution. The focus lies on carbon (CF) and material (MF) footprints, which for average German households are 9.1 0.4 metric tons CO 2 e and 10.9 0.6 metri…
Material efficiency and its contribution to climate change mitigation in Germany: A deep decarbonization scenario analysis until 2060
Germany's greenhouse gas emissions have declined by 35% since 1990, and the national policy ambition is to become largely carbon-neutral by 2050. A change of the industrial landscape and a partial transformation of energy supply have contributed to reductions so far, but for deep reductions, a deep transformation of the country's industrial metabolism is needed. While energy efficiency is well established, the same cannot be said for material eff…

The methods and algorithms of MFA have improved over the last few years, but a flexible platform that integrates recent modeling advances such as simultaneous consideration of the product, component, material and chemical element levels, lifetime models, and uncertainty treatment is not available. There is also no versatile data format for exchanging dat…
Interactive Visualization and Industrial Ecology: Applications, Challenges, and Opportunities
The emergence of increasingly complex data in industrial ecology (IE) has caused scholarly interest in interactive visualization (IV). IV allows users to interact with data, aiding in processing and interpreting complex datasets, processes, and simulations. Consequently, IV can help IE practitioners communicate the complexities of their methods and results, shed light on the underlying research assumptions, and enable more transparent monitoring …
A general data model for socioeconomic metabolism and its implementation in an industrial ecology data commons prototype
Until this day, data in industrial ecology (IE) have been commonly seen as existing within the domain of particular methods or models, such as input–output, life cycle assessment, urban metabolism, or material flow analysis data. This artificial division of data into methods contradicts the common phenomena described by those data: the objects and processes in the industrial system, or socioeconomic metabolism (SEM). A consequence of this scatter…
Material efficiency strategies to reducing greenhouse gas emissions associated with buildings, vehicles, and electronics—a review
As one quarter of global energy use serves the production of materials, the more efficient use of these materials presents a significant opportunity for the mitigation of greenhouse gas (GHG) emissions. With the renewed interest of policy makers in the circular economy, material efficiency (ME) strategies such as light-weighting and downsizing of and lifetime extension for products, reuse and recycling of materials, and appropriate material choic…

Carbon Emissions of Infrastructure Development
Identifying strategies for reconciling human development and climate change mitigation requires an adequate understanding of how infrastructures contribute to well-being and greenhouse gas emissions. While direct emissions from infrastructure use are well-known, information about indirect emissions from their construction is highly fragmented. Here, we estimated the carbon footprint of the existing global infrastructure stock in 2008, assuming cu…
Transforming the Norwegian Dwelling Stock to Reach the 2 Degrees Celsius Climate Target: Combining Material Flow Analysis and Life Cycle Assessment Techniques
Residential buildings account for about one‐third of the final energy demand in Norway. Many cost‐effective measures for reducing heat losses in buildings are known, and their implementation may make the building sector one of the largest contributors to climate change mitigation. To determine the sectoral emission reduction potential, we model a complete transformation of the dwelling stock by 2050 by applying both renovation and reconstruction …
The role of in-use stocks in the social metabolism and in climate change mitigation
Dynamic Models of Fixed Capital Stocks and Their Application in Industrial Ecology
Industrial assets or fixed capital stocks are at the core of the transition to a low‐carbon economy. They represent substantial accumulations of capital, bulk materials, and critical metals. Their lifetime determines the potential for material recycling and how fast they can be replaced by new, more efficient facilities. Their efficiency determines the coupling between useful output and energy and material throughput. A sound understanding of the…
Lifting Industrial Ecology Modeling to a New Level of Quality and Transparency: A Call for More Transparent Publications and a Collaborative Open Source Software Framework
Industrial ecology (IE) is a maturing scientific discipline. The field is becoming more data and computation intensive, which requires IE researchers to develop scientific software to tackle novel research questions. We review the current state of software programming and use in our field and find challenges regarding transparency, reproducibility, reusability, and ease of collaboration. Our response to that problem is fourfold: First, we propose…
A General System Structure and Accounting Framework for Socioeconomic Metabolism
A wide spectrum of accounting frameworks and models is available to describe socioeconomic metabolism (SEM). Despite the common system of study, a large variety of terms and representations of that system are used by different models. This makes it difficult for practitioners to compare and choose a model or model combination that is fit for purpose. To facilitate model comparison, we analyze the system structure of material flow analysis (MFA); …
Socioeconomic metabolism as paradigm for studying the biophysical basis of human societies
Toward a Practical Ontology for Socioeconomic Metabolism
The complexity of data and methods in industrial ecology (IE) keeps growing, and the demand for comprehensive and interdisciplinary assessments increases. To keep up with this development, the field needs a data infrastructure that allows researchers to annotate, store, retrieve, combine, and exchange data at low cost, without loss of information, and across disciplines and model frameworks. A consensus‐building debate about how to describe the c…
An Australian Multi‐Regional Waste Supply‐Use Framework
The production of waste creates both direct and indirect environmental impacts. A range of strategies are available to reduce the generation of waste by industry and households, and to select waste treatment approaches that minimize environmental harm. However, evaluating these strategies requires reliable and detailed data on waste production and treatment. Unfortunately, published Australian waste data are typically highly aggregated, published…
Balance issues in input–output analysis: A comment on physical inhomogeneity, aggregation bias, and coproduction
Solid Waste and the Circular Economy: A Global Analysis of Waste Treatment and Waste Footprints
Detailed and comprehensive accounts of waste generation and treatment form the quantitative basis of designing and assessing policy instruments for a circular economy (CE). We present a harmonized multiregional solid waste account, covering 48 world regions, 11 types of solid waste, and 12 waste treatment processes for the year 2007. The account is part of the physical layer of EXIOBASE v2, a multiregional supply and use table. EXIOBASE v2 was us…
Critical appraisal of the circular economy standard BS 8001: 2017 And a Dashboard of Quantitative System Indicators for Its Implementation in Organizations
So far, organizations had no authoritative guidance on circular economy (CE) principles, strategies, implementation, and monitoring. Consequentially, the British Standards Institution recently launched a new standard “BS 8001:2017 – Framework for implementing the principles of the circular economy in organizations”. BS 8001:2017 tries to reconcile the far-reaching ambitions of the CE with established business routines. The standard contains a com…
Choice of Allocations and Constructs for Attributional or Consequential Life Cycle Assessment and Input‐Output Analysis
The divide between attributional and consequential research perspectives partly overlaps with the long‐standing methodological discussions in the life cycle assessment (LCA) and input‐output analysis (IO) research communities on the choice of techniques and models for dealing with situations of coproduction. The recent harmonization of LCA allocations and IO constructs revealed a more diverse set of coproduction models than had previously been un…
Nullius in Verba1: Advancing Data Transparency in Industrial Ecology
With the growth of the field of industrial ecology (IE), research and results have increased significantly leading to a desire for better utilization of the accumulated data in more sophisticated analyses. This implies the need for greater transparency, accessibility, and reusability of IE data, paralleling the considerable momentum throughout the sciences. The Data Transparency Task Force (DTTF) was convened by the governing council of the Inter…
