Australia's circular economy metrics and indicators
This article presents a comprehensive economy‐wide material flow analysis of the Australian economy in 2019, examining the domestic extraction, trade, end‐of‐life flows, and recycling for all materials. The results highlight Australia's role as a natural resource supplier, with metals and fossil fuels being primary contributors. Through material flow analysis, we found that in 2019 Australia extracted 2587 Mt of natural resources, exported a subs…
Impacts of global trade on cropland soil-phosphorus depletion and food security
Targeting 1.5 degrees with the global carbon footprint of the Australian Capital Territory
In 2019 the Australian Capital Territory (ACT) government stated an ambition to prioritise reduction of Scope 3 greenhouse gas emissions, the size of which had not been fully quantified previously. This study calculated the total carbon footprint of the ACT in 2018, including Scope 1, 2 and 3 emissions and modelled scenarios to reduce all emissions in line with a 1.5 °C target approach. This is the first time a multi-scale analysis of local, sub-…
Modelling ambitious climate mitigation pathways for Australia's built environment
Creating multi‐scale nested MRIO tables for linking localized impacts to global consumption drivers
Industrial Ecology Virtual Laboratories (IELabs) enable the construction of national‐to‐local‐scale multi‐regional input–output (MRIO) models. These IELabs have been proven to be especially important for analyzing research questions that warrant sub‐national spatial detail. The field of industrial ecology has clearly progressed from the time of national‐only input–output tables. Here, we present a newly developed tool called NLab—“nested IELab”—t…
Opportunities and barriers to net-zero cities
A review of trends and drivers of greenhouse gas emissions by sector from 1990 to 2018
Global greenhouse gas (GHG) emissions can be traced to five economic sectors: energy, industry, buildings, transport and AFOLU (agriculture, forestry and other land uses). In this topical review, we synthesise the literature to explain recent trends in global and regional emissions in each of these sectors. To contextualise our review, we present estimates of GHG emissions trends by sector from 1990 to 2018, describing the major sources of emissi…
A multi-regional input-output analysis of direct and virtual urban water flows to reduce city water footprints in Australia
Modern slavery footprints in global supply chains
Slavery is more prevalent today than at any point in human history. Society's heightened scrutiny and new government policy is forcing businesses and nations to act in lieu of reputational, financial, and legal repercussions. However, slavery hides within complex supply chains, making it difficult to identify instances of human exploitation. This study takes a consumption perspective by investigating the potential of footprinting in exposing mode…
Three‐scope carbon emission inventories of global cities
A major challenge for cities taking action on climate change is assessing and managing the contribution of urban consumption which triggers greenhouse gas (GHG) emissions outside city boundaries. Using a novel method of creating city‐level input–output tables, we present the first consistent, large‐scale, and global assessment of three‐scope GHG inventories for 79 members of the C40 Cities Climate Leadership Group. These inventories cover the emi…
Transdisciplinary resource monitoring is essential to prioritize circular economy strategies in cities
Seeking to meet sustainability targets, cities are promoting a number of circular economy initiatives. Whether or not these actions help cities to approach sustainable resource management is often unclear. To identify, prioritize and monitor resource-efficient strategies, cities can look for targets and indicators among the Sustainable Development Goals (SDGs). While the SDGs provide useful goals, they lack applicable and accurate indicators for …
Priorities for science to support national implementation of the sustainable development goals
The sustainable development goals (SDGs) provide a framework of goals, targets, and indicators designed to guide national implementation of sustainable development to 2030. Several aspects of the framework are challenging, including its complex and integrated scope and transformational character. A range of approaches developed in the sustainability sciences can assist countries to address these challenges. In this paper, we evaluate recent scien…

Scientists’ warning on affluence
For over half a century, worldwide growth in affluence has continuously increased resource use and pollutant emissions far more rapidly than these have been reduced through better technology. The affluent citizens of the world are responsible for most environmental impacts and are central to any future prospect of retreating to safer environmental conditions. We summarise the evidence and present possible solution approaches. Any transition towar…
The sharing economy and sustainability – assessing Airbnb’s direct, indirect and induced carbon footprint in Sydney
A peer-to-peer sharing approach for the accommodation sector such as Airbnb has been suggested as a more environmentally sustainable alternative to conventional forms of accommodation services. This study evaluates the carbon footprint of Airbnb hosts in Sydney. The Airbnb platform and its hosts together generate direct and indirect carbon footprints in the range of 7.27 to 9.39 kg CO2e per room and night. The extra income of Airbnb hosts leads t…
Quantifying carbon flows in Switzerland
Modelling frameworks that aim to support policymakers in deriving effective measures to reduce environmental impacts should provide both: quantitative information on locally occurring consumption patterns and production systems as well as assessment of policy scenario outcomes. Regionalised models that can deliver on these aims are emerging, but are currently limited in resolution or have other restrictions. An advanced model can be achieved by e…
A two-stage clustering approach to investigate lifestyle carbon footprints in two Australian cities
Given the key role of households in driving global emissions and resource use, a change in their consumption behaviours towards more sustainable levels is essential to reduce worldwide adverse environmental impacts. Thereby, focusing on cities is especially important because of today’s large share of the global population living in cities and because local authorities are close to the needs of their residents. However, devising targeted and effec…
Implications of Trends in Energy Return on Energy Invested (Eroi) for Transitioning to Renewable Electricity
Advancements in Input‐Output Models and Indicators for Consumption‐Based Accounting
The use of global, multiregional input‐output (MRIO) analysis for consumption‐based (footprint) accounting has expanded significantly over the last decade. Most of the global studies on environmental and social impacts associated with consumption or embodied in international trade would have been impossible without the rapid development of extended MRIO databases. We present an overview of the developments in the field of MRIO analysis, in partic…
What can we learn from consumption-based carbon footprints at different spatial scales? Review of policy implications
Background : Current climate change mitigation policies, including the Paris Agreement, are based on territorial greenhouse gas (GHG) accounting. This neglects the understanding of GHG emissions embodied in trade. As a solution, consumption-based accounting (CBA) that reveals the lifecycle emissions, including transboundary flows, is gaining support as a complementary information tool. CBA is particularly relevant in cities that tend to outsource…

An Iterative Framework for National Scenario Modelling for the Sustainable Development Goals (SDGs)
The recently adopted global Sustainable Development Goals (SDGs) are intended to catalyse implementation of sustainable development. Their success or failure will rely heavily upon national implementation. However, the SDGs represent a broad, integrated and complex agenda that will be very challenging for countries to implement. Over the past decade, scenario analysis has emerged as a method that is particularly well suited to sustainable develop…

The Environmental Impacts of Consumption at a Subnational Level
This article analyzes the environmental effects of resource consumption at a subnational level (by Cardiff, the capital city of Wales), using the Ecological Footprint as a measure of impact assessment. The article begins by providing a short critique of the Footprint methodology and the limitations of methods traditionally used to calculate national Footprint accounts. We then describe the Footprint methodology developed by the Stockholm Environm…

Companies on the Scale
A determination of the sustainability performance of a company ought to fulfill certain requirements. It has to take into account the direct impacts from on‐site processes as well as indirect impacts embodied in the supply chains of a company. This life cycle thinking is the common theme of popular footprint analyses, such as carbon, ecological, or water footprinting. All these indicators can be incorporated into one common and consistent account…

Uncertainty Analysis for Multi-Region Input–output Models – A Case Study of the Uk's Carbon Footprint
This paper reviews and demonstrates methods available for estimating standard deviations for carbon multipliers in a multi-regional input–output (MRIO) framework. We attempt to capture all possible variations of underlying data and calculation procedures in a global MRIO model constructed with particular focus on the UK. We consider these variations to be random, and determine the stochastic variation of the whole MRIO system using Monte Carlo te…
A Carbon Footprint Time Series of the Uk – Results From a Multi-Region Input–output Model
The framework and results of an international multi-region input–output (MRIO) model for the UK are presented. A time series of balanced input–output tables for the UK was constructed for the period 1992 to 2004 by using a matrix balancing procedure that is able to handle conflicting external data and inconsistent constraints. Detailed sectoral and country-specific trade data for the UK were compiled and reconciled with the UK input–output data, …

Defining (Urban) Producer and Consumer Sinks
This contribution was prompted by the article “Gross Direct and Embodied Carbon Sinks for Urban Inventories” by Mohareb and Kennedy published in this issue. The authors define two types of urban carbon sinks—direct and embodied—and discuss their relation to producer and consumer emissions (and sinks) accounting. This commentary continues that discussion by clarifying boundary considerations and definitions between producer and consumer sinks, and…
General approaches for assessing urban environmental sustainability
Consumption-based GHG emission accounting
Global GHG emissions continue to rise, with nearly a quarter of it due to trade that is not currently captured within global climate policy. In the context of current trade patterns and limited global cooperation on climate change, the feasibility of consumption-based emissions accounting to contribute to a more comprehensive (national) policy framework in the UK is investigated. Consumption-based emissions results for the UK from a range of mode…
Carbon footprints of cities and other human settlements in the UK
A growing body of literature discusses the CO2 emissions of cities. Still, little is known about emission patterns across density gradients from remote rural places to highly urbanized areas, the drivers behind those emission patterns and the global emissions triggered by consumption in human settlements - referred to here as the carbon footprint. In this letter we use a hybrid method for estimating the carbon footprints of cities and other human…
Humanity’s unsustainable environmental footprint
Within the context of Earth’s limited natural resources and assimilation capacity, the current environmental footprint of humankind is not sustainable. Assessing land, water, energy, material, and other footprints along supply chains is paramount in understanding the sustainability, efficiency, and equity of resource use from the perspective of producers, consumers, and government. We review current footprints and relate those to maximum sustaina…
The material footprint of nations
Metrics on resource productivity currently used by governments suggest that some developed countries have increased the use of natural resources at a slower rate than economic growth (relative decoupling) or have even managed to use fewer resources over time (absolute decoupling). Using the material footprint (MF), a consumption-based indicator of resource use, we find the contrary: Achievements in decoupling in advanced economies are smaller tha…

The Concept of City Carbon Maps
Cities are thought to be associated with most of humanity's consumption of natural resources and impacts on the environment. Cities not only constitute major centers of economic activity, knowledge, innovation, and governance—they are also said to be linked to approximately 70% to 80% of global carbon dioxide emissions. This makes cities primary agents of change in a resource‐ and carbon‐constraint world. In order to set meaningful targets, desig…
