Consumption-based carbon assessments are essential for evaluating climate change responsibility. However, the results vary greatly depending on the boundary chosen, making them hard to understand for non-expert readers and hindering their uptake by policy makers. Sankey diagrams are a type of flow diagram where the thickness of a flow is proportion...

Background: Strategies to reduce the environmental impact of health care are often limited to greenhouse gas emissions. To broaden their scope, our aim was to determine the evolution of the resource footprints, dependency, and efficiency of health-care systems and to determine the relationship between this evolution and their Healthcare Access and...

The biophysical foundations of socioeconomic systems are underrepresented in the vast majority of macroeconomic models. This lack is particularly troublesome when considering the links between energy, matter and the economy in the context of the energy transition. As a remedy, we present here a biophysical stock-flow consistent macroeconomic model...

Background: Promoting active and public transportation is beneficial for both public health and the environment. However, evidence about the structural factors that can moderate interventions’ effectiveness is limited. The current study aims to quantify the moderating role of gasoline price on the effectiveness of interventions targeting healthier...

En établissant une causalité entre les activités des sociétés humaines et la transformation des phénomènes biophysiques globaux, la notion d’Anthropocène a imposé des approches systémiques et transdisciplinaires, seules à même de saisir l’ampleur des enjeux soulevés. Le dialogue proposé par cet article s’inscrit dans la lignée de ces travaux récent...

Consumption-based carbon assessments are essential for evaluating climate change responsibility. However, the results vary greatly depending on the scope chosen, making them confusing to non-expert readers and hindering their use for policymaking. This study aims to shed light on all the possible ways to calculate carbon footprints and on the impli...

Extracting, processing, and delivering energy requires energy itself, which reduces the net energy available to society and yields considerable socioeconomic implications. Yet, most mitigation pathways and transition models overlook net energy feedbacks, specifically related to the decline in the quality of fossil fuel deposits, as well as energy r...

By establishing a causal link between human activities and the transformation of global biophysical processes, the concept of the Anthropocene has positioned systemic and transdisciplinary approaches as the only ones capable of grasping the magnitude of challenges raised. The dialogue proposed in this article is in line with these recent works. It...

The low-carbon energy transition requires a widespread change in global energy infrastructures which in turn calls for important inputs of energy and materials. While the transport and electricity sectors have been thoroughly analyzed in this regard, that of the hydrocarbon industry has not received the same attention, maybe in part due to the diff...

To maintain perpetual economic growth, most energy transition scenarios bet on a break in the historical relationship between energy use and gross domestic product (GDP). Practical limits to energy efficiency are overlooked by such scenarios, in particular the fact that high-income individuals tend to buy goods and services that are more energy int...

Background The relationship between healthcare systems’ energy and resources expenditures and their quality is unclear to date. We need to know if healthcare systems could become more vulnerable to energy and resources crises or on the contrary more resilient over time. Our aim was to determine the evolution of the energy and resources expenditure...

Humanity is using mineral resources at an unprecedented level and demand will continue to grow over the next few decades before stabilizing by the end of the century, due to the economic development of populated countries and the energy and digital transitions. The demand for raw materials must be estimated with a bottom-up and regionalised approac...
