The concept of a circular economy has instilled substantial hopes that it will help forging patterns of resource use compatible with Planetary Boundaries. Many countries are implementing circularity policies to reduce wastes and emissions, while also fostering economic growth. Research and...

Strategies for absolute reductions of resource use are required to address the multiple environmental crisis. We herein investigate, what the material footprint indicator (MF), used to monitor progress towards UN Sustainable Development Goals 8 and 12, shows but also hides about material flows...

Chapter 1 of this report reviews a number of approaches to conceptualize and operationalize biophysical constraints for economic performance. The starting point is a scoping study by Cambridge Econometrics and Sustainable Europe Research Institute (SERI) that reviews a large number of...

Most economic models struggle to incorporate biophysical relationships between materials, energy and emissions, in order to appropriately deal with biophysical constraints of supply (and possibly also demand). After the incorporation of biophysical constraints, some functions produced surprising...

With reference to the use of material and energy resources, we seek to • underline the need for a marked socio-ecological transition. Business-as-usual will fail in the face of an unprecendented rise in global demand, a rising price level and volatility of raw materials and indications of...
