Successful Workshop of IAM-Circ, Circomod, CircEUlar, and ScarCyclET on Circular Economy Economic Modelling

The EU & ANR projects IAM-Circ, Circomod, CircEUlar, and ScarCyclET,  in collaboration with the European Association of Young Economists (EAYE), hosted a workshop on Circular Economy Economic Modelling on July 1, 2024 . This event, held at premises of the Leuven University served as a precursor to the Annual Conference of the European Association of Environmental and Resource Economists (EAERE). The workshop brought together over 45 participants from academia and policy advisory stakeholders.  

This workshop successfully provided an engaging and enriching environment for emerging economists to contribute to and expand their understanding of the economic dimensions underpinning circular economies, laying a robust foundation for future research and policy development in this critical area.

The workshop featured a series of insightful presentations addressing various facets of circular economy modeling and policies. Xi Sun focused on the complexities and incentives in modeling policies aimed at closing the material loop. Miao Dai from the University of Montpellier discussed strategies for efficient recycling. Claudia Ranocchia from the Autonomous University of Madrid explored the dynamics of peer-to-peer sharing and price competition. Adil Boufarsi from the University Grenoble Alpes presented on the impacts of credit constraints within the circular economy.

Other notable presentations included Malin Wiese from Leipzig University on integrating natural capital dynamics in climate change assessments; Eugenie Joltreau (RFF CMCC) discussing the transition from micro to macro circularity in climate mitigation; Lucas Straub from the University of Utrecht on incorporating material and circular economy dynamics into cost-benefit integrated assessment modeling for climate mitigation; and Stefani Rivic from TU Wien, who highlighted the limitations and challenges of recycling and utilization targets within circular plastics management using a general economic equilibrium model. Additionally, Darius Corbier (RFF-CMCC) discussed the impact of Extended Producer Responsibility schemes on consumer habits and sustainable consumption practices, while Xinyu Li from PBL examined the effects of EU Green Deal policies on global resources management and climate change by integrating material intensity into Computable General Equilibrium (CGE) models.

The keynote address by Aude Pommeret of the University Savoie Mont Blanc was a highlight, discussing the intricate relationship between sustainable infrastructure for renewables, the complexities of the energy transition, critical raw materials, and the circular economy.

The policy session featured notable contributions from Gillian Foster of the Joint Research Centre (JRC), European Commission, who elaborated on various models and toolboxes developed by the JRC, with a specific focus on textile recycling and the pertinent research questions being tackled. Toon Vandyck from the Organization for Economic Cooperation and Development (OECD) presented on resource use modeling, the environmental impacts of material extraction and processing, and the effectiveness of policies aimed at decoupling economic growth from material use. His discussion also covered extensive research on plastics, which garnered significant interest from the participants.


The workshop offered researchers invaluable feedback from senior colleagues and highlighted the latest advancements in circular economy studies.

Formal sessions were enriched by productive and informal exchanges during coffee and lunch breaks. The day concluded with a relaxed dinner, where participants enjoyed local, plant-based cuisine and engaged in friendly conversations on both research and non-research topics.)
