Data requirements for a successful circular economy
(2026) Müller, Felix; Bookhagen, Britta; Lehmann, Christian; Mählitz, Paul; Kahrl, Andreas; Schmitz, Martin; Kohlmeyer, Regina; Liesegang, Michael; Sperlich, Kristine; Kresse, Carolin; Nuss, Philip; Deutschland. Umweltbundesamt; Deutsche Rohstoffagentur
The circular economy is a transformation towards an economy that is resource-efficient, climate-neutral and resilient. Experts from the German Environment Agency and the German Raw Materials Agency systematically analyse available data on metal material cycles, focusing on secondary raw materials, recycling metrics, and material qualities. Case studies on aluminium and cobalt are used to identify existing data gaps and develop targeted recommendations for improving the database. Measures are proposed to increase the availability and quality of relevant data, in line with the goal of reducing bureaucracy.
Rethinking science-policy-practice interaction for transformative sustainability research and innovation in Europe
(2026) Lyytimäki, Jari; Kunttu, Leena; Bartke, Stephan; Eckert, Karl; Ellen, Gerald Jan; Gaugitsch, Helmut; Lipták, Boris; Maring, Linda; Mervaala, Erkki; Molina, Camilo; Neumann, Judith; Otto, Sonja; Rijken, Bart; Savage, Kester; Sluisveld, Mariësse A. E. van
Impactful knowledge generation and utilisation, aiming at addressing environmental and sustainability challenges, requires meaningful interaction between scientists, stakeholders, policymakers and society. This study identifies key success factors and challenges at the science-policy-practice interaction, drawing on document analysis, interviews, and workshops involving experts, policymakers, and funders of environmental and sustainability research and innovation across 14 European countries. Experiences from current practices highlight the highly variable contexts for interaction and communication throughout Europe, a diverse range of tools and approaches, and differing levels of available resources. Siloed structures and the need to engage various societal sectors and levels of governance remain significant challenges. The development and employment of expertise in communication, interaction and knowledge co-creation, capable to orchestrate this variability, is essential. Greater recognition of the diverse dimensions of inclusive participation is proposed to ensure that environmental and sustainability research and innovation, aimed at societal transformation, leaves no one behind. © 2026 Lyytimäki J et al.
Digitalisation and Resources (DigitalRessourcen)
(2025) Deutschland. Umweltbundesamt
Digitalisation is becoming increasingly pervasive in almost all areas of life. However, its impact on natural resources and climate change needs to be better understood. The UBA research project ‘Digitalisation and resources (DigitalRessourcen)’ investigates these interrelations with the aim of identifying strategic levers for sustainable development.
Climate mitigation contributions from circular economy actions
(2026) Günther, Jens; Fonteyn, Pieter; Nuss, Philip; Nielsen, Tobias; European Environment Agency. European Topic Centre on Circular economy and resource use
There is growing awareness of the key role that the circular economy can play in reducing greenhouse gas (GHG) emissions based been a notable increase in publications exploring the intersection of CE and climate mitigation and adaptation. This recent surge in research and political attention makes it a timely moment to take stock of existing findings and assess the climate mitigation potential of circular economy actions. Based on a review of over130 publications published between 2020 and March 2025 on this topic, this report provides a consolidated overview of the climate mitigation potential and identifying hot spots and potential “low hanging fruits”. A key finding is that estimates of mitigation potential vary widely across studies. Therefore, the report evaluates possible reasons for the differing results. The report concludes with key lessons learned based on the literature to support future policy developments and climate modelling efforts. © European Topic Centre on Circular economy and resource use
