Veröffentlichung Der Weg zu einer global gerechten zirkulären Wirtschaft(2023) Janz, Alexander; Kosmol, Jan; Messner, DirkVeröffentlichung Internationale Umwelt- und Nachhaltigkeitspolitik während und nach der Covid-19 Pandemie(2020) Ginzky, Harald; Kosmol, Jan; Schwirn, KathrinVeröffentlichung Monitoring framework for the use of natural resources in Germany(2021) Nuss, Philip; Frerk, Michel; Günther, Jens; Golde, Michael; Kosmol, Jan; Müller, FelixIndicators are required to monitor the progress of resource and circular economy policies. The German Sustainable Development Strategy and Resource Efficiency Program already include a number of indicators for mapping Germany's resource use and socio-economic metabolism. However, currently used indicators only include a subset of natural resources and often lack an impact evaluation (e.g., considering resource scarcity or environmental relevance). Resource and environmental footprints indirectly caused through the trade of goods have so far only partly been considered by German resource policy and in official statistics. As a result, burden shifting between different resource categories, world regions, or environmental effects can remain undetected. To fill this gap, we discuss the overall scope of natural resource monitoring in Germany and review existing resource indicators evaluating them against a set of predefined criteria. We then propose a possible monitoring framework for Germany consisting of a materials-layer (the focus of resource and circular economy policies to date) for the evaluation of material flows and stocks, and corresponding water, land, and emissions-layers which should be monitored simultaneously to track contributions to the overarching objectives of resource and circular economy policies. Possible indicators and data sources are discussed and an outlook for future research provided. © 2021 The AuthorsVeröffentlichung A review of methods and data to determine raw material criticality(2020) Schrijvers, Dieuwertje; Hool, Alessandra; Blengini, Gian Andrea; Kosmol, Jan; Nuss, PhilipThe assessment of the criticality of raw materials allows the identification of the likelihood of a supply disruption of a material and the vulnerability of a system (e.g. a national economy, technology, or company) to this disruption. Inconclusive outcomes of various studies suggest that criticality assessments would benefit from the identification of best practices. To prepare the field for such guidance, this paper aims to clarify the mechanisms that affect methodological choices which influence the results of a study. This is achieved via literature review and round table discussions among international experts. The paper demonstrates that criticality studies are divergent in the system under study, the anticipated risk, the purpose of the study, and material selection. These differences in goal and scope naturally result in different choices regarding indicator selection, the required level of aggregation as well as the subsequent choice of aggregation method, and the need for a threshold value. However, this link is often weak, which suggests a lack of understanding of cause-and-effect mechanisms of indicators and outcomes. Data availability is a key factor that limits the evaluation of criticality. Furthermore, data quality, including both data uncertainty and data representativeness, is rarely addressed in the interpretation and communication of results. Clear guidance in the formulation of goals and scopes of criticality studies, the selection of adequate indicators and aggregation methods, and the interpretation of the outcomes, are important initial steps in improving the quality of criticality assessments. © 2019 Published by Elsevier B.V.Veröffentlichung Internationale Umwelt- und Nachhaltigkeitspolitik während und nach der Covid-19-Pandemie(2020) Ginzky, Harald; Kosmol, Jan; Schwirn, KathrinVeröffentlichung The path to a globally just circular economy(2023) Janz, Alexander; Kosmol, Jan; Messner, Dirk
