Veröffentlichung A resource efficient and greenhouse gas neutral Germany 2050(2018) Günther, Jens; Nuss, Philip; Nissler, Diana; Purr, KatjaVeröffentlichung A resource efficient pathway towards a greenhouse gas neutral Germany(2019) Günther, Jens; Butz, Wolfgang; Lorenz, Ullrich; Fee, Eric; Herbener, Reinhard; Döring, Ulrike; Hermann, Tim; Hofmeier, Katja; Kessler, Kai; Knoche, Guido; Kosmol, Jan; Kristof, Kora; Koller, Matthias; Lange, Martin; Lehmann, Harry; Lambrecht, Martin; Leprich, Uwe; Mönch, Lars; Nuss, Philip; Obermaier, Nathan; Pfeiffer, David; Plickert, Sebastian; Purr, Katja; Rechenberg, Bettina; Schmied, Martin; Schuberth, Jens; Seven, Jan; Starke, Sue-Martina; Werlein, Max; Deutschland. Umweltbundesamt. Fachgebiet I.2.1 - Internationaler Klimaschutz; Deutschland. UmweltbundesamtThe study shows that it is possible to transform Germany to both greenhouse gas neutral and resource efficient. One side of the balance is greenhouse gas and raw material saving due to exit from fossil energy carriers and the other is the increased raw material use for the construction of the renewable energy system. In the “GreenEe” scenario it is possible to reduce the GHG emissions in 2050 by 95 % compared to 1990 and the raw material consumption (RMC) by almost 60 % compared to 2010. The study shows also that related ambitious climate and resource efficiency policies helps to achieve both goals. Considering both policy field in a systemic way, should be further discussed and implemented in future politics.Veröffentlichung 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 Analysis of the circular material use rate and the doubling target(2023) Christis, Maarten; Vercalsteren, An; Nuss, Philip; European Environment AgencyThis report analyses the progress made by the European Union (EU) in the circular material use rate (CMUR), supporting a better understanding of the observed status and trends. In addition, it provides a first simplified assessment of the prospects of the EU to move towards its ambition to double the CMUR within a decade, in the context of the Circular Economy Action Plan (CEAP) and the European Green Deal (EGD). Broadening the scope, the report looks also into unaccounted flows of recycled materials, a key driver of CMUR. It also complements the CMUR assessment by quantifying environmental impacts linked to material consumption, the main current driver of CMUR. This analysis helps to understand and interpret the observed status, trends and possible future developments for the CMUR, both on the total CMUR as well as on the CMUR for the four broad material categories as published by Eurostat. The insights are considered in the context of the CEAPâ€Ìs aim of "doubling the CMUR in the coming decade" at the EU level. The integration of the environmental impact from material uses brings in different perspectives into the analysis and interpretation of the CMUR. © European Topic Centre on Circular economy and resource use, 2023Veröffentlichung Chancen und Grenzen des Recyclings im Kontext der Circular Economy(Ressourcenkommission am Umweltbundesamt, 2023) Hagelüken, Christian; Schmidt, Mario; Schebek, Liselotte; Deutschland. Umweltbundesamt; Umweltbundesamt. Ressourcenkommission; Nuss, PhilipCircular Economy hat neben ökologischen und klimapolitischen Zielen auch eine wichtige Bedeutung zur Stärkung der Versorgungssicherheit sowie zur Erreichung weiterer wirtschaftspolitischer und sozio-ökonomischer Ziele. Recycling ist dabei eine der Stellschrauben zusammen mit einer Reihe weiterer Ansätze und Strategien (z.B. Langlebigkeit, Nutzungsintensität und Sharing Economy). Um den Beitrag sowie die Grenzen von Recycling für Ressourcenschonung und Klimaschutz zu bewerten, bedarf es einer klaren Benennung des Betrachtungsrahmens und von Systemgrenzen sowie präzise ausformulierter Berechnungsansätze und Indikatoren. Die Ressourcenkommission am Umweltbundesamt (KRU) fasst in diesem Papier den aktuellen Wissensstand zum Recycling zusammen und empfiehlt mögliche Indikatoren mit einem Fokus auf Metalle, welche eine Schlüsselrolle für die Energie- und Klimawende innehaben.

One approach for obtaining data on the intersectoral exchanges of materials in an economy is with physical input-output tables (PIOTs). Using PIOTs of eleven alloying metals (aluminum, vanadium, chromium, manganese, iron, cobalt, nickel, copper, niobium, molybdenum, tungsten) for the entire United States economy in 2007, we apply network-based metrics and visualizations to identify key sectors and compare different PIOTs with each other. Some 40-45% of all intersectoral trade contains the major metals aluminum, copper, and iron, while this number ranges between only 11-15% for minor metals (e.g., cobalt, vanadium, niobium, molybdenum, tungsten). The majority of sectors rely on products containing the major metals, reflecting widespread use of those products in our modern economy. Network size provides an indication of supply chain steps required to move from metal production to finished product manufacturing. Supply chains for the minor metals require an average of 5-8 steps, while those of major metals involve 3 steps on average. Cobalt is used extensively to illustrate these results because its status as a "technology-critical material" demonstrates how these analytical approaches can reveal sector usage and dependency for a metal of potential supply concern. We conclude by presenting automobile supply chain networks and discuss the position of the automobile production sector in the US economy. The analytical and visualization approaches presented result in an improved understanding of metal flows and can help to better communicate underlying data, e.g., in a policy context. © 2019 Elsevier B.V.

UmweltbundesamtDie Studie zeigt, dass es möglich ist, Deutschland sowohl treibhausgasneutral als auch ressourcenschonend umzugestalten. Den Einsparungen von Treibhausgasen und Rohstoffen durch den Ausstieg aus fossilen Energieträgern steht die erhöhte Rohstoffinanspruchnahme für den Aufbau des erneuerbare Energiesystems gegenüber. Im vorgestellten „GreenEe“-Szenario gelingt es, die Treibhausgasemissionen um 95 Prozent gegenüber 1990 und die Primär-Rohstoffinanspruchnahme um 60 Prozent gegenüber 2010 bis 2050 zu senken. Die Studie zeigt, dass ein verbundener ambitionierter Klima- und Ressourcenschutz hilft, beide Ziele zu erreichen. Eine solche systemische Vorgehensweise sollte künftig stärker diskutiert und realisiert werden.Veröffentlichung Den Weg zu einem treibhausgasneutralen Deutschland ressourcenschonend gestalten(2019) Günther, Jens; Lehmann, Harry; Nissler, Diana; Nuss, Philip; Purr, KatjaVeröffentlichung Greater circularity leads to lower criticality, and other links between criticality and the circular economy(2020) Espinoza, LuisTercero; Schrijvers, Dieuwertje; Chen, Wei-Qiang; Nuss, PhilipVeröffentlichung Indikatoren im Themenfeld Ressourcenschonung und Circular Economy(Umweltbundesamt, 2024) Schebek, Liselotte; Dosch, Klaus; Faulstich, Martin; Hagelüken, Christian; Jaeger-Erben, Melanie; Nuss, Philip; Schmidt, Mario; Ressourcenkommission am Umweltbundesamt; UmweltbundesamtHeute finden sich in der wissenschaftlichen Literatur, in Studien und in Politikprogrammen eine Vielzahl von Ressourcen- und Circular Economy (CE)-Indikatoren auf Basis unterschiedlicher konzeptioneller und methodischer Ansätze. Um die Auswahl von geeigneten Indikatoren zu erleichtern, enthält das vorliegende Positionspapier zwei Teile: Im Teil I werden Leitlinien für Indikatoren und Indikatorensysteme vorgestellt, welche die Einordnung vorhandener CE-Indikatoren im Hinblick auf ihre Funktion und Aussagekraft ermöglichen als auch die (Weiter-)Entwicklung zielorientierter und konsistenter Indikatorensysteme unterstützen. Im Teil II werden die Grundlagen der Indikatorik ausführlich und auf Basis der wissenschaftlichen Literatur dargestellt und ein Überblick zu relevanten Ressourcen- und CE-Indikatoren gegeben.Veröffentlichung Losses and environmental aspects of a byproduct metal: tellurium(2019) Nuss, PhilipGlobal demand for tellurium has greatly increased owing to its use in solar photovoltaics. Elevated levels of tellurium in the environment are now observed. Quantifying the losses from human usage into the environment requires a life-cycle wide examination of the anthropogenic tellurium cycle (in analogy to natural element cycles). Reviewing the current literature shows that tellurium losses to the environment might occur predominantly as mine tailings, in gas and dust and slag during processing, manufacturing losses, and in-use dissipation (situation in around 2010). Large amounts of cadmium telluride will become available by 2040 as photovoltaic modules currently in-use reach their end-of-life. This requires proper end-of-life management approaches to avoid dissipation to the environment. Because tellurium occurs together with other toxic metals, e.g. in the anode slime collected during copper production, examining the life-cycle wide environmental implication of tellurium production requires consideration of the various substances present in the feedstock as well as the energy and material requirements during production. Understanding the flows and stock dynamics of tellurium in the anthroposphere can inform environmental chemistry about current and future tellurium releases to the environment, and help to manage the element more wisely.

There is a rapidly evolving debate on definitions, limitations, the contribution to a wider sustainability agenda, and a need for indicators to assess the effectiveness of circular economy measures at larger scales. Herein, we present a framework for a comprehensive and economy-wide biophysical assessment of a CE, utilizing and systematically linking official statistics on resource extraction and use and waste flows in a mass-balanced approach. This framework builds on the widely applied framework of economy-wide material flow accounting and expands it by integrating waste flows, recycling, and downcycled materials. We propose a comprehensive set of indicators that measure the scale and circularity of total material and waste flows and their socioeconomic and ecological loop closing. We applied this framework in the context of monitoring efforts for a CE in the European Union (EU28) for the year 2014. We found that 7.4 gigatons (Gt) of materials were processed in the EU and only 0.71 Gt of them were secondary materials. The derived input socioeconomic cycling rate of materials was therefore 9.6%. Further, of the 4.8 Gt of interim output flows, 14.8% were recycled or downcycled. Based on these findings and our first efforts in assessing sensitivity of the framework, a number of improvements are deemed necessary: improved reporting of wastes, explicit modeling of societal in-use stocks, introduction of criteria for ecological cycling, and disaggregated mass-based indicators to evaluate environmental impacts of different materials and circularity initiatives. © 2019 The AuthorsVeröffentlichung Mehr mit weniger - ein Weg zur ressourcenschonenden Treibhausgasneutralität?(2020) Günther, Jens; Nuss, Philip; Purr, KatjaVeröffentlichung Mineral Resource Governance in the 21st Century(UNEP, 2020) Ayuk, Elias T.; Pedro, Antonio M.; Ekins, Paul; Nuss, Philip; United Nations Environment ProgrammeResources, including minerals and metals, underpin the world's economies for almost all sectors, providing crucial raw materials for their industrial processes. Despite efforts to decouple economies from resource use towards a circular economy, demand for extractive resources will continue to grow on the back of emerging economies. The report maps existing international governance frameworks and initiatives which have overlapping subsets that focus on delivering the 2030 Global Agenda for Sustainable Development. In this report, the International Resource Panel (IRP) of the UN Environment Programme highlights that the mining sector, if carefully managed, presents enormous opportunities for advancing sustainable development, particularly in low-income countries. As discussed in Chapter 5, extractive industries place large demands on natural resources such as land and water. Its activities can lead to polluting water resources, biodiversity loss and ecosystem destruction including land degradation and desertification. Therefore, there is a need to look at the dynamic relationships between mining, and land and water. This calls for a systems-thinking approach that accounts for the nexus between resources so as to steer policy efforts towards integrated natural resource management along the mining value chain. The report maps existing international governance frameworks and initiatives which have overlapping subsets that focus on delivering the 2030 Global Agenda for Sustainable Development. It presents the practical actions required to improve the international governance architecture for mining to enhance its contribution towards sustainable development. It calls for a new governance framework for the extractive sector referred to as the "Sustainable Development Licence to Operate" which includes consensus-based principles, policy options and best practices that are compatible with the Sustainable Development Goals and other international policy commitments. Minerals and metals underpin national economies, provide crucial raw materials for industrial activities, and are inputs to almost every sector of the global economy. Demand for extractive resources will continue to grow on the back of emerging economies with expanding and increasingly affluent and urban populations and a global transition towards low-carbon but metal-intensive energy production technologies. This is despite efforts to decouple economies from resource use and towards greater recycling. The frequently severe and enduring environmental impacts of mining highlight the need to carefully balance such activities with stewardship of other valuable natural resources and the environment including ecosystems and biodiversity, and the rights of local people and communities. Decision-making in the extractive sector is shaped by a complex array of governance frameworks and initiatives operating along highly globalized mineral value chains. There is an urgent need to coordinate and reform this governance landscape to address enduring challenges such as commodity price volatility, lack of linkages between mining and other economic sectors, inadequate management of environmental impact, and socio- and geopolitical risks of mining. The report maps over 80 existing international governance frameworks and initiatives which focus on delivering overlapping subsets of the 2030 Global Agenda for Sustainable Development, but do not currently operate in a sufficiently coordinated or integrated manner. In this context, the report calls for a new governance framework for the extractive sector referred to as the "Sustainable Development Licence to Operate" and includes consensusbased principles, policy options and best practices that are compatible with the Sustainable Development Goals and other international policy commitments. The report discusses practical actions to improve the international governance architecture for mining to enhance its contribution towards sustainable development. The proposals include reaching an international consensus regarding the normative content and structure of the Sustainable Development Licence to Operate informed by expert inputs from a "Highlevel Panel on Mining for Sustainable Development". It further considers the creation of an International Mineral Agency to share relevant information and data. Governments could also reach bilateral and plurilateral agreements regarding security of supply of raw materials and resource-driven development. Periodical reporting of progress towards sustainable development could be enabled through a Global "State of the Extractive Sector" review or equivalent process. Quelle: VerlagsinformationVeröffentlichung 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 Monitoring the consumption footprint of countries to support policy-making: An assessment of data availability in Germany(2023) Nuss, Philip; Sanyé-Mengual, Esther; Sala, SerenellaThe European Green Deal and the German Resource Efficiency Programme both aim at decoupling resource consumption and associated environmental burdens from economic growth. Monitoring the progress of such policies requires robust estimates of environmental pressures and impacts, both from a domestic and a footprint perspective. Building on the life cycle assessment-based consumption footprint (CoF) indicator, developed by the European Commission Joint Research Centre, we assess the environmental impacts of Germany's consumption in the areas of food, mobility, housing, household goods, and appliances during the period 2010â€Ì2018. A comparison between European and national consumption statistics revealed some differences in terms of data composition, granularity, consumption intensities, and calculated environmental impacts. Using national data sources results in slightly lower environmental impacts (e.g., due to differences in the assessment scope of national statistics) and requires some data preparation to match the CoF indicator. Emerging consumption trends can be highlighted using national data. Both data sources converge on main trends: Germany transgresses the safe operating space for several impact categories, with consumption of food, household goods, and mobility being the main drivers. Domestic impacts have decreased over time at the expense of outsourcing environmental pressures and impacts to other countries. The CoF indicator could complement resource monitoring frameworks and might be further aligned to the national context using country-level consumption statistics and life cycle inventory data.

Ressourcenkommission; Deutschland. Umweltbundesamt; Nuss, PhilipIn addition to environmental and climate policy objectives, the Circular Economy is also essential for strengthening the security of supply and for achieving further economic and socio-economic goals. Recycling is one of the key factors along with a range of other approaches and strategies (e.g., longevity, Intensity of use, and the sharing economy). In order to assess the contribution and the limits of recycling for sustainable resource use and climate protection, there is a need for a clear definition of the assessment framework and system boundaries, as well as for precisely formulated calculation approaches and indicators. In this paper, the Resource Commission at the German Environment Agency (KRU) summarizes the current state of knowledge on recycling and recommends possible indicators with a focus on metals, which play a key role in the energy transition and for climate protection. Quelle: umweltbundesamt.deVeröffentlichung Pathways to a resource-efficient and greenhouse-gas-neutral Germany(2020) Günther, Jens; Nuss, Philip; Lehmann, Harry; Purr, KatjaGlobal greenhouse gas (GHG) emissions continue to rise despite the implementation of climate protection measures. Global materials extraction is accelerating and contributes significantly to GHG-emissions and other environmental pressures. Raw materials such as metals, biomass, and non-metallic minerals are central in meeting the climate targets by 2050. This study investigates possible transformation pathways towards a GHG-neutral and resource-efficient Germany by 2050 using six scenarios. In all scenarios, a transformation towards 100% renewable energy (electricity, fuels, and feedstocks) takes place until 2050. By 2050, GHG-reductions of 95% to 97% is achieved compared to 1990. Raw materials consumption can be reduced by 56% to 70% compared to 2010. However, the demand for a range of metals central to the transformation will also increase. The results show that ambitious efforts and cross-sectoral cooperation at both national and international level are required to mitigate climate change and lower raw materials demands.
