Description: Global warming, the overall extraction of minerals and the expansion of cultivated land for biomass harvest are growing globally. These "Big Three" represent key environmental pressures which may lead to a continuous degradation of the living environment, if not controlled at levels with acceptable low risk. The situation is complex, because countries and regions consume products which require resources such as minerals and land in various parts of the world. Nevertheless, it is possible to measure the global resource use which is associated with the domestic consumption. In order to inform policies at the national and supranational level whether it may be necessary to adjust the incentive framework for industry and households, reference data are needed to compare the status quo of their countries with what may be deemed acceptable at a global level. This chapter outlines a rationale for the derivation of possible long-term targets for total material consumption of abiotic materials (TMCabiot) and global land use for crops (GLUcropland). The indicated targets are expressed in tentative per capita values which may serve as a first orientation and basis for further debate and research.

Description: EXIOPOL (A New Environmental Accounting Framework Using Externality Data and Input–Output Tools for Policy Analysis) was a European Union (EU)-funded project creating a detailed, global, multiregional environmentally extended Supply and Use table (MR EE SUT) of 43 countries, 129 sectors, 80 resources, and 40 emissions. We sourced primary SUT and input–output tables from Eurostat and non-EU statistical offices. We harmonized and detailed them using auxiliary national accounts data and co-efficient matrices. Imports were allocated to countries of exports using United Nations Commodity Trade Statistics Database trade shares. Optimization procedures removed imbalances in these detailing and trade linking steps. Environmental extensions were added from various sources. We calculated the EU footprint of final consumption with resulting MR EE SUT. EU policies focus mainly on energy and carbon footprints. We show that the EU land, water, and material footprint abroad is much more relevant, and should be prioritized in the EU's environmental product and trade policies.

Description: The European Waste Framework Directive has defined waste prevention as top of the waste hierarchy meaning nothing less than a fundamental change of the sociotechnical system of waste infrastructures with all its economic, legal, social and cultural elements. Based on an empirical analysis of more than 300 waste prevention measures this paper assesses which prevention effects can realistically be achieved by applying the measures described in the German waste prevention programme or in those of other EU member states. Taking into account waste streams like packaging, food waste, bulky waste and production waste the results show that waste generation is not an unavoidable evil but can be significantly reduced at current level of technology.

Description: A desirable future critically depends on our ability to ensure the supply of key resources while simultaneously respecting planetary boundaries. This paper looks at the potential implications of living within the "safe operating space" for people, business and the economy. It develops a positive vision of the future based on three pillars: a safe and fair use of global resources, a sustainable society, and a transformed economy. We review and build on recent sustainability visions to develop a holistic reflection on what life in 2050 could look like, and explore the key changes in the economy needed to get there. In particular we show that resource efficiency requires a systemic shift in values, innovation, governance and management regimes. We present a bold vision for Europe underlined by indicators and targets, explore transition challenges to getting there and conclude with a list of key policies needed for overcoming challenges and reaching the vision.

Description: While strategic studies on natural resources usually focus on the criticality of certain single materials, our paper starts from the inter-linkages between and among resources (called "the resource nexus"). It examines the impact any food and water stress may have on extraction activities in fragile states and regions. According to our approach, conflicts are likely to increase and may escalate in a number of countries, many of which are of relevance for the global supply of strategic materials. Future criticality for European and other industries, thus, is more likely to result from particular regions surpassing their adaptive capacities, and not mainly from limited availability or bottlenecks in the supply chain. The paper first develops a heuristic model of drivers for stress in resource-rich regions. Applying this approach, our paper then develops a global three-layered map along the dimensions of (i) future regional food and water stress, (ii) fragility of countries, and (iii) resource-rich countries with relevant reserves of strategic materials. As a result our paper tentatively identifies 15 countries at high risk and some 30 other countries being at relevant risk of causing resource supply disruptions. The conclusions underline the need to analyse those global inter-linkages and institutional mechanisms for strategic futures studies at a regional scale. As this may go beyond the capacities of actors on commodity markets, our paper also draws conclusions towards the establishment of an international data hub on the global resource nexus and for futures research. The paper points to some of the long-term implications of these issues.

Description: Living Labs for Sustainable Development aim to integrate users and actors for the successful generation of low-resource innovations in production-consumption systems. This paper investigates potentials of and measures towards the realization of a German Living Lab infrastructure to support actor-integrated sustainability research and innovations in Germany. Information was primarily derived from extensive dialog with experts from the fields of innovation, sustainable development and the Living Lab community (operators, users, etc.), which was facilitated through interviews and workshops. A status quo analysis revealed that, generally, the sustainability and Living Lab communities are hardly intertwined. Twelve Living Labs that explicitly consider sustainability aspects were identified. The application fields "Living and Working", "Town, Region and Mobility", and “Retail and Gastronomy" were identified as particularly suitable for investigation in Living Labs and highly relevant in terms of resource efficiency. Based on the analyses of drivers and barriers and SWOT, keystones for the development of a research infrastructure for user integrated development of sustainable products and services were formulated. Suggested strategies and measures include targeted funding programs for actor-integrated, socio-technical research based on a Living Lab network, a communication campaign, and programs to foster networking and the inclusion of SMEs.

Description: The paper suggests a sustainable material footprint of eight tons, per person, in a year as a resource cap target for household consumption in Finland. This means an 80% (factor 5) reduction from the present Finnish average. The material footprint is used as a synonym to the Total Material Requirement (TMR) calculated for products and activities. The paper suggests how to allocate the sustainable material footprint to different consumption components on the basis of earlier household studies, as well as other studies, on the material intensity of products, services, and infrastructures. It analyzes requirements, opportunities, and challenges for future developments in technology and lifestyle, also taking into account that future lifestyles are supposed to show a high degree of diversity. The targets and approaches are discussed for the consumption components of nutrition, housing, household goods, mobility, leisure activities, and other purposes. The paper states that a sustainable level of natural resource use by households is achievable and it can be roughly allocated to different consumption components in order to illustrate the need for a change in lifestyles. While the absolute material footprint of all the consumption components will have to decrease, the relative share of nutrition, the most basic human need, in the total material footprint is expected to rise, whereas much smaller shares than at present are proposed for housing and especially mobility. For reducing material resource use to the sustainable level suggested, both social innovations, and technological developments are required.

Description: Despite rising prices for natural resources during the past 30 years, global consumption of natural resources is still growing. This leads to ecological, economical and social problems. So far, however, limited effort has been made to decrease the natural resource use of goods and services. While resource efficiency is already on the political agenda (EU and national resource strategies), there are still substantial knowledge gaps on the effectiveness of resource efficiency improvement strategies in different fields. In this context and within the project "Material Efficiency and Resource Conservation", the natural resource use of 22 technologies, products and strategies was calculated and their resource efficiency potential analysed. In a preliminary literature- and expert-based identification process, over 250 technologies, strategies, and products, which are regarded as resource efficient, were identified. Out of these, 22 subjects with high resource efficiency potential were selected. They cover a wide range of relevant technologies, products and strategies, such as energy supply and storage, Green IT, transportation, foodstuffs, agricultural engineering, design strategies, lightweight construction, as well as the concept "Using Instead of Owning". To assess the life-cycle-wide resource use of the selected subjects, the material footprint has been applied as a reliable indicator. In addition, sustainability criteria on a qualitative basis were considered. The results presented in this paper show significant resource efficiency potential for many technologies, products and strategies.

Description: In the light of the tremendous challenges facing the energy systems of the Middle East and North Africa (MENA), a number of concepts, roadmaps and scenario studies have emerged, describing potential transformation pathways towards a more sustainable, renewable-based, energy supply future in the region. Our article uses the scientific approach of "transition research" to analyze the most pertinent publications and concepts in this field to identify the key drivers and barriers for the transformation of the regional energy systems. The analysis likewise includes an assessment of possible indicators and indexes that can be used to monitor the sustainability of the transformation process of MENA energy systems.

Description: In many developing countries large parts of the population are negatively affected by the lack of access to clean and affordable energy. Providing sustainable energy services to these people has been acknowledged as a key component to reduce poverty. One form of development assistance to address the needs of the energy-poor at the local level are small-scale renewable energy projects. Like all development interventions, these energy projects are not intended to produce short-term outputs, but to create long-term impacts. Thus, it has become increasingly important to evaluate and accurately assess their sustainability. But despite the widely recognized need to identify successes factors and explain failure only few studies exist that address the sustainability of small-scale of energy development efforts post implementation. Against this background the paper presents the results of a post-evaluation of 23 projects supported via the Sustainable Energy Project Support (SEPS) scheme of the WISIONS initiative run by the Wuppertal Institute. The analysis provides insights on the influence that socio-economic, environmental, geographic and gender factors can have on the sustainability of small-scale renewable energy projects in developing countries.

Description: A key challenge of the 21st century is to transform society into one that features sustainable patterns of production and consumption. To achieve this, transition processes need to be designed in key areas such as housing, mobility and nutrition. The design and large-scale implementation of sustainable product service systems (PSS) is regarded a promising approach for sustainability transitions. Real-life socio-technical experiments are an important infrastructure for designing PSS in collaboration with stakeholders and users. In this paper, we argue that transdisciplinary and action research methods are required for institutionalising an experimental set-up and developing PSS within such infrastructures. We present the Sustainable LivingLabs (SLL) research infrastructure and its methodology as an example of such experimental settings. It was collaboratively developed with key stakeholders in three consecutive research projects and applied to e.g. heating and space heating. We show new qualities of SLL in relation to existing LivingLabs and approaches for PSS design and present its methodological three-phase model (insight research, prototyping, field testing) of research. Our article contributes to knowledge on a methodological framework and tool-kit for PSS development in SLL with a clear focus on socio-ecological sustainability. Intermediate findings confirm the high influence of user practices on heating energy consumption and show starting points for PSS development: e.g. transformational products, home-automation combined with consulting along value chains. We hypothesise that developing PSS in user- and stakeholder-integrated settings supports acceptance and diffusion and, by taking into account users' social practices of utilising novelties, reduces rebound effects caused by incorrect application.

Description: In this manual, the consortium wants to share the key lessons we have learnt throughout this three-year project and, by doing so, to contribute to the scaling-up of low carbon city development in emerging economies, especially in China. This manual targets organisations from the scientific and civil society sectors that are involved in international low carbon city projects, especially those with a focus on Chinese cities, as well as local govern-ments that are eager to develop a comprehensive low carbon strategy.

Description: The current flow of carbon for the production, use, and waste management of polymer-based products is still mostly linear from the lithosphere to the atmosphere with rather low rates of material recycling. In view of a limited future supply of biomass, this article outlines the options to further develop carbon recycling (C-REC). The focus is on carbon dioxide (CO2) capture and use for synthesis of platform chemicals to produce polymers. CO2 may be captured from exhaust gases after combustion or fermentation of waste in order to establish a C-REC system within the technosphere. As a long-term option, an external C-REC system can be developed by capturing atmospheric CO2. A central role may be expected from renewable methane (or synthetic natural gas), which is increasingly being used for storage and transport of energy, but may also be used for renewable carbon supply for chemistry. The energy input for the C-REC processes can come from wind and solar systems, in particular, power for the production of hydrogen, which is combined with CO2 to produce various hydrocarbons. Most of the technological components for the system already exist, and, first modules for renewable fuel and polymer production systems are underway in Germany. This article outlines how the system may further develop over the medium to long term, from a piggy-back add-on flow system toward a self-carrying recycling system, which has the potential to provide the material and energy backbone of future societies. A critical bottleneck seems to be the capacity and costs of renewable energy supply, rather than the costs of carbon capture.

Description: The availability of life cycle inventories is one of the biggest challenges for life cycle wide environmental assessment. There are several life cycle assessment (LCA) databases providing inventory data as well as resource and emission profiles of processes for impact assessment methods like ReCiPe or IMPACT 2002+. But the use of these LCA databases for input oriented environmental assessment is very limited as they cover only a part of all relevant input flows. The paper describes current challenges when calculating the input oriented Material Input per Service Unit (MIPS) indicators based on LCA inventory data from the Ecoinvent database. Propositions are made how to address these challenges. As a conclusion, further need of research to reach a full compatibility of LCA databases and the MIPS concept is pointed out.

Description: Within the scope of citizen science projects, crowdsourcing has already expanded into scientific application areas. In this, its scientific potential is only partly exhausted, however. It will be shown that transdisciplinary research is made up in content and structural aspects in such a way that crowdsourcing can fully unfold as a research method through varied participation possibilities, reflective processes and use of contemporary technical possibilities. Furthermore, mutual learning, understanding and the dissemination of knowledge strongly profits from effects that even result automatically in this context. The scientific application of crowdsourcing represented here makes high demands on project management, but it is expected to turn out as an effective research method precisely in the area of transdisciplinary research.

Description: In recent decades, better data and methods have become available for understanding the complex functioning of cities and their impacts on sustainability. This review synthesizes the recent developments in concepts and methods being used to measure the impacts of cities on environmental sustainability. It differentiates between a dominant trend in research literature that concentrates on the accounting and allocation of greenhouse gas emissions and energy use to cities and a reemergence of studies that focus on the direct and indirect material and resource flows in cities. The methodological approaches reviewed may consider cities as either producers or consumers, and all recognize that urban environmental impacts can be local, regional, or global. As well as giving an overview of the methodological debates, we examine the implications of the different approaches for policy and the challenges these approaches face in their application on the field.

Description: At current primary steel production levels, the iron and steel industry will fail to meet the 80% emission reduction target without introduction of breakthrough technologies (Wörtler et al., 2013: 19). The current research analyses the technical and economical long-term potential of innovative primary steel production technologies in Germany throughout 2100. Techno-economic models are used to simulate three innovative ore-based steelmaking routes verses the reference blast furnace route (BF-BOF). The innovative routes in focus are blast furnace with CCS (BF-CCS), hydrogen direct reduction (H-DR), and iron ore electrolysis (EW). Energy and mass flows for the production of one tonne of crude steel (CS) are combined with hypothetical price, cost, and revenue data to evaluate the production routes economically, technically, and environmentally. This is a purely theoretical analysis and hence further external factors that may influence practical implementation or profitability are not considered. Different future developments are considered by using three scenarios, representing an ambitious, a moderate, and a conservative transformation of the German energy sector. In general, looking into the future bares various uncertainties which should be reflected in a suitable manner. According to the present scenario analysis, chances are that with rising prices for coal and CO2 allowances BF-BOF and even BF-CCS become unprofitable by mid-century. With a high share of renewable energy sources and high prices for CO2 allowances, H-DR and EW become economically attractive in the second half of the current century, when BF-based routes are long unprofitable. Energy and raw material efficiency is significantly higher for H-DR and EW and furthermore, the 80% reduction target by 2050 can be achieved in the ambitious scenario. However, high investment costs and high dependency on electricity prices prohibit a profitable implementation before 2030–2040 without further subsidies. EW is the most energy and resource efficient production route. Since continuous electricity is needed for the continuous operation, the electricity costs are 20–40% higher than for H-DR (with high-capacity hydrogen storage units). Even though hydrogen production implies efficiency losses compared to the EW route, the decoupling of hydrogen production from continuous operation of the steel plant through hydrogen storage offers the opportunity to use cheap excess renewable electricity. This makes the H-DR economically and environmentally the most attractive route and provides a crucial contribution to stabilize the grid and to store excess energy in a 100% renewable energy system.

Description: This report details current and potential recycling of critical metals in Waste from Electrical Electronic Equipment (WEEE). The term "critical metals" is used instead of "rare metals" because the concept incorporates not only supply but also demand. The EU needs access to these metals and recycling can be an important part of the supply-strategy. The study shows that the current recycling of critical metals in WEEE is very low, but that the potential amount could be increased threefold within 2015. Improving of the recycling of critical metals requires a variety of initiatives tackling different week point in the overall process: better collection, better pre-processing and end-processing, limiting the export of WEEE or used products out of the EU and better design of the EEE-products. This study shows that data on sales volumes, WEEE composition and the composition of critical metals in EEE is currently insufficient for detailed analysis and monitoring, and addressing this should be a priority. Further, more detailed information on components used in EEE product groups would enable recyclers to identify and access the most materially important components. Dialog between recyclers, smelters and manufacturers could also facilitate product design that supports the recycling process.

Description: Urbanization and climate change are amongst the greatest challenges of the 21st century. In the "Low Carbon Future Cities" project (LCFC), three important problem dimensions are analysed: current and future GHG emissions and their mitigation (up to 2050); resource use and material flows; and vulnerability to climate change. The industrial city of Wuxi has been the Chinese pilot city of the project. To establish the pathway for a low carbon future, it is crucial to understand the current situation and possible future developments. The paper presents the key results of the status quo analysis and the future scenario analysis carried out for Wuxi. Two scenarios are outlined. The Current Policy Scenario (CPS) shows the current most likely development in the area of energy demand and GHG emissions until 2050. Whereas the extra low carbon scenario (ELCS) assumes a significantly more ambitious implementation, it combines a market introduction of best available technologies with substantial behavioural change. All scenarios are composed of sub-scenarios for the selected key sectors. Looking at the per capita emissions in Wuxi, the current levels are already high at around 12 tonnes CO2 per capita compared to Western European cities. Although Wuxi has developed a low carbon plan, the projected results under current policies (CPS) show that the total emissions would increase to 23.6 tonnes CO2 per capita by 2050. If the ELCS pathway was to be adopted, these CO2 emission levels could be reduced to 6.4 tonnes per capita by 2050.
