Description: Environmentally extended multiregional input-output (EE MRIO) tables have emerged as a key framework to provide a comprehensive description of the global economy and analyze its effects on the environment. Of the available EE MRIO databases, EXIOBASE stands out as a database compatible with the System of Environmental-Economic Accounting (SEEA) with a high sectorial detail matched with multiple social and environmental satellite accounts. In this paper, we present the latest developments realized with EXIOBASE 3 - a time series of EE MRIO tables ranging from 1995 to 2011 for 44 countries (28 EU member plus 16 major economies) and five rest of the world regions. EXIOBASE 3 builds upon the previous versions of EXIOBASE by using rectangular supply-use tables (SUTs) in a 163 industry by 200 products classification as the main building blocks. In order to capture structural changes, economic developments, as reported by national statistical agencies, were imposed on the available, disaggregated SUTs from EXIOBASE 2. These initial estimates were further refined by incorporating detailed data on energy, agricultural production, resource extraction, and bilateral trade. EXIOBASE 3 inherits the high level of environmental stressor detail from its precursor, with further improvement in the level of detail for resource extraction. To account for the expansion of the European Union (EU), EXIOBASE 3 was developed with the full EU28 country set (including the new member state Croatia). EXIOBASE 3 provides a unique tool for analyzing the dynamics of environmental pressures of economic activities over time.

Description: Combined heat and power (CHP) production in buildings is one of the mitigation options available for achieving a considerable decrease in GHG emissions. Micro-CHP (mCHP) fuel cells are capable of cogenerating electricity and heat very efficiently on a decentralised basis. Although they offer clear environmental benefits and have the potential to create a systemic change in energy provision, the diffusion of mCHP fuel cells is rather slow. There are numerous potential drivers for the successful diffusion of fuel cell cogeneration units, but key economic actors are often unaware of them. This paper presents the results of a comprehensive analysis of barriers, drivers and business opportunities surrounding micro-CHP fuel-cell units (up to 5 kWel) in the German building market. Business opportunities have been identified based not only on quantitative data for drivers and barriers, but also on discussions with relevant stakeholders such as housing associations, which are key institutional demand-side actors. These business opportunities include fuel cell contracting as well as the development of a large lighthouse project to demonstrate the climate-neutral, efficient use of fuel cells in the residential building sector. The next step could involve the examination and development of more detailed options and business models. The approach and methods used in the survey may be applied on a larger scale and in other sectors.

Description: The global energy system is undergoing a major transition, and in energy planning and decision-making across governments, industry and academia, models play a crucial role. Because of their policy relevance and contested nature, the transparency and open availability of energy models and data are of particular importance. Here we provide a practical how-to guide based on the collective experience of members of the Open Energy Modelling Initiative (Openmod). We discuss key steps to consider when opening code and data, including determining intellectual property ownership, choosing a licence and appropriate modelling languages, distributing code and data, and providing support and building communities. After illustrating these decisions with examples and lessons learned from the community, we conclude that even though individual researchers' choices are important, institutional changes are still also necessary for more openness and transparency in energy research.

Description: Access to clean and affordable modern energy services has been widely recognised as a significant factor for enabling social and economic development. Stand-alone systems and mini-grids are presumed to play an important role in the provision of sustainable energy to those people who currently lack access. Accordingly, an increasing number of small-scale energy projects are being implemented in developing countries and emerging economies. However, despite the large number of energy development projects, only limited evidence exists about the actual contribution they make to sustainable development. This paper addresses this research gap by providing a systematic assessment of three selected impact pathways based on the evaluation of over 30 small-scale sustainable energy projects. Applying a theory-based evaluation approach in the form of a contribution analysis, the aim of this research is to better understand if and how these types of technical interventions can create development outcomes and impacts. The results show that technological issues are often not the most decisive factor in achieving development effects, but that embedding the technology in a set of actions that address social, cultural, economic and environmental aspects is essential.

Description: Against the background of an often wasteful use of natural resources, the European Union has made resource efficiency a top policy priority. Policy formulation is, however, at a very early stage in many Member States, with often vague notions of what resource efficiency means, characterised by fragmented instruments and overlapping competencies. This paper develops a conceptual framework for defining, assessing and developing resource efficiency policy mixes. It argues that a mix of policies and instruments is best suited to overcoming the complex challenges of the 21st Century. Such a mix addresses multiple resource domains at a strategic, high level and contains interacting instruments targeting multiple actors, levels of governance and sectors and life-cycle stages of resource use. This paper looks at criteria for effective resource efficiency policy instruments, presents both an indicative policy mix across 9 policy domains and case studies (on environmental harmful subsidies, supply chain efficiency in food systems and product-service systems) and identifies key challenges to overcome trade-offs in instrument design, maximise synergies, reduce conflicts, promote coherence, coordinate activities and move from theory to practice. Research needs are discussed regarding who shall devise, implement, and coordinate such a policy mix, considering negotiating power, timing and complexity.

Description: Transition modelling is an emerging but growing niche within the broader field of sustainability transitions research. The objective of this paper is to explore the characteristics of this niche in relation to a range of existing modelling approaches and literatures with which it shares commonalities or from which it could draw. We distil a number of key aspects we think a transitions model should be able to address, from a broadly acknowledged, empirical list of transition characteristics. We review some of the main strands in modelling of socio-technological change with regards to their ability to address these characteristics. These are: Eco-innovation literatures (energy-economy models and Integrated Assessment Models), evolutionary economics, complex systems models, computational social science simulations using agent based models, system dynamics models and socio-ecological systems models. The modelling approaches reviewed can address many of the features that differentiate sustainability transitions from other socio-economic dynamics or innovations. The most problematic features are the representation of qualitatively different system states and of the normative aspects of change. The comparison provides transition researchers with a starting point for their choice of a modelling approach, whose characteristics should correspond to the characteristics of the research question they face. A promising line of research is to develop innovative models of co-evolution of behaviours and technologies towards sustainability, involving change in the structure of the societal and technical systems.

Description: The water-energy-food (WEF) nexus is increasingly recognised as a conceptual framework able to support the efficient implementation of the Sustainable Development Goals (SDGs). Despite growing attention paid to the WEF nexus, the role that renewable energies can play in addressing trade-offs and realising synergies has received limited attention. Until now, the focus of WEF nexus discussions and applications has mainly been on national or global levels, macro-level drivers, material flows and large infrastructure developments. This overlooks the fact that major nexus challenges are faced at local level. Aiming to address these knowledge gaps, the authors conduct a systematic analysis of the linkages between small-scale energy projects in developing countries and the food and water aspects of development. The analysis is based on empirical data from continuous process and impact evaluations complemented by secondary data and relevant literature. The study provides initial insights into how to identify interconnections and the potential benefits of integrating the nexus pillars into local level projects in the global south. The study identifies the complex links which exist between sustainable energy projects and the food and water sectors and highlights that these needs are currently not systematically integrated into project design or project evaluation. A more systematic approach, integrating the water and food pillars into energy planning at local level in the global south, is recommended to avoid trade-offs and enhance the development outcomes and impacts of energy projects.

Description: The Paris Agreement calls on all nations to pursue efforts to contribute to limiting the global temperature increase to 1.5 °C above pre-industrial levels. However, due to limited global, regional and country-specific analysis of highly ambitious GHG mitigation pathways, there is currently a lack of knowledge about the transformational changes needed in the coming decades to reach this target. Through a meta-analysis of mitigation scenarios for Germany, this article aims to contribute to an improved understanding of the changes needed in the energy system of an industrialized country. Differentiation among six key long-term energy system decarbonization strategies is suggested, and an analysis is presented of how these strategies will be pursued until 2050 in selected technologically detailed energy scenarios for Germany. The findings show, that certain strategies, including the widespread use of electricity-derived synthetic fuels in end-use sectors as well as behavioral changes, are typically applied to a greater extent in mitigation scenarios aiming at high GHG emission reductions compared to more moderate mitigation scenarios. The analysis also highlights that the pace of historical changes observed in Germany between 2000 and 2015 is clearly insufficient to adequately contribute to not only the 1.5 °C target, but also the 2 °C long-term global target.

Description: New energy technologies may fail to make the transition to the market once research funding has ended due to a lack of private engagement to conclude their development. Extending public funding to cover such experimental developments could be one way to improve this transition. However, identifying promising research and development (R&D) proposals for this purpose is a difficult task for the following reasons: Close-to-market implementations regularly require substantial resources while public budgets are limited; the allocation of public funds needs to be fair, open, and documented; the evaluation is complex and subject to public sector regulations for public engagement in R&D funding. This calls for a rigorous evaluation process. This paper proposes an operational three-staged decision support system (DSS) to assist decision-makers in public funding institutions in the ex-ante evaluation of R&D proposals for large-scale close-to-market projects in energy research. The system was developed based on a review of literature and related approaches from practice combined with a series of workshops with practitioners from German public funding institutions. The results confirm that the decision-making process is a complex one that is not limited to simply scoring R&D proposals. Decision-makers also have to deal with various additional issues such as determining the state of technological development, verifying market failures or considering existing funding portfolios. The DSS that is suggested in this paper is unique in the sense that it goes beyond mere multi-criteria aggregation procedures and addresses these issues as well to help guide decision-makers in public institutions through the evaluation process.

Description: The long-term transition towards a low-carbon transport sector is a key strategy in Europe. This includes the replacement of fossil fuels, modal shifts towards public transport as well as higher energy efficiency in the transport sector overall. While these energy savings are likely to reduce the direct greenhouse gas emissions of transport, they also require the production of new and different vehicles. This study analyses in detail whether final energy savings in the transport sector also induce savings for material resources from nature if the production of future vehicles is considered. The results for 28 member states in 2030 indicate that energy efficiency in the transport sector leads to lower carbon emissions as well as resource use savings. However, energy-efficient transport sectors can have a significant impact on the demand for metals in Europe. An additional annual demand for 28.4 Mt of metal ores was calculated from the personal transport sector in 2030 alone. The additional metal ores from semiprecious metals (e.g., copper) amount to 12.0 Mt, from precious metals (e.g., gold) to 9.1 Mt and from other metals (e.g., lithium) to 11.7 Mt, with small savings for ferrous metal ores (-4.6 Mt).

Description: Reliably reducing the emissions in the building sector plays a crucial role if the 1.5°C climate target from the Paris Agreement is to be met. The observed trends show a significant increase in building energy use, especially in emerging economies. Counteracting these trends is absolutely essential, especially in the light of urbanisation, population growth and changing lifestyles. In terms of mitigating the climate impact of buildings, ensuring high levels of efficiency (i.e. very low energy needs, especially for heating and cooling) has the greatest potential for saving energy and emissions, and is at the same time the prerequisite for effective use of energy from renewable sources. Clearly defined targets and suitable metrics are essential to enable appropriate design decisions. Implemented projects clearly indicate that quality assured design and construction lead to reliable in-use energy performance. Effective policy packages to address opportunities and challenges are important drivers to support the uptake of state-of-the-art efficiency measures in the urban building sector.

Description: For many years, carbon capture and storage (CCS) has been discussed as a technology that may make a significant contribution to achieving major reductions in greenhouse gas emissions. At present, however, only two large-scale power plants capture a total of 2.4 Mt CO2/a. Several reasons are identified for this mismatch between expectations and realised deployment. Applying bibliographic coupling, the research front of CCS, understood to be published peer-reviewed papers, is explored to scrutinise whether the current research is sufficient to meet these problems. The analysis reveals that research is dominated by technical research (69%). Only 31% of papers address non-technical issues, particularly exploring public perception, policy, and regulation, providing a broader view on CCS implementation on the regional or national level, or using assessment frameworks. This shows that the research is advancing and attempting to meet the outlined problems, which are mainly non-technology related. In addition to strengthening this research, the proportion of papers that adopt a holistic approach may be increased in a bid to meet the challenges involved in transforming a complex energy system. It may also be useful to include a broad variety of stakeholders in research so as to provide a more resilient development of CCS deployment strategies.

Description: There is a strong trend towards research in society-based laboratories, especially in relation to sustainability. Semantic analysis reveals related discourses and emerging lines of inquiry, namely transformative potential, transdisciplinarity and learning. Real-world laboratories are a dynamic example of this research. Contributions of how to deepen and broaden their analysis are presented.

Description: Real-world laboratories (RwLs, German Reallabore) belong to a family of increasingly popular experimental and transdisciplinary research approaches at the science-society interface. As these approaches in general, and RwLs in particular, often lack clear definitions of key characteristics and their operationalization, we make two contributions in this article. First, we identify five core characteristics of RwLs: contribution to transformation, experimental methods, transdisciplinary research mode, scalability and transferability of results, as well as scientific and societal learning and reflexivity. Second, we compare RwLs to similar research approaches according to the five characteristics. In this way, we provide an orientation on experimental and transdisciplinary research for societal transformations, and reveal the contributions of this type of research in supporting societal change. Our findings enable learning across the different approaches and highlight their complementarities, with a particular focus on RwLs.

Description: Heat integration and industrial symbiosis have been identified as key strategies to foster energy efficient and low carbon manufacturing industries (see e.g. contribution of Working Group III in IPCC's 5th assessment report). As energy efficiency potentials through horizontal and vertical integration are highly specific by site and technology they are often not explicitly reflected in national energy strategies and GHG emission scenarios. One of the reasons is that the energy models used to formulate such macro-level scenarios lack either the necessary high technical or the spatial micro-level resolution or both. Due to this lack of adequate tools the assumed huge existing potentials for energy efficiency in the energy intensive industry cannot be appropriately appreciated by national or EU level policies. Due to this background our paper describes a recent approach for a combined micro-macro energy model for selected manufacturing industries. It combines national level technical scenario modelling with a micro-modelling approach analogous to total site analysis (TSA), a methodology used by companies to analyse energy integration potentials on the level of production sites. Current spatial structures are reproduced with capacity, technical and energy efficiency data on the level of single facilities (e.g. blast furnaces) using ETS data and other sources. Based on this, both, the investments in specific technologies and in production sites are modelled and the evolvement of future structures of (interconnected) industry sites are explored in scenarios under different conditions and with different objectives (microeconomic vs. energy efficiency optimization). We further present a preliminary scenario that explores the relevance of these potentials and developments for the German steel industry.

Description: The German federal state of North Rhine-Westphalia (NRW) is home to important clusters of energy-intensive basic materials industries. 15% of the EU's primary steel as well as 15% of high-value base chemicals are produced here. Together with refinery fuels, cement, lime and paper production (also overrepresented in NRW) these are the most carbon-intensive production processes of the industrial metabolism. To achieve the ambitious regional and national climate goals without relocating these clusters, carbon-neutral production will have to become standard by mid-century. We develop and evaluate three conceptual long-term scenarios towards carbon-neutral industry systems for NRW for 2050 and beyond: * a first scenario depending on carbon capture and storage or use for heavy industries (iCCS), * a second scenario sketching the direct electrification of industrial processes (and transport) and * a third scenario relying on the import of low carbon energies (e.g. biomass, and synthetic fuels (like methanol) for the use in industries and transport. All scenarios share the assumption that electricity generation will be CO2-neutral by 2050. For all three scenarios energy efficiency, primary energy demand for energy services and feedstock as well as the carbon balance are quantified. We apply a spatial-explicit analysis of production sites to allow for discussion of infrastructure re-use and net investment needs. Possible symbiotic relations between sectors are also included. The robustness of the three conceptualised future carbon-neutral industry systems is then analysed using a multi-criteria approach, including e.g. energy security issues and lock-ins on the way to 2050.

Description: India's present development trajectory is at a crucial juncture with a requirement to meet the demands of a population of over 1.2 billion while ensuring environmental sustainability. The resulting economic growth over the past two decades has over-exploited finite natural resources and led to tremendous environmental degradation. Therefore, decoupling economic growth from resource consumption is crucial in the transformation towards a green economy. Building construction is one of the most resource-intensive sectors, as well as creating a high impact on the environment. This study analyzes existing mechanisms in India's building construction sector that attempt to decouple economic growth from resource use and environmental impacts. The key contributors for decoupling are analyzed. Recommendations for regulations, market incentives, transparency, data monitoring and capacity-building are provided for an array of policy initiatives targeted at political and financial decision-makers at the national, state and local levels for different buildings.

Description: There is an increasing pressure that enhanced and novel energy technologies are swiftly adopted by the market to ensure meeting the energy and climate targets. An important issue with such novel developments is their risk to be stuck in the "valley of death", i.e. that their transition to the market is delayed or unsuccessful. Publicly supported demonstration projects could help to bridge the valley of death by reducing barriers to the adoption caused by missing information and perceived risks. A challenge for technology demonstrations in the industrial context is their often high investments that are required to prove their real-world benefits. Given the magnitude of such investments, it becomes crucial that public funding focuses on the most promising demonstration proposals. Structured evaluation processes can help to facilitate the identification of promising proposals and to improve the quality and transparency of decisions. This paper deals with a corresponding multi-staged multi-criteria decision support system (DSS) suggested to the German Federal Ministry for Economic Affairs and Energy. It deals with the evaluation of demonstration proposals across three stages: The first stage represents a filtering stage to identify those proposals relevant for further considerations. The second stage comprises a multi-criteria scoring method drawing on an evaluation against nineteen criteria. The final third stage serves to critically review the need for public funding of well-scored proposals. This contribution outlines the development of the DSS and its design and thus provides insights on proposal evaluating in energy research.

Description: It is widely recognised that access to sustainable and affordable energy services is a crucial factor in reducing poverty and enhancing development. Accordingly, various positive effects beyond simple access to energy are associated with the implementation of sustainable energy projects. One of these assumed positive outcomes is the productive use of energy, which is expected to create value - for example in the form of increased local availability of goods or higher incomes - thereby having a positive impact on local livelihoods. Many projects and programmes are based on such expectations regarding the productive use of energy but systematic evidence of these outcomes and impacts is still limited. This study analyses the results of an impact evaluation of 30 small-scale energy development projects to better understand whether and how the supply of sustainable energy services supports productive use activities and whether these activities have the expected positive impacts on local livelihoods. A contribution analysis is applied to systematically evaluate the impact pathways for the productive use of energy. The results show that access to sustainable energy does not automatically result in productive activities and that energy is only one of the input factors required to foster socio-economic development. Furthermore, the results demonstrate that activities, materials and information to support the productive use of energy - such as training, equipment or market research - need to be an integrated part of the energy project itself to allow for productive activities to develop on a wider scale.

Description: The Port of Rotterdam is one of the pioneers in the reduction of greenhouse gas emissions. It is the largest port in Europe and extends over 40 kilometres to the North Sea coast. Its ambitious goal: the port wants to reduce greenhouse gas emissions from its industrial cluster as well as from freight traffic to a large extent. For the study "Deep Decarbonisation Pathways for Transport and Logistics Related to the Port of Rotterdam" the Wuppertal Institute analysed available options for the maritime as well was hinterland transports on behalf of the Rotterdam Port Authority. The 2050 scenarios by the Wuppertal Institute show that decarbonisation will significantly change both, volume and structure of the transported goods - which add to the on-going trend from bulk to container transport. This will have considerable structural effects on port operations and in particular on hinterland traffic. A comprehensive decarbonisation (〉95 per cent) will require significant efficiency improvements through operational and technical measures and the switch to non-fossil fuels, as well as a strong shift of container transport from road transport to rail and inland navigation. For maritime shipping to and from Rotterdam two feasible pathways towards full decarbonisation by 2050 are presented. Both include a stepwise shift towards renewable electricity based energy carriers for ships (liquids and gaseous for long distances and hydrogen and electricity for shorter distances). Finally the report derives a set of recommendations for the Port Authority as well as the Dutch, German and European policymakers to support the transition towards a drastic reduction of greenhouse gase (GHG) emissions from in the transport sector and for using this as a strategy for a sustainable economic development.

Description: Contemporary combined heat and power (CHP) systems are often based on fossil fuels, such as natural gas or heating oil. Thereby, small-scale cogeneration systems are intended to replace or complement traditional heating equipment in residential buildings. In addition to space heating or domestic hot water supply, electricity is generated for the own consumption of the building or to be sold to the electric power grid. The adaptation of CHP-systems to renewable energy sources, such as solid biomass applications is challenging, because of feedstock composition and heat integration. Nevertheless, in particular smallscale CHP technologies based on biomass gasification and solid oxide fuel cells (SOFCs) offer significant potentials, also regarding important co-benefits, such as security of energy supply as well as emission reductions in terms of greenhouse gases or air pollutants. Besides emission or air quality regulations, the development of CHP technologies for clean on-site small-scale power generation is also strongly incentivised by energy efficiency policies for residential appliances, such as e.g. Ecodesign and Energy Labelling in the European Union (EU). Furthermore, solid residual biomass as renewable local energy source is best suited for decentralised operations such as micro-grids, also to reduce long-haul fuel transports. By this means such distributed energy resource technology can become an essential part of a forward-looking strategy for net zero energy or even smart plus energy buildings. In this context, this paper presents preliminary impact assessment results and most recent environmental considerations from the EU Horizon 2020 project "FlexiFuel-SOFC" (Grant Agreement no. 641229), which aims at the development of a novel CHP system, consisting of a fuel flexible smallscale fixed-bed updraft gasifier technology, a compact gas cleaning concept and an SOFC for electricity generation. Besides sole system efficiencies, in particular resource and emission aspects of solid fuel combustion and net electricity effects need to be considered. The latter means that vastly less emission intensive gasifier-fuel cell CHP technologies cause significant less fuel related emissions than traditional heating systems, an effect which is further strengthened by avoided emissions from more emission intensive traditional grid electricity generation. As promising result, operation "net" emissions of such on-site generation installations may be virtually zero or even negative. Additionally, this paper scopes central regulatory instruments for small-scale CHP systems in the EU to discuss ways to improve the framework for system deployment.

Description: In this paper three approaches on transitions pathways are combined to study the role of agricultural nature conservation in the Dutch land use domain for achieving internationally agreed climate and biodiversity targets. The three perspectives used are the Multilevel Perspective (MLP), Initiative Based Learning (IBL) and Integrated Assessment Modelling (IAM). The analysis provides insights in how the combination of different research approaches can lead to more comprehensive policy advice on how agricultural nature conservation could help to achieve internationally agreed sustainability goals related to climate change and biodiversity. IAM shows under which conditions agricultural nature conservation could be consistent with European and global long-term goals regarding food security, biodiversity and climate. MLP provides insight into the extent in which agricultural nature conservation has affected or changed the existing nature and agricultural regimes. IBL, finally, reveals the challenges of encouraging agricultural nature conservation with policy measures. Our analysis shows that a combined perspective provides a deeper understanding of the underlying processes, reasons and motives of agricultural nature conservation, leading to more comprehensive policy recommendations.

Description: Urban areas, being responsible for large shares of global greenhouse gas emissions, are important arenas for achieving global decarbonisation. However, the systemic challenge of decarbonisation requires deep structural changes - transitions - that take place across multiple scales and along entire value chains. We argue in this article that understanding the role of urban areas for global decarbonisation therefore requires consideration of their context and analysis of urban areas' contributions to transitions that extend past the individual urban area. We develop an analytical framework that proposes three principal ways urban areas contribute to low-carbon transitions and ten competences that regional and local governance actors have to support them. We apply this framework to the Cologne metropolitan area in Germany to demonstrate the ability of our framework to relate urban-scale activities to more encompassing low-carbon transitions. The paper concludes with future research possibilities.

Description: This study is an exploratory analysis to provide a prioritisation and indication of extensiveness of review activities related to measures that currently exist for eight product groups: Domestic Washing Machines, Domestic Dishwashers, Domestic Washer-Driers, Domestic Cold Appliances, Lighting products (non-directional, tertiary and "special purpose"), Set-top Boxes. For water pumps only a review of tolerances was required. The analysis focused on possible energy savings as basis for prioritisation, but - following the request of the European Commission made during the kick-off meeting - also considers resource efficiency aspects insofar feasible within the constraints of the study. The conclusion of this exploratory study is that for all product groups considered (except pumps) a revision of existing regulations (or introduction of new regulations) is the preferred policy option. The analysis shows that these product groups are expected to (continue to) meet eligibility criteria for the introduction of ecodesign and/or energy labelling measures, with simple set top boxes as sole exemption as its market and environmental significance is in rapid decline (sales are expected to be marginal by 2020).

Description: Renewable energy plays a key role in the sustainable pathway towards a low carbon future and, despite new supply capacities, the transformation of the energy system also requires the adoption of a method which allows for the integration of increasing amounts of renewable energy. This requires a transition to more flexible processes at an industrial level and demand side management (DSM) is one possible way of achieving this transition. Currently, increased shares of variable renewable energy can cause the electricity supply to become more volatile and result in changes to the electricity market. In order to develop a new dynamic equilibrium to balance supply and demand, sufficient flexibility in demand is required. As adequate storage systems are not available in the short to medium term, the potential for large electricity consumers to operate flexibly is an attractive, pragmatic and feasible option. Recent studies in Germany suggest that there is significant potential for DSM in so-called "energy-intensive industries". However, the figures (which fall in the approximate range of 1,250-2,750 MW positive and 400-1,300 MW negative shiftable load) should be interpreted with caution. The range of industrial processes considered are diverse and vary from plant to plant, with the result that it is difficult to provide accurate calculations of the accumulated potential for Germany or the EU as a whole. Based on extensive surveys and panel discussions with representatives from energy-intensive industries (aluminum, cement, chemicals, iron & steel, pulp & paper), which together account for approximately one third of the industrial electricity demand in Germany, our paper provides an overview of both the opportunities and the barriers faced by DSM. One of the key findings is the possible loss in energy efficiency due to DSM: in order to decrease or increase production depending on the stability needs of the electricity system, plants and processes may no longer operate at their optimum levels. The effects on downstream production must also be taken into account in order to gain a more complete understanding of the overall effects of industrial DSM.

Description: The production of commodities by energy-intensive industry is responsible for 1/3 of annual global greenhouse gas (GHG) emissions. The climate goal of the Paris Agreement, to hold the increase in the global average temperature to well below 2 °C above pre-industrial levels while pursuing efforts to limit the temperature increase to 1.5 °C, requires global GHG emissions reach net-zero and probably negative by 2055-2080. Given the average economic lifetime of industrial facilities is 20 years or more, this indicates all new investment must be net-zero emitting by 2035-2060 or be compensated by negative emissions to guarantee GHG-neutrality. We argue, based on a sample portfolio of emerging and near-commercial technologies for each sector (largely based on zero carbon electricity & heat sources, biomass and carbon capture, and catalogued in an accompanying database), that reducing energy-intensive industrial GHG emissions to Paris Agreement compatible levels may not only be technically possible, but can be achieved with sufficient prioritization and policy effort. We then review policy options to drive innovation and investment in these technologies. From this we synthesize a preliminary integrated strategy for a managed transition with minimum stranded assets, unemployment, and social trauma that recognizes the competitive and globally traded nature of commodity production. The strategy includes: an initial policy commitment followed by a national and sectoral stakeholder driven pathway process to build commitment and identify opportunities based on local zero carbon resources; penetration of near-commercial technologies through increasing valuation of GHG material intensity through GHG pricing or flexible regulations with protection for competitiveness and against carbon leakage; research and demand support for the output of pilot plants, including some combination of guaranteed above-market prices that decline with output and an increasing requirement for low carbon inputs in government procurement; and finally, key supporting institutions.

Description: In this project, an overview and prioritization of relevant technologies of the German energy transition are presented in a consolidated form. Many of the relevant technologies have already been developed and deployed to the market. However, in various sectors like system integration or sector coupling, innovation needs remain, as well as in-depth research on further possibilities and potentials for cost degression and technology optimization for all technologies.

Description: Converting electricity into heat offers the opportunity to make of use large scales of renewable (surplus) energy in the long run in order to reduce shut-downs of renewable power plants and to substitute fossil fuels. Electrification seems to be also very promising for industrial heat applications, as it enables high process temperatures to be achieved in a tailor-made and efficient way and enables the utilisation of other energy sources like waste heat, geothermal or ambient heat (via heat pumps). This article analyses theoretical and technical electrification potentials of Steam Generation and Other Process Heat Generation in the following energy-intensive branches: iron & steel, non-ferrous metal, iron foundries, refineries, base chemicals, glass, cement clinker and paper industry in Germany. Literature research, expert interviews as well as own modelling were conducted to determine potentials and their implementation barriers. Based on these methods, market potential to electrify industrial steam generation was estimated. On the basis of two climate protection scenarios, the effects of both a monovalent and a hybrid industrial power-to-heat strategy were quantified with regard to greenhouse gas reduction and energy efficiency (primary energy saving). The pathway towards electrification will be reflected by criteria such as path dependency, dependency of infrastructure and system compatibility. Recommendations for research and development as well as policies are derived from the overall analysis. The article shows that electrification can be an important option to achieving high CO2-savings in the industrial heating sector in a long-term perspective. However, the scenario calculations show that electrification does not in itself guarantee reduction of greenhouse gases or savings of primary energy. To reach these goals, it is essential to further develop industrial heat pumps and to map electrification and further development of renewable energy (including infrastructure such as power networks and storage facilities) in a concerted strategy.

Description: The transformative research approach of Real-World Laboratories (RWL) has recently attracted attention in German sustainability science. Some definitions and understandings have been published, but guidelines and procedural quality criteria for establishing and running a RWL are still missing. To address this gap, this article has two aims. First, it aims to derive key components of RWLs from the current discourse on RWLs and similar, but more elaborated research approaches. Second, it aims to transfer these key components into a comprehensive research practice. This practice is illustrated by the RWL process in the project "Well-being Transformation Wuppertal" (WTW). Methodologically, the article builds on a review of RWL-related approaches for collaborative, intervention-oriented research. This includes transition management, transdisciplinary process models and action research. Based on this review, eight key components for RWLs are proposed. They position RWLs as a normatively framed approach that aims to contribute to local action for sustainable development and the empowerment of change agents. The approach uses transdisciplinary methods of knowledge integration and engages in cyclical real-world interventions within certain spatial and content-related boundaries. The components are transferred into a flowchart, detailing process steps, aims, responsibilities and overall principles for putting RWLs into practice. Thus, a hitherto missing tool for designing and running RWLs is provided. Then, the RWL in the district of Mirke, Wuppertal, is used as an empirical example to illustrate the application of the flowchart and related key components. Consecutive discussions centre on the different roles of researchers and practitioners in the research process, as well as the relevance of an underlying theory of change for effective interventions. Finally, critical reflection, application and amendment of the proposed flowchart are encouraged

Description: This study intends to provide a comprehensive overview of the water-energy nexus' relevance to the Iranian electricity sector, by illustrating key trends, analysing water-related challenges and identifying knowledge gaps. It summarises the results of a workshop, and a series of dialogues with Iranian energy and water experts, in which both the current situation and future water-related risks and impacts on the Iranian power sector were discussed. Based on those results, it highlights research needs and further options for scientific collaboration.

Description: The growing demand for timber, in particular for renewable energy, increases pressures on global forests and requires a robust monitoring system to ensure sustainability. This article takes a first step toward more systemic monitoring by asking how the global use of forests by EU consumers can be accounted for. Specifically, this article builds on and develops the method of global land use accounting to account for the EU-27's consumption of primary timber between 2002 and 2011 in terms of both volume and forest area. It assesses international trade flows for around 100 commodities and converts them into a volume of primary raw timber based on conversion values. Results reveal that both imports and exports increased over the assessed time period, with primary EU-27 timber estimated to be around 1 m3/cap in 2011. Gaps, uncertainty and a lack of harmonization regarding especially trade data and conversion values are key challenges to further improving the robustness of the method and reliability of results. Future research may focus on improving the method to address in particular recycled and recovered flows as well as the question of whether area or volume is the most appropriate metric for further development of a forest footprint indicator.

Description: In this paper we highlight the importance of structural dimensions of real-world laboratories (RwLs). Giddens' structuration theory provides a promising framework to better understand the interlinked abstract and physical (infra-)structural features of RwLs. We argue that research on and in RwLs needs to be sensitive to the spatial, temporal, and thematic scope of structuration processes. A systematic conceptualization of these dimensions remains an important task for future research. In order to arrive at such a more in-depth understanding and possibly an improvement in the transferability of knowledge created in RwLs, the idea proposed by the WBGU should be taken up: building RwLs for the long term and focusing more explicitly on their structural dimensions. First steps have been taken in the German city of Wuppertal where a RwL infrastructure has been built up over the course of various projects including a broad variety of resources, actors, and topics in the broader search and learning process for sustainable transitioning.
