Energy sufficiency has recently gained increasing attention as a way to limit and reduce total energy consumption of households and overall. This paper presents both the partly new methods and the results of a comprehensive analysis of a micro- and meso-level energy sufficiency policy package to make electricity use in the home more sufficient and reduce at least the growth in per-capita dwelling size. The objective is to find out how policy can support households and their members, as individuals or as caregivers, but also manufacturers and local authorities in practicing energy sufficiency. This analysis needed an adapted and partly new set of methods we developed. Energy sufficiency does not only face barriers like energy efficiency, but also potential restrictions for certain household members or characteristics, and sometimes, preconditions have to be met to make more energy-sufficient routines and practices possible. All of this was analysed in detail to derive recommendations for which policy instruments need to be combined to an effective policy package for energy sufficiency. Energy efficiency and energy sufficiency should not be seen as opposed to each other but work in the same direction - saving energy. Therefore, some energy sufficiency policy instruments may be the same as for energy efficiency, such as energy pricing policies. Some may simply adapt technology-specific energy efficiency policy instruments. Examples include progressive appliance efficiency standards, standards based on absolute consumption, or providing energy advice. However, sufficiency may also require new policy approaches. They may range from promotion of completely different services for food and clothes cleaning, to instruments for limiting average dwelling floor area per person, or to a cap-and-trade system for the total electricity sales of a supplier to its customers, instead of an energy efficiency obligation.
Ahead of the Conference of Parties (COP) 24 where countries will first take stock of climate action post Paris, this paper assesses India's progress on its nationally determined contribution (NDC) targets and future energy plans. We find that, although India is well on track to meet its NDC pledges, these targets were extremely modest given previous context. Furthermore, there is considerable uncertainty around India's energy policy post 2030 and if current plans for energy futures materialise, the Paris Agreement's 2 degrees goal will be almost certainly unachievable. India's role in international climate politics has shifted from obstructionism to leadership particularly following the announcement of withdrawal by the United States from the Paris Agreement, but analysis reveals that India's "hard" actions on the domestic front are inconsistent with its "soft" actions in the international climate policy arena. Going forward, India is likely to face increasing calls for stronger mitigation action and we suggest that this gap can be bridged by strengthening the links between India's foreign policy ambitions, international climate commitments, and domestic energy realities.
Digital platforms may yield a host of advantages in putting circular economy into effect. This paper analyses the related chances and discusses requirements of digital platforms for the realization of a circular economy. It specifically points to potential solutions offered by digital platforms for existing barriers. From there it identifies issues that need specific attendance to create economically and ecologically functional platforms. Three economically relevant perspectives are discussed for this: a management perspective, a legislative perspective and a social/systems perspective.
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.
The potential of mixed-mode office buildings with varying design and control parameters is examined by using an uncertainty analysis in the three climate zones of India. The analysis is in terms of cooling energy consumption, thermal comfort conditions, and natural ventilation hours. Furthermore, influential parameters are identified using sensitivity analysis. In this study, opening the windows enables natural ventilation. Night-time ventilation through the windows is not enabled because these are mostly closed at night. A maximum natural ventilation of 10% of the total building occupancy hours are observed in warm and humid, and hot and dry climates; however, they are slightly higher in the composite climate. A further increase in the number of natural ventilation hours leads to an increase in the occupancy hours outside the Indian Model for Adaptive Comfort model for mixed-mode buildings with at least 90% of occupants are satisfied. There are no occupancy hours outside of 80% of occupants are satisfied. The choice of thermal comfort band is crucial for determining the potential of mixed-mode buildings. The cooling setpoint temperature, building size, window solar heat gain coefficient, and surface properties of exterior surfaces are identified as the more influential parameters than the thermophysical properties of building envelope constructions. Although the building envelope which is in compliance with the Energy Efficient Building Code of India increases energy efficiency during air-conditioning periods, whether it reduces natural ventilation hours, because of overheating during such period remains to be determined.
A policy mix for resource efficiency in the EU : key instruments, challenges and research needs
(2019)
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.
With the introduction of the Roadmap to a Resource Efficient Europe (2011) and the more recent commitment of The Action Plan towards the Circular Economy (2015), the European Commission (EC) has expressed its fundamental interest to substantially improve the resource efficiency of the European economy and enable the transition towards the Circular Economy (CE). This policy push has meanwhile been complemented by some quite ambitious national programmes for RE and CE and institutional advances but it is not yet bound to targets or mandatory reporting.
Against this background, the objective of this paper is to give a comprehensive overview of the current policy frameworks at EU and a selection of MSs and provide insights into the elements shaping policy processes. The analytical framework relies on three essential interconnected components: the policy framework, the economic incentive system and economic side policies which are relevant in the context of RE and CE and actor constellations. The paper does this looking at the interface between EU-MSs. The analysis is based on different empirical surveys in which the policy development is observed and discussed (EEA 2011, 2016a, 2016b, EIO 2013, 2014, 2016) and a comprehensive review of legislative and policy frameworks at the EU and selected MSs, undertaken as part of the project POLFREE (Policy option for a Resource-Efficient Economy) (Domenech et al., 2014, Bahn-Walkowiak et al., 2014). The analysis reveals that policy frameworks for RE/CE are complex and fragmented as competing goals and visions reduce effectiveness of measures. The paper makes recommendations as to how EU and MS policies could improve RE in a coordinated way, but recognizes that achieving such coordination will be challenging in the current political context.
Sustainable Development Goals and the Paris Agreement stand as milestone diplomatic achievements. However, immense discrepancies between political commitments and governmental action remain. Combined national climate commitments fall far short of the Paris Agreement's 1.5/2°C targets. Similar political ambition gaps persist across various areas of sustainable development. Many therefore argue that actions by nonstate actors, such as businesses and investors, cities and regions, and nongovernmental organizations (NGOs), are crucial. These voices have resonated across the United Nations (UN) system, leading to growing recognition, promotion, and mobilization of such actions in ever greater numbers. This article investigates optimistic arguments about nonstate engagement, namely: (a) "the more the better"; (b) "everybody wins"; (c) "everyone does their part"; and (d) "more brings more." However, these optimistic arguments may not be matched in practice due to governance risks. The current emphasis on quantifiable impacts may lead to the under-appreciation of variegated social, economic, and environmental impacts. Claims that everybody stands to benefit may easily be contradicted by outcomes that are not in line with priorities and needs in developing countries. Despite the seeming depoliticization of the role of nonstate actors in implementation, actions may still lead to politically contentious outcomes. Finally, nonstate climate and sustainability actions may not be self-reinforcing but may heavily depend on supporting mechanisms. The article concludes with governance risk-reduction strategies that can be combined to maximize nonstate potential in sustainable and climate-resilient transformations.
Addressing food waste prevention is one target of the Sustainable Development Goals (SDGs) and a major task for the UN Environmental Programme and the European Commission. It is promising in terms of its environmental saving potential. However, it also leads to consumers being able to save money, which they then are likely to spend, thus again causing a negative environmental impact. This dimension of the so-called indirect rebound effect, which prevents the desired ecological benefits from being achieved, is investigated in this paper. By using a single-region environmentally extended input-output model from a production perspective, the indirect rebound effects from food waste prevention in Germany are analysed. Any political action needs to consider not only a differentiation in income class, but also alternative concepts such as the principles of sufficiency in order to achieve all ecological benefits and specifically the third target of SDG 12.
Der Eon/RWE-Deal : Marktbeherrschung und Shareholder Value-Politik mit behördlicher Zustimmung
(2019)
Am 17. September 2019 hat die EU-Wettbewerbs-Kommissarin Margrethe Vestager dem Stromkonzern Eon die Übernahme und Zerschlagung der RWE-Tochter Innogy unter leichten Auflagen erlaubt. Damit geht eine vollständige Geschäftsfeldaufteilung zwischen den beiden mächtigsten nationalen Energiekonzernen Eon und RWE einher. Während sich Eon auf die Bereiche Vertrieb und Verteilnetzbetrieb konzentrieren wird, übernimmt RWE die konventionellen Kraftwerke des bisherigen Konkurrenten sowie alle Anlagen der erneuerbaren Stromerzeugung. Auch alle vor rund zwei Jahren zunächst an Innogy abgegebenen Anlagen zur Stromerzeugung werden von RWE wieder zurückgeholt. Zudem erhält RWE eine 16,7-prozentige Beteiligung an Eon. Dazu gab das Bundeskartellamt (BKartA) bereits am 26.02.2019 bekannt, dass es diese Beteiligung für unbedenklich hält.
Die Freigabe der EU-Kommission vom September 2019 ist eine "Entscheidung von enormer Tragweite" die den "gesamten Sektor grundlegend verändern" wird. Denn durch diesen Mega-Deal entstehen im deutschen Energiesektor zwei monolithische Giganten mit bisher nie dagewesener Marktmacht.
Unter den Stichworten "Sektorenkopplung" und "Power-to-X" werden derzeit viele Möglichkeiten der direkten und indirekten Elektrifizierung großer Teile der Endenergienachfrage intensiv diskutiert. In diesem Zusammenhang hat die Diskussion um Wasserstoff als Endenergieträger sowie als Feedstock für die Herstellung von synthetischen Kraftstoffen und chemischen Grundstoffen zuletzt stark an Bedeutung gewonnen. Insbesondere der klimaneutrale Umbau der Grundstoffindustrien und hier vor allem der Grundstoffchemie und der Stahlindustrie würde bedeutende Mengen an grünem Wasserstoff benötigen, die räumlich stark auf die großen Industriekerne fokussiert wären. Ein zeitnaher Einstieg in die Schaffung entsprechender Erzeugungskapazitäten und Infrastrukturen könnte dazu führen, dass Wasserstoff - neben erneuerbaren Energien und Energieeffizienz - zum dritten Standbein der Energiewende avanciert.
Creating statistics for China's building energy consumption using an adapted energy balance sheet
(2019)
China's regular energy statistics does not include the building sector, and data on building energy demand is included in other types of energy consumption in the Energy Balance Sheet (EBS). Therefore data on building energy demand is not collected based on statistics, but rather calculated or estimated by various approaches in China. This study aims at developing and testing China's building energy statistics by applying an adapted EBS. The advantage of the adapted EBS is that statistical data is from the regular statistical system and no additional statistical efforts are needed. The research result shows that the adapted EBS can be included in China regular energy statistical system and can be standardized in a transparent way. Testing of the adapted EBS shows that China's building energy demand has shown an annual increase of 7.6% since 2001, and a lower contribution to the total energy demand as compared to the developed world. There is also a close link to lifestyle and living standard while industrial energy demand is mainly driven by economy and decoupling of building energy demand with increasing of building floor area, this is due to a considerable improvement of building energy efficiency. The adapted EBS creates a method for China conducting statistics of building energy consumption at the sector level in a uniform way and serves as the basis for any sound building energy efficiency policy decisions.
In vielen deutschen Städten sinken die verkehrsbedingten CO2-Emissionen kaum und vor allem die Belastungen durch Luftschadstoffe aus dem Straßenverkehr sind weiterhin sehr hoch. Deshalb beklagt die Deutsche Umwelthilfe inzwischen über 30 Städte in Deutschland, um durch Fahrverbote für Dieselfahrzeuge das Recht der Menschen auf saubere Atemluft durchzusetzen. Daher suchen die Kommunen zunehmend Wege, die verkehrsbedingten Emissionen zu senken. Dabei kommt kommunalen Flottenbetreibern eine besondere Rolle zu. Sie stehen besonders unter Handlungsdruck, weil durch ein Fahrverbot für Dieselfahrzeuge diese nur noch sehr eingeschränkt eingesetzt werden könnten.
Green Information Systems in general, and footprint calculators in particular, are promising feedback tools to assist people in adopting sustainable behaviour. Therefore, a Material Footprint model for use in an online footprint calculator was developed by identifying the most important predictors of the Material Footprint of the calculator's users. By means of statistical learning, the analysis revealed that 22 of the 95 predictors identified accounted for 74% of the variance in Material Footprints. Ten predictors out of the 95, mainly from the mobility domain, were capable of showing a prediction accuracy of 61%. The authors conclude that 22 predictors from the areas of mobility, housing and nutrition, as well as sociodemographic information, accurately predict a person's Material Footprint. The short and concise Material Footprint model may help developers and researchers to enhance their information systems with additional items while ensuring the data quality of such applications.
Footprint calculators are efficient tools to monitor the environmental impact of private consumption. We present the results of an analysis of data entered into an online Material Footprint calculator undertaken to identify the socioeconomic drivers of the Material Footprint in different areas of consumption, from housing to holidaymaking. We developed regression models to reveal (1) the impact of socioeconomic characteristics on Material Footprints of private households and (2) correlations between the components of Material Footprints for different arrays of consumption. Our results show that an increasing Material Footprint in one array of consumption comes with an increasing Material Footprint in all other arrays, with the exception of housing and holidaymaking. The socioeconomic characteristics of users have a significant impact on their Material Footprints. However, this impact varies by the array of consumption. Households only exhibit generally bigger Material Footprints as a result of higher incomes and larger dwellings. We conclude that indicators which strive to monitor resource efficiency should survey disaggregated data in order to classify the resource use to different population groups and arrays of consumption.
Reflecting trends in the academic landscape of sustainable energy using probabilistic topic modeling
(2019)
Background: Facing planetary boundaries, we need a sustainable energy system providing its life support function for society in the long-term within environmental limits. Since science plays an important role in decision-making, this study examines the thematic landscape of research on sustainable energy, which may contribute to a sustainability transformation. Understanding the structure of the research field allows for critical reflections and the identification of blind spots for advancing this field.
Methods: The study applies a text mining approach on 26533 Scopus-indexed abstracts published from 1990 to 2016 based on a latent Dirichlet allocation topic model. Models with up 1100 topics were created. Based on coherence scores and manual inspection, the model with 300 topics was selected. These statistical methods served for highlighting timely topic trends, differing thematic fields, and emerging communities in the topic network. The study critically reflects the quantitative results from a sustainability perspective.
Results: The study identifies a focus on establishing and optimizing the energy infrastructure towards 100% renewable energies through key modern technology areas: materials science, (biological) process engineering, and (digital) monitoring and control systems. Energy storage, photonic materials, nanomaterials, or biofuels belong to the topics with the strongest trends. The study identifies decreasing trends for general aspects regarding sustainable development and related economic, environmental, and political issues.
Conclusions: The discourse is latently adopting a technology-oriented paradigm focusing on renewable energy generation and is moving away from the multi-faceted concept of sustainability. The field has the potential to contribute to climate change mitigation by optimizing renewable energy systems. However, given the complexity of these systems, horizontal integration of the various valuable vertical research strands is required. Furthermore, the holistic ecological perspective considering the global scale that has originally motivated research on sustainable energy might be re-strengthened, e.g., by an integrated energy and materials perspective. Beyond considering the physical dimensions of energy systems, existing links from the currently technology-oriented discourse to the social sciences might be strengthened. For establishing sustainable energy systems, future research will not only have to target the technical energy infrastructure but put a stronger focus on issues perceivable from a holistic second-order perspective.
The current global momentum for carbon pricing has lately produced innovative hybrids: carbon taxes allowing the use of offsets from emission sources not targeted by the carbon tax for compliance with the tax load. This study aims at filling the knowledge gap in existing literature by exploring the potential impacts of domestic offset components in carbon taxes on mitigation of national emissions, including the country examples Colombia, Mexico and South Africa.
The findings indicate that the use of offsets in carbon taxes may significantly influence mitigation of national emissions both positively and negatively. On the one hand, this model may result in real emission reductions from offset projects and positive spillover effects of efforts to reduce emissions from emission sources covered by the carbon tax to other emission sources. Furthermore, the offsetting component can be used as a bargaining chip in political negotiations facilitating the introduction of mitigation policies and measures and/or strengthening their ambition level. On the other hand, it also entails serious risks: Offsetting could compromise the environmental integrity of the carbon tax through low-quality offsets. Furthermore, offsets reduce incentives to curb emissions in the emission sources covered by the carbon tax, potentially leading to carbon lock-in effects. Moreover, an offsetting component could provoke opposition to further climate policies and measures for emission sources generating offsets, as replacing the offsetting component with mandatory emission reduction policies would eliminate revenues from offset credits. General opposition of stakeholder groups to the introduction of offsets may even hinder the introduction of carbon pricing instruments and offsetting altogether.
The study identifies options that could be employed to increase potential positive effects of introducing an offset component to a carbon tax and mitigate related risks, pointing to the country examples included, where appropriate.
Diesen Technologien wird für das Energiesystem, bei einem zunehmenden Ausbau der fluktuierenden regenerativen Leitenergieträger Wind und Sonneneinstrahlung als zentrale Flexibilitätsoption sowie zur Dekarbonisierung der Industrie - Bereitstellung von Wasserstoff und Kohlenwasserstoffen -, eine Schlüsselrolle zukommen. Wie die bisherigen Erfahrungen mit anderen Energieinfrastrukturen, z. B. Freileitungen oder Windkraftanlagen, zeigen, stellt eine breite gesellschaftliche Akzeptanz einen wesentlichen Erfolgsfaktor für die großflächige Diffusion und Transformation dar. Entsprechend ist die gesellschaftliche Einbettung auch bei der Planung von PtX-Strategien frühzeitig zu beachten.
Theoretical advances suggest that international governance in general and the Paris Agreement in particular provide a strong signal guiding sociotechnical systems toward decarbonization. We assess this signal and its effects empirically, by examining the struggle of competing narratives as present in the communications of leading US fossil fuel industry associations and companies. The results are then discussed in the context of the national and international climate and energy policy debates in a study period from late 2014 until the announcement of withdrawal from the Paris Agreement in June 2017. We find that the Paris Agreement has institutionalized a narrative paradigm that is surprisingly resilient. While the election of Donald Trump and his climate and energy policy led to a narrative shift in the coal industry, the oil and gas industry remained conspicuously silent in its immediate response and maintained its narrative strategies despite its alignment with the Paris Agreement.
Many countries are increasingly investing in renewable energy technologies to meet growing energy demands and increase the security of their energy supply. This development is also evident in the Middle East and North Africa (MENA) region, where renewable energy targets and policies have evolved rapidly in recent years. There is a steady increase in both the number of planned and implemented solar photovoltaic (PV) but also of solar thermal projects in form of Concentrating Solar Power (CSP) plants. Many of these installations are designed as large utility-scale systems. Despite the fact that these types of large-scale projects can have significant effects on local communities and their livelihoods, the existing research into the social impacts of such large-scale renewable energy infrastructures at local level is limited. However, assessing and managing these impacts is becoming increasingly important to reduce risks to both the affected communities and to the project and businesses activities. In order to provide more robust evidence on the local effects, this research study reviews the social impacts of large-scale renewable energy infrastructure in the MENA region based on a case study of the NOORo I CSP plant in Ouarzazate, Morocco. Data collected during two empirical field studies, in combination with expert interviews and secondary data analysis, provides detailed evidence on the type and significance of livelihood impacts of the NOORo I CSP plant. The analysis results in a consolidated list of 30 impacts and their significance levels for different stakeholder groups including farmers, young people, women, community representatives and owners of small and medium enterprises. The results show that, overall, the infrastructure development was received positively. The review also indicates that factors identified as having effects on the sustainability of local livelihoods are mainly related to information management and benefit distribution, rather than physical or material aspects.
