The Sustainable Development Goals (SDGs) adopted by the United Nations provide normative orientation for many national and regional governments as well as actors from industry and other parts of the civil society. There is a growing consensus that the corresponding transformation processes needed – e.g., in the field of production and consumption patterns (SDG 12) – have to be fostered by a corresponding institutional framework. Properly designed experiments that generate a learning system for all actors involved may be an important building block. Based on an interdisciplinary approach, we provide an overview of the various terminologies for experimentation currently discussed in the social sciences, derive common criteria for a broader approach to the concept of “regulatory experimentation” in reflexive governance structures and present a novel conceptual framework for analysing empirical studies of regulatory experiments.

We present results of two model based scenario analysis focussing on the future German power sector which is characterized by a rising share of renewable energies and an associated higher demand for flexibility. Case study 1 is based on a general comparison between a decentrally and a centrally orientated electricity system. The research question of case study 2 is whether flexibility should be centrally balanced by a national market-based dispatch or dispatched in a decentralized manner within regional balancing areas. The combined results of these two case studies offer the possibility to show the differences between a decentralized and a centralized electricity system regarding the dispatch of generation, storage and flexibility options as well as resulting effects on variable costs, CO2 emissions, grid usage and RE integration. Decentralization as control strategy leads to higher variable generation costs due to more expensive generation and less efficient flexibility options that come into the market, while the majority of demand and supply still needs a transmission grid for balancing.

This article compares the drivers and barriers of two sustainability transformations in Germany: the energy transformation (“Energiewende”) andt he attempted transformation towards organic agriculture which has, so far, been less successful. It is based on two case studies rooted in transformation research. While there is rapidly growing literature on energy, there are far fewer analyses of agricultural transformations. Moreover, single case studies dominate. The cross-case comparison presented in this article is a step towards filling this gap. Particularly in their initial stages, the two transformation processes shared similarities: both systems had been coming under pressure due to environmental crises, grassroots movements and niche developments of sustainable alternatives. However, changes to the regulatory system framework made investments in renewable energy more attractive than in organic agriculture, where the profitability of the transformation is still reduced by significant subsidies for conventional agriculture. Moreover, the energy transformation has benefitted from technological improvements and falling costs, an early coalition of supporters, including business actors, and more recently from abroader societal and political consensus. ©2019 D.

In order to achieve a high renewable share in the electricity system, a significant expansion of cross-border exchange capacities is planned. Historically, the actual expansion of interconnector capacities has significantly lagged behind the planned expansion. This study examines the impact that such continued delays would have when compared to a strong interconnector expansion in an ambitious energy transition scenario. For this purpose, scenarios for the years 2030, 2040, and 2050 are examined using the electricity market model PowerFlex EU. The analysis reveals that both CO2 emissions and variable costs of electricity generation increase if interconnector expansion is delayed. This effect is most significant in the scenario year 2050, where lower connectivity leads roughly to a doubling of both CO2 emissions and variable costs of electricity generation. This increase results from a lower level of European electricity trading, a curtailment of electricity from a renewable energy source (RES-E), and a corresponding higher level of conventional electricity generation. Most notably, in Southern and Central Europe, less interconnection leads to higher use of natural gas power plants since less renewable electricity from Northern Europe can be integrated into the European grid.

In der Debatte um Klimaschutz und Förderung erneuerbarer Energien wird eine verstärkte stoffliche und thermische Verwendung von Holz als vermeintlich klimaneutraler Baustoff und Energieträger häufig pauschal als sinnvoll propagiert. Die Umsetzung dieses Narrativs führt zu intensiverer Nutzung der Wälder sowie zum weiteren Anstieg des globalen Rohholzaufkommens bei gleichzeitiger Verminderung der Holzvorräte und trägt auch zum Schwund der letzten europäischen Urwälder bei. Der vorliegende zweite Teil eines literaturbasierten Diskussionsbeitrags zu Urwäldern, Naturwäldern und Wirtschaftswäldern im Kontext des Biodiversitäts- und des Klimaschutzes analysiert die Entwicklung der Holzvorräte und Holzverwendung in Deutschland und beleuchtet die CO2-Senkenleistung von Holz für die vorherrschenden Nutzungspfade. Dieser Komplex hat wichtige Rückkopplungen zu Anliegen des Biodiversitätsschutzes. Kritisch betrachtet werden die Klimarelevanz von Holz als Substitut für andere Ressourcen und die vermeintliche CO2-Neutralität von Holz als Energiequelle. Die klimapolitischen Ziele der EU und Deutschlands und deren instrumentelle Umsetzung überschätzen die Leistungsfähigkeit von Wäldern als CO2-Senke und die Lieferfähigkeit für die Ressource Holz. Dies gilt besonders in Anbetracht der Folgen des Klimawandels. Die Forderung an die Politik ist der Verzicht auf Holzeinschlag in Ur- und Naturwäldern und die Einführung entsprechender normativer Vorgaben sowie Kriterien, um die Stammholznutzung für energetische Zwecke einzuschränken. Dies gilt speziell für Importe von Pellets und Hackschnitzeln zur Verstromung in Großkraftwerken. Eine thermische Nutzung von Holz und kurzlebigen Holzprodukten führt gegenüber der fossilen Referenz meist nur zu geringen bis keinen Reduktionen der Treibhausgasemissionen. Stofflich nicht weiter verwertbares Holz, Restholz oder Sägenebenprodukte sollten thermisch und dann möglichst ortsnah in effizienten Anlagen eingesetzt werden. Holz, das in Form von lebenden Bäumen oder Totholz im Wald verbleibt, kann im Vergleich zur energetischen und ineffizienten stofflichen Verwertung einen mindestens ebenso hohen, oft sogar größeren Beitrag zum Klimaschutz leisten. Nicht maximaler Ertrag, sondern Walderhalt mit möglichst resistenten und resilienten Beständen muss das vorrangige Ziel der Forst- und Holzwirtschaft sein.

In order to calculate the financial return of energy efficiency measures, a cost–benefit analysis (CBA) is a proven tool for investors. Generally, however, most CBAs for investors have a narrow focus, which is — simply speaking — on investment costs compared with energy cost savings over the life span of the investment. This only provides part of the full picture. Ideally, a comprehensive or extended CBA would take additional benefits as well as additional costs into account. The objective of this paper is to reflect upon integrating into a CBA two important cost components: transaction costs and energy efficiency services — and how they interact. Even though this concept has not been carried out to the knowledge of the authors, we even go a step further to try to apply this idea. In so doing, we carried out a meta-analysis on relevant literature and existing data and interviewed a limited number of energy experts with comprehensive experience in carrying out energy services. Even though data is hardly available, we succeeded in constructing three real-world cases and applied an extended CBA making use of information gathered on transaction costs and energy services costs. We were able to show that, despite these additional cost components, the energy efficiency measures are economically viable. Quantitative data was not available on how energy services reduce transaction costs; more information on this aspect could render our results even more positive. Even though empirical and conceptual research must intensify efforts to design an even more comprehensive CBA, these first-of-its-kind findings can counterargue those that believe energy efficiency is not worth it (in monetary terms) due to transaction costs or energy services costs. In fact, this is good news for energy efficiency and for those that seek to make use of our findings to argue in favor of taking up energy efficiency investments in businesses

The development of European power markets is highly influenced by integrated electricity and heat systems. Therefore, decarbonization policies for the electricity and heat sectors, as well as numerical models that are used to guide such policies, should consider cross-sectoral interdependencies and need evaluation. Many model-based policy assessments evaluate potential benefits of combined heat and power. However, the extent of benefits, such as emissions reductions, found in existing studies is subject to considerable variations. While scenarios and model inputs may partly explain such variations, differences in results may also be related to the model formulation itself. Against this background, this study is the first to compare electricity market models in the context of potential benefits of integrated electricity and heat systems in decarbonization. Five large-scale market models covering electricity and heat supply were utilized to study the interactions between a rather simple coal replacement scenario and a more ambitious policy that supports decarbonization through power-to-heat. With a focus on flexibility provision, emissions reduction, and economic efficiency, although the models agree on the qualitative effects, there are considerable quantitative differences. For example, the estimated reductions in overall CO2 emissions range between 0.2 and 9.0 MtCO2/a for a coal replacement scenario and between 0.2 and 25.0 MtCO2/a for a power-to-heat scenario. Model differences can be attributed mainly to the level of detail of combined heat and power modeling and the endogeneity of generation investments. Based on a detailed comparison of the modeling results, implications for modeling choices and political decisions are discussed.

: The Open Energy Ontology (OEO) is being developed as a domain ontology for energy system modelling. To increase its usability and react to user requirements, we introduce a post-coordination extension to OEO, the Open Energy Ontology Extended (OEOX). We create OEOX as an ontology for specific energy-related terms with a high complexity that go beyond the level of detail of the standard OEO class hierarchy. It allows for a dynamic ontology composition, enabling precise and tailored annotations for energy system data sets, requiring only minimal manual intervention or curation. In this paper, we describe the user-driven motivation for this ontology extension (Section 2). We illustrate the methodology and early-state practical implementation on behalf of post-composition patterns (Section 3). The ontological annotation of datasets in real-world applications and the usage of OEOX is described in Section 4, complemented by conclusions and summary in Section 5.

Given the challenges of future land use policies addressing sustainable natural resources management and socioeconomic aspects, the inter- and transdisciplinary GLOBALANDS (Global Land Use and Sustainability) project identified relevant international policy options, their synergies and possible implementation, and initiated and supported respective processes. GLOBALANDS identified also “windows of opportunity” to strengthen sustainable land use through international policies based on an extensive screening of the most important international policies – both governmental and non-governmental approaches – with relevant impacts on land use. Key processes which could strengthen global governance towards sustainable land use are:The proposed UN Sustainable Development Goals (SDGs) in which land is covered partially. Mainstreaming of sustainable land use in existing UN and international governance systems such as UN conventions to allow for more coherence Better safeguarding of sustainable land use in project-level financing of bi- and multilateral devel-opment agencies and bodies. The private sector can play an increasing role in the governance of sustainable land use, but this may require e.g., a certification system. GLOBALANDS developed a new (complementary) approach for land-related indicators which integrates environmental and social aspects through the formulation of sustainable land use practices for different actors, and regions. The application of such indicators is possible within the process of regionally or nationally implementing the SDGs.A final outcome of the GLOBALANDS project are policy recommendation for Germany policy to foster sustainable land use in the international governance system. Also, key open (research) questions were identified.

Nuclear cultural heritage (NCH) is a relatively new approach. It was introduced by Rindzevičiūtė (2019) and is being discussed internationally with reference to its contribution to knowledge preservation of nuclear objects and practices as well as safety aspects, especially in the context of nuclear waste governance. The latter includes knowledge transfer to future generations in the sense that knowledge of nuclear objects and practices might be further developed and could be applied as well in future. This is particularly relevant as nuclear technology is hazardous to the living environment and endures for very long periods of time. The great impacts on landscapes and the living environment are demonstrated by experiences with nuclear accidents, nuclear weapon tests, the storage and disposal of nuclear wastes, and uranium mining. One reason for the upcoming interest in NCH is the decommissioning of nuclear power plants and siting and construction of nuclear waste repositories. With this article, we aim to pr
