An important share of Middle European countries’ energy consumption is used for space heating. The latter is determined by building energy efficiency, user practices, and floor space. Research and policy tend to focus on the first two factors and neglect the latter. In the German residential sector, per capita floor space has been increasing for decades, causing important rebound effects. Reducing per capita floor space by only 2 m2 could bring 6% savings in heat energy. Senior homeowners are a relevant target group. When grown-up children move out, they typically remain in the homes constructed for a family. 13% of all households in Germany belong to this group. Their average floor space is 70.6 m2 per capita, compared to the national average of 43.8 m2. These homes are often in need of modernization, and not very energy efficient or barrier-free. The paper presents first results of the transdisciplinary research project “LivingSpaces”, carried out in the district of Steinfurt in Western Germany. Its objective is to develop and assess policy instruments which support senior citizens in choosing housing alternatives that are both space-saving and suitable for their future needs – for example in terms of accessibility, energy efficiency, convenience, or community. Examples are moving to a smaller place, letting out parts of the home, or rebuilding the home so it can be shared with others. The paper will present results of a representative survey that systematically explores senior citizens’ attitudes towards various housing options. Furthermore, it will explain the communication approach that is at the heart of LivingSpaces and consists of several modules such as an awareness campaign, an innovative personal advice service “new housing in old age”, workshops, and setting up a support structure that helps with practical issues such as legal, financial or organizational questions.

The energy crisis following the Russian invasion of Ukraine has prompted affected countries to increase efforts to save energy. Despite substantial energy conservation observed across sectors, research has inadequately explored the reasons behind these savings. This study bridges this gap by analyzing the discourse on energy conservation during the crisis in Germany, using Twitter data. We analyse a set of 136,837 tweets from January 2022 until May 2023. The analysis consists of two approaches based on natural language processing (NLP): First, we conduct word counts within the days with high tweet activity related to energy saving to identify specific triggers. For a broader quantitative analysis, we then use text classification to categorize the data set into different aspects as well as different stances and investigate how these evolve during the crisis. Our results show a heightened focus on energy conservation in the Twitter debate during the crisis, reflected in an increase of the average monthly tweets

Die Diskussion um die Nutzung von Wäldern im Spannungsfeld von Holzproduktion, ihrem Beitrag zum Klimaschutz und der Verpflichtung zum Schutz der Biodiversität von Waldökosystemen wird mit Schärfe geführt. Es werden dabei auch Klimaschutzargumente bemüht, um Anliegen des Biodiversitätsschutzes zu diskreditieren. Manche der angeführten Argumente basieren auf einer fragwürdigen Datenbasis und -interpretation. In der Gemengelage geht es nicht nur um den Umgang mit Forderungen zu mehr Flächenstilllegungen von Wirtschaftswäldern und den Schutz von Naturwäldern in Deutschland, es droht auch der Verlust der letzten großflächigen europäischen temperaten Urwälder, die alle im Karpatenbogen liegen. Ursächliche Faktoren sind die intensive und zunehmende Holznutzung, ein unzureichender politischer Wille und ein zu geringes nationales und europäisches Engagement für den Schutz dieses Weltnaturerbes. Urwälder und Naturwälder sind in den EU-Mitgliedsstaaten auf weniger als 3 % der Gesamtwaldfläche erhalten geblieben; hunderttausende Hektar europäischer Urwälder gingen allein in den vergangenen zehn Jahren verloren. In diesem zweiteiligen Aufsatz diskutieren wir Argumente zu den Themenkomplexen (1) Biodiversität und Forstwirtschaft, (2) CO2-Speicher- und -Senkenleistung genutzter und ungenutzter Wälder und (3) Klimaschutzwirkung der energetischen Holznutzung vor dem Hintergrund aktueller klimapolitischer Entscheidungen der EU und der Bundesregierung. Der vorliegende erste Teil befasst sich mit dem Vorkommen von Ur- und Naturwäldern in Europa und widerlegt die These, diese könnten keinen wichtigen Beitrag zum Biodiversitätsschutz leisten. Außerdem wird der Beitrag von Urwäldern, Naturwäldern und Wirtschaftswäldern mit dem Klimaschutz vergleichend bewertet.

The 24th international climate conference in Katowice, Poland, in December 2018 was a major achievement in the multilateral response to climate change. More than 190 countries managed to agree on nearly all elements of a comprehensive rulebook that puts flesh on the bones of the 2015 Paris Agreement. The rules require, for the first time, that all countries provide detailed information on their climate change mitigation targets and regularly report on their progress in implementing and achieving them. However, one important chapter is still missing: rules for international carbon markets discussed under Article 6 of the Paris Agreement. Competing views on how to avoid “double counting”—counting the same emission reduction more than once to achieve climate mitigation targets—were a major roadblock to reaching consensus. Completing the missing chapter on Article 6 will be one of the key tasks when countries reconvene at the 25th international climate conference in Santiago, Chile, in December of this year. We highlight why resolving double counting is critical for achieving the goals of the Paris Agreement and identify essential ingredients for a robust outcome that ensures environmental effectiveness and facilitates cost-effective mitigation.

A variety of models have emerged in the field of energy system analysis to answer a wide range of research questions centred around a sustainable future for the energy sector. Even models designed to address similar issues often have a different focus or modelling approach. Thus, model experiments are a vital tool to provide an overview of the range of models and enable decision-makers to make meaningful model choices. Such comparisons are executed based on a harmonised data set to ensure a high degree of comparability. In the MODEX project cluster, six model experiments, including 40 energy system models, were conducted, and efforts were made to harmonise the input data within the individual comparison and beyond them in the consortium. The experiences and findings of the consortium on how data harmonisation could be performed are presented in this paper. In particular, the focus lies on data transparency to ensure a high degree of reproducibility. A key finding is that while model heterogeneity complicates harmonisation, an early focus on data research and scenario design promotes the creation of a common data set. The metadata collection can provide a significant advantage for the use of model experiment results by external scientists and the data acquisition process itself because of the predefined machine-readable and standardised format.

The Global Stocktake (GST) takes a central role within the architecture of the Paris Agreement, with many hoping that it will become a catalyst for increased mitigation ambition. This paper outlines four governance functions for an ideal GST: pacemaker, ensurer of accountability, driver of ambition and provider of guidance and signal. The GST can set the pace of progress by stimulating and synchronizing policy processes across governance levels. It can ensure accountability of Parties through transparency and public information sharing. Ambition can be enhanced through benchmarks for action and transformative learning. By reiterating and refining the long term visions, it can echo and amplify the guidance and signal provided by the Paris Agreement. The paper further outlines preconditions for the effective performance of these functions. Process-related conditions include: a public appraisal of inputs; a facilitative format that can develop specific recommendations; high-level endorsement to amplify the message and effectively inform national climate policy agendas; and an appropriate schedule, especially with respect to the transparency framework. Underlying information provided by Parties complemented with other (scientific) sources needs to enable benchmark setting for collective climate action, to allow for transparent assessments of the state of emissions and progress of a low-carbon transformation. The information also needs to be politically relevant and concrete enough to trigger enhancement of ambition. We conclude that meeting these conditions would enable an ideal GST and maximize its catalytic effect.

Energy sufficiency is one of the three energy sustainability strategies, next to energy efficiency and renewable energies. We analyse to what extent European governments follow this strategy, by conducting a systematic document analysis of all available European National Energy and Climate Plans (NECPs) and Long-Term Strategies (LTSs). We collect and categorise a total of 230 sufficiency-related policy measures, finding large differences between countries. We find most sufficiency policies in the transport sector, when classifying also modal shift policies to change the service quality of transport as sufficiency policies. Types of sufficiency policy instruments vary considerably from sector to sector, for instance the focus on financial incentives and fiscal instruments in the mobility sector, information in the building sector, and financial incentive/tax instruments in cross-sectoral application. Regulatory instruments currently play a minor role for sufficiency policy in the national energy and climate plans of EU member states. Similar to energy efficiency in recent decades, sufficiency still largely referred to as micro-level individual behaviour change or necessary exogenous trends that will need to take place. It is not treated yet as a genuine field of policy action to provide the necessary framework for enabling societal change. Published in: Energy Policy, Volume 157, October 2021, 112483

Germany’s third largest state, Baden Württemberg, was the first to mandate the installation of renewable heating technologies in 2008. Owners of a heating system need to employ a minimum share of renewable energy of 15% of the heat demand when the heating system is replaced. Instead of employing a renewable heating system, the building owner can also opt for efficiency measures, including insulation of the building. A part of the obligation can be fulfilled by carrying out an energy audit based on an individual building roadmap. For the first time, the effects of the Renewable Heating Act Baden-Württemberg have been evaluated in detail, based on statistical analyses of the available verifications, on market observations, interviews with 1000 clients, 150 heating installers, 250 chimney sweepers, 50 building companies, clients of energy audits and various stakeholder workshops and interviews, leading to a model calculation of estimated savings of the law. The paper will present the empirical findings and investigate the various mechanisms of the renewable and efficiency requirement, including direct and indirect effects, trigger effects, windfall effects and wait-and-see attitudes. Overall, the law provides positive impetus for additional installations of renewable energies, more energy efficiency and advice. This effect results from the sum of different effects: through the explicit requirements, it provides an additional direct incentive to expand renewable energies and substitute measures. Indirectly, the law strengthens the involvement with renewable energies both in the consultation process with heating engineers and planners/architects and in the purchase decision of customers. Additional energy consulting is also encouraged. However, the positive market figures compared to the federal trend are not completely causally attributable to the EWärmeG.The paper will conclude with a set of improvements of the Act itself and the surrounding policy landscape.

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.
