Die global gesehen größte Gesundheitsbedrohung des 21. Jahrhunderts ist der Klimawandel. Krankenhäuser müssen sich zwangsläufig vermehrt mit den Folgen des Klimawandels auseinandersetzen, wenn neue Krankheitserreger aus fernen Ländern auftreten oder wenn ältere Menschen, chronisch Kranke, Kinder oder anderweitig besonders betroffene Menschen an heißen Tagen mit bislang unerreichten Hitzerekorden dehydrieren mit der Folge von Herzkreislaufproblemen. Eine Untersuchung des Robert Koch-Instituts kommt zu dem Ergebnis, dass allein in den drei Sommern zwischen 2018 und 2020 in Deutschland über 19.000 Menschen aufgrund der Hitze gestorben sind.
Der Gesundheitssektor trägt aber auch wesentlich zur Klimakrise bei, indem er selbst für einen erheblichen Teil der klimaschädlichen Emissionen verantwortlich ist. Dieser Wuppertal Report zeigt einen Weg, wie Krankenhäuser perspektivisch Teil der Lösung der derzeit größten Transformationsherausforderung werden können. Dabei sind Krankenhäuser ein Mikrokosmos der Gesellschaft. In ihnen spiegelt sich förmlich alles, was das Leben einer Gesellschaft hinsichtlich der Herausforderung des Klimaschutzes ausmacht: Strom- und Wärmeversorgung, Mobilität, Ernährung, Ressourcenverbrauch und Abfall. Der vorliegende Wuppertal Report macht deutlich, dass Krankenhäuser als Reallabore des bevorstehenden Transformationsprozesses, hin zu einer klimagerechten und ressourcenleichten Gesellschaft verstanden werden können.
Das für die Krankenhausgesellschaft Nordrhein-Westfalen e. V. (KGNW) entwickelte Zielbild Klimaneutrales Krankenhaus gibt Krankenhäusern umsetzungsorientierte Hinweise darauf, wie sie sich auf den Weg zur Klimaneutralität begeben können:
Es identifiziert klimaschutzrelevante Handlungsfelder im Betrieb.
Es verdeutlicht, wie die KGNW die Krankenhäuser in NRW auf ihrem Weg in Richtung Klimaneutralität unterstützen kann.
Es motiviert, Klimaschutz als wichtiges Unternehmensziel aktiv anzugehen.
Eine Analyse der deutschen Energie- und Klimapolitik hat ergeben:
Nur im Maßnahmenfeld "Ausbau der Erneuerbaren Energien im Strombereich" wird voraussichtlich das Ziel ereicht. Dagegen wird in allen anderen Maßnahmenfeldern das Ziel verfehlt oder es bestehen Wirkungsdefizite der eingesetzten Politikinstrumente. Das betrifft insbesondere die Energieeffizienz auf der Nachfrageseite, aber auch die Kraft-Wärme-Kopplung und Erneuerbare Energien-Wärme. Für die Maßnahmenfelder "Fluorierte Treibhausgase", "Industrieprozesse" und "Landwirtschaft" müssen überhaupt erst verbindliche Reduktionsziele festgelegt und Politikinstrumente eingeführt werden.
What role do transaction costs play in energy efficiency improvements and how can they be reduced?
(2019)
Ex-ante policy evaluation requires a detailed understanding of how the subjects addressed by the policy react to its implementation. In the context of energy efficiency, policy measures typically aim at influencing investment decisions towards more efficient options.
As has been discussed widely in the context of the "energy efficiency gap", investments in energy efficiency improvements are frequently not conducted even though they seem cost-effective from a simple cost-benefit perspective, where transaction costs have been identified as one important barrier.
While transaction costs have been discussed widely from a conceptional perspective, empirical studies quantifying transaction costs and measures to reduce them are rare. This paper presents approaches, results and insights from a recently completed research project funded by the German Federal Energy Efficiency Center (BfEE), addressing transaction costs in various energy efficiency measures and the role of energy efficiency services to overcome the barrier.
We analyse a set of 11 energy efficiency investments covering private households, public institutions and the industry sector. We gather data on direct investment costs and energy cost savings and provide a detailed analysis of the various barriers and transaction costs associated with the implementation. We then analyse the costs of existing energy efficiency services using data provided by the BfEE. We compare the different cost elements and analyze the potential of energy efficiency services to reduce transaction costs.
We find that the role of transaction costs differs substantially between households, public institutions and companies and that the impact of energy efficiency services on transaction costs needs to be evaluated using different methodological approaches. We conclude that while data availability on disaggregated transaction costs is a major challenge, energy services can reduce transaction costs considerably.
What makes a good policy? : Guidance for assessing and implementing energy efficiency policies
(2013)
Which factors are crucial to successfully design and implement a "good practice" policy to increase the energy efficiency of buildings and appliances? This is one of the main challenges for the new web platform bigee.net that provides guidance on good practice policies.
In this paper we examine the question what "good practice" is by presenting a multi-criteria assessment scheme to analyse different policies worldwide.
The assessment scheme contains a set of criteria addressing key factors leading to the success of a policy as well as its outcomes: a good policy addresses all market players and barriers, avoids lost opportunities and lock-in effects, has ambitious and regularly updated energy efficiency levels, and spill-over effects. Other criteria are high energy savings and the calculated cost-effectiveness.
The assessment scheme provides a standardised data collection approach, which paves the way for both qualitative and quantitative evaluation. Furthermore, it can help policy-makers to transfer a successful policy.
The development of the scheme is based on a literature review of worldwide implemented policies and measures that promote energy-efficiency of buildings and appliances. Criteria were operationalized, including a ranking between 0 and 10. The ranking is a decisive factor whether the policy qualifies as good practice. To demonstrate the practicability of this scheme, the paper analyses a good practice example according to the assessment scheme: Energy-Efficient Refurbishment and Energy Efficient Construction programmes of the German public bank KfW.
Vor dem Hintergrund der europäischen Klimaschutzziele bis 2050 und der damit erforderlichen Dekarbonisierung der Wirtschaft werden in dem Vorhaben die Weiterentwicklungsoptionen der europäischen Energieeffizienzpolitiken untersucht. Es werden die Sektoren private Haushalte, Verkehr und Industrie betrachtet sowie der förderliche Rahmen, d. h. auch sektorübergreifende Instrumente. In den vorgeschlagenen Politikpaketen soll sich die Vielfalt der Instrumententypen abbilden. Neben Best-Practice-Beispielen liegen Länderstudien für drei große Volkswirtschaften der EU vor (Deutschland, Frankreich, Italien) und mit Polen auch eine Länderstudie für einen Mitgliedstaat aus dem mittelosteuropäischen Raum.
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 Digital Product Passport (DPP) is a concept of a policy instrument particularly pushed by policy circles to contribute to a circular economy. The preliminary design of the DPP is supposed to have product-related information compiled mainly by manufactures and, thus, to provide the basis for more circular products. Given the lack of scientific debate on the DPP, this study seeks to work out design options of the DPP and how these options might benefit stakeholders in a product's value chain. In so doing, we introduce the concept of the DPP and, then, describe the existing regime of regulated and voluntary product information tools focusing on the role of stakeholders. These initial results are reflected in an actor-centered analysis on potential advantages gained through the DPP. Data is generated through desk research and a stakeholder workshop. In particular, by having explored the role the DPP for different actors, we find substantial demand for further research on a variety of issues, for instance, on how to reduce red tape and increase incentives for manufacturers to deliver certain information and on how or through what data collection tool (e.g., database) relevant data can be compiled and how such data is provided to which stakeholder group. We call upon other researchers to close the research gaps explored in this paper also to provide better policy direction on the DPP.
The South African government started the development of a basic energy efficiency policy framework in 2005, including a voluntary label for refrigerators. This initial label was the intended precursor to a mandatory standards and labelling (S&L) programme, but the impacts achieved were only very limited. Based on this first experience, the South African Bureau of Standards (SABS) formed in 2008 a working group for the development of the new and more specific South African National Standard SANS 941. This standard identifies energy efficiency requirements, labelling and measurement methods as well as the maximum allowable standby power for a set of appliances as reliable basis for introducing a mandatory regulation. Nevertheless, due to many existing barriers, such as lack of funding and low priority assigned to the initiative, a very long period passed by between the S&L planning and final policy implementation. Finally, in November 2014, the South African government published mandatory performance standards coming into force in 2015/2016 for a first set of appliances consisting of refrigerators, washing machines, dryers, dishwashers, electric water heaters, ovens, A/C and heat pumps. To analyse the effectiveness of the new S&L programme and the potential influence of delays in the implementing process, the authors performed an immediate first-hand evaluation of the new policy.
As analytical reference base for available energy efficiency potentials, results from bottom-up scenario calculations will be presented exemplarily as case study for cold appliances covered by the S&L programme. A retrospective market study will show market trends before policy implementation and compare results with the new mandatory requirements. For the further policy analysis, a programme theory approach will be applied, in order to better understand why, how and under what conditions the policy works. Relationships with other energy efficiency policies and measures as well as positive or negative effects will be described. Furthermore, cause-impact relationships will be analysed to explain the functioning of the policy. Finally, success and failure factors will illustrate what needs to be done to achieve the desired energy efficiency targets. Henceforth, even though this study does not assess the direct transferability of the South African S&L programme to other regions, its findings could be relevant and useful for countries planning the implementation of similar policies.
In addition to the expansion of renewable energies, the efficient use of energy is crucial in order to ensure energy transition successful. The Federal Government of Germany has therefore set itself clear objectives with the National Energy Efficiency Action Plan (NAPE), which aims to reduce the primary energy consumption in Germany - compared to 2008 levels - by 20 per cent until 2020, and by 50 per cent until 2050. In addition, greenhouse gas emissions should fall by 40 per cent compared to 1990.
To reach this goal, the German Federal Ministry of Economic Affairs and Energy (BMWi) inter alia launched the "National Top Runner Initiative (NTRI)" in January 2016. It is an important component and concerns private homes, as well as industry, retail and services.
The NTRI is intended to bring energy efficient and high-quality appliances (so called Top Runners) onto the market more quickly, thus accelerate market replacement. For this purpose, motivation, knowledge and competence in product-related energy efficiency is to be strengthened and expanded along the whole value chain - from the appliance manufacturer to the retailer and the consumer. Manufacturers are pushed to develop more efficient products and consumers get valuable information about Top-Runner products and how they can benefit. In this context, retailers are especially relevant as they act as "gatekeeper" between manufacturers and consumers. They play a key role in advancing an energy efficient production and consumption. They do not only select the products but they also have a direct contact to consumers and influence the purchase decision. In this paper, special emphasis will be put on the role of retailers and the efforts of the National Top Runner Initiative will be illustrated. Barriers and incentives to motivate this target group will be elaborated.
