In diesem Gutachten wurde untersucht, welche Optionen zur Gestaltung eines marktbasierten haushaltsunabhängigen Verpflichtungsansatzes zur CO2-Minderung im deutschen Gebäudebestand bestehen. Die Analyse erfolgte technologieoffen und berücksichtigte neben Sanierungsmaßnahmen zur Steigerung der Energieeffizienz auch einen verstärkten Einsatz CO2-armer/erneuerbarer Energien. Das Verpflichtungssystem soll in der Lage sein, die bestehenden Treibhausgas (THG)-Minderungsziele im Gebäudebestand möglichst kostengünstig auf kurz- und langfristig sinnvolle Weise zu erreichen und sich gut in das bestehende Förderinstrumentarium integrieren lassen.
Kosten des Klimawandels

In the energy sector, few topics, if any, are more hyped than hydrogen. Countries develop hydrogen strategies to provide a perspective for hydrogen production and use in order to meet climate-neutrality goals. However, in this topical field the role of water is less accentuated. Hence, in this study, we seek to map the interrelations between the water and wastewater sector on the one hand and the hydrogen sector on the other hand, before reflecting upon our findings in a country case study. We chose the Hashemite Kingdom of Jordan because (i) hydrogen is politically discussed not least due to its high potentials for solar PV, and (ii) Jordan is water stressed - definitely a bad precondition for water-splitting electrolyzers. This research is based on a project called the German-Jordanian Water-Hydrogen-Dialogue (GJWHD), which started with comprehensive desk research mostly to map the intersectoral relations and to scope the situation in Jordan. Then, we carried out two expert workshops in Wuppertal, Germany, and Amman, Jordan, in order to further discuss the nexus by inviting a diverse set of stakeholders. The mapping exercise shows various options for hydrogen production and opportunities for planning hydrogen projects in water-scarce contexts such as Jordan.
Dieses Wuppertal Paper dient dazu, a) die mögliche Klimaschutzwirkung eines CO2-Preises zu analysieren, allein und im Gesamtpaket von Instrumenten zum Klimaschutz, b) die Möglichkeiten der Mittelverwendung zu analysieren und zu bewerten, c) dadurch den Dschungel der Argumente und Motivationen in den bestehenden Vorschlägen zu lichten und d) aus der Analyse ein Modell zu skizzieren, das den Anforderungen von Klimaschutz und sozialer Gerechtigkeit sowie Erhalt der Wettbewerbsfähigkeit am besten gerecht wird und damit der Bundesregierung als Anregung bei der Entscheidung über Einführung und Ausgestaltung eines CO2-Preises dienen kann.
In dem Papier werden diese Fragen anhand von neun Thesen mit einem abschließenden Fazit ergründet. Daraus wird deutlich:
Ein CO2-Preis kann sektorale Ziele und Instrumente nicht ersetzen. Seine volle Wirkung kann er nur entfalten, wenn er komplementär zu sektorspezifischen Klimaschutzinstrumenten eingeführt wird. Nur wenn für diese Instrumente ein guter Teil der Einnahmen aus der CO2-Steuer eingesetzt wird, sind die Klimaziele erreichbar. Die Ziele werden dadurch mit weitaus geringerem CO2-Preis bei gleichzeitig höheren Kostenentlastungen für Verbraucherinnen und Verbraucher, Unternehmen und sogar die öffentlichen Haushalte erreichbar, als wenn die Politik allein auf einen CO2-Preis setzen würde.
The energy system of Jordan is facing a rise in energy demand while at the same time having quite limited own conventional energy resources. Especially because of their high import dependency, Jordan is starting to change its energy system and puts a higher focus on renewable energy (like wind and solar) and energy efficiency.
In this short paper the authors discuss the transformation of energy companies in Germany and highlight the possibilities of energy efficiency services. Furthermore, they examinate the transferability to Jordan, based on the results of a questionnaire among Jordan energy experts. Due to the low level of research knowledge in the specific field, this is an exploratory research approach. The role, challenges and opportunities of Jordan's state-owned National Electric Power Company NEPCO have been highlighted.
This study focuses on smart grids and integration of renewable energy sources in Japan. It first elaborates on the current status of the Japanese power market, its electricity grid, and the trends taking place which result in the need for smart grids. It proceeds with strategic and legislative framework setting relevant for smart grids and renewables, and with current status of smart grids and renewables. Further, it focuses on relevant stakeholders, new business models, and public acceptance relevant for smart grids and renewables. It then puts the Japanese developments in international context and, where possible, compares it to Germany. Lastly, it derives recommendations and identifies where Japanese and German policymakers, regulators and private sector stakeholders might profit from closer collaboration.
In the context of the German-Korean Energy Policy Dialogue, integration of renewable power sources and smart grids have been identified as topics with high relevance. This study aims to support mutual learning and exploration of new fields for collaboration by identifying similarities and differences in the respective status quos, strategies and policies in both countries.
After a short introduction to the South Korean energy situation, Chapter 2 provides an overview of the South Korean power market, its situation regarding renewable power sources and the Korean definition of smart grids. Chapter 3 of this study highlights the major South Korean energy strategies and regulatory frameworks relevant to integration of renewable energies and smart grids. In Chapter 4, the status and perspectives of renewable energy sources integration and smart grids in South Korea are discussed, presenting various demonstrative examples, new business models and the current situation of technology deployment. Chapter 5 puts South Korea in the global context and compares it to Germany. Finally, Chapter 6 draws conclusions and presents recommendations on suitable areas for mutual learning.
More and more cities are setting themselves ambitious climate protection targets, including CO2 neutrality. Schools are important institutions of cities and therefore they have to play a central role in achieving this goal.
With the investment backlog building up and pressure from the Friday for Future movement increasing, the Wuppertal Institute and Büro Ö-quadrat have initiated the project Schools4Future, aiming to support secondary schools to become climate-neutral. In cooperation with secondary school students and teachers, the project team evaluated the existing situation of the participating schools and developed GHG-balances and feasible climate protection concepts. For this purpose, an Excel-based carbon footprint (CF) assessment tool for schools has been developed which is freely available. The tool covers all important emission areas, including heating energy, electricity use, travel to and from schools, school trips, the school canteen and paper consumption. The students were found capable to conduct the CF assessment with the guidance of the teacher, information materials and support of the researchers. So far, six pilot schools have completed their CF assessment with emissions ranging between 335 and 944 kg CO2 per person.
In this paper we present the tool and compare the CF assessment of some schools. We further elaborate on how the tool and project has increased the climate awareness and self-efficacy of students and even stimulated measures by the school board.
To achieve the EU's energy efficiency targets, both the rate of building energy renovation and its depth, i.e., the amount of energy savings post renovation need to be improved. Energy Performance Certificates (EPCs) are key to make energy efficiency measures transparent for the building market and to promote the energy efficiency of buildings through renovation. The revision of the Energy Performance of Buildings Directive (EPBD) is seen as a pre-condition to meet the Renovation Wave objectives and to reach a highly energy efficient and decarbonized building stock by 2050. One focus of the current revision of the EPBD is therefore the improvement of EPCs. QualDeEPC - High-quality Energy Performance Assessment and Certification in Europe Accelerating Deep Energy Renovation, funded under the EU's Horizon 2020 programme, is a project that aims to improve EPCs. Following an EU-wide review of existing EPC schemes, and extensive stakeholder discussions in the seven partner countries, QualDeEPC found that EPCs and EPC schemes need to enhance particularly in the following three ways:
1. Establish a close link between EPCs and deep energy renovation
2. Improve the quality of EPC schemes, i.e., both the EPCs and their data, and the processes of assessment, certification, verification
3. Improve cross-EU convergence of EPC schemes.
