The European Commission published its long-term strategic vision for climate policy "A Clean Planet for all" in 2018 which lays out various pathways for a transition to achieve net-zero greenhouse gas emissions in the whole energy sector and economy by 2050. The vision emphasizes that that a net-zero target by 2050 is extremely challenging for all sectors including the built environment. In this context the aim of this paper is to describe and analyze the EU Renovation Wave Initiative of the European Commission as central puzzle piece, which is also the main driver behind the targeted revision of the Energy-Performance of Buildings Directive (EPBD) in 2021. On the one hand the Renovation Wave is put into context within the overall EU policy landscape, on the other hand the ambition, targets and policy options are compared with the overall ambition and to what science says. Main objective of the Renovation Wave is to at least double the current renovation rates of public and private buildings by 2030 and foster deep renovations. Together with a very ambitious decarbonization of heating this should enable to cut direct building sector greenhouse-gas emissions by 60% until 2030 (based on 2015 levels) as laid down in the Climate Target Plan 2030 (CTP). Apart from elements in the EPBD, also the RED and EED revisions as well as carbon pricing should make sure that the adequate framework for this very ambitious decarbonization is given. Currently, the progress and activities on the ground and in the renovation market are not at all in line what is defined as target-compliant within the strategy, neither with regard to the quality of renovations, nor the quantity of it. The implementation in the market will show whether the strategy can be successfully applied.

Die Untersuchung beschreibt die technischen und wirtschaftlichen Vorteile, Folgen und Grenzen des breiten Wärmepumpeneinsatzes aus einzelwirtschaftlicher wie aus Energiesystem-Perspektive - ohne jeden Einzelfall abzubilden. Hierzu werden zunächst Wärmepumpensysteme in Bestandsgebäuden detailliert und zeitlich hoch aufgelöst simuliert, bevor Ableitungen und Politikempfehlungen formuliert werden. Zudem werden die Ergebnisse einer Online-Umfrage zu Wärmepumpen dargestellt und Finanzierungs- und Förderinstrumente für Investitionen in Wärmepumpen beschrieben.

In November 2018, the European Commission published its Strategic Long-Term Vision entitled "A Clean Planet for all" calling for the target of net-zero greenhouse gas emissions by 2050. This proposal was subsequently agreed upon by EU heads of state and government, it features centrally in the European Green Deal and has now been made a legally binding objective in the EU Climate Law. The Strategic Long-Term Vision was supported by a detailed In-depth Analysis. The central objective of the work presented in this report was to assess the European Commission's Strategic Long-Term Vision and supplementary materials and reflect on them in light of state-of-the-art sector analyses. The report is a summary of a series of publications. These publications provide insights on the In-depth Analysis along with an assessment of the role of the Strategic Vision and how it can be turned into an effective long-term strategy for the EU. In addition, sector analyses for the transport sector, the industry sector and the buildings sector provide insights on the action needed to reach long-term decarbonisation in those sectors. An assessment of the inception impact assessment to the Effort Sharing Regulation shed light on different options for a meaningful combination of CO2 pricing (emissions trading) and regulation under the Effort Sharing Regulation. Lastly, a stocktake on the overall landscape of EU climate governance as of autumn of 2021 identified remaining weaknesses and recommends ways to strengthen the existing processes to ensure that they can get the EU on a path towards climate neutrality. A central recommendation is the call for an update to the EU long-term strategy as a central hub to provide oversight and guidance for sectoral and horizontal strategies as well as the next policy package (beyond 2030) that is due in 2024.

Heat Roadmap Europe 3 is from work package 2 of the STRATEGO project (http://stratego-project.eu/). It quantifies the impact of implementing various energy efficiency measures in the heating and cooling sectors of five EU Member States: Czech Republic, Croatia, Italy, Romania, and the United Kingdom. These countries vary considerably in terms of population, climate, resources, and energy supply, so the key results, conclusions, and recommendations presented in this report can inform national energy policy across all of Europe. The results from this study indicate that a total investment of approximately €1.1 trillion in energy efficiency measures across all five of these countries, between 2010 and 2050, will save enough fuel to reduce the costs of their energy systems. After considering both the initial investment and the resulting savings, the total annual cost of the heating, cooling, and electricity sectors is reduced by an average of ~15% in each country. These initial investments are primarily required in heat savings for the buildings, district heating in urban areas, and electric heat pumps in rural areas. In essence, energy efficiency measures in the heating sector will enable EU Member States to simultaneously reduce energy demand, imported fossil fuels, carbon dioxide emissions, and the cost of the heating, cooling, and electricity sectors.

In 2018, the European Commission presented its long-term Strategic Vision "A clean planet for all", which calls for net-zero greenhouse gas emissions (GHG) of the European Union by 2050. The Strategic Vision is accompanied by the In-depth Analysis containing a detailed impact assessment based on a scenario analysis. This paper presents the findings of an assessment of the In-depth Analysis, in particular its suitability as the analytical input for the Strategic Vision. In summary, the In-depth Analysis covers the key aspects for building an adequate long-term climate strategy and is thus a strong foundation for the Strategic Vision, in spite of certain limitations. The presented pathways to net-zero emissions cover all the relevant sectors and GHGs and are in accordance with other studies. However, they are not fully assessable, because important input and output data are not provided for all scenarios. Moreover, it is unclear why none of the scenarios maximises the use of renewable energies. The variety of models used provides evidence for the economic feasibility of such a transition. In this regard, the restricted set of scenarios used for the macro-economic assessment is a shortcoming. In the scenarios with net-zero GHG emissions in 2050, all sectors have to pursue very ambitious emission reductions early on. Nonetheless, some remaining GHG emissions have to be compensated by a combination of natural and artificial carbon sinks. Detailed considerations of the economic and social implications of the mitigation scenarios show moderate impacts on GDP and labor in comparison to other societal drivers, but also indicate the need for a strong shift from consumption to investment in mitigation technologies and infrastructure. International cooperation is seen as essential to foster the transformation to net-zero GHG emissions.
