    The study shows that it is possible to transform Germany to both greenhouse gas neutral and resource efficient. One side of the balance is greenhouse gas and raw material saving due to exit from fossil energy carriers and the other is the increased raw material use for the construction of the renewable energy system. In the “GreenEe” scenario it is possible to reduce the GHG emissions in 2050 by 95 % compared to 1990 and the raw material consumption (RMC) by almost 60 % compared to 2010. The study shows also that related ambitious climate and resource efficiency policies helps to achieve both goals. Considering both policy field in a systemic way, should be further discussed and implemented in future politics.

    Resource-efficient pathways towards Greenhouse Gas-Neutrality (RESCUE)
    (Umweltbundesamt, 2020) Nuss, Philip; Günther, Jens; Knoche, Guido; Purr, Katja; Deutschland. Umweltbundesamt
    The RESCUE study describes in six scenarios possible development paths towards a resource-efficient and greenhouse-gas (GHG) neutral Germany until 2050. The GreenSupreme scenario achieves the reduction of emissions along a global 1.5 ˚C path towards GHG-neutrality by 2050, while at the same time substantially lowering Germany's material footprint. This publication discusses possible synergies and overlaps of the transformation areas within RESCUE and the elements of the recently published "European Green Deal". It is hoped to inform stakeholders (e.g., governments, businesses, civil society, and science) with an interest in transformation pathways until 2050. Quelle: https://www.umweltbundesamt.de

    The study shows that it is technically feasible for Germany to become greenhouse gas neutral by 2050. The scenario chosen in the study considers the issue from a purely national perspective and does not include interaction with other countries. Based on a national greenhouse gas reduction target of 95% by 2050 compared to 1990, the study demonstrates that this target can be achieved in Germany by technical means under the given assumptions.

    Die Studie zeigt, dass Treibhausgasneutralität in Deutschland bis 2050 technisch machbar ist. Das in der Studie gewählte Szenario betrachtet dies aus einer rein nationalen Perspektive und bezieht Wechselbeziehungen zu anderen Ländern nicht mit ein. Grundlage der Untersuchung ist ein nationales Treibhausgasminderungsziel bis 2050 von 95 % gegenüber 1990, das - nach den getroffenen Annahmen - durch technische Maßnahmen in Deutschland erreicht werden kann.

    Coal-fired power generation and climate protection until 2030
    (2018) Gibis, Claudia; Hain, Benno; Klaus, Thomas; Knoche, Guido; Landgrebe, Jürgen; Leprich, Uwe; Lünenbürger, Benjamin; Matthey, Astrid; Pfeiffer, David; Purr, Katja; Unnerstall, Herwig; Weiß, Jan; Werlein, Max; Deutschland. Umweltbundesamt
    With this position paper, the ⁠UBA⁠ proposes strategic measures and targeted climate policy instruments for achieving a reduction in coal-fired power generation for the period up until 2030. To achieve a disproportionately high reduction in greenhouse gas emissions by the energy sector as a contribution to achieving the climate protection targets by 2020, the UBA recommends to limit coal-fired power generation to 4,000 full-load hours per year for hard coal and lignite power plants that are at least 20 years old and additional closure of at least 5 GW of the oldest lignite power plants. To ensure that the energy sector comfortably achieves its targeted reduction in greenhouse gas emissions by 2030, the UBA recommends in addition to limit coal-fired power generation the closure of the oldest lignite and hard coal power plants following the Nuclear Power Phase-Out in 2022 to a maximum remaining output of 19 GW.

    Resource-Eficient Pathways towards Greenhouse-Gas- Neutrality - RESCUE
    (Umweltbundesamt, 2019) Günther, Jens; Drosihn, Detlef; Nuss, Philip; Fee, Eric; Balzer, Frederike; Futterlieb, Matthias; Ehlers, Knut; Hain, Benno; Herbener, Reinhard; Günther, Dirk; Hofmeier, Katja; Knoche, Guido; Kristof, Kora; Lange, Martin; Lehmann, Harry; Lambrecht, Martin; Müller, Felix; Obermaier, Nathan; Pfeiffer, David; Plappert, Marie-Luise; Plickert, Sebastian; Proske, Christopher; Purr, Katja; Rechenberg, Bettina; Rudolph, Manuel; Schmied, Martin; Steinbrenner, Joscha; Vollmer, Carla; Werlein, Max; Deutschland. Umweltbundesamt
    The RESCUE study describes in six scenarios possible development paths towards a resource-efficient and greenhouse-gas (GHG) neutral Germany until 2050. For this, assumptions related to the level of ambition for reaching GHG-neutrality, the magnitude of materials- and energy-efficiency, and the implementation of sustainable life-styles are varied. Until 2050, GHG-emissions can be reduced by 95 percent to 97 percent compared to 1990-levels. Net zero emissions can be achieved through sustainable agriculture and forestry management. Primary raw materials consumption is reduced by 56 percent to 70 percent (however, an increased demand for certain raw materials is also observed). This summary report, provides a concise overview of the central assumptions, results, and policy-relevant conclusions from this multi-year research project. Quelle: Bericht

    Setting an ambitious EU climate target for the year 2040
    (Umweltbundesamt, 2023) Lanz, René; Gibis, Claudia; Purr, Katja; Weiß, Jan; Deutschland. Umweltbundesamt
    The European Climate Law (ECL) mandates the European Commission to propose an emission reduction target for 2040 within six months following the first global stocktake referred to in the Paris Agreement, i.e. by May 2024. The ECL obliges the European Commission to take into account the latest and best scientific findings and to take the recommendations by the European Scientific Advisory Board on Climate Change (Advisory Board) as a point of reference for setting the 2040 climate target. This recommendation was published in the Advisory Board's comprehensive report, published in June 2023, and advises a net greenhouse gas (GHG) emissions reduction by 90-95% for the EU by 2040, relative to 1990, corresponding to a 2030-2050 budget of 11-14 Gt CO2eq. The report provides extensive reasoning and scientific evidence how this target range was derived. The German Environment Agency (UBA) welcomes the timely publication of this report and urges the European Commission and European policy makers to follow scientific advice, aim for the most plausible climate ambition and set an intermediate domestic 2040 net GHG emission reduction target of 95%, compared to 1990. However, a discussion that focuses only on the final figure of the 2040 target would not adequately address the intricate nature of GHG reductions and the essential prerequisites for successfully achieving the target. Therefore, the proposal for the 2040 climate target needs to be supplemented with additional information by the European Commission, allowing politics and stakeholders to evaluate the ambition of different target options, to provide clear guidance on the architecture of the target, in particular regarding the relation of emission reductions and carbon sinks, and to address the burden sharing between sectors and member states. Moreover the 2040 target should not be understood as a single-year target only, but rather as a process of continuous ratcheting up of climate ambition with regular reviews and updates.

    Integration of Power to Gas/ Power to Liquids into the ongoing transformation process
    (2016) Adlunger, Kirsten; Burger, Andreas; Hain, Benno; Klaus, Thomas; Lange, Martin; Lehmann, Harry; Mönch, Lars; Osiek, Dirk; Proske, Christopher; Purr, Katja; Schmied, Martin; Vollmer, Carla
    Power to gas (PtG) is a technology for producing hydrogen and methane using electricity, while power to liquids (PtL) is an electricity-based process for the generation of liquid fuels. Jointly with other so-called power-to-x technologies PtG and PtL make it possible to provide renewable energies for all applications. This position paper assesses the role and prospects of the power-to-gas/power-to-liquids (PtG/PtL) technology in a fully renewable energy system and identifies, in particular, the challenges for integration and further development of this technology in the ongoing transformation process, which should be addressed in the next few years.

    Carbon Capture and Storage (CCS)
    (Umweltbundesamt, 2023) Purr, Katja; Spindler, Joris; Deutschland. Umweltbundesamt; Brieschke, Jens; Damian, Hans-Peter; Frauenstein, Jörg; Ginzky, Harald; Herrmann, Bianca; Kahrl, Andreas; Ruddigkeit, Dana; Messner, Dirk; Alsleben, Carsten; Berger, Juliane; Dröge, Susanne; He, Ling; Kleiner, Larissa; Ulrich, Mathias; Tambke, Jens; Schultz, Karlotta
    The UBA position paper assesses the usefullness of carbon capture and storage (CCS for short) as a climate protection instrument. It describes guidelines for sustainable use, as well as the necessary monitoring and risk prevention. The effects of CCS on human health and the environment are also considered. According to the paper, CCS cannot replace greenhouse gas reductions and the rapid phase-out of fossil fuels. CCS must also not lead to perpetuate fossil energy supply structures and hinder the expansion of renewable energies. The UBA therefore proposes that the technology should first be tested in waste incineration plants where heat and electricity are generated from non-recyclable waste, but where CO2 is also produced.
