    Kohleverstromung und Klimaschutz bis 2030
    (2017) 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
    Mit diesem Thesenpapier schlägt das Umweltbundesamt strategische Maßnahmen und zielgerichtete Instrumente zur Reduzierung der Kohleverstromung für den Zeitraum bis 2030 vor. Für eine stark überproportionale Treibhausgasminderung der Energiewirtschaft als Beitrag, um die Klimaschutzziele bis 2020 zu erreichen, empfiehlt das ⁠UBA⁠ die Stromerzeugung auf 4000 Volllaststunden pro Jahr für Stein- und Braunkohlekraftwerke mit einem Alter von mindestens 20 Jahren zu begrenzen und mindestens 5 GW der ältesten Braunkohlekraftwerke zusätzlich zu den ohnehin geplanten Stilllegungen stillzulegen. Um das Ziel für die Treibhausgasminderung der Energiewirtschaft bis 2030 robust zu erreichen, empfiehlt das UBA zusätzlich zur Volllaststundenbegrenzung sukzessive weitere der ältesten Braun- und Steinkohlekraftwerke nach dem Kernenergieausstieg 2022 stillzulegen und auf maximal 19 GW Gesamtleistung zu reduzieren.

    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.

    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.
