    Carbon Capture and Storage (CCS) - Diskussionsbeitrag zur Integration in die nationalen Klimaschutzstrategien
    (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
    Das UBA-Positionspapier beurteilt den Nutzen des Abscheidens und Speicherns von CO2 (kurz CCS , für Englisch "Carbon Capture and Storage") als Klimaschutzinstrument und beschreibt Leitplanken für einen nachhaltigen Einsatz, ebenso wie das nötige Monitoring und die Risikovorsorge. Auswirkungen von CCS auf menschliche Gesundheit und die Umwelt werden ebenfalls betrachtet. CCS kann laut Papier Treibhausgasminderungen und den schnellen Ausstieg aus fossilen Techniken nicht ersetzen. CCS darf auch nicht dazu führen, fossile Energieversorgungsstrukturen zu verfestigen und den Ausbau der Erneuerbaren Energien zu behindern. Das UBA schlägt daher vor, die Technik zunächst in Müllverbrennungsanlagen zu testen, in denen aus nicht recycelbarem Abfall Wärme und Strom erzeugt wird, aber auch CO2 anfällt.

    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.

    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.
