Die Optionen werden identifiziert, um die Umweltintegrität des Systems zu gewährleisten. Eine klare Formulierung der EUC ist wichtig, um Minimalanforderungen für die Qualität von Klimaschutzzertifikaten für CORSIA sicherzustellen. Die Analyse fokussiert sich auf fünf Kriterien, die essentiell für die Qualität von Klimaschutzzertifikaten sind: Beweis der Zusätzlichkeit, Festlegung von Referenzszenarien, Dauerhaftigkeit der Minderungen, Vermeidung von Doppelzählung, und die Vermeidung von Nettoschäden. Für die Bewertung der derzeitigen EUC wird die Praxis der größten Crediting Programme ausgewertet und Bereiche identifiziert, in denen die EUC überarbeitet, verfeinert oder weiter ausgearbeitet werden können, um die Praxis der Crediting-Programme zu berücksichtigen. Es werden außerdem spezifische Empfehlungen für die Überarbeitung, Ergänzung und Verfeinerung von jedem Kriterium erstellt, einschließlich von Formulierungsvorschlägen. Insgesamt sind die derzeitigen EUCs ausreichend, um die wesentlichen konzeptionellen Elemente jedes Kriteriums abzudecken. Allerdings könnten alle fünf Kriterien weiter ausgearbeitet werden, um essentielle Anforderungen und Verfahren zu spezifizieren, damit die Kriterien tatsächlich erfüllt werden. In den meisten Fällen können die Formulierungen und die Terminologie der EUCs auch verbessert werden. Quelle: ForschungsberichtThis discussion paper assesses options for improving the current Emissions Unit Eligibility Criteria (EUCs) used for the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) adopted by the International Civil Aviation Organization (ICAO), with the goal of ensuring the scheme's environmental integrity. Clearly articulated EUCs are needed to define minimum standards for the "quality" of carbon offset credits that may be used under CORSIA. For this analysis, we focus on five EUCs that are essential for offset credit quality: additionality; baselines; permanence; avoidance of double counting; and causing no net harm. To evaluate the current EUCs, we review current practice among major carbon offset programs, and identify areas where the EUCs could be revised or elaborated to better align with best practices. We then provide specific recommendations for revision, refinement, or elaboration to improve each EUC, including suggested text edits and additions. We find that the current EUCs are mostly sufficient in covering basic conceptual elements for each of the criteria. However, all of the EUCs reviewed here could benefit from more elaboration on essential program requirements and procedures needed to ensure that the criteria are realized. In most cases, the formal wording and terminology used in the EUCs could also be improved. Quelle: ForschungsberichtThis discussion paper assesses how robust accounting could be implemented under the Paris Agreement in order to avoid double counting between nationally determined contributions (NDCs) and the Carbon Offsetting and Reduction Scheme for International Aviation (⁠CORSIA⁠) implemented under the International Civil Aviation Organization (ICAO). The paper focuses on how host countries of carbon-offset projects can account for the use of offset credits under CORSIA by reporting 'adjustments' in the 'structured summaries' of their biennial transparency reports prepared under Article 13 of the Paris Agreement. The paper finds that several accounting approaches considered in the international negotiations on Article 6 of the Paris Agreement for international transfers of mitigation outcomes between countries cannot not be implemented in the specific context of CORSIA where the offset credits are used by airline operators or may not robustly avoid double counting. The paper identifies nine options for how the use of offset credits under CORSIA could be accounted for by host countries and discusses their advantages and disadvantages. The paper also evaluates options to account for single-year targets in the context of CORSIA, as well as options for consistent consideration of Global Warming Potentials used under CORSIA and nationally determined contributions under the Paris Agreement. The findings of the paper are important for the ongoing negotiations under the Paris Agreement on the rules for international transfers of mitigation outcomes under Article 6 and the implementation of 'structured summaries' under Article 13.1 Onlineressource (42 Seiten)online resourceenghttp://rightsstatements.org/vocab/InC/1.0/Internationale LuftfahrtCorsiainternational aviationdouble countingParis AgreementArticle 6 of the Paris AgreementForschungsberichtClimate | Energy
