Abstract

Dieser Beitrag spiegelt die in englischer Sprache gehaltene Thünen-Vorlesung von Ottmar Edenhofer auf der Jahrestagung des Vereins für Socialpolitik am 16. September 2024 in Berlin unter dem Titel „The (Missing) Third Pillar“ wider. Der Klimaökonom zeigt auf der Basis der gemeinsamen Forschung mit Matthias Kalkuhl, dass die internationale Klimapolitik vor einem Paradigmenwechsel steht: Durch CO2-Entnahmen („carbon dioxide removal“, CDR) sollen zusätzliche natürliche und technische Kohlenstoffsenken bereitgestellt werden, weil andernfalls die ambitionierten Klimaziele des Pariser Klimaabkommens nicht zu erreichen sind. CDR hat darüber hinaus die Funktion, die globale Kooperation zu erleichtern. Die Autoren entwickeln einen Vorschlag, wie eine Europäische Kohlenstoffzentralbank – die European Carbon Central Bank (ECCB) – eine Schlüsselrolle für Europas Beitrag zu einer planetarischen Müllabfuhr einnehmen kann. Den ökonomischen Anreiz liefern Clean-Up-Zertifikate, die die CO2-Entnahmen im EU-Emissionshandel finanzieren sollen.
