Abstract

Aktuell fordern Wirtschaftsverbände, das Zieljahr Deutschlands für das Erreichen der Klimaneutralität von 2045 auf 2050 zu verschieben und damit das nationale Ziel dem Klimaneutralitäts-Ziel der Europäischen Union anzugleichen. Für diese Forderung gibt es gute Gründe, wie in diesem Beitrag erläutert wird, allen voran immense Kosteneinsparungen für die deutsche Volkswirtschaft. Eine Verschiebung wäre aber auch deshalb geboten, weil eine effektive Klimapolitik, die etwas im globalen Maßstab bewirkt, nur in internationaler Kooperation möglich ist, nicht aber im nationalen Alleingang (Ockenfels, Schmidt 2019). Angesichts der mit einer zeitlich überambitionierten Klimapolitik einhergehenden Herausforderungen stellt sich die Frage, warum Deutschland die damit verbundenen Risiken und Kosten eingehen sollte, wenn die daraus resultierenden Treibhausgaseinsparungen im globalen Maßstab betrachtet allenfalls symbolischer Natur sein können. Diese Frage stellt sich umso mehr, als die Vorreiterrolle gravierende kontraproduktive Rückwirkungen für Deutschland haben kann, allen voran den möglichen Verlust an gesellschaftlicher Akzeptanz für die Klimapolitik.
