TY - JOUR A1 - Leipprand, Anna A1 - Flachsland, Christian A1 - Pahle, Michael T1 - Energy transition on the rise : discourses on energy future in the German parliament JF - Innovation: The European Journal of Social Science Research N2 - In this paper we describe energy policy discourses and their story-lines in German parliamentary debates, and trace their evolution over the past decades. Through content analysis and coding with MAXQDA, changes in the discourses and in the use of story-lines by different political parties are analyzed. Our study shows that while the concept of a transition towards a nuclear-free, renewables-based energy system became hegemonic within three decades, the discourse itself underwent major changes. Energy Transition was de-radicalized and became part of a discourse of Ecological Modernization, thus aligning with mainstream economic logic. There are still considerable differences in the story-lines narrated by parliamentarians about pathways to Energy Transition and its effects. Discursive struggles into the meaning and the means of the transition project continue, suggesting that discourse structuration is far from complete.

T1 - Systematic review and meta-analysis of ex-post evaluations on the effectiveness of carbon pricing JF - Nature Communications N2 - Today, more than 70 carbon pricing schemes have been implemented around the globe, but their contributions to emissions reductions remains a subject of heated debate in science and policy. Here we assess the effectiveness of carbon pricing in reducing emissions using a rigorous, machine-learning assisted systematic review and meta-analysis. Based on 483 effect sizes extracted from 80 causal ex-post evaluations across 21 carbon pricing schemes, we find that introducing a carbon price has yielded immediate and substantial emission reductions for at least 17 of these policies, despite the low level of prices in most instances. Statistically significant emissions reductions range between –5% to –21% across the schemes (–4% to –15% after correcting for publication bias). Our study highlights critical evidence gaps with regard to dozens of unevaluated carbon pricing schemes and the price elasticity of emissions reductions. More rigorous synthesis of carbon pricing and other climate policies is required across a range of outcomes to advance our understanding of “what works” and accelerate learning on climate solutions in science and policy.

Wie Lenkungssteuern effektiv und gerecht für den Klima- und Umweltschutz ausgestaltet werden können JF - Perspektiven der Wirtschaftspolitik N2 - Steuern und Abgaben auf Produkte oder Verbrauch mit gesellschaftlichen Folgekosten (externe Kosten) – sogenannte Pigou- oder Lenkungssteuern – sind ein gesellschaftliches „Win-Win-Instrument“. Sie verbessern die Wohlfahrt und schützen gleichzeitig die Umwelt und das Klima. Dies wird erreicht, indem umweltschädigende Aktivitäten einen Preis bekommen, der möglichst exakt der Höhe des Schadens entspricht. Eine konsequente Bepreisung der externen Kosten nach diesem Prinzip könnte in Deutschland erhebliche zusätzliche Einnahmen erbringen: Basierend auf bisherigen Studien zu externen Kosten wären zusätzliche Einnahmen in der Größenordnung von 348 bis 564 Milliarden Euro pro Jahr (44 bis 71 Prozent der gesamten Steuereinnahmen) möglich. Die Autoren warnen allerdings, dass die Bezifferung der externen Kosten mit erheblichen Unsicherheiten verbunden ist. Damit Lenkungssteuern und -abgaben ihre positiven Lenkungs- und Wohlstandseffekte voll entfalten können, seien zudem institutionelle Reformen notwendig.
