This paper discusses structure, impact, costs, and efficiency of renewable energy supply in the eight largest advanced economies (the G-7 plus Spain), with focus on Germany. Renewables production costs are compared to benefits, defined as reductions in net carbon emissions; technological...

Die Abholzung der weltweiten Wälder ist nach der Verbrennung fossiler Brennstoffe die zweitgrößte anthropogene CO2-Quelle. Maßnahmen der UN, die unter dem Namen »REDD« zusammengefasst werden, sollen der Abholzung entgegenwirken. Der Beitrag beschreibt die Funktionsweise von REDD und gibt...

Die Rubrik »Kurz zum Klima« erscheint nun bereits seit drei Jahren mit nahezu 60 Ausgaben. Dieser Beitrag greift drei Themen aus den Bereichen Energie-, Klima- und Umweltpolitik – das Reserven-Produktions-Verhältnis, die weltweite CO2-Reduktion und das Problem der Überfischung – erneut...

Marginal abatement cost curves (MACCs) are a favorite instrument to analyze international emissions trading. This paper focusses on the question of how to define MACCs in a general equilibrium context where the global abatement level influences energy prices and in turn national MACCs. We...

This paper fills a gap in the macroeconomic literature on renewable sources of energy. It offers a definition of green investment and analyzes the trends and determinants of this investment over the last decade for 35 advanced and emerging countries. We use a new multi-country historical dataset...

We derive non-cooperative Nash equilibrium (NE) importer and exporter petroleum excise taxes given full within-group tax coordination, but no coordination between groups, assuming that importers do not produce and exporters do not consume petroleum, and petroleum consumption causes a global...

Fiscal instruments are potentially among the most effective, and cost-effective, options for addressing externalities related to poor air quality, urban road congestion, and greenhouse gases. This paper takes a case study, focused on Mauritius (a pioneer in the use of green taxes) to illustrate...
