Two decades have passed since the Clean Air Act Amendments of 1990 launched a grand experiment in market-based environmental policy: the SO2 cap-and-trade system. That system performed well but created four striking ironies. First, by creating this system to reduce SO2 emissions to curb acid...

This article constitutes a new contribution to the analysis of overlapping instruments to cover the same emission sources. Using both an analytical and a numerical model, we show that when the risk that the CO2 price drops to zero and the political unavailability of a CO2 tax (at least in the...

Megacities already account for a major part of global energy-related CO2 emissions with a strong tendency to increase; hence, future climate policy has to put a special emphasis on reducing big cities' energy consumption, especially in a world, where global climate negotiations are deadlocked....

In den USA, weltweit zweitgrößte Wirtschaftsmacht und gleichzeitig zweitgrößter Emittent von Treibhausgasen, war die Regierungsübernahme durch die Obama-Administration im Jahr 2008 geprägt von großen Hoffnungen nach der klimapolitischen Abstinenz der Bush-Regierung (Moslener/Sturm 2008,...

From 1 January 2005 onwards the European Union has launched the first largescale international carbon emissions trading program. As the EU Emissions Trading Scheme (EU-ETS) covers only part of domestic carbon emissions, it implies a hybrid environmental regulation scheme: Each EU Member State...

In the absence of an international agreement on climate policy, unilateral carbon abatement creates two problems: It tends to have a detrimental effect on domestic competitiveness, and it leads to an increase in carbon emissions abroad (leakage). This paper analyses two policies that have...

The 'Climate action and renewable energy package' proposed by the European Commission in the beginning of 2008 suggests auctioning as basic principle for allocation for the upcoming third trading phase of the EU Emissions Trading Scheme that runs from 2013 to 2020. Overall, it is estimated that...

Ambitious unilateral EU environmental policy has raised concerns about adverse competitiveness implications for European energy-intensive and export-oriented sectors. We analyze the economic and environmental implications of two different measures to address these concerns in the EU Emission...

This discussion paper reviews the literature on experiences with innovation under the existing emissions trading schemes in the USA. The basic result from this review is that the innovation effects triggered by emissions trading have been limited because a) targets were not constraining in the...

Öffentlichkeit und Politik müssen häufig den Eindruck gewinnen, dass Wirtschaftswissenschaftler bei zentralen wirtschaftspolitischen Fragen keine Einigkeit erzielen können. Dies gilt nicht zuletzt für die Umsetzung der Energiewende. Dieser Beitrag nutzt die öff entlich zugänglichen...
