This paper presents results from a model intercomparison exercise among regionalized global energy-economy models conducted in the context of the RECIPE project. The economic adjustment effects of long-term climate policy aiming at stabilization of atmospheric CO2 concentrations at 450 ppm are...

In the debate on post-Kyoto global climate policy, intensity targets, which set a maximum amount of emissions per GDP, figure as prominent alternative to Kyoto-style absolute emission targets, especially for developing countries. This paper re-examines the case for intensity targets by...

This paper summarizes results from ten global economy-energy-environment models implementing mechanisms of endogenous technological change (ETC). Climate policy goals represented as different CO2 stabilization levels are imposed, and the contribution of induced technological change (ITC) to...

This paper assesses endogenous technical change (ETC) in climate-economy models, using the models in the Innovation Modeling Comparison Project (IMCP) as a representative cross-section. ETC is now a feature of most leading models. Following the new endogenous growth literature and the...

There is an emerging planetary consensus: Climate protection is necessary. Preventing global mean temperature from rising more than 2°C above pre-industrial levels is a common goal of climate protection. In essence, it requires a stabilization of carbon dioxide emissions within the next two...

The prospects for cooperation on climate protection beyond 2012 are currently uncertain. Thus policy instruments which foster participation in International Environmental Agreements (IEA) are in demand. Among the instruments under discussion are trade sanctions. Multi-region optimal growth...

Die Abscheidung und Lagerung von CO2 wird zunehmend als Option im Rahmen einer Klimaschutzstrategie diskutiert. Wie sicher und wie wirksam ist diese Methode? Ottmar Edenhofer, Brigitte Knopf und Matthias Kalkuhl, Potsdam-Institut für Klimafolgenforschung, Berlin, machen deutlich, dass die...

MIND is a hybrid model incorporating several energy related sectors in an endogenous growth model of the world economy. This model structure allows a better understanding of the linkages between the energy sectors and the macro-economic environment. We perform a sensitivity analysis and...
