Diminishing emission budgets and increasing risks of catastrophic damages from climate change require analyses of rapid response options including geoengineering options such as ocean iron fertilization (OIF). To decide whether or not OIF might be such an option an assessment of its potential as...

Despite large uncertainties in the fertilization efficiency, natural iron fertilization studies and some of the purposeful iron enrichment studies have demonstrated that Southern Ocean iron fertilization can lead to a significant export of carbon from the sea surface to the ocean interior. From...

Control of carbon dioxide emissions in developing countries is becoming a key issue in the international climate policy. A critical element for achieving substantial emission reduction in those countries is the installment of new energy technologies. Drawing on the framework of poverty-trap...

The European emissions trading scheme (EU-ETS) for CO2 is the largest existing emissions trading scheme in the world. The main reason for the implementation of this scheme is to reach the European Kyoto targets at minimal cost and to establish a price for emissions. The right to emit CO2...

CO2 emissions from international shipping, which are currently unregulated, are predicted to rise from 2.7% today to 18% in 2050. International bunker fuel emissions have been excluded from any commitment in the Kyoto Protocol; the UNFCCC conference in Copenhagen also failed to bring about clear...

In order to reach the two degree target it is necessary to control CO2 emissions also in fast growing emerging economies such as India. The question is how the Indian economy would be affected by e.g. including the country into an international climate regime. Existing analyses with either a...

Control of carbon dioxide emissions in developing countries is becoming a key issue in the international climate policy. A critical element for achieving substantial emission reduction in those countries is the installment of new energy technologies. Drawing on the framework of poverty-trap...

We develop a comprehensive wealth index for cities that measures their endowment with environmental, energy, social, human, and economic capital stocks. We apply this index to the 100 largest autonomous cities in Germany. We find that (i) a good economic performance does not need to come at the...

One major challenge when conducting contingent valuation studies in developing countries is the choice of the appropriate payment vehicle. Since regular cash-income does not exist for the majority of the population and market integration is low, households in rural areas have less experience...
