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...

Recent research has shown that agreements centered on the adoption of breakthrough technologies can break the deadlock in international climate negotiations if the mitigation technology exhibits a network externality that transforms full cooperation into a self-enforcing outcome. This paper...

To stay within the 2êC temperature increase target for climate change calls for ambitious emission reduction targets already for the 2012-2020 compliance period. Cost-efficiency is a crucial criterion for the enforcement of such ambitious targets, requiring analyses of all possible abatement...

The paper looks at the global environment as a public good and as a sink for CO2-emissions. It discusses problems to be solved in institutional arrangements to protect global environmental media and looks at criteria for allocating the costs of emission reduction and emission rights. It analyzes...

To show global leadership and to foster the international negotiations for a long term international climate regime the EU has decided to reduce its GHG emissions by 20% relative to 1990 until the year 2020. These reductions will even rise to 30% if there is an international agreement committing...

To meet their Kyoto targets under the Burden Sharing Agreement, most European countries plan to make use of the flexible project mechanisms "Clean Development Mechanism" (CDM) and "Joint Implementation" (JI). In addition, CDM and JI credits can be used by installations to fulfil their...

We estimate CO2 implicitly contained in traded commodities based on the GTAP 7 data: While net carbon imports into the industrialized countries amount to 15% of their total emissions, net carbon exports of the developing countries amount to 12% of their total emissions, and net carbon exports of...

The policy instruments for emissions reductions will be an integral part of a Post Kyoto Climate Regime. In this paper we compare a harmonized international carbon tax to a cap and trade system with different allocation rules for the emission caps. The caps are based either on the requirement...

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...

This study attempts a numerical simulation of potential CCS (carbon dioxide capture and storage) use by using a modified version of the DICE (Dynamic Integrated model on Climate and Economy) model (Nordhaus, 1994; Nordhaus and Boyer, 2000). In DICE, CO2 emissions are controlled to the extent in...
