Net-zero climate policies foresee deployment of atmospheric carbon dioxide removal wit geo-logical, terrestrial, or marine carbon storage. While terrestrial and geological storage would be governed under the framework of national property rights, marine storage implies that carbon is transferred...

This paper opens with a short recollection of the Kiel Week Conference of 2002, recorded in a volume edited by Horst Siebert, titled Global Governance: An Architecture for the World Economy. Assess-ments and forecasts made at that time are scored against subsequent developments. Security...

In the past years biofuels have received increased attention since they were believed to contribute to rural development, energy security and to fight global warming. It became also clear, though, that bioenergy cannot be evaluated independently of the rest of the economy and that national and...

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...

Biofuels and other forms of bioenergy have received increased attention in recent times: They have partly been acclaimed as an instrument to contribute to rural development, energy security and to fight global warming but have been increasingly come under attack for their potential to contribute...

In the presence of rising carbon concentrations more attention should be given to the role of the oceans as a sink for atmospheric carbon. We do so by setting up a simple dynamic global carbon cycle model with two reservoirs containing atmosphere and two ocean layers. The net flux between these...

We apply standardized numerical techniques of stochastic optimization (Judd [1998]) to the climate change issue. The model captures the feature that the effects of uncertainty are different with different levels of agent's risk aversion. A major finding is that the effects of stochasticity...

Ocean iron fertilization is currently discussed as a potential measure to mitigate climate change by enhancing oceanic CO2 uptake. Its mitigation potential is not yet well explored, and carbon offsets generated through iron fertilization activities could currently not be traded on regulated...

In the next years several power plants throughout Europe have to be replaced and the questions is whether to build coal fired power plants with carbon capture and storage (CCS). In a study for the city of Kiel in northern Germany only a 800 MW coal power plant reaches a required minimum...

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...
