Seeking to play a pioneering role in climate protection, the European Union has decided to pursue a reduction of at least 20% in greenhouse-gas emissions (on 1990 levels) by the year 2020. Moreover, Europe has declared its willingness to commit itself to emission reductions of 30% over the same...

Europa will Vorreiter beim Klimaschutz werden und hat sich entschlossen, die Treibhausgasemissionen bis zum Jahr 2020 um mindestens 20 % gegenüber dem Jahr 1990 zu senken. Darüber hinaus ist die Europäische Union bereit, sich für diesen Zeitraum auf eine Verminderung um 30 % zu verpflichten,...

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...

Policies of lowering carbon demand may aggravate rather than alleviate climate change (green paradox). In a two-period three-country general equilibrium model with finite endowment of fossil fuel one country enforces an emissions cap in the first or second period. When that cap is tightened the...

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...

This paper examines whether the climate policy options policymakers are contemplating are compatible with core principles of the world trading system set forth in the General Agreement on Tariffs and Trade (GATT), the World Trade Organization (WTO), and Appellate Body decisions. The authors...
