A method is presented for computing long-term greenhouse gas emission pathways for both industrial ("Annex B") countries and developing ("non-Annex B") countries. This method combines two main factors: (i) climate protection goals, in the form of targets for stabilising CO2 in the atmosphere,...

The 27th Conference of the Parties (COP 27) to the United Nations Framework Conven­tion on Climate Change (UNFCCC) in Sharm el-Sheikh, Egypt, was marked by multiple crises and the shaken confidence of developing countries in the multilateral process. Nonetheless, an agreement was reached on...

Climate physics predicts that the intensity of natural disasters will increase in the future due to climate change. One of the biggest challenges for economic modeling is the inherent uncertainty of climate events, which crucially affects consumption, investment, and abatement decisions. We...

Dieser Aufsatz argumentiert, dass die deutsche EE-Förderung auf einer falschen Konzeption beruht. Sie hat sich vorwiegend befehlswirtschaftlicher Methoden bedient und eine Staatsschuldillusion zu erzeugen versucht. Es verwundert infolgedessen nicht, dass enorme Kosten entstanden sind,...

Cities are not affected by global climate policy and the Kyoto Protocol – however many of them engage in voluntary activities. This paper analyses how communities in general and especially the city of Hamburg can contribute to global climate protection in their citypartnerships according to...

As GHG emissions did not decline as anticipated early of the 1990ties Carbon Capture and Storage (CCS) recently gained more and more attention as a climate change mitigation option. However, CO2 suppressed in geological reservoirs is likely to lead to future releases of the CO2 stored. This...

International concern about climate change has led to the Kyoto Protocol, negotiated in 1997, which contains legally binding emission targets for industrialized countries to be achieved during the commitment period 2008-2012. While proponents of the Protocol celebrate it as a breakthrough in...

We investigate the importance of ?what?-flexibility on top of ?where?- and ?when?-flexibility for alternative emission control schemes that prescribe long-term temperature targets and eventually impose additional constraints on the rate of temperature change. We find that ?what?-flexibility...
