The International Climate Regime and Its Driving-Forces : Obstacles and Chances on the Way to a Global Response to the Problem of Climate Change

The greenhouse effect is a vital process which is responsible for the heat on the earth's surface. By consuming fossil fuels, clearing forests etc. humans aggravate this natural process. As additionally trapped heat exceeds the earth's intake capacity this consequently leads to global warming. The current concentration of CO2 in the atmosphere is already 30% higher compared to pre-industrial levels and unmanaged this development is likely to result in an increase of up to 6.4 C towards the end of the century. Especially the poorest regions of the world are facing a double inequity as they a) will be hit earliest and hardest by the adverse impacts of climate change, and b) are least responsible for the stock of current concentrations in the atmosphere. Seeing this the application of the precautionary principle telling us 'to better be safe than sorry" appears to be imperative and makes traditional cost-benefit analysis become obsolete. Thus combating global warming has become one of the most important issues facing the world in the 21st century. The international climate regime is the main platform to further cooperation between nations and to tackle this problem. Since the first world climate conference in 1979 the international community of states pursues the goal of stabilizing greenhouse gas emissions. In 2009, the 15th COP of the UNFCCC aimed at achieving the final breakthrough with regard to framing new long-term mitigation commitments. However, the regime theory tells us that states behave as rational egoists and solely follow selfishly defined interests to maximize own profits. So it not only has to be assumed that just states with a favourable benefit-cost ratio will take the role of a 'pusher" in international climate negotiations but also that powerful states are more likely to reach a favourable outcome. Indeed the highly ineffective Kyoto Protocol, which amongst others had to deal with the exit of the United States, the creation of 'hot air" reduction
