The Global Warming Potential index applied in the Kyoto Protocol to compare emissions of greenhouse gases has been debated and various alternatives have been proposed. In this paper we give a brief overview of some of these alternatives. We discuss the adequacy of these indices and seek to evaluate their relevance and applicability in a future climate regime. Their performance is assessed according to guidelines given in the UN Framework Convention on Climate Change (UNFCCC) and in terms of political feasibility. We find that some of the alternative approaches to the GWP concept are more adequate in terms of effective mitigation of human-induced climate change but have a lower political feasibility.
