Cluster "Mitigation Strategies"

The framing part of the second cluster, emission scenarios and mitigation strategies, consists of synthesizing climate system knowledge for policy relevant questions in the mitigation context, international affairs, law, and scenario analysis on a regional and global level. This cluster will strongly focus on the international and national policy context for an energy market transition towards a zero carbon economy. On a general, international level, international effort sharing proposals by government will be analyzed regarding multiple fairness, equity, capacity and historical contribution indicators. For example, the possible solution space for any agreement within the BASIC country (Brazil, South Africa, India and China) proposal on equal cumulative per capita emissions will be explored – while taking into account financial transfer payments. This work stream hence builds the framework for national emission pathways and energy systems in cluster I. The probabilities of different mitigation pathways to attain climate targets, emission budgets, the global technological options for mitigation beyond energy markets, the societal uptake of mitigation strategies and the implications of mitigation (in-)action in the near-term for the feasibility and costs of achieving long-term climate targets are examples for this cluster’s research projects. The framework will allow investigating cost-optimal and second-best pathway options that take into account present-day lock-in effects as well as other political decisions not related to climate change.
