Attempts to implement 2°C-target-compatible emission reductions via international cooperation have not been very successful so far, as evidenced by the Kyoto Protocol and the negotiations on a post-Kyoto agreement. The CORE project analyses whether global cooperation is possible under the current setting of international negotiations on climate change, i.e. if it is possible to design a climate regime where long-term climate targets may be met and all countries agree on the distribution of reduction efforts. This is done using cooperative game theory in combination with a computable general equilibrium model, taking into account the uncertainty about key mitigation technologies. The theoretical model is supplemented by a field experiment with actual stakeholders in the climate negotiations and a controlled laboratory experiment.

The project is carried out by Fraunhofer Institute for Systems and Innovation Research ISI (coordination), Karlsruhe Institute of Technology (KIT), and the Kiel Institute for the World Economy (IfW).

CORE is funded by the German Federal Ministry of Education and Research (BMBF, promotional reference: 01LA1127A).
