The Mercator Research Institute on Global Commons and Climate Change (MCC) is a scientific think tank that assesses strategies for sustainable management of the commons, including natural commons such as land and the atmosphere, as well as social commons such as public infrastructure. Seven working groups conduct research on the topics of economic growth and development, resource management, cities and infrastructure, governance and policy assessments. A special focus is on scientific policy advice: The MCC aims to identify synergies and trade-off between different policy objectives in the context of climate change and sustainable development, and to provide the basis for public debate and policy making. For 2014 the MCC, an affiliated institute of TU Berlin, was designated by the International Center for Climate Governance (ICCG) as the second best scientific think tank in the field of climate change. The MCC was jointly founded by the Mercator Foundation and the Potsdam Institute for Climate Impact Research (PIK).
