IIASA (Internationale Institute for Applied Systems Analysis) is an independent, international research institute with National Member Organizations in Africa, the Americas, Asia, and Europe. Through its research programs and initiatives, the institute conducts policy-oriented research into issues that are too large or complex to be solved by a single country or academic discipline. The results of IIASA’s research and expertise are made available to policymakers in countries around the world to help them produce effective, science-based policies that will enable them to face these challenges. IIASA’s role in MICAT is centred on the framework development of the empirical basis of the project’s environmental impacts.
