International Institute for Applied Systems Analysis


In October 1972 representatives of the Soviet Union, United States, and 10 other countries from the Eastern and Western blocs met in London to sign the charter establishing the International Institute for Applied Systems Analysis (IIASA). It was the culmination of six years’ effort by US President Lyndon Johnson and USSR Premier Alexey Kosygin, and marked the beginning of a remarkable project to use scientific cooperation to build bridges across the Cold War divide and to confront growing global problems on an international scale.
In the 1990s, the Institute broadened its mandate to achieve a greater global focus. Today IIASA brings together a wide range of scientific skills to provide science-based insights into critical policy issues in international and national debates on global change, with three central research focuses.
IIASA has 22 National Member Organizations (NMOs). NMO countries account for over half the world’s population (63%) and production (68%). They include not only the world’s four largest economies, but also some of fastest-growing economies in the developing world.


IIASA provides insights and guidance to policymakers worldwide by finding solutions to global and universal problems through applied systems analysis in order to improve human and social well-being and to protect the environment.
