International Futures (IFs) is a global integrated assessment model designed to help in thinking strategically and systematically about key global systems (economic, demographic, education, health, environment, technology, domestic governance, infrastructure, agriculture, energy and environment) housed at the Frederick S. Pardee Center for International Futures. Initially created by Barry B. Hughes of the Josef Korbel School of International Studies at the University of Denver in Colorado, the model is free for public use in both its online and downloadable forms. 

The Pardee Center for International Futures has partnered with many organizations to produce forecasts and data analysis. IFs has been utilized in the National Intelligence Council's "Global Trends 2020", "Global Trends 2025", and "Global Trends 2030" report. The International Futures model has also contributed to the United Nations "Human Development Report" and the "Global Environmental Outlook". 

IFs is hosted free for public use by Google Public Data Explorer, the Atlantic Council, and the Institute for Security Studies. 

The model incorporates dynamically linked sub-models. They include: population, economic, agricultural, educational, energy, socio-political, international political, environmental, health, infrastructure and technology. IFs is a unique modeling tool because it endogenizes the impact of such a wide range of global systems for 183 countries. 

The help system that accompanies the software provides an extensive overview of the model structure and computer code used to write the model. IFs has three main functions, all connected to its conceptual treatment of integrated assessment forecasts: data analysis, scenario analysis, and display.
