The Integrated Global System Model (IGSM) is an Integrated Assessment Model (IAM) developed by the Massachusetts Institute of Technology (MIT) Joint Program on the Science and Policy of Global Change.
[4] The IGSM has been referenced by the United States Environmental Protection Agency[6] and the Intergovernmental Panel on Climate Change.
[7][8] The IGSM has also been referenced in academic literature on climate systems, human activity, and policy implications.
[12] The strategy for investigating the impacts of climate change on Earth’s physical, biological and human resources and links to their socio-economic consequences in the MIT IGSM is discussed in an article published in Climatic Change in 2013.
[13] A demonstration of the IGSM capabilities for multi-sectoral assessment of climate impacts under a range of consistent and integrated economic and climate scenarios that are responsive to new policies and business expectations was published in Nature Communications in 2018.
