Our Purpose

The Joint Program on the Science and Policy of Global Change is MIT’s response to the research, analysis and communication challenges of global environmental change. We combine scientific research with policy analysis to provide independent, integrative assessments of the impacts of global change and how best to respond.


At the Joint Program, our integrated team of natural and social scientists studies the interactions among human and Earth systems to provide a sound foundation of scientific knowledge to aid decision-makers in confronting future food, energy, water, climate, air pollution and other interwoven challenges.


We accomplish this mission through:

  • Quantitative analyses of global changes and their social and environmental implications, achieved by employing and constantly improving an Integrated Global System Modeling (IGSM) framework
  • Independent assessments of potential responses to global risks through mitigation and adaptation measures
  • Outreach efforts to analysis groups, policymaking communities and the public
  • Cultivating a new generation of researchers with the skills to tackle complex global challenges in the future


Our continuing goal is to provide decision-makers, both public and private, with information about the risks associated with the impacts of global change. We communicate this information through publications, workshops, congressional testimony, invited talks and conference presentations around the world. We also frequently interact with media outlets, museums, schools, government organizations and our local community.
