GTSP research is organized around five intersecting and overlapping activities.
Core Model development: Although GTSP research relies on several modeling tools, the Global Change Assessment Model (GCAM) is the research work horse of the GTSP. GCAM is a means to capture and integrate knowledge in all GTSP research activities. Maintaining, improving, and exercising the GCAM is a central GTSP activity.
Technology Analysis: Research on the potential evolution of existing and new technologies is at the core of all GTSP research, and is used to enhance the representations of technology in GCAM and other modeling tools.
Regional Analysis: Strategies to address climate change are strongly influenced by regional capabilities, resources, and institutions. Regional research explores these varying capabilities, resources, and institutions.
Technology and Institutions: Technology deployment takes place not only in a physical, but also a social and institutional context. Research on institutions informs the environment in which countries take action on climate change in which technologies are deployed.
Scenarios: Scenarios recognize the inherent uncertainty in projecting the future; they serve as a means to create specific manifestations of the interactions between and evolution of the key forces that determine the nature of technology strategies.
