Climate change mitigation pathways can differ strongly from one to else other, depending on the policy design, technological development or the established climate objectives. Integrated assessment models are able to project countless different climate change mitigation scenarios, allowing to compare the effects that each scenario has on other aspects, such as health, land use, energy security, inequality etc. Moreover, connecting these kind of models with additional tools increases the range of scenario implications that can be studied. In this seminar, we introduce the Global Change Assessment Model (GCAM) and other tools that can be connected to this model, such as the air quality emulator TM5-FASST.
