The eclac-Climate Impacts Assessment Model (CIAM) is a modelling platform that has been created to assess the economic consequences of climate change in the Caribbean. The model can be freely accessed, downloaded and even modified. The version available is a full-fledged model which can readily be used to conduct simulation exercises. This paper provides a general description of the model and an illustrative simulation exercise. Our results from this exercise highlight the fact that the Caribbean is a highly vulnerable region where climate change is expected to generate sizeable and negative economic consequences.
