COALMOD-World is a model of the international steam coal market that can be readily used to explore implications of climate policies, but also to analyze market structure or to investigate issue of supply security. It features a detailed representation of both domestic and international steam coal supply, based on endogenously calculated Cost, Insurance, Fright (CIF) costs, and prices that take into account additional rents. It features endogenous investment into production, land transport, and export capacity, as well as an endogenous mechanism assessing production cost increase due to resource depletion.

The model is implemented in the General Algebraic Modeling System (GAMS). Running the model thus requires a GAMS system, a MCP solver, and respective licenses. We use the commercial solver PATH.
