COFFEE-TEA documentation consists of a referencecard and detailed model documentation

Model scope and methods

Model documentation: Model scope and methods - COFFEE-TEA

Objective

The models were developed at COPPE/UFRJ, Brazil, for assessing climate, land, energy and environmental policies, providing relevant information to experts and decision-makers about the possible development strategies and repercussions of long term climate scenarios.

Concept

The models can run scenarios as a stand-alone application or linked through a soft-link process.

Solution method

The COFFEE model is solved through Linear Programming (LP). The TEA model is formulated as a mixed complementary problem (MCP) and is solved through Mathematical Programming System for General Equilibrium -- MPSGE within GAMS using the PATH solver.
