Institution COPPE/UFRJ (Cenergia), Brazil,
Solution concept General equilibrium (closed economy)
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.

COFFEE and TEA models simulate emissions from long-lived GHGs (CO2, CH4, N2O). CO2 emissions from fuel combustion are calculated based on energy sources. CO2 resulting from land-use changes is endogenously calculated as a consequence of the land use (taking difference of land use from previous year). Non-CO2 emissions, CH4, and N2O emissions are basically associated with each sector's activity level. GWP100 (AR5).
