Summary: WITCH is an energy-economy-climate model developed by the climate change group at the Fondazione Eni Enrico Mattei (FEEM). The model has been extensively used in the past 3 years for the economic analysis of climate change policies. WITCH is a hybrid top-down economic model with a representation of the energy sector of medium complexity. Two distinguishing features of the WITCH model are the representation of endogenous technological change and the game–theoretic set-up. Technological change is driven by innovation and diffusion processes, both of which feature international spillovers. World countries are grouped in 12 regions which interact with each other in a setting of strategic interdependence. This paper describes the updating of the base year data to 2005 and some new features: the inclusion of non-CO2 greenhouse gases and abatement options, the new specification of low carbon technologies and the inclusion of reducing emissions from deforestation and degradation.

In the model investment costs per kwh decline from $1,906 in 2010 to $1,010 in 2050 to 649 in 2100. CO2 emissions grow at a declining rate from the current 8 GtC to over 23 GtC in 2010. Temperatures rise steadily by 3 degrees centigrade to 2010.
