WP 2020-77 The IMACLIM-SAU model Version 1.0

Salaheddine Soummane, Frédéric Ghersi


The IMACLIM model is an economy-wide model representing the comprehensive supply and demand of factors, goods and services, with the specific purpose of articulating with a consistent representation of energy systems to provide consistent ‘economy-energy-environment’ (3E) trajectories (Hourcade et al., 2006; Ghersi and Hourcade, 2006). IMACLIM is part of a tradition of ‘hybrid’ energy/economy exercises, carried out at the Centre International de Recherche sur l’Environnement et le Développement (CIRED) to contribute to the economics of climate policies. It exists in a global multi-regional version (Sassi et al., 2010) and in country-specific versions. Developed variants include adaptations to France (Hourcade and Ghersi, 2000; Combet, 2013; Le Treut, 2017; De Lauretis, 2017), South Africa (Schers et al., 2015), Brazil (Lefèvre, 2016) and India (Gupta and Ghersi, 2019; Gupta et al., 2019a; 2019b). IMACLIM-SAU results from ongoing efforts to adapt the IMACLIM model to an additional set of countries via a common modelling platform (Le Treut, 2017).1 Reflecting the IMACLIM paradigm although with some adaptation to the particulars of Saudi macroeconomics, IMACLIM-SAU deviates from the computable general equilibrium (CGE) standard by four features.
