GTEM-C

GTEM-C is a hybrid model that combines a core macroeconomic general equilibrium model with a bottom-up module of energy production with engineering details of various energy technologies. The GTEM-C model was developed from the original version of GTEM (Pant, 2007) and has been applied in integrated assessment frameworks for climate policy analysis (Garnaut, 2011; Gunasekara et al., 2008; Harman et al., 2008). The current version of GTEM-C is well documented in Cai et al., (2015) and features detailed accounting for global energy flows that are embedded in traded energy goods and an updated parameterisation and cost structures of different power technologies in the electricity “technology bundle”. GTEM-C has also been used in producing material use projections for the International Resource Panel reports (UNEP, 2017b; UNEP, 2019) and in the peer reviewed literature (Hatfield-Dodds et al., 2017; Schandl et al., 2016).

In this version of the GTEM-C model, 28 regions and 21 production sectors are explicitly represented. The regional and sectoral classifications are documented in Tables S1 and S2 in the supplementary information.
