Population and GDP are main drivers of future energy demand and, thus, GHG emissions in REMIND. We base population and GDP inputs on the Shared Socio-economic Pathway (SSP) scenarios (KC and Lutz 2014; Dellink et al. 2015). By default, we apply the population projections (both total population as well as working age population) from IIASA and the GDP scenarios from the OECD ([https://secure.iiasa.ac.at/web-apps/ene/SspDb/dsd?Action=htmlpage&page=about https://secure.iiasa.ac.at/web-apps/ene/SspDb/dsd?Action=htmlpage&page=about]). Individual projections are available for each of the five SSP scenarios. By default, we use SSP2 scenario data. To calibrate GDP, which is endogenous result of the growth engine in REMIND, we calibrate labor productivity parameters in an iterative procedure so as to reproduce the OECD's GDP reference scenarios. Within REMIND, GDP is measured in market exchange rates (MER).
Population is an exogenous input for REMIND-MAgPIE (see description under Socio-economic drivers). It enters the model in just two forms: total population and working age population. While the welfare measuring is based on total population, the working age population is used as labor input in the macroeconomic production function. The exogenous labor input affects the dynamics of other macroeconomic production factors (capital, energy) since the model seeks an optimal allocation of production factors.
Total population is also used for generating energy demand scenarios that are mainly based on assumptions about the development of per capita demand on different energy types (see description under Energy demand)

Population is an exogenous input for REMIND-MAgPIE (see description under Socio-economic drivers). It enters the model in just two forms: total population and working age population. While the welfare measuring is based on total population, the working age population is used as labor input in the macroeconomic production function. The exogenous labor input affects the dynamics of other macroeconomic production factors (capital, energy) since the model seeks an optimal allocation of production factors. Total population is also used for generating energy demand scenarios that are mainly based on assumptions about the development of per capita demand on different energy types (see description under Energy demand)
