MEDEAS-World model calibration for the study of the energy transition

MEDEAS (Modelling the Energy Development under Environmental And Socioeconomic constraint) World is a new global-aggregated energy-economy-environmental model, which runs from 1995 to 2050. In this work, the MEDEAS world model is tested in order to reproduce the IPCC (International Panel on Climate Change) GHG (Green House Gases) emission pathways consistent with 2 °C Global Warming. A parameter optimisation of the MEDEAS model, related to different scenarios until 2050, is achieved. Moreover, a sensitivity analysis on the parameters that directly influence the emission curves focusing on the annual growth of the RES (Renewable Energy Sources), GDP (Gross Domestic Product) and annual population growth, is provided. From such an analysis, it has been possible to infer the large impact of GDP on the emission scenarios.
