Capturing key energy and emission trends in CGE models: Assessment of status and remaining challenges

Many of the current modelling and baseline procedures in Computable General Equilibrium (CGE) analysis are motivated by the need to understand potential greenhouse gas (GHG) emission trajectories and possible transition pathways to a decarbonised future. Limiting global warming to below 2°C, or even 1.5°C, in line with the goals in the Paris Agreement will require substantial technological and behavioural transformations (IPCC, 2018). Mid-Century strategies are to be prepared and submitted by all Parties by 2020. The long time horizon of the climate change impacts and technological change makes long-term projections and scenario studies of energy and emissions evolvements necessary.
