Development of a National Integrated Assessment Model (IAM) for Energy and Land Use in Angola using the MESSAGE Framework

This study proposes an Integrated Assessment Model (IAM) for Angola, aiming to support technological, economic, energy, and environmental policies through a multisectoral analysis of the productive sectors, transportation, energy, waste, agriculture, and land use. Based on the BLUES and COFFEE models and implemented using the MESSAGE framework, the IAM adopts a bottom-up approach with partial equilibrium and a time horizon extending to 2060. Considering five regions of Angola, the model aligns the country’s Nationally Determined Contributions (NDCs) with the Paris Agreement, promoting low-carbon strategies, reforestation, and CO2 capture, thereby contributing to the decarbonization and sustainability of the energy sector.
