The MENA phase model for sustainable transformation has been applied to ten countries of the region, namely: Algeria, Egypt, Iraq, Israel, Jordan, Lebanon, Morocco, Palestine, Tunisia, and Yemen. The current state of development in each country was assessed and analysed against the phase model. Expert interviews were conducted to gain insights to specify the previously defined abstract components of the model, with further steps for the energy transition (based on the steps of the phase model) proposed. The application of the model is based on findings from previous studies and projects conducted in the MENA region, with specific case study data being collected and analysed by local partners specialized in the field at each country.
