This policy brief identifies some key priorities that the new European Commission will need to focus on, which tackle both the progress and acceleration of energy transition processes in Southern Mediterranean countries and a pathway of progressive integration within the two shores of the Mediterranean. As such, the operative and financial support to Southern Mediterranean countries in the all-round development and implementation of their national long-term energy pathways will need to go hand in hand with increasing cooperation in the area of adaptation as a key element of the external dimension of the EU Green Deal and the Global Gateway.
