Energy dependence and rising pollution from the energy sector have compelled states to re-evaluate their energy policies and legal frameworks in favour of sustainable energy development. In this context, energy transition emerges as a strategy to achieve global climate goals while ensuring energy security. However, making the energy transition a “just transition” presents numerous challenges. These challenges are growing as innovation in the energy sector accelerates, with digitalisation presented as a tool to drive the energy transition and optimise current energy systems. This trend has been integrated into the EU’s policy objectives and regulated by the EU’s legal framework. However, this political decision has sparked ethical and legal debates about the digital transformation of the EU energy sector, particularly regarding energy justice. By analysing instruments in the EU’s policy and legal framework, this paper addresses the intersection of the twin transitions through the lens of energy justice. Therefore, this study assesses the EU policy and legal framework of twin transitions from an energy justice perspective. The geographical scope of this research covered the EU. The methodology includes doctrinal legal research. The conclusions of this research encompass an assessment of selected EU policy and legal instruments applicable to the twin transitions.
