<p>The contribution focuses on the role of cities in the implementation of the so-called Green Deal, the ambitious program proposed by the European Commission, in accordance with the objectives set by the Paris Agreements, to implement the use of clean energy resources, favour the circular economy, restore biodiversity and reduce pollution. The Plan, which for the seven-year period 2021-2027 has a budget of economic resources of 100 billion Euro, aims to involve in transcalar perspective all territorial and administrative levels of the Member States and thus contribute to the achievement, in 2050, of climate neutrality. The main objective of the work is then to concentrate, with descriptive intent, on the policies that, in Italy, are being activated at local level in coherence with the European perspectives. In particular, reference will be made to the initiatives proposed and sponsored in Italy by the Committee of the Regions of which a critical overview is proposed. A further reflection will be dedicated to how digital innovation is called to support the macro-policies of energy transition in the EU.</p>
