Digital technologies and public policies are fundamental for cities to define their urban greening strategies, and the main goal of this research is to identify in the literature and official documents the applied digital technologies and the public policies dimensions implemented at the national level by the member states to promote urban greening. The methodology used is a Systematic Literature Review (based on international studies), a Delphi study with experts, and a Policy Analysis, to understand how the Portuguese government has implemented policies and which are the main applied technologies to urban greening. The main findings are regarding (i) the focus on the interaction of actors in policymaking. (ii) Interpretive approaches examine the application of technologies in urban greening problems; and (iii) how policies reflect the social construction of 'problems'.
