This paper argues that CU modernisation, in line with the changing imperatives brought along with the Green Deal, provides a concrete step in preparing the ground for a positive agenda, better collaboration and potentially deeper integration in Turkey-EU relations amid the drastic overhaul of the global economic and political order. Indeed, the EU Green Deal, initiated in 2019 and solidified in 2021, has rendered the basis provided by the initial proposals regarding both CU modernisation and the “Positive Agenda” inadequate and imbalanced. We believe that updating the CU in line with the Green Deal will pave the way for much-needed stability, trust, and a non-binary/positive-sum perspective of interest for improved communication and cooperation.
