Written with clarity and rigor, the outlook will be of interest to policymakers, scholars, and practitioners seeking to understand the dynamics of Europe's green transition. It invites readers to consider the balance between national priorities and collective European objectives, offering valuable insights into how commitments translate into action-and how public investment can be a decisive lever for change.
