Operationalising the Twin Transition: From EU Constitutional Principles to National AI Strategies

EU policy documents often present the green and digital transitions as “twinned” and mutually beneficial. However, it is now widely acknowledged that new technologies, such as AI, have significant environmental costs. This awareness has induced the EU to recalibrate its approach to the twin transition and prompted the elaboration of new soft-law principles of digital sustainability, an early form of “eco-digital constitutionalism” at EU level. This paper examines the national AI strategies of the twenty-seven Member States to assess the extent to which this revised approach of the EU is reflected at the national level. Our analysis reveals that the strategies in question often differ starkly in the manner in which they prioritise the various matters that pertain to the intersection of environment and AI. We argue that these inconsistencies, which are rooted in different attitudes to the economics of innovation, cannot be solved fully through soft-law harmonisation.
