Does the European Court of Justice induce societal change? The record so far—with a green future in mind

Over the seven decades of its existence, the European Court of Justice (ECJ) has performed well as a conflict-solving institution. From the existing literature, it becomes less clear however to what extent it served as an effective agent for societal change. Obtaining clarity on this issue seems imperative in the current day and age, considering the gargantuan challenges of accelerating climate change and environmental degradation: if the ECJ generally manages to ‘deliver’, at least some further progress could realistically be expected on this front also. The present article conducts an examination reviewing the experiences in the green domain from a comparative perspective, seeking to discern possible patterns and draw common inferences. Thus, it aims to expose how and when judges prove successful in recalibrating the conduct or opinions of real people in actual practice. Those insights may well inform future progress in different fields—the ecological as much as anywhere.
