Is an urban waste-to-energy plant a “green” megaproject? The power of narratives in shaping the city: a Danish case study

The role of communication in shaping cities has increased mainly in the last decades due to its relevance to the policymaking process. Even if the scientific debate regarding the Narrative Policy Framework reveals the importance of policy narratives influencing policy outcomes, the relationship between policy and political narratives has often been overlooked. In this paper, we explore this relationship by analysing the policy process of a megaproject case study involving a waste-to-energy plant in Denmark and the intricate process leading to its realisation. The polysemic concept of Smart Cities initially divides the policy arena between proponents of a pro-growth rhetoric focused on market strategy (advocating for a larger plant to expand market scope) and proponents of a pro-green rhetoric embracing sustainability, questioning the adequacy of the plant’s size (and highlighting potential negative trade-offs of a big plant). We illustrate how implementing policy ideas relies heavily on constructing narratives that political decision-makers use to advocate for specific policies (policy narratives) presented within a broader institutional discourse in the political arena (political narratives). This study assesses how the polysemic nature of policy ideas influences contemporary social institutions’ governance, structure, and operation, posing a challenge for environmental public management in today’s cities.
