Discourses around decline

To accelerate sustainability transitions, policymakers have to set clear targets for the decline and phase-out of unsustainable technologies. As such decisions are contested, many different actor groups engage in the politics and discourse around decline. This chapter compares the debates surrounding coal phase-out in three countries: the UK, Germany and Finland. Despite major differences, e.g. in the relevance of coal for energy supply and jobs, we find many similarities in discourse dynamics, key arguments and the actor groups engaged. Our findings can therefore inform debates about coal and other unsustainable technologies in places where phase-outs are still pending. Our analysis advances the repertoire of comparative studies in transitions research, and shows how the technological innovation systems framework can be mobilized to also explore processes of technology decline.
