The constrained influence of discourses: the case of Norwegian climate policy

Norwegian climate policy has been marked by several shifts with regard to adopted targets and measures to reduce emissions of greenhouse gases. Three knowledge-based discourses – respectively a tax discourse, a quota discourse and a technology discourse – have been influential throughout. By tracing the development of Norwegian climate policy from 1989 until 2008, it is shown, however, that while significant in early phases of policymaking, the discourses lose influence in the phase when policy solutions are designed and implemented. Those ideas and ambitions that characterise the ruling discourses in Norwegian climate policy are not necessarily materialised in actual policy.
