Standards developed by standard-setting organisations (SSOs) – sometimes labelled private rulemaking – are part of larger practices of governance in most societies yet are underinvestigated from a policy process perspective. Utilising and developing the multiple streams approach (MSA), this article investigates a policy process moving between government and the SSO Standards Norway (SN). The study finds standardisation by SSOs to be an ambiguous institutional arrangement. Strong institutional barriers in theory did not work as such in the case investigated. This article argues that the differentiation between responsibility for process (SN) and content (committee) makes the standardisation process vulnerable. The concept of “institutional deficit” is introduced to describe a potential mismatch between SSOs producing policy in a government-like institution, but where the SSOs are not capable of taking responsibility for policies in a government-like way. This article finds the adjusted MSA useful in this potentially least likely case.

The literature on carbon pricing offers competing explanations for the introduction of carbon taxation. This article contributes to the field by highlighting the interaction of dynamic political factors and external pressures in explaining the timing of the adoption of carbon taxes. Focusing on the second wave of European countries, the study combines the multiple streams framework with qualitative comparative analysis to identify conditions favourable to the introduction of carbon taxes. Additional case studies on Ireland and Portugal serve to illuminate the reform process, especially the role of policy entrepreneurs. This approach yields three insights. First, fiscal crises provide political actors with an opportunity to raise environmental taxes. Second, the introduction of carbon taxation is most likely when push and pull factors come together, i.e. when high problem pressure coincides with governments receptive to environmental issues. Finally, the prospects of “green” policy entrepreneurs are strongly determined by their standing within the government.
