Following the Paris Agreement, investing in renewable energy production at sea is perceived as a promising development. In addition, food security challenges place increased focus on utilizing seas and oceans while biodiversity and ecosystem integrity must be safeguarded. In the North Sea, these three challenges are combined by the Dutch government in a deliberative governance agreement, involving key stakeholders, aimed at establishing a marine spatial allocation strategy. This paper outlines the development and first outcomes of this agreement. Using concepts of sustainability transitions and deliberative governance, we examined the role of the Dutch government in creating sustainability solutions through cross-sectoral participation processes. Based on our results, we argue that only the government can bring together parties that do not actively seek cooperation, like fisheries organizations and wind farm developers. This is in line with the government’s role to ensure compliance with international and national agreements, while also representing local (national) stakes. By opening up a discussion between parties that in the past were competing for marine space, the Dutch government has managed to make progress in obtaining transition goals. One of these transitions is the transition of the governance system itself, moving towards a more egalitarian style of policy making.
