of 'neoliberal' power structures). By contrast, transitions theory is strongly informed by the knowledge on innovation dynamics as gathered in Science & Technology Studies, sociology, institutional theory, reflexive governance, and innovation studies. As became especially clear in the discussion of the underlying governance philosophy (section 3), all of the transitions-theoretical innovation frameworks are frontally addressing the basic characteristic of innovation -uncertainty. Transitions literature, following van de Ven et al. (2000), commonly speaks of (sustainable) innovation journeys. It is along this same sensitivity to innovation dynamics and uncertainty that transitions theory seems well equipped to deal with the ambiguous transport innovation challenges of 'exnovation' and 'responsible stagnation' (section 5).
