Building momentum for a ‘policy turn’ in sustainability transitions: Lessons from Canada to consolidate strengths and bridge science-policy divides

• The field of sustainability transitions is poised for a ‘policy turn’. • The field would do well to consolidate its strengths and address science-policy divides. • Strengths include defining the problem in terms of systems, driving at systems change, and proposing tuned governance solutions. • Divides relate to institutional embeddedness, connections between communities of research and practice, and an emphasis on theory versus actionable knowledge. Policymaking communities across a wide breadth of contexts are increasingly turning to the field of sustainability transitions to help inform the societal response to critical sustainability crises. Building on a legacy of science-policy affinity and after nearly a decade of rising policy engagement, the field is now poised to build momentum for a ‘policy turn’. However, to make more rapid progress in this regard, the field would do well to consolidate its strengths and address pressing science-policy divides. Based on practical experience engaging with policymakers and taking part in the climate policy process at the federal level in Canada, this policy brief offers reflections on what these strengths are and how to improve policy resonance going forward.
