<p>Sustainability transitions require changing many behaviours
embedded in production and consumption systems. Simultaneously, behavioural
public policy is now a significant site of research-policy translation
globally. Links between behaviour and system change are underdeveloped in both
fields. Systematic review of current transitions literature found ~4% of papers
focused on behaviour. Two prominent perspectives on behaviour (labelled:
‘everyday’ and ‘strategic’) are critical of a focus on individuals,
preferencing broader analysis. Two additional perspectives were identified -
‘automatic’ and ‘reflective’ - which highlight immediate and local influences
on behaviour but underemphasise context. All four perspectives on behaviour
draw on different conceptualisations, causality, methods and disciplinary
foundations, and yet all have value and application to transitions. We argue
that a complimentary and flexible approach to behaviour would benefit the field,
considering the diversity of phases, scales and contexts of sustainability
transitions. Transitions’ own behavioural perspectives could also help address
behavioural public policy’s challenges.</p>
