ENTo explore what roles incumbent actors take in sustainability transitions, this paper investigates the current situation in the scientific literature, which reveals a shift from opponents to promoters and the case of a post-Soviet transitioning economy that is exemplified by examining five sustainability-oriented incumbent actors in Lithuania. A single case study design is selected as a methodological approach, illustrated by empirical data from interviews and secondary sources (corporate websites and sustainability reports). These examples provide insights on the initiatives the organisations that are already interested in sustainability take to promote sustainability ideas and be active members of the transition themselves, supporting the contemporary view of incumbents as agents of sustainable transitions.
