Nature-based Solutions (NbS) have gained global attention for their transformative potential to simultaneously address biodiversity loss, climate change, and human well-being. However, there are concerns that dominant framings reinforce vested interests, marginalise alternative perspectives, and lead to persistent patterns of inequality and injustice. While participatory governance of NbS is widely acclaimed to support more equitable and ‘just’ outcomes, it is unclear to what extent the necessary changes can occur within dominant framings and approaches. To address this gap, this paper foregrounds the messy, contested, and discontinuous politics of sustainability transformations to explore how different framings influence the transformative potential of NbS.
