Cross-sector collaboration, nonprofit readiness, and sustainability transitions

• Bridging sustainability transitions literature with public and nonprofit management research. • Awareness, capacity and actions are central to nonprofit readiness for sustainability efforts. • Government support can either facilitate or constrain the sustainability efforts of nonprofit organizations. • Nonprofits in Singapore are partially ready to participate in collaborations for sustainability transitions. Cross-sector collaborations—partnerships between organizations from multiple sectors (e.g., the public and nonprofit and voluntary sectors)—are key to sustainability transitions yet remain understudied. In this study, we assess the readiness of nonprofit organizations for engaging in collaborative sustainability efforts. We develop and empirically validate a theoretical framework focusing on three key dimensions of readiness: awareness, capacity, and actions. Using an important yet less-studied empirical context of Singapore, and informed by evidence from thirty-nine in-depth interviews, our findings reveal that nonprofits in Singapore are generally aware of sustainability transition challenges and opportunities and possess important capacities such as organizational agility and digital adaptability. However, proactive actions remain limited, partially due to the predominant role of the state in sustainability action. Our research contributes to understanding the role of nonprofit and voluntary actors in collaborative efforts for sustainability transitions, offering valuable insights for strengthening a collaborative approach to sustainability transitions.
