The integration of sustainability into project management practices has gained significant traction in academic discourse and the professional environment (Avery & Bergsteiner, 2011; Contreras-Medina et al., 2021; Silvius, 2016). In particular, knowledge intensive organizations, marked by a reliance on specialized expertise and continuous innovation, operate in contexts where traditional project management paradigms are increasingly insufficient (Nieto-Rodriguez A., 2021). In such contexts, the evolution of managerial competences is critical to reconcile the pursuit of sustainability with the conventional constraints of project delivery. The complexity inherent in sustainable project management necessitates a reconfiguration of competences, moving beyond technical proficiency to encompass systems thinking, ethical sensitivity, and knowledge-driven adaptability. Project managers must be equipped to navigate tensions arising from competing temporalities, organizational resistance, and reduced control over external sustainability variables. In this regard, knowledge management plays a foundational role. Furthermore, this demands advanced coordination capabilities due to the high degree of task interdependence and the necessity for cross-functional collaboration. While project time constraints often accelerate execution, they may simultaneously limit opportunities for reflective learning and the deep exchange of domain-specific expertise (Suarez & Montes, 2020). To address this, project managers must develop competences related to facilitating knowledge integration through mechanisms such as collaborative planning, structured interaction, and socio-technical knowledge platforms (Bruns, 2013). Examining the interplay between evolving competences and intelligent knowledge practices offers critical insights into how sustainability can be operationalized in project contexts. Such inquiry contributes to a deeper understanding of organizational transformation and the development of sustainable capabilities in knowledge-driven environments (Lundin et al., 2015). We welcome submissions that explore how sustainability is being integrated into project management within knowledge-intensive organizations, particularly through the development of managerial competences and knowledge practices. Topics of interest include, but are not limited to: the reconfiguration of project manager competences; the emergent competences: systems thinking, ethical sensitivity, stakeholder dialogue, adaptability, and reflexivity; knowledge management practices that support sustainability; mechanisms for coordinating across functional, disciplinary, and temporal boundaries to foster sustainable project outcomes; the role of organizational culture, resistance, and external pressures in shaping sustainability integration.
