## 4 Discussion  
This research highlights the crucial link between POE resilience and the successful implementation of green transitions. A key barrier identified is the lack of a comprehensive 'green rates' evaluation methodology. Without such a framework, it is challenging to benchmark progress and develop consistent policies across the port sector. While acknowledging the importance of technological advancements, the study emphasizes that managerial competencies are critical for accelerating green transitions, especially in the conditions where the methodology of green transitions' assessment is not elaborated yet [20; 25]. The study identifies several critical challenges within POEs, including outdated infrastructure, cybersecurity vulnerabilities, and insufficient managerial skills, all of which impede the integration and management of green technologies, as outlined in previous research [19; 21; 23]. These findings align with prior studies that emphasize the pivotal roles of leadership, human resource management, and stakeholder engagement in advancing green transitions [7; 8; 9; 14; 15]. The research identifies several key implications for policymakers, port managers, and stakeholders. POE companies and organizations must invest in training and development programs to equip managers with the skills and knowledge necessary to effectively lead the transition process [10; 14; 30]. Cultivating a workplace environment that encourages innovation, embraces change, and promotes continuous learning is crucial for overcoming resistance to change and promoting the adoption of green practices and transitions [9]. POEs must actively address the technological challenges associated with green transitions, including outdated infrastructure, cybersecurity threats, and the need for ongoing investment in new technologies [11; 16]. Building strong partnerships with stakeholders, including government agencies, industry associations, and environmental organizations, is critical for creating a supportive environment for green transitions. These findings directly confirm the hypothesis that not only technological innovations force green port development, but the newest technological innovations and dynamic management skills can accelerate green transitions in the POE through the implementation of effective managerial interventions detailed previously. This research identifies several avenues for future research. A deeper investigation of the specific challenges and how they impact managerial decision-making could involve examining the specific managerial skills and competencies needed to overcome each technological challenge, as well as the factors that hinder the development of these skills. Further exploration of the specific roles and contributions of stakeholder partnerships could involve identifying the key stakeholders involved in green transitions, their respective roles and responsibilities, and the challenges they face in working together. The study identifies several potential managerial interventions for accelerating green transitions. Future research could focus on evaluating the effectiveness of these interventions in practice. This could involve conducting case studies of ports that have implemented different managerial interventions and comparing their outcomes. This study acknowledges the limitations of qualitative research methods and limitations arising from its focus on a specific context. Contextual limitations are related to the selection of regions. The Klaipeda port, a mid-sized port in Lithuania, as a national state-owned seaport located in a non-capital city, influenced the structure of the focus group interview participants according to the strategies of the sampling methodology, ensuring the validity and reliability of research. This choice, while providing valuable insights, restricts the generalizability of findings, potentially omitting arguments and facts relevant to larger ports.
