## 5 Overview of Policy, Technology, and Stakeholder Collaboration
### Stakeholder Collaboration Overview
Voluntary sustainability efforts and customer engagement further strengthen green adoption. In Europe, such collaboration facilitates policy-driven transitions, whereas Asia is increasingly leveraging cross-sector alliances to address expanding trade networks. Extending the Green Corridor Concept: Clarifying Technological Innovations, Policy Reforms, and Stakeholder Collaborations  
Green shipping corridors are in the initial phase of a four-stage implementation process, where key stakeholders collaborate to establish a shared vision and identify optimal trade routes for zero-emission shipping [11]. In accordance with [11], the stated phase consists of the following four developmental elements: (1) Stakeholder Workshops; (2) Country-Level Assessment; (2) Formation of Core Stakeholder Group; and (4) Governance Agreed. Figure 5 depicts the four developmental elements of the GSC imitation phase [11]. Figure 5 represents the four developmental elements, briefly discussed as follows [11]. Stakeholder workshops are conducted to exchange ideas, define objectives, and set the foundation for green corridor projects between maritime companies, policymakers, and community leaders. Country-level assessments review national regulations and economic conditions, ensuring that strategic decisions are grounded in real-world policy contexts. Once key insights emerge, a core stakeholder group is formed, representing vital sectors and governmental bodies to spearhead planning and execution. Finally, all parties agree on a clear governance structure, establishing transparent roles, decision-making protocols, and organizational frameworks. This cohesive approach helps to maintain alignment and momentum as green corridor initiatives advance. Stakeholder Workshops serve as a foundational mechanism for uniting maritime companies, policymakers, and community leaders to exchange ideas and define shared objectives. This aligns with the broader policy impetus emphasizing coordinated governance structures and robust institutional frameworks [46; 49]. By harnessing diverse perspectives, workshops create an environment conducive to addressing challenges identified in studies, including the need for technology roadmaps and strategic investment tools. Once these preliminary insights are articulated, the Country-Level Assessment phase scrutinizes national regulations, economic factors, and market conditions [55]. This systematic evaluation ensures that policy recommendations, such as zero-carbon fuel mandates or flexible investment incentives, are matched with actual operational constraints. Together, these activities

Hence, they serve as essential precursors for corridor development. After deriving critical insights from workshops and assessments, the Formation of a Core Stakeholder Group marks the next strategic milestone. This dedicated coalition, typically comprising industry leaders, government officials, and NGOs, coordinates corridor planning and ensures resource alignment across sectors. Reflecting institutional theory's emphasis on regulatory, normative, and market-driven pressures [46], the group promotes proactive engagement and fosters cross-functional collaboration. Its tasks include clarifying roles, mobilizing investments for advanced technologies, and drafting guidelines for zero-carbon fuel adoption. Once membership and objectives are finalized, Governance Agreed outlines the corridor's formal decision-making protocols and accountability structures. This process, supported by flexible decision-making tools [48; 54], mitigates risks and encourages iterative policy refinement. Consequently, corridor initiatives can progress with stable oversight and concerted industry compliance.
