## 5 Overview of Policy, Technology, and Stakeholder Collaboration
### Policy Overview
Such comprehensive approaches can provide a safer foundation regarding the effective transition toward sustainable maritime operations, significantly reducing environmental impacts and promoting industry-wide adherence to green shipping practices. Table 8 categorizes a list of policy recommendations regarding GSC development within the initiation phase. \begin{table}
\begin{tabular}{c c c} \hline \hline
**Policy Name** & **Policy Definition** & **References** \\ \hline \multirow{6}{*}{Institutional Frameworks for GSP Adoption} & Policy frameworks leveraging coercive & \\  & regulatory measures, normative industry & \\  & standards, and mimetic market-driven & \\  & pressures to ensure the adoption of green & \\  & shipping practices (GSPs), including & \\  & eco-friendly equipment and & \\  & voyage optimization. & \\ \hline \multirow{6}{*}{Stakeholder-Driven Sustainable Policy} & Policies designed to engage stakeholders, & \\  & utilizing stakeholder theory, planned & \\  & behavior theory, and resource & \\  & dependence theory to encourage & \\  & sustainable behavior in shipping firms & \\  & through direct and indirect influences. & \\ \hline \multirow{6}{*}{Quantitative Policy Impact Assessments} & Policies necessitating quantitative & \\  & assessments of how green initiatives & \\  & influence environmental and economic & \\  & performance, employing interdisciplinary & \\  & methodologies including mathematical & \\  & modeling and scenario analyses. & \\ \hline \multirow{6}{*}{Zero-Carbon Fuel Transition Policies} & Policies promoting adoption of & \\  & alternative marine fuels (especially \\  & hydrogen and ammonia) with incentives & \\  & for infrastructure investments, & \\  & technological maturity, and addressing & \\  & economic feasibility to achieve emission & \\  & reduction targets by 2050. & \\ \hline \multirow{6}{*}{Voluntary Initiative Support Policies} & Economic and regulatory policies & \\  & designed to support and incentivize & \\  & corporate voluntary sustainability & \\  & measures (e.g., electrification and vessel & \\  & retrofitting), overcoming initial & \\  & investment barriers and promoting & \\  & widespread adoption. & \\ \hline \multirow{6}{*}{Collaborative Governance Policies} & Policies that foster integrated operational & \\  & cooperation between ports and shipping & \\  & companies, including optimized berth & \\  & allocation, adjusted sailing speeds, and & \\  & coordinated scheduling for & \\  & emission reductions. & \\ \hline \multirow{6}{*}{Flexible Investment Decision Policies} & Policies employing strategic decision & \\  & support tools (e.g., real options & \\  & analysis—ROA) to address financial and & \\  & market uncertainties in investment & \\  & decisions for sustainable technologies, & \\  & encouraging timely and informed & \\  & investment choices. & \\ \hline \hline \end{tabular}

Table 8: Policy recommendations regarding GSC development within the imitation phase. In accordance with document [11], Europe hosts 21 green shipping corridor (GSC) initiatives, while Asia has 14. European GSCs are largely guided by a mix of public-private and government leadership, whereas Asian corridors see stronger industry (PA)/third-sector drivers. Combining these insights with Table 8's policy recommendations suggests focusing on institutional frameworks and stakeholder-driven policies in Europe, where regulatory alignment and collaborative governance can flourish. In Asia, voluntary initiative support and flexible investment decisions can address diverse market conditions and encourage technology adoption. Both regions benefit from zero-carbon fuel transition policies, emphasizing hydrogen and ammonia, and from robust transnational environmental governance. Coordinated approaches will expedite uptake, ensuring both regions achieve sustainable maritime outcomes.
