Background and objective: Marine plastic waste is a pressing environmental issue that requires coordinated efforts across various stakeholders to mitigate its impacts effectively. This research examines the multi-stakeholder governance approach towards reducing marine plastic waste in Hoi An coastal city, Vietnam. The study explores the roles and interactions of key stakeholders, including government agencies, local communities, businessmen, scientists, and international agencies, in addressing marine plastic pollution.Methods: Through a combination of interviews, policy analysis, and field observations, this research identifies the challenges and opportunities in implementing sustainable waste management practices. A mixed-methods approach study was conducted and collected data from August 2022 to February 2023, June 2023 to September 2023 and July-August 2024. Two hundred and three random online survey samples were collected. Additionally, forty in-depth interviews were conducted with government officers, businesspeople, researchers, and international agency representatives and each interview lasted for about one hour. The research used both purposive and snowball sampling to maximise the breadth of actors’ perspectives.Results: The research found that effective mechanisms and collaborative governance among diverse stakeholders such as government officials, businesses, communities, international organizations, and scientists are crucial for significantly reducing marine plastic waste. It also underscores the importance of community engagement in preventing plastic waste from entering the ocean and highlights the role of market-driven forces in plastic waste mitigation. Furthermore, the findings emphasize the need to expand scientific and international support to achieve the ultimate goal of reducing marine plastic waste.Conclusion: This study offers insights into best practices and policy recommendations that can be applied to other coastal regions facing similar environmental challenges. By fostering a collective responsibility approach, Hoi An can serve as a model for other coastal cities in Vietnam and beyond in their efforts to combat marine plastic pollution.
