This study examines policy adjustments toward a green economy in customary areas of Papua Province, Indonesia, after its division in 2022. It utilizes qualitative methods with secondary data sources from government policy documents. The analysis focuses on several key aspects: policy adjustments with restrictions on mainstreaming, stakeholder analysis, communication strategy, financing and budgeting, and monitoring and evaluation. The implementation of the green growth master plan in Papua Province is a significant initiative, setting a long-term development direction. The territorial division serves as a catalyst for accelerating the gradual transformation of resources and achieving sustainable community welfare. However, policy adjustments are necessary to address challenges in mainstreaming, stakeholder engagement, communication, financing, and monitoring. The implications include sustainable land use and allocation, integrated village development with natural resource management, a robust green commodity value chain, and innovative funding mechanisms for environmental services. These adjustments must consider boundary priorities, stakeholder sensitivity, tiered informal communication, stakeholder involvement in costs and budgets, and regular monitoring and evaluation processes.
