Action-based environmental education plays a crucial role in achieving the Sustainable Development Goals (SDGs) and addressing the global climate crisis. In Indonesia, although environmental awareness is relatively high, it does not consistently translate into concrete and sustainable action, particularly among youth. This community engagement initiative explores the implementation of the Global Youth Network (GYN) Program, a collaborative initiative between Good Neighbors International and Gugah Nurani Indonesia. The initiative aims to assess the impact of the GYN Program in enhancing students’ knowledge, attitudes, and behaviors related to environmental sustainability. A qualitative approach was employed, utilizing participant observation, in-depth interviews, and document analysis. The activities involved five student participants and six facilitators engaged in the program. The findings indicate that the GYN Program effectively promotes global environmental awareness and strengthens students’ capacity for meaningful action through activities such as SDGs education, environmental campaigns, tree planting, composting initiatives, and participation in international forums. Despite challenges including language barriers and time constraints, the program significantly empowers students to take initiative and actively engage in environmental solutions at both local and global levels. The study highlights the potential of collaborative, action-oriented environmental education programs in fostering youth leadership and sustainability engagement.
