Petrosea and Yayasan Bakti Barito Expand the Implementation of the Green Guardians Program

Jakarta – On 15 September 2026, PT Petrosea Tbk (IDX:PTRO) officially launched the Green Guardians program in West Jakarta in collaboration with Yayasan Bakti Barito, the philanthropic organization of Barito Pacific Group, as part of its efforts to promote environmental awareness and sustainable practices.

The Green Guardians program is a climate education and school empowerment initiative designed to enhance environmental knowledge and awareness through waste management, energy conservation and the adoption of sustainable practices in schools. This program was initiated by Yayasan Bakti Barito together with several subsidiaries of Barito Pacific Group and has reached nearly 50,000 students in Garut Regency, West Java Province. The collaboration with Petrosea marks the expansion of the Green Guardians program into West Jakarta.

“Petrosea hopes this program will broaden environmental knowledge and awareness while encouraging the younger generation to become drivers of climate action. Schools play an important role in fostering environmental awareness and building sustainable habits from an early age,” said Bita Budiariani, Human Capital & General Services Director of PT Petrosea Tbk.

“In line with Petrosea’s commitment to environmental education, we believe that the participatory approach of the Green Guardians program can encourage more schools in West Jakarta to meet the Adiwiyata criteria and achieve Adiwiyata School status,” said Dian A. Purbasari, Director of Yayasan Bakti Barito.

The Green Guardians program will be implemented in 10 schools in Palmerah District, West Jakarta, targeting approximately 2,000 students and 150 teachers and education personnel. Through a participatory and experiential learning approach, the program will support schools in meeting the indicators of the Adiwiyata Program, an Indonesian government initiative that encourages schools to foster an environmentally conscious and sustainable culture. The launch event was attended by officials from the West Jakarta City Government, including the Mayor of West Jakarta, representatives of the West Jakarta Environmental Agency and the West Jakarta Region II Education Agency. The presence of these stakeholders reinforces collaboration in advancing environmental education and sustainable practices in schools.

“For Petrosea, sustainability is not only reflected in responsible operations, but also in long- term investment in education and raising environmental awareness among the younger generation. Through this collaboration, we hope to help lay the foundation for sustainable behaviors from an early age and create a positive impact that continues to grow within schools and the broader community,” said Meinar Kusumastuti, Legal & Communications Director of PT Petrosea Tbk.

Petrosea continues to strengthen operational excellence through various initiatives aimed at enhancing operational productivity, optimizing efficiency, advancing technology and digitalization, as well as consistently implementing Occupational Health & Safety (OHS) standards across all operational areas in order to support sustainable business growth.
