Indonesia is one of the largest contributors of plastic waste entering the oceans globally. UNEP data indicate that Indonesia generates approximately 3.2 million tons of mismanaged plastic waste annually, with around 1.29 million tons ending up in the ocean. Recognizing this situation, Indonesia has committed to reducing marine plastic waste by 70% by 2025 through a range of policies, programs, and multi-stakeholder collaborations. This commitment is reflected, among others, in Presidential Regulation No. 83 of 2018 on Marine Debris Management and the National Action Plan on Marine Debris Management (RAN-PSL) 2018–2025. In support of these efforts, PATTIRO, together with the Asian Development Bank (ADB) and the Directorate General of Regional Development of the Ministry of Home Affairs (SUPD IV), is encouraging at least ten local governments to adopt and implement the Gender Action Budget (GAB) in waste management services to strengthen gender mainstreaming and enhance women’s participation in more effective and inclusive waste management.
