These initiatives have served as reference models for national replication and policy scaling.

In the realm of energy advocacy, Unggung actively contributes to shaping national and subnational energy conservation and climate policies. He has supported ministries such as MEMR, Bappenas, and MoEF in drafting key regulations, developing technical guidelines, and strengthening institutional capacity. He frequently serves as a trainer, speaker, and facilitator in multi-stakeholder forums, reinforcing his role as a connector across government, industry, and civil society.

His work is backed by deep collaboration with international development partners such as UNDP, USAID, GIZ, UK-PACT, and DANIDA. His contributions have supported the integration of sustainability, inclusivity, and data-driven approaches into Indonesia’s energy planning and climate governance.

Certified as an Energy Auditor, Competency Assessor, and Climate Reality Leader, Unggung continues to play a key role in mainstreaming climate-responsive practices throughout Indonesia’s energy landscape.
