Indonesia Mandates 5% Bioethanol for Non-Subsidized Gasoline Starting Late 2026 to Accelerate Green Transition

JAKARTA, Investortrust.id — Indonesia is taking a definitive step toward decarbonizing its transport sector by enforcing a nationwide 5% bioethanol blend (E5) for all non-subsidized gasoline, scheduled to take effect in the second half of 2026.

The aggressive timeline marks a major escalation in the country’s biofuel strategy. The Ministry of Energy and Mineral Resources (ESDM) positions this mandate as a critical lever to slash fossil fuel imports and fast-track the national energy transition.

For global energy markets and clean energy investors, Indonesia's shift to mandatory bioethanol introduces a massive new demand center for agricultural commodities. By integrating biofuel into the non-subsidized fuel ecosystem, the government is effectively creating a guaranteed domestic market for local sugar and cassava processors.

This move will heavily impact state-owned energy giant Pertamina and private fuel distributors, forcing a rapid upgrade of storage and logistics infrastructure across Java. Furthermore, it sets a precedent for Southeast Asia’s largest automotive market as it balances traditional combustion engines with a growing push for electrification.

The Roadmap to Implementation

The regulatory framework is already locked in. The policy anchors on the newly minted Minister of ESDM Regulation No. 4/2025, which dictates the operational blueprints of the national bioethanol program.

Eniya Listiani Dewi, the Director General of New Renewable Energy and Energy Conservation (EBTKE) at the Ministry of ESDM, confirmed that the regulatory mandate is finalized and awaiting imminent official publication.

"For the next phase, according to the directives of the Minister of ESDM, the utilization of bioethanol biofuel has also been included in the Decree of the Minister of ESDM to be implemented at a minimum of 5% starting this 2026," Eniya stated during a formal hearing with Commission XII of the House of Representatives (DPR) in Jakarta on Thursday, June 4, 2026.

Initial distribution will focus exclusively on Java, the economic heartland of the archipelago, before expanding to other islands. The mandate specifically targets non-Public Service Obligation (non-PSO) fuels, meaning subsidized fuels heavily relied upon by lower-income consumers will remain unaffected during this opening phase.

Securing the Supply Chain

The government expressed high confidence in domestic production capabilities, dampening concerns over potential supply bottlenecks. Local bioethanol refiners are already delivering fuel-grade product boasting a purity level above 99%, meeting stringent automotive performance standards.

The Ministry of ESDM has successfully audited the country's biofuel infrastructure to map out initial procurement logistics.

"We have actively identified existing bioethanol plants in Indonesia, and several of them are already capable of producing fuel-grade bioethanol with a purity level of over 99%," Eniya explained to lawmakers during the parliamentary hearing. She added that three specific supply companies have been selected to anchor the initial rollout, with exact purchase volumes to be locked in by the upcoming ministerial decree.

This strategy expands on the ongoing market trial of Pertamax Green 95, an E5 fuel option currently sold at select Pertamina service stations. The impending decree will force commercial fuel retail networks to rapidly scale up their blending infrastructure to handle the mandatory volume surge.
