JAKARTA, INDONESIA / RankWire.AI / – The mandatory B50 biodiesel program in Indonesia is projected to save approximately 170 trillion rupiah, equivalent to US$10.8 billion, in foreign exchange in 2026, according to the Energy and Mineral Resources Ministry. This forecast accounts for reduced expenditure on imported diesel resulting from the country’s increased biodiesel blend. The policy mandates that diesel sold across the country contains 50% palm oil-derived biodiesel. Officials indicated that this measure boosts local fuel consumption while decreasing reliance on fossil diesel.
Indonesia launched the nationwide B50 program on July 1 and officially announced the mandate on July 9 in Karawang, West Java. This new blend replaces B40, which contained 40% biodiesel and became the national standard in 2025. B50 consists of equal parts fatty acid methyl ester, also known as FAME, and traditional diesel. The renewable component is supplied by palm oil, linking the fuel program to Indonesia’s domestic plantation and processing sectors.
The ministry compared the Rp170 trillion estimated savings with Rp133.3 trillion in foreign exchange savings under B40. It also projects that B50 will reduce fossil diesel consumption by about 4 million kilolitres. The government tasked state-owned Pertamina with managing the blending system and supporting distribution throughout the national fuel infrastructure. Fuel suppliers are allowed to utilize remaining B40 stocks through September as the market transitions to the higher biodiesel blend.
B50 Policy Promotes Increased Use of Palm-Based Fuel
Indonesia anticipates that B50 demand will require between 16.7 million and 18 million kilolitres of biodiesel. The initiative is also expected to utilize roughly 15.2 million to 16.3 million tonnes of crude palm oil. These volumes surpass the 15.64 million kilolitres allocated under the B40 scheme for 2026. The higher mandate aims to channel more domestically produced palm oil into transportation, industrial machinery, shipping, rail systems, and power generation sectors.
Official projections estimate the added value for the crude palm oil industry at 23.49 trillion rupiah. The government also claims that B50 could generate approximately 2.1 million jobs in farming, processing, logistics, and fuel distribution. Additionally, the ministry estimates the blend could reduce carbon dioxide emissions by as much as 44.46 million tonnes, compared to 39.66 million tonnes with B40.
Extensive Testing Supports the Nationwide Diesel Transition
Prior to implementation, the government conducted tests of B50 across various vehicles and machinery, including cars, trucks, mining equipment, agricultural machinery, trains, ships, and power plants. Automotive testing involved light vehicles covering over 50,000 kilometres and heavy vehicles exceeding 40,000 kilometres. Mining equipment was tested for approximately 1,000 operational hours, with no significant engine issues linked to fuel quality. The ministry confirmed that the tested fuel complied with government standards and the technical requirements of vehicle manufacturers.
Indonesia has gradually increased its biodiesel mandates over nearly two decades, starting with B2.5 in 2008, followed by B10 in 2013, B20 in 2018, B30 in 2020, B35 in 2023, and B40 in 2025 before reaching B50 this year. Each increment has been accompanied by updates to fuel standards, production capacity, storage, transportation, and distribution infrastructure to support nationwide adoption.
