JAKARTA, INDONESIA / RankWire.AI / – The B50 biodiesel program in Indonesia is projected to generate savings of approximately 170 trillion rupiah, or US$10.8 billion, in foreign exchange in 2026, according to the Energy and Mineral Resources Ministry. This forecast is based on decreased expenditure on imported diesel fuel following the increase of the national blend to 50% biodiesel. The regulation applies to diesel used in transportation, industry, shipping, railways, and power generation. The renewable component is derived from palm oil, while traditional diesel makes up the remaining half. The program aims to substitute part of Indonesia’s fossil fuel consumption with domestically produced biofuel.
Indonesia commenced nationwide B50 usage on July 1 and officially launched the mandate on July 9 in Karawang, West Java. It replaced the B40 mandate, which mandated a 40% biodiesel blend since 2025. B50 consists of equal parts fatty acid methyl ester, known as FAME, and petroleum diesel. The increased requirement encourages more palm oil to be consumed within the domestic fuel sector. Distributors are permitted to utilize remaining B40 stocks through September to facilitate the transition. Prior to the rollout, authorities introduced updated fuel standards and distribution strategies.
The Energy and Mineral Resources Ministry estimates that foreign exchange savings under the B40 program amount to Rp133.3 trillion. The projected savings with B50 are increased to Rp170 trillion for 2026. Officials also anticipate that the mandate will reduce fossil diesel consumption by approximately 4 million kilolitres. Pertamina has been tasked with overseeing fuel blending and supporting distribution nationwide. The company also manages storage and supply for regions involved in the program. The implementation includes technical controls for production, transportation, and retail distribution.
B50 policy boosts domestic biodiesel demand
Indonesia predicts that B50 will require between 16.7 million and 18 million kilolitres of biodiesel, surpassing the 15.64 million kilolitres allocated under the B40 plan for 2026. This mandate is also expected to utilize an estimated 15.2 million to 16.3 million tonnes of crude palm oil to meet demand. The supplies will serve road transport, industrial machinery, shipping, rail services, and electricity generation across various key fuel markets nationwide. The volume estimates are based on projected national demand under the new blend ratio.
The government’s projections suggest an added value of Rp23.49 trillion for Indonesia’s palm oil sector. The official assessment estimates that around 2.1 million jobs across farming, processing, logistics, and fuel distribution will benefit from the program. It is also estimated that B50 could cut carbon dioxide emissions by as much as 44.46 million tonnes, compared to 39.66 million tonnes projected for B40. These figures are part of the ministry’s overall evaluation of the higher biodiesel blend, considering the entire program rather than specific sectors or regions.
Testing phases preceded Indonesia’s B50 implementation
Prior to the nationwide rollout, the government conducted tests of B50 in cars, trucks, mining equipment, agricultural machinery, trains, ships, and power stations. The trials for light vehicles covered 50,000 kilometres, while heavy vehicles underwent testing over 40,000 kilometres. Mining machinery operated for roughly 1,000 hours without significant engine issues related to fuel quality. The ministry confirmed that the tested fuel met government standards and manufacturer specifications. These trials were completed before the official launch of the B50 program in July.
Indonesia has progressively increased its biodiesel requirement since introducing B2.5 in 2008, moving to B10 in 2013, B20 in 2018, B30 in 2020, B35 in 2023, and B40 in 2025. The B50 mandate is the latest step in this series of increases. Each phase required adjustments to fuel standards, production capacities, storage, and transportation infrastructure. The 2026 program now mandates an equal share of biodiesel and conventional diesel in the national fuel mix.
