Indonesia will begin implementing a B50 biodiesel blend on 1 July following nearly six months of technical trials across transport and industrial sectors. The policy raises the share of palm-based fuel in diesel to 50%, reflecting the government’s wider strategy to strengthen energy security, reduce dependence on imported fossil fuels and expand the use of domestic renewable resources. Officials say the rollout will be gradual, allowing time to monitor operational performance and ensure stable supply.
According to reporting from ANTARA, Energy Minister Bahlil Lahadalia confirmed that trials have been conducted across multiple sectors including heavy equipment, ships, trains and trucks. The testing phase assessed engine compatibility, fuel performance and distribution readiness ahead of nationwide implementation.
B50 Blend Expands Indonesia’s Biofuel Programme
The B50 fuel mix consists of 50% crude palm oil (CPO)-based biodiesel and 50% petroleum diesel. It represents the next step in Indonesia’s long-running biodiesel programme, which aims to reduce fuel imports while supporting domestic palm oil demand.
Indonesia currently enforces a B40 mandate, requiring diesel fuel to contain 40% palm-based biodiesel. According to the Energy Ministry, the B40 programme has already reduced diesel imports by approximately 3.3 million kilolitres (kL) and lowered carbon emissions by 38.88 million tonnes of CO2 equivalent.
Government figures show biodiesel utilisation reached 14.2 million kL in 2025, exceeding the national target of 13.5 million kL and achieving 105.2% of the planned volume.
Energy Security Drives Policy Shift
Minister Lahadalia said global geopolitical tensions, particularly in the Middle East, have underscored the risks faced by countries reliant on imported energy. Expanding the share of domestically produced biofuel is therefore seen as an important step toward strengthening national resilience.
The move aligns with President Prabowo Subianto’s broader strategy to improve energy security and reduce exposure to international fuel supply disruptions. Officials estimate that adopting the B50 mandate could reduce fossil fuel consumption by around 4 million kL each year.
Coordinating Economic Minister Airlangga Hartarto has also indicated the policy could generate fiscal savings. The government estimates the shift may reduce fuel subsidy spending by up to Rp48 trillion (US$2.81 billion).
Gradual Implementation Across Transport and Industry
State-owned energy company PT Pertamina has stated it is prepared to support the programme, including the supply and distribution of the higher biodiesel blend across the country.
Officials say the B50 rollout will be implemented in stages to ensure technical readiness across industries and transport systems that depend heavily on diesel fuel. Early monitoring will focus on operational performance, supply stability and potential engine or maintenance issues.
The biodiesel expansion forms part of Indonesia’s broader efforts to modernise critical sectors and strengthen national resilience through technology and domestic innovation. Similar ambitions are visible in areas such as digital transformation in public services, including initiatives highlighted in Indonesia’s adoption of AI to improve healthcare and transport systems.
As the world’s largest palm oil producer, Indonesia has progressively expanded biodiesel mandates over the past decade. Policymakers view the programme not only as an energy strategy but also as a mechanism to stabilise domestic palm oil markets while advancing emissions reduction goals.
