Asean’s Next Generation of Biofuels Needs Resilience Beyond Blending

Why It Matters

Biofuel policies shape ASEAN’s energy security, fiscal health, and investment climate, making their design critical for a resilient, low‑carbon transport sector.

Key Takeaways

• Indonesia's B40 mandate aims for 14.2 bn L biodiesel by 2025
• Thailand used 1.14 bn L ethanol and 1.31 bn L biodiesel in 2025
• Oil price swings raise biofuel input costs, driving subsidy dependence
• Linking support to sustainability metrics can unlock carbon‑market revenues
• Second‑gen biofuels need feedstock contracts and clear standards to be bankable

Pulse Analysis

The rapid expansion of first‑generation biofuels in ASEAN reflects a pragmatic response to volatile oil markets and a desire to keep transport costs stable. Indonesia’s B40 mandate and Thailand’s long‑standing gasohol programme illustrate how blending mandates can replace millions of litres of imported diesel and gasoline, supporting domestic agriculture and creating jobs along the value chain. Yet the reliance on subsidies to keep biofuels price‑competitive exposes governments to fiscal risk, especially when oil‑linked inputs such as fertilizer and logistics become more expensive during price spikes.

A growing body of analysis suggests that sustainability governance can transform this liability into an asset. By implementing rigorous lifecycle accounting and monitoring‑reporting‑verification (MRV) systems, ASEAN nations can qualify biofuels for performance‑based incentives, including carbon‑market credits similar to Brazil’s RenovaBio scheme. These revenue streams reduce the need for blanket subsidies and improve investor confidence, while also addressing land‑use concerns that have plagued first‑generation feedstocks.

Looking ahead, the region’s resilience hinges on a phased shift toward second‑generation biofuels derived from waste and residues. To attract financing, projects must secure reliable feedstock supply contracts, adhere to transparent standards, and benefit from predictable, time‑bound policy support tied to emissions‑intensity reductions. A coordinated R&D roadmap under the APAEC 2026‑2030 plan could accelerate cost reductions and scale‑up, ensuring that biofuels remain a viable complement to electric‑vehicle adoption rather than a fiscal burden. This balanced approach positions biofuels as a strategic, low‑carbon bridge in ASEAN’s broader energy transition.
