The Philippines' Department of Energy is reviewing a sustainable aviation fuel (SAF) mandate, according to a Manila Times report, in a move that would bring the country's aviation sector into the regulatory framework now being adopted across multiple jurisdictions.

The published headline indicates the policy remains at the proposal stage. The DOE has not, on the basis of the published item, released a draft regulation, named a target blend percentage, or set an implementation date.

What a SAF mandate actually does

Sustainable aviation fuel is produced from non-fossil feedstocks including used cooking oil, agricultural residues, municipal waste, and synthetic e-kerosene. It trades at a premium to conventional Jet A-1, historically two to five times higher than fossil jet fuel depending on feedstock and pathway. A mandate typically obliges fuel suppliers — or in some frameworks, airlines directly — to blend a minimum percentage of SAF into uplift at specified airports, with compliance timelines ramping upward over a multi-year horizon.

How other jurisdictions have structured similar rules

The international benchmark is the European Union's ReFuelEU Aviation regulation, which sets a 2% SAF blend from 2025, rising to 6% by 2030, 20% by 2035, 34% by 2040, 42% by 2045, and 70% by 2050. The United Kingdom has legislated a 2% mandate from 2025 with a 10% target by 2030. Indonesia, the Philippines' closest regional peer, has run a SAF roadmap since 2020 and supported voluntary trials by Garuda Indonesia.

What it would mean for Philippine carriers

A Philippine mandate would land on an industry where SAF uptake remains limited. Cebu Pacific operated the country's first commercial flight using a SAF blend in 2022, using fuel supplied by a domestic producer. Philippine Airlines has separately participated in SAF-related trials. Operational SAF availability at Manila's Ninoy Aquino International Airport and at secondary gateways such as Cebu and Clark is, however, not yet established at scale, and any mandate would require either imported SAF or development of local refining capacity.

Why feedstock matters more than the headline

Feedstock availability could become a structural advantage for Manila. The Philippines produces large volumes of coconut oil, a recognized SAF precursor through the HEFA pathway, and is exploring power-to-liquid and alcohol-to-jet routes using sugarcane and cassava. A mandate that accepts internationally certified SAF would primarily impose a cost on carriers and on jet fuel importers. A mandate structured around local feedstock eligibility could create a captive demand pool for domestic producers and shift the balance of payments in their favour.

How the rule would interact with existing frameworks

The policy also intersects with the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), the ICAO-managed offsetting framework, and with EU and UK emissions rules that already cover Philippine-origin flights to those markets. Carriers exposed to multiple SAF regimes face the operational complexity of compliance accounting across jurisdictions, and any Philippine rule would need to specify whether locally produced SAF counts toward CORSIA baselines.

What happens next

Whether the Philippines moves from proposal to regulation, and on what timeline, will determine whether the policy functions primarily as a demand signal for local refining capacity or as a compliance cost on carriers. The DOE's next publication — a draft text, a stakeholder consultation document, or a named blend target — will clarify the direction.
