s global aviation faces mounting pressure to cut emissions, ASEAN has a critical window of opportunity to position itself at the forefront of a cleaner aviation future.
Aviation remains one of the most challenging sectors to decarbonize, accounting for 2.5 percent of global energy-related carbon dioxide emissions in 2023, with that figure projected to grow rapidly. Unlike power generation and most other transport sectors, aviation remains heavily dependent on liquid fuels because of current battery limitations.
With air traffic in Southeast Asia continuing to surge and emission policies tightening globally, sustainable aviation fuel (SAF) offers the most scalable near-term tool to reduce emissions while improving regional energy security.
Backed by abundant regional resources, ASEAN is uniquely positioned to become an international SAF hub – delivering significant economic and climate benefits. However, capturing this market will depend on how quickly member states can turn regional potential into a credible, scalable and internationally recognized supply chain.
The growing urgency around SAF is closely tied to global mandates aimed at mitigating aviation’s climate impact. Under the International Civil Aviation Organization’s (ICAO) Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), countries have agreed to systematically reduce emissions from international flights. Starting in 2027, these rules will apply more broadly across international routes, making compliance a necessity for regional carriers.
In response, several ASEAN countries are accelerating national measures to integrate SAF into commercial fuel blends. Regional demand for SAF is projected to skyrocket from 15,000 barrels per day in 2030 to over 700,000 barrels per day by 2050, with Indonesia, Malaysia and Singapore driving the bulk of this consumption.

This shifting demand is reflected in aggressive new national policies. As the region’s primary air hub, Singapore will require departing flights to use a 1 percent SAF blend starting this year, scaling up to 3-5 percent by 2030. Indonesia is targeting an initial 1 percent blend in 2027, with a long-term goal of achieving a 50 percent blend by 2060.
