Singapore Launches SAFCo to Centralize Sustainable Aviation Fuel Procurement
Singapore establishes SAFCo to centralize sustainable aviation fuel buying, funded by a passenger levy, aiming for greener aviation by 2030.
The global aviation industry stands at a critical juncture, facing the immense challenge of decarbonization. As air travel continues to grow, its environmental footprint, currently accounting for 2-3% of global carbon emissions, is under intense scrutiny. In response, the sector has committed to an ambitious goal of achieving net-zero emissions by 2050. A key pillar of this transition is SAF, a cleaner alternative to traditional jet fuel. However, its widespread adoption is hampered by significant hurdles, namely limited production and high costs.
In a decisive move to address these challenges and cement its status as a forward-thinking aviation hub, Singapore has announced a novel strategy. The city-state will establish a centralized, state-owned entity to manage the procurement of SAF for airlines operating out of its world-class airports. This initiative, a core component of the nation’s Sustainable Air Hub Blueprint, aims to create a stable demand signal for SAF producers, secure more competitive pricing through bulk purchasing, and accelerate the aviation sector’s journey toward Sustainability. The plan is not just a policy statement; it’s a structured, funded approach that could set a precedent for the rest of the world.
This new model is underpinned by a passenger levy, demonstrating a shared-responsibility approach to a complex global problem. By creating a dedicated, non-profit company to oversee this process, Singapore is building an ecosystem designed to stimulate investment, drive down costs, and ensure a steady supply of green jet fuel. The move is being watched closely by international bodies and other nations, as its success could provide a scalable blueprint for decarbonizing the skies globally.
At the heart of Singapore’s strategy is the Singapore Sustainable Aviation Fuel Company (SAFCo), a wholly-owned, non-profit subsidiary of the Civil Aviation Authority of Singapore (CAAS). Set to become operational in 2025, SAFCo’s primary mandate is to aggregate the demand for SAF from all Airlines at Changi and Seletar airports. By acting as a single, large-scale buyer, the entity aims to overcome the fragmented nature of airline fuel purchasing and provide the market with a strong, consistent demand signal. This is expected to encourage producers to invest in scaling up production, which is crucial for bringing down the high cost of SAF.
The financial engine for this initiative will be a levy imposed on all passengers departing from Singapore, scheduled to take effect in 2026. This “polluter pays” principle is designed to be equitable, with costs varying by flight distance and class of travel. Early estimates suggest the levy for an economy class ticket could be around S$3 for short-haul flights, S$6 for medium-haul, and S$16 for long-haul journeys. The final figures are anticipated to be confirmed by the end of 2025, providing clarity to both travelers and airlines. This funding mechanism ensures that the procurement of cleaner fuel is directly supported by the users of the aviation services.
Leadership for SAFCo has been drawn from both the public and private sectors to ensure a blend of regulatory oversight and industry expertise. The company’s board will be chaired by Han Kok Juan, the Director-General of CAAS, ensuring alignment with national aviation policy. The appointment of Tan Seow Hui, a former executive from Shell’s low-carbon solutions division, as chief executive brings deep industry knowledge and a practical understanding of the energy transition. This leadership structure is designed to navigate the complexities of the nascent SAF market effectively.
“Through SAFCo, we want to get the best value for the SAF levy collected and activate a SAF ecosystem which will help advance sustainable aviation and create new economic opportunities for Singapore and beyond.”, Han Kok Juan, Director-General of CAAS and Chairman of SAFCo.
The creation of SAFCo is not an isolated policy but a critical pillar of the comprehensive Singapore Sustainable Air Hub Blueprint, which was unveiled in February 2024. This blueprint is the nation’s roadmap to achieving net-zero aviation emissions by 2050. The strategy acknowledges that SAF is the most significant tool available for decarbonization, projected to account for approximately 65% of the required carbon emission reductions. The initial targets are clear: SAF is to constitute 1% of all jet fuel used at Singapore’s Airports in 2026, with an ambition to increase this to 3-5% by 2030.
These Strategy, while seemingly modest, represent a significant step forward given the current state of the global SAF market. Globally, SAF production accounts for less than 0.1% of total jet fuel consumption. The International Air Transport Association (IATA) projects that even with production doubling in 2025, it will still only meet 0.7% of the industry’s needs. Singapore’s mandated targets, therefore, place it at the forefront of SAF adoption and are intended to catalyze market growth. The centralized procurement model is designed to de-risk the process for both airlines and producers, creating a more stable and predictable market environment. The initiative also has implications beyond Singapore’s borders. The CAAS has actively shared its centralized procurement concept with the International Civil Aviation Organization (ICAO), positioning it as a potential model for other countries. As nations worldwide grapple with how to implement their own decarbonization strategies, Singapore’s proactive and structured approach offers a tangible example. It aligns with a growing global trend of government mandates for SAF usage, seen in regions like the European Union and the United Kingdom, which are collectively pushing the industry toward a more sustainable future.
Singapore’s establishment of a centralized company for SAF procurement marks a pragmatic and pioneering step in the aviation industry’s fight against climate change. By directly addressing the core challenges of high cost and uncertain demand, the SAFCo model presents a clear, actionable plan. It moves beyond pledges and commitments to create a tangible mechanism for change, funded by a transparent passenger levy. This strategic initiative not only advances Singapore’s own ambitious environmental goals but also reinforces its position as a global leader in aviation innovation.
The success of this model could have a ripple effect across the globe, providing a blueprint for other nations seeking to accelerate their transition to sustainable aviation. As SAFCo begins its operations, the industry will be watching closely to see if this centralized approach can indeed stimulate production, stabilize prices, and make green jet fuel a viable, mainstream reality. Ultimately, Singapore’s bold move is more than just a national policy; it’s a critical test case in the collective, global effort to ensure that the future of air travel is environmentally sustainable.

Airbus-led ECLIF-X Campaign Studies Aviation Non-CO2 Emissions 2025-2027
The ECLIF-X campaign investigates how low-sulphur and low-aromatic fuels reduce contrail formation and non-CO2 emissions in aviation from 2025 to 2027.
This article is based on an official press release from Airbus.
In a closely coordinated chase across the sky, the aviation industry is taking aim at one of its most visible and complex climate challenges: condensation trails. While carbon dioxide emissions have long dominated sustainability discussions, recent scientific consensus highlights that non-CO2 emissions account for a significant portion of commercial aviation’s total climate warming impact.
To address this, Airbus, the German Aerospace Center (DLR), and engine manufacturer Pratt & Whitney have launched ECLIF-X (Emissions and Climate Impact of alternative Fuels – X). According to an official Airbus press release, this joint research campaign utilizes a “flying laboratory” to investigate the effects of fuel composition on aviation’s non-CO2 impact.
Running from 2025 to 2027, the ECLIF-X campaign captures real-time data on how low-sulphur and low-aromatic fuels interact with advanced engine combustors. At AirPro News, we recognize this initiative as a critical step toward understanding and mitigating the formation of climate-warming contrails before new environmental regulations take full effect.
The methodology behind the ECLIF-X campaign involves two aircraft flying in tandem at cruising altitude. The “emitter” is an Airbus A321XLR test aircraft (registration MSN11058), powered by Pratt & Whitney PW1100G-JM engines. Research reports indicate these engines are equipped with the TALON-X rich-burn combustor, a technology specifically designed to reduce soot emissions. During the tests, the A321XLR is flown with three different types of fuel to compare their respective emission profiles.
Following closely behind is the “sniffer,” DLR’s heavily instrumented Falcon 20E research aircraft. Drawing on over 30 years of atmospheric research expertise, DLR scientists pilot the Falcon 20E directly into the exhaust wake of the A321XLR.
Flying at distances of just 50 to 300 meters, the Falcon 20E captures precise, real-time data on the physical and chemical properties of the emissions before they dissipate.
This proximity allows researchers to analyze the exhaust plume in real-time, providing unprecedented insights into the immediate atmospheric reactions triggered by different fuel blends.
Contrails are line-shaped ice clouds that form when hot, humid engine exhaust mixes with cold, high-altitude air. Depending on atmospheric conditions, these contrails can persist and spread into cirrus clouds that trap outgoing infrared radiation from the Earth. According to industry research, studies suggest that non-CO2 effects could represent anywhere from 35% to roughly two-thirds of aviation’s total accumulated climate impact. Airbus refers to the microphysics of contrail formation as the “sticky seed” problem. Conventional jet fuel contains aromatic compounds, which are the primary precursors for soot particles during combustion. These soot particles act as the foundational condensation nuclei, or “seeds,” for contrails. Furthermore, even trace amounts of sulphur in jet fuel result in the formation of sulphuric acid. This acid coats the soot particles, making them “sticky” and highly attractive to water vapor.
By utilizing fuels with low aromatics and low sulphur, such as highly refined Sustainable Aviation Fuels (SAF), engines produce significantly fewer soot particles and less sulphuric acid. Fewer seeds mean fewer ice crystals, resulting in contrails that are thinner, shorter-lived, or completely prevented.
The current campaign builds upon the landmark ECLIF3 study, which concluded in 2024. Data from ECLIF3 proved that flying on 100% SAF reduced the number of contrail ice crystals by 56% and cut the overall climate-warming impact of contrails by at least 26% compared to conventional jet fuel.
The ECLIF-X research arrives at a critical regulatory juncture. As of January 2025, the European Union Emissions Trading System (EU ETS) requires airlines to monitor and report their non-CO2 effects. With the first verified reports due in 2026, the industry faces immediate pressure to understand and quantify these emissions.
The introduction of the EU’s Non-CO2 Aviation Effects Tracking System (NEATS) means airlines are now legally required to track these metrics. Research initiatives like ECLIF-X provide the foundational science necessary to create accurate monitoring, reporting, and verification (MRV) models for the commercial aviation sector.
We view the ECLIF-X campaign as a pivotal transition point for airline operations. Historically, the push for Sustainable Aviation Fuel has been framed almost entirely around lifecycle carbon reduction. However, the empirical data gathered by Airbus and DLR highlights a crucial dual benefit: SAF physically alters the clouds aircraft leave behind.
Beyond fuel certification, this research paves the way for “climate-friendly routing.” As airlines and meteorologists better understand exactly how and when contrails form, flight dispatchers could soon pair clean fuels with tactical flight path adjustments to avoid atmospheric regions prone to persistent contrail formation. This operational shift will likely become a standard practice as regulatory bodies tighten non-CO2 reporting requirements.

SHEIN Expands Sustainable Aviation Fuel Use with DHL Partnership
SHEIN partners with DHL Express to pilot Sustainable Aviation Fuel in air freight, supporting emissions reduction amid market and regulatory challenges.
This article is based on an official press release from SHEIN.
On March 24, 2026, global fashion retailer SHEIN announced a new agreement with DHL Express to utilize the logistics provider’s GoGreen Plus service. This initiative integrates Sustainable Aviation Fuel (SAF) into SHEIN’s international air freight operations, marking another step in the company’s efforts to address lifecycle emissions associated with its supply chain.
According to the official press release, the partnership is designed as an early-stage pilot to help the retailer evaluate economic feasibility, certification frameworks, and operational integration. SHEIN explicitly acknowledges that the immediate emissions impact will be modest relative to its total air transport footprint, reflecting broader constraints in the global SAF market where alternative fuels represent only a fraction of conventional jet fuel supply.
We note that this move builds upon SHEIN’s previous SAF pilot programs initiated in 2025, signaling a continued corporate push to support capacity-building activities and demand signaling, particularly within the rapidly evolving Asia-Pacific (APAC) region.
Under the new agreement, SHEIN will leverage DHL’s GoGreen Plus service, which utilizes an “insetting” approach to reduce Scope 3 greenhouse gas emissions. Rather than fueling specific cargo planes directly with SAF, the fuel is introduced into DHL’s broader aviation network. The resulting lifecycle emissions reductions are then allocated to SHEIN using internationally recognized carbon accounting and certification frameworks.
“Signing the GoGreen Plus agreement with SHEIN marks another important milestone in DHL Express’s commitment to driving the green transformation of air logistics. As a long-term partner in SHEIN’s global logistics network, we are pleased to work together to explore how sustainable aviation fuel can be integrated into their air cargo operations.”
The DHL partnership is part of a broader, multi-carrier strategy. Industry research highlights that in 2025, SHEIN procured 187.3 tonnes of SAF across 14 Atlas Air charter flights, achieving an estimated emissions reduction of 579.1 tonnes of COâ‚‚ equivalent (tCOâ‚‚e). Furthermore, the company signed a Memorandum of Understanding (MoU) with Lufthansa Cargo in August 2025 to accelerate SAF adoption.
Regionally, SHEIN is also participating in a China-based SAF pilot program organized by China National Aviation Fuel (CNAF) and the Second Research Institute of Civil Aviation of China (CASRI). Through this initiative, the retailer plans to procure an initial batch of SAF from Air China Cargo, utilizing traceability mechanisms to track usage.
“Working with partners such as DHL allows us to better understand how sustainable aviation fuel solutions may be incorporated into air cargo logistics. Initiatives like this are part of SHEIN’s broader efforts to explore how emerging approaches across the aviation sector may contribute to addressing carbon emissions associated with air transport.”
SHEIN’s press release notes that wider adoption of SAF remains constrained by limited production capacity and higher costs. Data from the International Air Transport Association (IATA) released in December 2025 provides stark context for these limitations. According to IATA, global SAF production reached 1.9 million metric tons in 2025. While this doubled the output of 2024, it still represented only 0.6% of total global jet fuel consumption. Growth is projected to slow slightly in 2026, reaching an estimated 2.4 million metric tons, or roughly 0.8% of global demand. Furthermore, SAF currently trades at two to five times the price of conventional fossil jet fuel. IATA estimates that this premium added approximately $3.6 billion to the aviation industry’s fuel costs in 2025 alone.
The macroeconomic challenges are compounded by regulatory friction. IATA has publicly criticized certain regional mandates, arguing that they have distorted markets and increased compliance costs without guaranteeing adequate fuel supply.
“SAF production growth fell short of expectations as poorly designed mandates stalled momentum in the fledgling SAF industry… If the objective is to increase SAF production to further the decarbonization of aviation, then they [policymakers] need to learn from failure and work with the airline industry to design incentives that will work.”
The press release emphasizes strengthening the demand signal for SAF in the Asia-Pacific region through capacity-building activities. Industry data shows that APAC is currently undergoing a massive shift in SAF infrastructure and regulation, transitioning from voluntary goals to concrete mandates.
Singapore implemented a confirmed goal of 1% SAF by 2026, funded by a passenger levy, while Japan is finalizing a 10% SAF mandate by 2030. South Korea, India, and Indonesia are also rolling out blending roadmaps expected to take effect around 2027.
To support this regulatory push, physical infrastructure is scaling up. Neste operates a significantly expanded SAF refinery in Singapore, and Hong Kong-based EcoCeres is expanding into Malaysia. Additionally, in May 2025, the World Economic Forum (WEF) and GenZero launched “Green Fuel Forward,” an initiative specifically designed to scale SAF demand and build regional capacity for aviation decarbonization in APAC, involving major airlines and logistics firms like DHL.
SHEIN’s latest announcement reflects a maturing corporate approach to aviation decarbonization. By explicitly stating that the emissions impact of these early-stage pilots will be “modest,” the company avoids the pitfalls of greenwashing and aligns its messaging with the stark realities of the global SAF market. The reliance on DHL’s GoGreen Plus “book-and-claim” model highlights that, for global shippers, insetting remains the most viable mechanism to participate in the SAF economy without requiring direct physical access to alternative fuels at every origin airport. As APAC mandates like Singapore’s 2026 target take effect, corporate demand signals from high-volume freight users like SHEIN will be critical in justifying the massive capital expenditures required for regional SAF refineries.
GoGreen Plus is a service offered by DHL Express that allows customers to reduce the Scope 3 carbon emissions associated with their freight. It uses an “insetting” or “book-and-claim” model, where DHL purchases Sustainable Aviation Fuel (SAF) and introduces it into its broader aviation network, allocating the certified emissions reductions to the participating customer.
According to December 2025 data from the International Air Transport Association (IATA), SAF accounts for only 0.6% of global jet fuel consumption, constrained by limited production capacity and high costs. SAF is currently two to five times more expensive than conventional fossil jet fuel due to the high costs of feedstock collection, complex refining processes, and a lack of scaled production infrastructure globally.

Aviation Capital Group Publishes 2025 Sustainability Report Highlighting Fleet Modernization
Aviation Capital Group’s 2025 Sustainability Report details fleet modernization, emissions reductions, and new sustainability-linked financial commitments.
This article is based on an official press release from Aviation Capital Group.
Aviation Capital Group (ACG), a prominent global full-service aircraft asset manager, has officially p-shed its 2025 Sustainability Report. The document marks the company’s fifth annual review detailing its progress across key environmental, social, and governance (ESG) priorities.
According to the company’s press release, the 2025 report highlights significant strides in fleet modernization and emissions reductions. As the aviation industry faces mounting pressure to decarbonize, aircraft lessors are increasingly prioritizing newer, more fuel-efficient technology to meet long-term climate targets.
The newly released data underscores ACG’s ongoing transition toward a lower-emission portfolio, supported by strategic financial mechanisms and a growing backlog of next-generation aircraft commitments.
In its official press release, ACG reported that new generation, lower-emissions aircraft now account for 79% of its total fleet. This shift is the result of a deliberate fleet renewal strategy executed throughout the year. During 2025, the lessor added 52 new generation aircraft to its portfolio while simultaneously exiting 36 older generation airframes.
These modernization efforts have yielded measurable environmental benefits. ACG stated that it successfully reduced its relative emissions to 13% below its 2018 baseline. Furthermore, the company noted that its portfolio’s relative emissions are now 14% below the broader aviation industry average.
Looking ahead, the lessor continues to build its pipeline of modern aircraft. As of February 2026, ACG has increased its future aircraft commitments to more than 180 aircraft, ensuring a steady influx of fuel-efficient technology in the coming years.
Beyond fleet metrics, the 2025 Sustainability Report outlines ACG’s integration of ESG principles into its financial and corporate operations. The company announced the extension and upsizing of its Sustainability Linked Loan, which now totals $575 million. Additionally, ACG signed its first Sustainability Linked Leases, aligning its leasing structures with environmental performance metrics. On the social responsibility front, the press release highlighted that ACG contributed to more than 20 worthy causes worldwide during the 2025 calendar year.
Company leadership emphasized the importance of these initiatives in the context of broader industry goals.
“I am pleased to share ACG’s 2025 Sustainability Report, which reflects the progress we have made embedding sustainability, social responsibility and governance excellence into all aspects of our business. While the path to achieving net zero by 2050 is becoming increasingly demanding, we remain committed to shaping a sustainable future by deepening our impact as a business and broadening our influence across the wider aviation ecosystem through action, leadership, and collaboration.”
, Thomas Baker, Chief Executive Officer and President of ACG, in a company statement.
We observe that aircraft leasing companies like Aviation Capital Group play a pivotal role in the aviation industry’s transition to net-zero emissions. Because lessors finance a substantial portion of the global commercial fleet, their procurement decisions directly influence the speed at which older, less efficient aircraft are retired.
By tying financial instruments, such as the $575 million Sustainability Linked Loan and newly introduced Sustainability Linked Leases, to environmental targets, lessors create tangible economic incentives for airlines to operate cleaner aircraft. ACG’s reported metric of maintaining portfolio emissions 14% below the industry average demonstrates how aggressive fleet renewal strategies can outpace the broader market’s decarbonization curve.
Founded in 1989, Aviation Capital Group is a premier full-service aircraft asset manager and a wholly owned subsidiary of Tokyo Century Corporation. According to the company, it has approximately 450 owned, managed, and committed aircraft as of December 31, 2025.
As of the end of 2025, ACG leases its aircraft to roughly 85 airlines operating in approximately 50 countries worldwide.
The company reported that its future aircraft commitments have grown to more than 180 aircraft as of February 2026, focusing heavily on new generation, lower-emissions technology.
