Philippine carriers are accelerating their decarbonization efforts through massive fleet investments and artificial intelligence as the industry faces mounting pressure to reduce its environmental impact.
Cebu Pacific made regional history in early 2025 by securing Southeast Asia’s first Sustainability-Linked Loan for a low-cost carrier. The financing facilitated the acquisition of a brand-new Airbus A321neo delivered on Dec. 23, 2024. This new engine option aircraft provides improved fuel efficiency that supports the airline’s goal to transition to an all-NEO fleet by 2028.
Under the terms of the loan, Cebu Pacific has committed to specific performance targets to reduce carbon emission intensity. Meeting these benchmarks will trigger financial incentives for the carrier.
The budget airline ranks 18th among global airlines with the lowest emissions according to the Cirium Flight Emissions Review. It is the only Philippine carrier to make the list, reporting 62.4 grams of CO2 per Available Seat Kilometer in 2024.
Cebu Pacific attributed its ranking to a strategy centered on modernization. In 2024, the company placed the largest aircraft order in Philippine history for up to 152 A320neo family aircraft.
The NEO fleet helped the carrier avoid an estimated 157,000 tonnes of CO2 emissions last year, with each plane delivering up to 20 percent fuel savings.
The airline has also transitioned its ground operations by deploying electric ground support equipment at Ninoy Aquino International Airport.
In May 2025, the carrier completed the first all-electric aircraft turnaround at Mactan-Cebu International Airport using electric units and bridge-mounted equipment. These initiatives contributed to the airline receiving an ESG score of 46 from S&P Global in 2024.
Philippine Airlines is also pursuing a different roadmap toward net zero emissions by 2050, aligning its targets with the Paris Climate Agreement. The flag carrier is collaborating with industry leaders to optimize fuel consumption through digital innovation.
PAL became the first Asian carrier to adopt SkyBreathe OnBoard, an AI-driven fuel management tool developed with OpenAirlines. The system provides pilots with real-time notifications to identify shortcuts and fuel-saving routes. Since its June 2024 launch, the technology has prevented 252 tonnes of CO2e from entering the atmosphere.
While the group currently uses biofuel-blended diesel and gasoline for ground operations, it is exploring the procurement of Sustainable Aviation Fuel for its long-haul fleet. Both carriers maintain that these sustainability investments are critical as they continue to service dozens of domestic and international destinations across Asia, Australia and the Middle East.
