The Cirium Flight Emissions Review has recognized Cebu Pacific as among airlines with the lowest emissions in the world. The report, published in July 2025, found that Cebu Pacific emitted 62.4 grams of CO2 per Available Seat Kilometer in 2024, placing the airline at 18th in global rankings – the only Philippine carrier to make the list.
Cirium is the world’s premier aviation data and analytics solutions company, with a 115-year history in the industry. Their Flight Emissions Review is among the most rigorous sustainability reports in aviation, using the EmeraldSky methodology for fuel burn and CO2 emissions to achieve greater than 99% accuracy on the report’s metrics. For Cebu Pacific to make it into the 20 lowest-emission airlines based on this review is a testament to the carrier’s commitment to sustainability.
“We are pleased to receive this recognition, which affirms that our efforts are making a real impact. By investing in modern, fuel-efficient aircraft and adopting new technologies, we aim to keep fares affordable while making flying more sustainable for Filipinos,” said Aileen Isidro, CEB Vice President for Corporate Strategy.
Cebu Pacific’s ranking can be attributed to a comprehensive decarbonization strategy anchored on fleet modernization and operational efficiency. In 2024, the airline placed the largest aircraft order in Philippine history—up to 152 aircraft in the A320neo family. This fleet saved an estimated 157,000 tonnes of CO2 emissions last year, with each aircraft delivering up to 20% fuel savings compared to previous-generation models.
Cebu Pacific also became the first low-cost carrier (LCC) in Southeast Asia to finance a brand-new A321neo through a sustainability-linked loan (SLL), tying financing costs directly to emissions-reduction performance.
Beyond its fleet, the carrier also advanced its sustainability efforts on the ground through a number of infrastructure and operational improvements. Cebu Pacific led the way in deploying electric ground support equipment at Ninoy Aquino International Airport (NAIA), and in May 2025 completed the country’s first all-electric aircraft turnaround, powered entirely by electric GSE and bridge-mounted equipment (BME). These actions have boosted the carrier’s global sustainability ratings, with its highest-ever ESG score of 46 from S&P Global in 2024.
With 36 domestic and 27 international destinations across Asia, Australia, and the Middle East, Cebu Pacific remains committed to decarbonizing its operations, while continuing to provide safe, reliable, and affordable air travel for its passengers.
