Fuel-saving Measures
By leveraging big data analytics, we identify opportunities to improve fuel efficiency and reduce carbon emissions across our flight operations. In response to evolving operating conditions, we actively develop and implement effective fuel-saving intiavtives, progressively embedding these practices into our standard operating procedures. Recognizing that each initiative has distinct characteristics, we apply customized evaluation criteria to accurately quantify the effectiveness of every fuel-saving initiative.
In 2025, EVA Air implemented 9 major fuel-saving initiatives, which delivered fuel savings of 14,341 tonnes compared with the baseline. This is equivalent to 170,556 MWh of energy and an estimated reduction of 45,317 tCO2e emissions.

Strategy / Actions |
| Improving Load Factors |
In 2025, EVA Air achieved a passenger load factor of 77.79% and a cargo load factor of 71.46% through the following initiatives:
- Expanded the route network and optimized capacity deployment to meet market demand.
- Cargo volume increased by 6.91%, supported by strong demand for AI servers, semiconductors, and e-commerce shipments. Secure medium- and long-term block space agreements and charter contracts with customers, together with the expansion of cold-chain services, and optimized freighter deployment further improved cargo load factors.
- Enhanced onboard products and services while expanding automated services to improve the travel experience.
|
| Low-drag Paint or Alternative Coatings |
From 2017 onward, mica-based paint coatings have been eliminated from all newly delivered aircraft and from routine repainting of the existing fleet to reduce aircraft weight.
|
| On-board Aircraft Weight Reduction |
- Promoting paperless cockpit and cabin by replacing newspapers and magazines with electronic publications and adopting Electronic Flight Bags (EFBs) for flight crews
- Replacing aging ULDs with lightweight ones.
- Refining loading practices by optimizing potable water and cabin service supplies, while introducing an outstation laundering program for inflight service items to reduce weight.
- Refuel accurately according to captain’s fuel order to avoid unnecessary fuel uplift.
- Implemented dynamic taxi fuel planning in flight plan.
- Where dispatch requirements permit, alternate airport with lower planned diversion fuel is planned in the flight plan.
|
| Improved on-board technology for route planning |
- Continuously evaluate flight planning service providers and implement system with advanced optimization engine to determine the most fuel-efficient routes and flight levels while accounting for complex airspace restrictions and weather conditions.
- Weather update service is provided to flight crew to access real-time weather information during flight and allow the computer to compute the optimal cruising altitude. If air traffic control (ATC) permits, cruise at the optimal flight level to improve fuel efficiency. Weather update service is also used when there is a route change to enhance fuel prediction accuracy.
|
| Airframe Modifications |
- Adopted manufacturer performance improvement packages for new aircraft whenever available and continuously evaluated retrofit options for the existing fleet.
- As the first airline in Asia to collaborate with Lufthansa Technik AG, we tested AeroSHARK riblet film on one of 777 freighters. This technology is expected to improve fuel efficiency by approximately 1%. Subject to successful trail, the technology may be rolled out across the wider fleet.
|
| Engine Upgrades/replacement |
- Continued monitoring aviation technology industry and introducing next-generation fuel-efficient aircraft to replace aging aircraft.
- Performed regular engine washing to improve fuel efficiency and reduce average exhaust gas temperature by approximately 10°C
- Evaluated engine foam cleaning as an alternative to conventional water washing, with an estimated fuel saving of 0.2–0.3%.
- Worked with engine manufacturers to implement Service Bulletin upgrades to restore engine performance.
|
| Other Fuel Efficiency Initiatives |
- Applied continuous descent operations (CDO), delayed landing configuration deployment or low-drag landing configurations, and single-engine taxiing after landing whenever operationally feasible and approved by air traffic control (ATC).
- Used ground support equipment (GSE) instead of the auxiliary power unit (APU) during ground operations whenever available.
- Optimized aircraft loading center of gravity (CG) to improve fuel efficiency.
- Prioritized the use of GSE over the APU during maintenance activities. Regularly inspecting flight control alignment and cleaning aircraft surfaces to reduce aerodynamic drag.

Fuel Efficiency and Emission Intensity
As air travel gradually recovered from the COVID-19 pandemic in 2022, passenger load factors improved while the use of passenger aircraft for cargo transport declined, resulting in significant improvements in both passenger and cargo fuel efficiency. In 2023, aviation demand continued to grow, leading to year-on-year increases in both fuel consumption and transport capacity. Nevertheless, the introduction of new-generation aircraft and the continued implementation of fuel-saving initiatives enabled EVA Air to maintain stable fuel efficiency for both passenger and cargo operations, with only minor fluctuations. EVA Air also continues to increase the use of SAF to reduce carbon emissions intensity, laying the foundation for lower-carbon flight operations.
