Initiatives in Aircraft Flight Operations
Global Stance on the Environment
ICAO Movements
The ICAO has set a global target for improving international aviation fuel efficiency by an average 2% per year between 2021 and 2050. To achieve this goal, the ICAO adopted CNG2020 at its 2010 assembly as a mechanism to become greenhouse gas (CO2) neutral beginning in the year 2020.
CORSIA Adoption
The 2016 ICAO Assembly adopted an international aviation growth scheme for 2021 and beyond that does not increase CO2 emissions. This plan is called the Carbon Offsetting and Reduction Scheme for International Aviation, or CORSIA.
IATA Movements
- Carbon-neutral growth beginning with the year 2020
- Generate an average 1.5% fuel efficiency improvement between 2009 and 2020
- Net-Zero Carbon Emissions by 2050 (4 October 2021)
ANA Group's Initiatives for Reducing CO2 Emissions from Aircraft
ANA Group has reviewed its mid-term environmental targets for FY2030 and transition strategy to achieve a decarbonized society, and updated its transition scenario toward carbon neutrality by FY2050. By FY2030, we will reduce CO2 emissions on both international and domestic flights by at least 10% compared to FY 2019, net.
To achieve this goal, we will combine four strategic approaches (operational improvements and technological innovation of aircraft, etc., low-carbon aviation fuel through the use of SAF, emissions trading, and negative emission technologies*1), with the use of SAF at the core.We will achieve carbon neutrality by 2050 while also pursuing compatibility with economic rationality.

Improve flight operations
1.During Maintenance
Water Cleaning Engines / Test Operations
The ANA Group has developed a unique vehicle for cleaning engine compressor parts. Engine compressor parts become dirty with each use, reducing fuel efficiency. Regular cleaning restores full engine function.
We have also revised test operations and introduced other efficiencies, saving 1% on annual fuel usage in test operations.
Reduction of Aircraft Weight
A lighter aircraft can fly on less fuel and reduce CO2 emissions. The ANA Group is working to optimize the amount of water supplied to aircraft and reduce the weight of onboard equipment.
For example, we are digitizing "Wing Kingdom" and (in-flight magazine), changing the paper quality of "Sky Shop" and (shopping catalog) and reducing the number of pages, reviewing the amount of tableware and drinks installed, and removing equipment that is not used as much. In addition, by changing the manuals for pilots and cabin attendants from paper to the iPad, we were able to reduce the weight by 70%.
2.Creation of Flight Plans
Selection of Optimum Altitudes, Speed and Routes
In general, the lower the air density at high altitude, the lower the fuel consumption. Excessive speed increases fuel consumption. The weather conditions, routes that optimize fuel may vary from day to day. Pilots and dispatchers make flight plans for each flight, checking all types of information for each flight by selecting the optimum altitude, speed and route. Also, if a pilot operates multiple flights per day such as domestic routes, the next flight's information is sent to the pilot's iPad between flights and recreate the flight plan using the latest information.
3.While parking Aircraft
Reducing the Time of Auxiliary Power Unit (APU) Usage
In addition to the main engine on the wing, the aircraft is equipped with another jet engine called APU (auxiliary power unit) at the tail end. APU is responsible for the "compressed air" used for the operation of the main engine and air conditioning equipment at the time of departure, as well as the "Electric" required on the ground before the main engine starts. APU operation requires fuel and emits CO2. Instead of using an APU while parked on the ground, we connect GPUs (Ground Power Unit), which can supply power and air conditioning from the ground, to the aircraft, and we are working to shorten APU use time, thereby contributing to CO2 emissions reduction.
4.Takeoff
Reduced Flaps at Takeoff
The flap is called a high-lift device, and it is used to increase the area of the wing during takeoff. Increased flap angles and wing area has the advantage of being able to take off from shorter runways, but it also increases air resistance, requiring more power and fuel for the airplane to climb or accelerate.
Reduced flaps Takeoff such as from long runways, enables to reduce air resistance, fuel consumption and CO2 emissions.
5.During Climb
Climb with early acceleration
Climbing with acceleration at lower altitude after takeoff, retracting the flaps and reaching cruise altitude as soon as possible, enables to reduce fuel consumption.
6.During Cruise
Reviewing flight paths during flight using the latest weather information
In addition to creating a flight plan, the ANA Group checks weather information again after takeoff, and changes flight routes depending on the situation. This is called DARP (Dynamic Airborne Reroute Procedure).
This allows for more optimal fuel planning and flight routes, thereby reducing CO2 emissions.
7.During Descend
Promoting an Energy-Efficient Descent Method
Continuous Descent Operations is a method in which an aircraft descends continuously from the start of descent until the final approach point.
Relative to the operation descending in stages with periods of level flight, this method enables to shorten the flight distance and suppress excessive power during descent and reduce the fuel consumption, CO2 emission and noise. The ANA Group began implementing this method for late-night and early-morning flights at Kansai International Airport and is expanding its use to other applicable airports while cooperating with the relevant organizations.
Timing of Deploying Flaps
The airplane land with flaps, slowing down during the descent for landing.
Since the air resistance increases when the flaps are put out, the timing of putting out the flaps is delayed as much as possible, which leads to reduction of fuel consumption and CO2.
Timing of Lowering Landing Gear
The landing gear is used for landing and is lowered during the descent. Lowering the landing gear creates greater air resistance and increases fuel consumption. During the descent, the timing of lowering the landing gear is delayed as much as possible within the range where there are no safety issues, which reduces fuel consumption and reduces CO2 emissions.
8.Landing
Reducing Thrust Reverser Usage
The landed airplane uses a thrust reverser and brakes to decelerate. By using the reverser attached to the engine, it allows a temporarily increase in the power of the engine and can slow down the airplane's landing speed more quickly.
If the landing runway is long enough and there are no safety issues, lowering engine power while using the reverser will reduce fuel consumption, and CO2 emissions , and can also suppress noise.
Single-Engine Taxiing
After landing, even one engine can adequately taxi the airplane on the ground. The pilot will check the weather and the surrounding environment of the airplane and decide whether or not it can do so safely. By shutting down one engine and taxiing on the ground using the power of the other engine, it reduces fuel consumption and CO2 emissions.
9.Postflight
As a postflight procedure, the ground staff reviews and analyzes the flight data, and utilizes it for daily operations as well as for reducing environmental impact.
Adopt New Aircraft Technologies
Introduction of Fuel-Efficient Aircraft and Engines
We were the launch customer for the development of the highly fuel-efficient Boeing 787, which celebrated its 10th anniversary in service in 2021. As of the end of July 2022, the Group operates 77 of these aircraft (B787-8/-9/10) and is actively introducing state-of-the-art aircraft such as the Airbus A320neo and A321neo. As of the end of March 2024, 80.3% of the Group's aircraft (of jet aircraft) is fuel-efficient aircraft. Furthermore, a final purchase agreement has been signed for the introduction of Boeing 737-8 aircraft, scheduled for fiscal 2025 and thereafter. We also aim to have more than 100 Boeing 787 aircraft by FY2030 and will promote early conversion to fuel-efficient aircraft. We are working on a demonstration project to reduce air friction resistance during flight by applying a special shark-skin-like finish Opens in a new window.In the case of an external site,it may or may not meet accessibility guidelines. to the surface of the aircraft, thereby contributing to the reduction of CO2 emissions.
In our daily aircraft operations, we are working to reduce environmental impact by prioritizing the use of fuel-efficient aircraft.
Airframe modifications
First aircraft with Riblet technology implementation in service
ANA becomes the first individual airline in the world to equip both passenger and freighter version of the Boeing 777 with fuel-saving AeroSHARK technology, reducing drag and emissions.The first modified Boeing 777F (JA771F) began scheduled cargo flights, with plans to extend the AeroSHARK technology to a passenger aircraft (JA796A) by next spring in 2025, furthering ANA's commitment to investment in fuel efficient technologies that reduce emissions.
It results in estimated annual savings of approximately 250 metric tons of fuel and 800 metric tons of CO2 for each aircraft.
(Maximum predicted effect calculated by Lufthansa Technik based on ANA's average annual flight hours)
What is AeroSHARK?
AeroSHARK, a joint development by Lufthansa Technik and BASF, is a functional surface film inspired by the drag-reducing structure of sharkskin.
Equipping Aircraft with Winglets
Winglets are a type of wingtip devices fitted to the end of the main wings. Attaching winglets reduces air resistance that occurs during flight. The use of winglets on the Boeing 767-300ER, which is operated on long-haul flights, can improve fuel efficiency by around 5% and reduce per-aircraft CO2 emissions by 2,100 tons per year. In 2010, the ANA Group became the first domestic airline to attach winglets to a Boeing 767-300ER and has since then consecutively added wingtips to its Boeing B767-300ER fleet.
Introduction of Next-generation Paint System
We are employing a next-generation paint system that offers superior weather resistance in contrast with traditional coating, contains few volatile organic compounds, and which results in lighter aircraft.
Reducing the Weight of Cabin Seats
The ANA Group developed new standard seats for domestic routes in partnership with Toyota Boshoku Corporation.
By combining the ANA Group's know-how as an airline with Toyota Boshoku's manufacturing technologies cultivated over many years through the development of automobile seats, we developed comfortable seating that meets our technical specifications as well as our desire to provide a relaxing environment for all based on our policy of assuring our passengers a "memorable journey."In developing these seats, we managed to reduce the overall cabin weight by 195 kilograms per aircraft compared to conventional seating without compromising comfort. This weight reduction has, in turn, allowed us to cut our annual fuel consumption by approximately 15 kiloliters per aircraft.
ICAO Landing and Take-Off Cycle
The ICAO landing and take-off cycle is the cycle from take-off to 3,000 feet in elevation and from 3,000 feet in elevation to landing. Engine emissions are measured for engines within this cycle. Engine test criteria consist of the following output and operation hour criteria.
Output Conditions |
Rated Output (%) |
Operating Time (Minutes) |
---|---|---|
Take-Off | 100 | 0.7 |
Ascending | 85 | 2.2 |
Descending | 30 | 4.0 |
Ground Taxiing |
7 | 26.0 |
Utilization of SAF (Shift to Low-Carbon Aviation Fuel)
The use of SAF is at the core of the ANA Group's strategy to realize a decarbonized society.Our environmental goal is to replace at least 10% of the fuel we consume with SAF by FY2030, and by FY2050, almost all of the fuel we consume will be low-carbon.Currently, we are working with related companies and ministries to ensure a stable supply of domestically produced SAF.

Use Emission Trading Schemes
Emission trading schemes (purchase of carbon credits) represent one of the available methods to offset CO2 emissions in the overall global environment. We intend to use it as a short- to medium-term measure during the period when CO2 emissions cannot be fully reduced through the implementation of the aforementioned initiatives. In the long term, we aim to achieve carbon neutrality without relying on emission trading schemes.
Utilization of Negative Emissions Technologies (NETs)
The ANA Group plans to neutralize 1% of CO2 emitted by aircraft operations by 2030 and 10% by 2050 through utilizing Negative Emissions Technologies (NETs) such as direct air capture*1 and storage (DAC+S) that actively remove historic and residual CO2 emissions from the atmosphere. In addition, the ANA Group also plans to utilize air-captured CO2 as a raw material for aviation fuel. In March 2022, ANA signed a basic agreement with Climeworks*2, a Swiss start-up company working on DAC. Under this agreement, we began researching high-quality, permanent CO2 removal technology. In August 2023, we became the first airline in the world to sign a procurement contract with 1PointFive*3 of the U.S.. 1PointFive is constructing a DAC plant in Texas, U.S.A., which is expected to begin commercial operation by the end of 2025. ANA plans to procure more than 30,000 tons of carbon dioxide removal (CDR) credits over three years beginning 2025. In order to achieve carbon neutrality (NET ZERO) by 2050, we will work to capture CO2 directly from the atmosphere through Direct Air Capture (DAC) and other means to permanently "remove" CO2 that cannot be reduced through the use of SAF and other means.
- *1.Direct air capture (DAC): Technology to capture CO2 directly from the atmosphere.
- *2.Climeworks:
Climeworks empowers people to reverse climate change by permanently removing carbon dioxide from the air.
One of two things happens to the Climeworks air-captured carbon dioxide: either it is returned to earth, stored safely and permanently away for millions of years, or it is upcycled into climate-friendly products such as carbon-neutral fuels and materials.
The Climeworks direct air capture technology runs exclusively on clean energy, and the modular CO2 collectors can be stacked to build machines of any capacity. - *3.1PointFive社:
1PointFive is committed to reducing global temperature rise by 1.5 °C by 2050 through decarbonization solutions, including Carbon Engineering’s DAC technology, AIR TO FUELS™ technology, and geological storage hubs. AIR TO FUELS™ is a registered trademark of Carbon Engineering Ltd.
Lobbying and membership in industry associations related to climate change
In response to climate change risks, the government has set "2050 carbon neutrality" as a goal in line with the Paris Agreement, and the ANA Group has also set "2050 net zero" as a long-term goal and "2030 environmental goal" as a path to achieve it. To achieve this goal, ANA's CEO and other executives are participating in government committees, serving as board members of industry associations, and lobbying to contribute to climate change policy decisions in line with the Paris Agreement.
We have a structure in place to promote environmental issues including climate change, headed by the President and CEO of ANA Holdings, Inc. and chaired by the Chief ESG Promotion Officer (CEPO), who has the highest responsibility for promoting ESG management, as well as directors and executive officers of the Company and its group companies, The Group ESG Management Promotion Committee meets four times a year to discuss important policies and measures related to environmental issues, including climate change, and to monitor progress toward targets. Regular meetings enable us to conduct lobbying activities in line with global conditions.
The ANA Group's ESG management requires us to fulfill our responsibility to society by accurately understanding the demands of society and responding appropriately through dialogue with our diverse stakeholders (customers, employees, shareholders, investors, business partners, national, government, public offices, local governments, local communities, etc.). In response to the risks of climate change, the government has declared "2050 carbon neutrality "as a goal in line with the Paris Agreement, and the ANA Group has also committed to "2050 Net Zero" as the long-term, and "2030 Environmental Targets" as a path toward that goal. In order to achieve this goal, ANA's CEO and other executives are participating in government committees, joining industry associations as board members, and conducting lobbying activities to contribute to climate change policy decisions in line with the Paris Agreement.

Globally, NextGen in the U.S. and SESAR in Europe are making similar efforts, who are working in cooperation with CARATS' activities, with the aim of promoting efficient operations in the future.
We believe that a seamless air traffic control network can be constructed efficiently if various operational relationships share information in a timely manner.
Launch of the 'GOBLEU Project' in collaboration with JAXA
ANA Holdings, Inc. has launched the "GOBLEU Project" with the Japan Aerospace Exploration Agency (JAXA), a national organization, to observe the distribution of greenhouse gas concentrations from an aircraft window (i.e., in space) to accurately determine where greenhouse gases are generated and absorbed, utilizing the AVATAR project conceived by the ANA Group and observation equipment such as JAXA's Greenhouse Gases Observing Satellite "Ibuki". Since 2009, JAXA has been monitoring the increase in global greenhouse gases with the Greenhouse Gases Observing Satellite "IBUKI" (GOSAT). On the other hand, it is possible to obtain more detailed data than with satellites by flying at a lower altitude than with satellites by bringing observation equipment on board an aircraft. Therefore, from 2020, ANA and JAXA are teaming up to conduct the "GOBLEU Project" to observe (remote sensing) the distribution of atmospheric components on the earth's surface from an aircraft. In addition to actual greenhouse gas emissions, the observations can also measure the amount of greenhouse gases absorbed by plants through photosynthesis, and the accumulated results have been reported as one of the new observation methods at the COP28 Global Stocktaking.
This will make it possible to accurately determine where greenhouse gases are generated and absorbed. By observing the composition of the world's atmosphere from space, we aim to reduce greenhouse gases.
