Flight Operations Initiatives
The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), a post-2021 scheme for international airlines to achieve growth without increasing CO2 emissions, was adopted at the ICAO General Assembly in 2016. To control emissions there will be a need for technical innovations for aircraft, improvements in operations, use of bio jet fuel and utilization of emissions credits. ANA Group has begun preparations to implement CORSIA-related measures.
With the expansion of our international network we have launched the Fuel Efficiency Project, under which we have implemented such measures as introducing fuel-efficient aircraft, revising flight methods, cleaning engines to improve fuel efficiency, as well as making progress clearly visible and thereby further motivating employees to work toward our goals. As a result, by the end of fiscal year 2016 we achieved the initial target of reducing fuel consumption by 42,000 kiloliters.
The circumstances of ICAO and IATA
ICAO will not increase GHG (CO2) emissions after 2020 at the General Assembly in 2016 to achieve global goal of improving fuel efficiency of 2% on average on international aviation until 2050, "CNG 2020 "Was adopted.
Meanwhile, IATA made the following three ambitious action plans in response to ICAO's efforts.
- Stabilise net CO2 emissions from 2020 carbon-neutral
- From now until 2020 1.5% Improvement in fuel efficiency per year.
- -50% CO2 emissions from aviation by 2050
Towards More Efficient Use of Fuel
Fine dust from the atmosphere attach to compressors inside aircraft engines, leading to the deterioration of fuel efficiency. We regularly wash away the dust from engine compressors to recover engine performance, thereby improving fuel efficiency and reducing CO2 emissions.
The cleanliness of engines varies with the flight routes (such as domestic vs international). We are finding ways to effectively clean the engines, by making adjustments to our operations and monitoring engine cleanliness through exhaust temperature and washing the engines more frequently as necessary.
ANA advocates the planned cleaning of engines, taking advantage of night times when aircraft are parked in domestic airports. We are creating optimal cleaning interval plans for each engine type, determining target numbers of aircraft to clean per airport as we work to continuously improve fuel efficiency.
CORSIA Methods to Control Emissions
Purchasing Emissions Credits
The ICAO reached an agreement in 2016 to implement a CO2 emissions control program employing market mechanisms in the field of international aviation (Carbon Offsetting and Reduction Scheme for International Aviation, CORSIA). Specifically, the amount of CO2 emissions for international aviation will be capped at the average emissions value of 2019 and 2020, beginning in 2021. Until 2026 participation is voluntary. Japan has already announced its participation in the program, and ANA Group will engage in further CO2 reduction initiatives.
ICAO has listed four ways to limit CO2 emissions - technological innovation of aircraft, operational improvements, the use of bio jet fuels and employing market mechanisms. While we aim to achieve the ICAO agreement to curb CO2 emissions, we are expecting expanded application of market mechanisms as demand for air travel increases. Specifically, if CO2 emissions reductions surpass the reduction targets and legal requirements of non-international aviation sectors, the additional reduction amount can be purchased. By employing market mechanisms, if the cost required to reduce CO2 emissions by one ton in a certain sector is lower than the cost required to reduce the same one ton of CO2 emissions in the aviation sector, we will be able to reduce emissions more efficiently for the global environment than if we considered reducing the same amount in the limited field of aviation. The ANA Group will take advantage of this market mechanism to efficiently curb CO2 emissions.
Bio Jet Fuel Introduction Initiatives
The use of bio jet fuels is the focus of research and development initiatives in countries around the world, and preparations for the introduction of this type of fuel are under way. Japan has established the Committee for the Study of a Process Leading to Introduction of Bio Jet Fuel for the Olympic and Paralympic Games Tokyo 2020. ANA Group is working together with the Ministry of Economy, Trade and Industry; the Ministry of Land, Infrastructure, Transport and Tourism; the Scheduled Airlines Association of Japan; the Petroleum Association of Japan; the New Energy and Industrial Technology Development Organization (NEDO) and airport refueling companies to resolve this issue. In addition, we are supporting the development and commercialization of bio jet fuels refined from euglena, a type of microalgae.
ANA Carbon Offset Program
Responding to customers who are concerned about environment and global warming, the we offer the ANA Carbon Offset Program to offset the CO2 emitted by the aircraft flown.
We selected the global warming prevention project with the most stringent certification standards (J-VER, Gold Standard CDM/VER).
Customers can calculate their own emissions levels for each route and can purchase offsets by credit card at any time for past or future flights.
