Reference Data

Kansai Airports Group is engaged in various activities to reduce the impact on the environment at the
3 airports (Kansai International Airport, Osaka International Airport and Kobe Airport). In order tofurther promote our activities, we have created a new environmental plan “One Eco-Airport Plan,”and set specific targets and measures based on the following 4 pillars as indices for future initiatives
toward reduction of environmental impact.

• Adaptation to climate change
Having set a long-term goal of net zero greenhouse gas emissions by 2050, we promote efficientenergy use to reduce environmental footprint and implement measures aimed at reducing
greenhouse gas emissions. We also encourage the use of solar, hydrogen and other types ofrenewable and alternative energy to contribute to protecting the global environment.
• Resource usage
We reduce, separate, recycle and reuse all the waste and plastics generated. We also contributeto resource conservation through the promotion of “Reduce, Reuse and Recycle (the 3Rs)” of bothwaste and water. This includes making water use more efficient through data analysis, expanding
the use of recycled water and exploring the use of rainwater.
• Environmental harmony
We continue to work on reducing aircraft noise, conduct environmental monitoring appropriately
and disclose monitoring results. We also promote the creation of positive spaces where airport
users can relax and feel comfortable while striving to preserve biodiversity through themaintenance and expansion of greenbelts and conducting environmental surveys to verify species.
• Environmental management
Using environmental evaluation programs, we develop and refine a mechanism to assess,understand and reduce environmental footprint. We also make an effort to engage in dialogues
with customers, airport staff and local communities through the dissemination of environmental
information and the provision of environmental education, as well as alliances with airport-related
businesses and airports throughout Japan and overseas.

As well as introducing energy-efficient equipment,
we further promote energy conservation efforts in
our air-conditioning system by reducing the
air-conditioning load. This is done by utilizing
ambient air-cooling methods, controlling the inflow
of ambient air while the air-conditioning is active,
window insulation and anti-sunlight designs.

・ Visualizing and analyzing energy usage withBEMS
・ Optimizing operations using AI

We promote a switchover to LED throughout ourbuilding and aviation lighting as part of a plan to
upgrade systems and renovate facilities, while
introducing an energy-efficient transformer systemas part of electrical upgrades. Capitalizing on theopportunity to refine and install new equipment,
we promote energy conservation efforts over arange of systems.

As well as taking tangible measures that include
upgrading to energy-efficient equipment,
optimizing energy-conservation operations is also
one of our top priorities.
Energy Conservation Committee members within
the Kansai Airport Group patrol all three airports
regularly to ensure the facility configuration andoperation is set up to maximize energy saving;
modifying temperature settings and extinguishinglighting in non-operational areas.
When optimizing operational energy usage,
understanding issues flagged by data analysis
following energy visualization and continuing to
implement accurate measures are both important.
Accordingly, we establish a Building Energy
Management System (BEMS), with which we cancollect, manage, share and analyze energy data.
This system allows us to share daily and monthly
information via an energy dashboard,quantitatively analyze air-conditioning systems andanalyze data using BI tools.
Further, we are aiming to optimize automatic
operations by combining BEMS and AI.

CO₂ emissions of Kansai Airports Group

Thanks to energy-saving efforts and scope to reduce theproportion of electricity emissions, the Kansai Airports
Group reduced overall CO₂ emissions by 11.0% in fiscal
2019, before the COVID-19 crises emerged, compared to
the level in fiscal 2016. A year later, in fiscal 2020, overall
CO₂ emissions fell even more sharply due to the impact of
COVID-19. Amid the ongoing impact of COVID-19, overall
CO2 emissions in fiscal 2021 were unchanged from theprevious year.
The CO₂ emissions of the Kansai Airports Group also
decreased thanks to its emission-reduction efforts.
Going forward, we will strive to reduce energy
consumption further and boost overall energy efficiency at
our airports via the Airport Environmental Promotion
Council.

Energy-Eﬃcient Air-Conditioning System

Since February 2020, we have initiatedenergy-saving measures for facility operations in
response to the significant downturn in airline
demand due to the COVID-19 crisis. In fiscal 2021,
given the declining demand for international travel,
KIX continued reviewing the scope of partial facility
closure, although ITAMI and KOBE airports haverecovered their operation to almost pre-crisis levels,reflecting a resurgence in demand for national
airlines.
Electricity and gas consumption in KIX for fiscal 2021
declined due to the COVID crisis. Meanwhile,
although the operation of ITAMI and KOBE airports
are almost back to normal, their energy consumption
has been declining compared to fiscal 2019 or earlier,before the COVID-19 crisis emerged.
In ITAMI and KOBE airports, throughout the 2016 to
2021 period, electricity and gas consumption
declined by around 10% and 40-60%, respectively.
Electricity consumption was reduced following
ongoing efforts to save power, such as upgrading to
LED lighting. A lower gas consumption was achievedby upgrading to energy-efficient inverter-controlled
electric turbo chillers in ITAMI airport and improving
the operation of heat source equipment in KOBE.

Upgrading to LED lighting

T2 Smart Air-Conditioning Demonstration Experiment

In FYs 2018 and 2019, we upgraded the apron and offices
to LED lighting. Overall, we were able to reduce annual
emissions by approximately 650 tCO2.
We also introduced LED lighting when renovating the
ITAMI terminal building, which reopened in August 2020.
Meanwhile, we have been renovating the ceiling of theterminal building in KOBE in FY 2021 and the T1
renovation in KIX is underway and set to continue until
2026.

We installed automatic
curtains and applied
heat-shielding paint to
the waiting room of theterminal building.

Joint research with

LED lighting in theterminal building (ITAMI)

In July 2021, a demonstration experiment of an
air-conditioning system promoting energy-saving
and infection-control was launched in Terminal 2 at
KIX.
The system helps control infections as well as
reducing the energy used for air-conditioning by
efficiently combining an anti-infection installation
alongside the existing air-conditioning system.
The infection-control technology eliminates virusesby directly applying UV light to circulating ambientair.
It also inactivates existing viruses by disseminating
low-level ozone generated by the UV application.
Finally, with energy-saving in mind, the systemcarefully controls the areas, timing and volume of
air-conditioning on an as-required basis, based on
the amount of human traffic and other indoor
environmental conditions to ensure efficient
air-conditioning.
Reducing the amount of building ventilation is
generally an effective way to save energy.

However, given the need for constant circulation of
fresh air to prevent the spread of COVID-19, it iscurrently infeasible. Even so, this system manages toreduce ventilation, help control infection and saveenergy consumed by air-conditioning all simultaneously,
by efficiently disseminating disinfected air over a wider
space.
We strive to reduce the energy used for air-conditioning
and virus infection risk by 50% and 95%, respectively,by operating these technologies and incorporating AI.
We have implemented this demonstration projectcommissioned by the Ministry of the Environment jointlywith Kobe University.

Small Wind Turbines

In February 2014, KIX Megasolar commenced
operations using solar panels installed at a site on thesouth side of the phase 2 airport island and on the
Phase 2 International Cargo Area rooftop. The airport
began operating a solar power system installed on therooftop of the Phase 1 International Cargo Area in
September 2015, later extending the scope to the roofof the Nankai Bus Terminal in the Domestic Cargo
Area in March 2016. Further expanding the initiative,
February 2020 saw a solar power system come into
operation on the rooftop of the Terminal 2 building topromote the spread of solar power onsite. This clean
energy installation now generates sufficient power tocover around 10% of total electricity use in KIX.

As a first for Japanese airports, KIX began operating a small
5kW wind turbine as part of a trial in September 2014 andnow has t h r e e o f t h e s e t u r b i n e s i n o p e r a t i o n . The
electricity they generate is used to power the streetlights
inside KIX Sky Park.

In anticipation of the hydrogen society on the horizon,
KIX is promoting the use of hydrogen in collaboration
with airport businesses and working towards thelarge-scale introduction of hydrogen energy for airport
facilities and vehicles. The airport marked the full-scalelaunch of the Hydrogen Grid Project in May 2014 andactively engaged in testing fuel-cell forklifts for practicalapplications; establishing a model case involving the useof hydrogen at airports and other activities.
Hydrogen is the ultimate form of clean energy;
generating only water after combustion. It can also be
stored and shipped easily, so users can use it whenever
and wherever needed. To make carbon-free operation a
reality in a venue like an airport, covering a large area
and operating around the clock, expanding the use ofhydrogen energy will become important. Given
technological trends in terms of hydrogen energy
innovation and the status of hydrogen energy use
outside the airport, we strive to build on results already

Currently, commercial hydrogen stations for fuel-cellvehicles (FCVs) and fuel-cell buses (FC buses) have been
installed at both KIX and ITAMI, while a hydrogen-charging
facility for fuel-cell industrial vehicles were also installed at
KIX. Establishing this kind of infrastructure reflects our wish
to expand the use of fuel-cell vehicles.
The Kansai Airport Group currently uses five FCVs within
KIX and ITAMI. In KIX, 22 fuel-cell forklifts (FCFLs) wereintroduced in the CKTS import cargo building and currently
operate in the KIX International Cargo Area. Most forklifts,
except the large type, were replaced with FCFLs at the
CTKS import cargo building. Since FCFLs generate minimal
noise and zero exhaust fumes, it helps mitigate theenvironmental impact and vastly improve the working
environment.
In March 2022, we cooperated with Nankai Bus Co., Ltd. tointroduce fuel-cell buses operating within KIX. This marked
a first for Osaka Prefecture to introduce fuel-cell buses on afull scale.

ITAMI[Fuel-cell Forklifts][Fuel-cell Vehicles and Fuel-cell Buses]

In April 2017, the airport completed work on Japanʼ s firsthydrogen station for industrial vehicles at the International Cargo
Area that includes liquid hydrogen tanks and high pressurehydrogen supply lines. The largest trial operation in Japan usinghydrogen station and fuel-cell forklifts is now taking place.
Introducing fuel-cell forklifts to handle air cargo 24 hours a day
can help to lower CO2 emissions compared to forklifts powered byfossil fuel or electricity. In addition, fuel-cell forklifts can berefueled in around three minutes, meaning they can be operated
continuously without the hassle of charging or replacing battery
packs. As a result, they can offer significant improvements in both
work efficiency and work environment.

Infrastructure has been established at both KIX and ITAMI
airports to enable hydrogen filling for FC (fuel-cell) vehicles aswell as FC buses.

Kansai Airports is spearheading a number of initiatives to conserve water, including installing low flowtoilets whenremodeling terminal buildings. In FY 2020, as well as introducing systems and equipment, we applied dailyawareness to further refine our operations. Given the obvious excess usage of water over and above the required
amount at many restrooms in the terminal building, we promote efforts to optimize the amount of water consumed
by automatic water faucets. With customers in mind, we started the optimization process by determining the wateramount management standards, confirming the flow of water on site and reconfiguring settings when the baseline
was exceeded. Collectively, these efforts help reduce the environmental load in the long term with a single

Reducing waste and recycling

As part of efforts to reduce and recycle waste, we introduced a food waste disposer
in KIXʼs restaurant and ITAMIʼs restaurant “Oasis”. Although the restaurant in KIX
is was temporarily closed due to the COV ID-19 crisis, the restaurant it reopened inJune 2022 and the disposer processes daily food waste.
This disposer biodegrades food waste using microbes, which, once decomposed, isdischarged into the sewage system. Eliminating transport, burning and otherprocessing on site allows us to reduce the volume of waste to be incinerated andCO 2 emissions from incinerating garbage bags as well as reducing the transportdemands on staff.
We will strive to roll out the disposer to as many restaurants and tenants in theterminal building as possible to reduce the amount of food waste incinerated
airport-wide.

Preserve Biodiversity

In response to the damage caused by Typhoon No. 21 in 2018, wave-dissipation blocks were installed on the southand east sides of the first-phase airport island as part of disaster-prevention measures. Since it was envisaged thatsome existing seaweed beds would be lost in the process, we launched a seaweed bed recovery project to restore
the seaweed environment as early as possible after the block installation; initiating measures as early as FY 2019,a whole year before starting installation. For three years until fiscal 2021 when the block installation wascompleted, we proceeded with the project commensurate with work progress and the life cycle of seaweed taking
all relevant measures into consideration.

At Kansai International Airport, we take an active approach toestablishing vibrant seaweed beds surrounding the airport island toprovide additional habitat for marine life in Osaka Bay. At the time of
the airport island construction, sloping rock-fill seawalls wereprimarily used and efforts were put into developing the reclaimed
shallow areas. As a result, there is rich growth of seaweed aroundthe airport island which serves as habitat for various species of fishand shellfish. At present, the airport aims to maintain as well as
expand the growth of high-quality seaweed beds by conducting
various surveys and experiments including monitoring theircondition.
In the monitoring survey conducted in March 2022, we observed 54
hectares of seaweed bed area which is equivalent to about 20% of
all seaweed bed areas in the Osaka Bay. To conserve preferable
seaweed beds, we consider it important to consider/carry out
measures taken in accordance with changes in the surrounding
environment and circumstances, as well as regular monitoring.
Recently, the key role of blue carbon incorporated in seaweed beds,
shallow areas and other marine ecosystems has been acknowledged
as one of the effective CO₂ sink-enhancing measures to achieve a
decarbonized society. Accordingly, we continue to help build asustainable society by conserving the seaweed environment.

Ultimately aiming to secure seaweed bed areas
under construction and pave the way forseaweed of the next generation to thrive, wecollected donor algae of Ecklonia cava (a brownseaweed native to Japan)
inhabiting seawalls in areas housing
wave-dissipation walls and transplanted them tothe phase 2 airport island.
We then seeded the installed blocks using donor
algae from Ecklonia cava and Sargassum
inhabiting the installation site for thewave-dissipation blocks. As well as using
eco-friendly blocks designed to promoteseaweed growth, the work we performed
alongside them not only involved striving to
improve the disaster-prevention functions but
also to create a seaweed bed environment. We
used all-natural materials to transplant donor
algae and promote an eco-friendly project. In
2020 we also tried to provide seeds using
biodegradable spore bags. Despite the seaweed
bed recovery being impacted by external factors
and involving repeated trial and error, we
promote our activities utilizing the PDCA cycle.
During a September 2021 survey, Ecklonia cava
was observed on the new wave-dissipation
blocks. However, considering recent damage
sustained by Ecklonia cava due to algae-eating
fish, we would like to continue monitoring thestatus and attempt to create seaweed beds witha view of their multifaceted functions.

emissions by 2050, as exemplified by the Kansai
Airport Environmental Statement. Equally, it echoes
our quest to achieve the mid- and long-term goals of
the Japanese Government to reduce GHG, as
reconfirmed by the Airport Environmental Promotion
Committee comprising of airport-related businesses.

Our Initiatives: Kansai International Airport

Cooperation with airport-related businesses
We cooperate with airport-related businesses and domestic/international airports and reflect these efforts in our
airport activities.
The COVID-19 crisis made FY 2021 persistently challenging for cooperation. Even so, we continued striving to share
information and dialog via online meetings.

In April 2022, Kansai Airports enacted Environmental
Standard Regulations for its business partners to promote
environmentally friendly business practices across its airports.
The Regulations set out matters to be observed in reducing
environmental burdens and clearly reaffirmed the groupʼ scommitment to social responsibility as an airport operator.
We will also renew contracts with tenants in phase to include
clauses on environmental standards.

Presentation during a dialog session of a platform to bring
the Kansai Hydrogen Supply Chain Initiative to fruition
Kansai Airports is a member of a platform to materialize the Kansai Hydrogen Supply Chain Initiative which wasestablished to share issues and consider their solutions and specific hydrogen implementation under the collaboration
between businesses and supporting organizations to materialize the Kansai Hydrogen Supply Chain Initiative. During
a FC forklift dialog session held in March 2022 to promote information-sharing, discussion and interaction among
stakeholders, we provided participants with our cases of introducing and utilizing FCFL at KIX.

Environmentally advanced airports working
in cooperation with airport business operators

Airport Environmental Promotion Committee initiatives
We have set up councils comprising of representatives from airport-related businesses at each of our airports to share
best business practices and collectively engage in various efforts with business to help mitigate the environmental
impacts. These include initiatives for energy conservation, reducing CO2 emissions, reducing and recycling waste andencouraging the use of eco-friendly vehicles.
Since cooperation with airport-related businesses is key to helping decarbonize the airport, we will promote ouractivity and strive to consolidate even stronger cooperation going forward.

In July 2021, the Civil Aviation Bureau of the Ministry of Land, Infrastructure, Transport and Tourism invited a public
offering and selected “Priority Survey Airport” to advance efforts to reduce CO2 emissions from airport facilities andvehicles as well as engaging in specific consideration to make airports renewable energy bases to promote theirdecarbonization. KIX, ITAMI and KOBE operated by the Kansai Airports Group were selected, and case studies wereconducted to verify our environmental activities.

In-house environmental education

Participation in Airports Council International (ACI)

Environmental Ambassador Initiatives

Kansai Airports is a member of Airports Council International, an organization representing 717 organizations thatmanage 1,950 airports in 185 countries and regions worldwide (at the time of writing). It is also a member of the ACI
Asia-Pacific Regional Environment Committee. This committee met for the 14th and 15th times in March 2021 andMarch and April 2022, respectively, in virtual online events, at which attendees actively discussed airport
environmental initiatives.
In seminars held during the committee and stakeholder meeting hosted by ACI World, the Kansai Airport Group
presented its decarbonization efforts centering on the introduction of renewable energy and the use of hydrogen andshared case studies with members and stakeholders.

Kansai Airports Group has introduced Environment Ambassador
Initiatives to raise the environmental awareness of all employees,
Environmental Ambassadors are members assigned by the individual
sections of each group company who oversee the task of sharing theknowledge and insights they have obtained through initiatives with allother employees.
We will continue awareness-raising activities, including regularly
disseminating environmental information and creating learning content
to help evangelize our environmental initiatives.

Presentation at the ICAO Stocktaking Seminar
During the ICAO* Stocktaking Seminar held in September 2021,
the Kansai Airport Group showcased a range of initiatives
centering on a roadmap towards decarbonization and the use ofhydrogen energy in airports and shared information with
airport-related and aviation-related stakeholders.

Environmental initiatives through an In-house Award Program
We invited ideas for the environment from Kansai Airport Group employees and commended the best of them.
Over 50 wide-ranging proposals were received, the best of which were honored with the CEO Prize, Co-CEO Prize andother prizes. Award-winning ideas are being brought to fruition by a project team. Some, such as introducing internalcarbon pricing (ICP), have already been realized.

＊ ICAO： International Civil Aviation Organization

Published in the ICAO Environmental Report 2022
Kansai Airportsʼ initiatives to promote the use of hydrogen energy and ramp up solar power
generation were included in the ICAO Environmental Report 2022, issued by ICAO in September 2022.
This report shares information on the progress made over the last three years in key areas of ICAOʼ senvironmental protection activities. Collectively, the technical and scientific articles compiled here
inform the public of the work of the ICAO Secretariat, ICAO Member States and the many otherstakeholders involved. As such, it is considered as the benchmark reference document withininternational aviation and environmental sectors.

Following the spread of COVID-19 infections, 2021 saw domestic and international travel, air passenger numbers andflights in KIX, ITAMI and KOBE decline even further from 2020 compared to 2019 and pre-pandemic. Eventually, CO₂
emissions, clean water consumption and general waste amount have decreased while the units of traffic and amountper passenger remain high. Despite such unusual circumstances, we will continue striving to mitigate theenvironmental impact through appropriate measures, such as improving energy efficiency throughout the airport.
