Eco Friendly, Smart Airports

Kansai Airports Environmental Statement
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.

• Response 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.
Kansai Airports Group is fully aware of its responsibility toward the global and regional environmental
changes. We will continue to promote initiatives aimed to reduce our environmental impact and todevelop the airport while coexisting with the surrounding environment.

【Our environmental targets: (target year: FY 2022, base year: FY 2016)】
1. Reduce our energy use per unit of traffic by 1% per year on average.
2. At each airport, reduce our CO2 emissions per unit of traffic by 1% per year on average.
3. At each airport, reduce the use of city water per passenger by 2% per year on average.
4. Increase the rate of recycling to 35 %.
5. At each airport, reduce the use of single-use plastics by 25%
6. At each airport, achieve environmental certification such as Airport Carbon
Accreditation and ISO14001.
7. Perform biodiversity assessments and protect biodiversity in and around our airports.
8. Actively support the use of hydrogen as a clean energy source.

Response to Climate Change

Reduce GHG Emissions

CO2

At the Kansai Airport Group, we have actively committed
to measures intended to promote awareness of the needto reduce CO₂ emissions and help take the process
forward as part of our long-term target of net-zero GHG
emissions*, established in March 2021. In line withJapanese government policy with mid- and long-termgoals in mind, our airports are also working with the
Airport Environmental Promotion Council, which
represents airport-related businesses, to reduce CO₂
emissions. We will also consider a framework in which
eco-friendly businesses can participate.

We aim to calculate CO₂ emissions by categorizingthem into Scopes 1 to 3 in line with the GHG protocol
concept.
・ Scope1: CO₂ directly emitted by incinerating fuels used in
vehicles, emergency generators and othermachinery.
・ Scope2: CO₂ indirectly emitted when electricity is purchased
and used.
・ Scope3: CO₂ emitted by other businesses involved in airport
business activities.
＊ GHG protocol:
Universal standards for calculating and reporting on GHG emissions.

CO₂ emissions from airports

CO₂ emissions of Kansai Airports GroupKIX（tCO2）

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. The CO₂ emissions from facilities managed by
the Kansai Airports Group and related businesses also
decreased thanks to the emission-reduction efforts madeby airport-related businesses. Going forward, we will
strive to reduce energy use further and boost overall
energy efficiency at our airports via the Airport
Environmental Promotion Council.

carbon management plan to rein in CO2 emissions.
This plan outlines how we intend to reduce ourcarbon footprint going forward, including an energy
conservation promotion system, reduction targets
and medium to long-term plans.
Within the airport, the areas consuming mostenergy are the passenger terminal building andother building facilities, particularly air-conditioning
and lighting systems.
Accordingly, the airportʼs energy conservation
efforts focus on these facilities and systems.

[Major efforts]
・ Upgrading energy-efficient heat-source
equipment
・ Optimizing the ventilation system
・ Insulation and anti-sunlight measures
・ Optimizing the air-conditioning system
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.

● Lighting System● Optimizing energy-conservation
operation[Major efforts][Major efforts]

・ Full-scale upgrading to LED lighting
・ Expanding the brightness sensor and control

・ 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 andEnvironment Ambassadors within the Kansai
Airport Group patrol all three airports regularly toensure the facility configuration and operation is
set up to maximize energy saving; modifying
temperature settings and extinguishing lighting 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.

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.

We are encouraging the use of renewable energy and new forms of energy to lower our GHG emissions.

Solar Power

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.

Hydrogen Energy
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
19

outside the airport, we strive to build on results alreadyachieved and pave the way for further development.
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.

[Fuel-cell Forklifts][Fuel-cell Vehicles]

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.

A hydrogen station is able to service fuel-cell vehicles (FCV).
In future, it will also accommodate fuel-cell buses expected tooperate on limousine bus routes from ITAMI and as shuttle
buses operating within KIX.

Reduction of Clean Water Consumption

We have initiated various efforts to reduce clean water consumption at our airports.
In fiscal 2020, the total consumption figures for the three airports were 449,000, 201,000 and 19,000 m3 respectively.
Overall consumption declined compared to 2019, reflecting the far lower number of passengers due to COVID-19.
At KIX and KOBE, we utilize reclaimed (recycled) water and rainwater to meet around 30 to 40% of our water needs,
as part of efforts to optimally exploit water resources.

Eﬀorts to save water
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
adjustment.

Introducing the use of a food waste disposer in restaurants

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 temporarily closed due to the COVID-19 crisis, the disposer processes daily foodwaste at ITAMIʼs Oasis.
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.

This plant features a fluidized bed furnace. It also uses a filter-typeprecipitator that utilizes catalysts to remove nitrogen oxides, as well as
humidity-regulated fly ash stabilizing equipment. The plant was designedwith careful consideration of the local environment. Emissions at about
850°C from the incineratorʼs furnace are directed into a cooling chamber,through heat exchangers designed with heaters to prevent white smoke,and then to a reactor. Dust and hazardous gases are then removed by afilter-type precipitator, and exhaust gases are released into theatmosphere via an induced-draft fan and an exhaust stack. We operatewith strict voluntary standards at the stack outlets for dust, sulfur oxides,
hydrogen chlorides, and nitrogen oxides, with maximums of 0.02 g/Nm3,
20 ppm, 30 ppm and 70 ppm, respectively.

・ Utilization of land acquired through the relocation compensation program
The airport clears and plants trees on land purchased through the relocation compensation program located in theClass 3 area around the airport. As a result, a greenbelt (see photo below) that serves as a buffer zone between the
airport and surrounding communities is taking shape. With the progress of the relocation compensation program inClass 2 and 3 areas, there has been an increase in vacant sites (after residents have relocated) in the area.
Responding to community concerns about losing local cohesiveness, the airport has been working to develop green
space integrally in a planned way, by having Class 2 and 3 areas and surrounding areas designated as green space,as defined under the nation's City Planning Act. Examples include the Itami Sky Park on the Hyogo prefecture sideand Fureai Ryokuchi (public green space) on the Osaka prefecture side of the airport.
Also, the airport developed Air Front Oasis Shimogawara using land acquired in the Class 2 area as part of
the relocation compensation program. This area aims to familiarize local residents with the airport throughgreenery and it also serves to improve the disaster prevention functions of the surrounding communities. As
a result, the area improves the living environment of people in the surrounding communities along withdisaster preparedness.

Preserve Biodiversity

Establishing Seaweed Beds

At Kansai International Airport, we take an active
approach to establishing vibrant seaweed beds
surrounding the airport island to provide additional
habitat for marine life in Osaka Bay. At the time of the
airport island construction, sloping rock-fill seawalls
were primarily used and efforts were put intodeveloping the reclaimed shallow areas. As a result,
there is rich growth of seaweed around the airport
island which serves as habitat for various species offish and shellfish. At present, the airport aims tomaintain as well as expand the growth of high-quality
seaweed beds by conducting various surveys andexperiments including monitoring their condition.
In the monitoring survey conducted in March 2019, we
observed 59 hectares of seaweed bed area which isequivalent 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 thesurrounding environment and circumstances, as well
as regular monitoring.

Seaweed bed recovery installed on wave-dissipation blocks

Preserv e B i od i v er si t y

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. We then launched the project commensurate with work progress and thelife cycle of seaweed and taking all relevant measures into consideration.

[FY 2019]
Ultimately aiming to secure seaweed bed
areas under construction and pave theway for seaweed of the next generation to
thrive, we collected donor algae of
Ecklonia cava (a brown seaweed native toJapan) inhabiting seawalls in areas
housing wave-dissipation walls andtransplanted them to the phase 1 airport
island.

We then seeded the installed blocks using

for the wave-dissipation blocks. As well as
using eco-friendly blocks designed topromote seaweed growth, the work we
performed alongside them not only
involved striving to improve thedisaster-prevention functions but also tocreate 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 ouractivities utilizing the PDCA cycle.

International (ACI) when KIX and ITAMI received
Level 2* Airport Carbon Accreditation (ACA).
In December 2018, the ACA of KIX and ITAMI were
upgraded to Level 3 while KOBE also newly received
ACA Level 2.
Moreover, in November 2021, KIX, ITAMI and KOBE
were upgraded to an unprecedented Level 4 - a first inJapan.
This reflects our successful policy to date ofcommitting to a long-term goal of net-zero GHG
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.

We will continue striving to work with airport-related
businesses to reduce CO2 emissions and will consider
a framework in which eco-friendly businesses canparticipate.
＊ Airport Carbon Accreditation is an international evaluation andaccreditation program/system to manage and reduce CO 2
emissions from airports. As of November 2021, 357 airports areaccredited. It is the only environmental accreditation program

＊On April 1, 2018, Kansai Airports Kobe commenced
its business as an operator of Kobe Airport (KOBE).

R eferen ce D at a
Following the spread of COVID-19 infections, domestic and international travel and with it the number of passengers
and flights in KIX, ITAMI, and KOBE in 2020 declined significantly compared to 2019. CO 2 emissions, clean water
consumption, and waste decreased, but the decline in passenger and flight numbers resulted in the increase of the unitsof traffic* and the amount per passenger.
Even under such unusual circumstances, we will continue to promote efforts to reduce the environmental impact
through appropriate measures, such as improving the efficiency of energy use throughout the airport.
