Kansai International Airport
Environmental Report 2017

About this Environmental Report
The “Environmental Report 2017” provides detailed data on the environmental initiatives conductedin fiscal 2016, and the categories of policy and measures described herein correspond to our Third
Environmental Plan, adopted in April 2013.
Environmental activities of the Kansai International Airport
At the Kansai International Airport we have been working to achieve thirty environmental targets tominimize impacts on the environment (air, water, etc.) for the entire airport island, based on the KansaiInternational Airport Environmental Plan adopted in June 2001.
With the start of service of Runway B (August 2007), a new Environmental Plan (second edition) was
adopted in March 2008, and we have been working since then to reduce environmental impacts fromairport-related operations, and also to reduce impacts on the region around the airport.
The management of Kansai International Airport and Osaka International Airport was integrated in July
2012. The third edition of the Environmental Plan was adopted in April 2013 as a compilation of “smart”
initiatives for a new environmentally friendly type of airport. Building upon our previous efforts, the latest
edition aims to make this a “smart” airport—good for people and good for the planet—through initiatives
such as the use of clean energy and better energy efficiency through the use of advanced information
technologies.
In 2016, Kansai Airports began managing the airports and has been working to further reduce environmental
impacts, as articulated in the Kansai Airports Environmental Declaration.

1. Environmental Plan
■ Key components
1. Plan period: Five fiscal years, from 2013 to 2017.
2. Target activities and area: The target area includes the entire area of Kansai International Airport,
and in order to consider all environmental impacts associated with airport operations, the target activities
include the activities of all users and all businesses/operators involved in airport operations. The airport
operator is to take the lead on activities that are within its control, while actively seeking cooperationfrom airport business operators and users.
3. Targets: Targets are to be established, as quantitatively as possible, to promote and evaluate the levelof achievement of the Plan, and the status of achievement is to be verified and published regularly. An
effort shall be made to monitor progress with implementation of the Plan as well as other factors, such as
international circumstances relating to climate change countermeasures. The targets are to be revised as
appropriate.
4. Organizational structure: The airport operator is to advance and manage (review and improve) thePlan through the internal Environmental Management Committee, in cooperation with airport businesses
and operators in the Smart Island Council, and others.
5. Energy management: Electricity consumption and generation on the airport island are to be
managed in an integrated way, and energy conservation is to be promoted, including reducing electricity
consumption during peak times.
■ Basic Principles
Initiatives are promoted based on the concepts of “safety and security,” “improving customer
satisfaction,” and “environmental measures.” With the expansion of area covered by the Kansai
Innovation Comprehensive Special Zone for International Competitiveness Development we areengaged in initiatives toward the realization of the Smart Island Vision for an environmentally-advanced
airport. This we do in cooperation with members of the KIX Smart Island Council, on the basic
principles of “green innovation” (implementation of “smart community” model projects, etc.), “ecooperations” (reduction of total energy use at the airport overall), and “eco relations” (reduction of
impacts on the local environment as a pollution-free airport).

■ Basic Policies

1. An airport that respects the local
environment

Continue to comply with environmental standards for aircraft noise and work to further
reduce noise levels. Work to protect the environment by not only meeting government
regulations for air and water quality, but also by setting our own voluntary standards
that are even more stringent.

2. An airport that respects the global
environment

Cooperate with the relevant contractors and businesses to show leadership in reducing
greenhouse gas emissions arising from activities. Also, promote the introduction of clean
energy through the use of renewable energy such as photovoltaics and hydrogen.

3. An airport that recycles resources

Continue with efforts to reduce the amount of waste generated and to make efficient useof the waste that does get generated, in order to make this an airport that recycles
resources. Also, work to ensure that water recycling systems make efficient use of water
resources, such as through efforts to promote the use of reclaimed water.

4. An airport that respects biodiversity

Create seaweed habitat around the airport seawalls and maintain them as habitat for adiversity of flora and fauna. Also, increase the amount of greenery on airport grounds,
and improve the surroundings to give airport users a sense of comfort and relaxation.

5. An airport that respects the local community

Aim for good communication with the local community and airport users, provide
information to domestic and international users about environmental monitoring and ourenvironmental activities, and provide diverse opportunities to promote an understandingof airport activities.

22. Environmental management structure and monitoring system■ Organizational structure
The airport operator advances and manages (reviews and improves) the Plan through the internal Environmental
Management Committee, in cooperation with airport business operators in the Smart Island Council, and others. Efforts arealso made to share information with the Energy Conservation Committee.

■ Environmental monitoring system
The environmental conditions around KIX are monitored in order to track the impacts of airport-related operations,construction, and so on. An environmental monitoring plan has been developed under the guidance and direction of the
Kansai International Airport Environmental Surveillance Organization (members include the governor of Osaka Prefecture
and mayors of nine cities and four towns in the nearby Senshu District). Aircraft noise, air quality, water quality, aquatic life
and other environmental parameters are checked regularly. The results of monitoring are reported to the relevant
governmental organizations in the form of monthly and annual reports, and are also available at the Kansai International
Airport Environmental Center.

33. Fiscal 2016 environmental data overview

 Quantitative targets
We establish targets in order toevaluate progress on efforts
articulated in the Plan. Where
possible, we establish quantitative
targets (e.g., air quality, water
quality, energy usage, greenhousegas emissions, recycling rates) for
quantifiable
categories.
For
categories where quantitative targets
are more difficult to establish, we
still make our best effort to quantify
the status of our initiatives.

5. Environmental initiatives:(1) An airport that respects the local environment
KIX was built five kilometers off the coast of the Senshu District in order to minimize the impactsof aircraft noise. Measurements of aircraft noise have shown that environmental standards arebeing met at all monitoring sites. For emissions from our incineration plant and wastewater
discharged from our wastewater treatment plant, we have voluntarily set standards that are more
stringent than required by regulations, in an effort to minimize our impacts on the environment.

■ Efforts to minimize the impacts of aircraft noise
Environmental assessments based on flight paths and flight procedures established to minimize aircraft
noise found that only areas over water were affected by noise levels exceeding environmental quality
standards.
KIX conducts both continuous andperiodic monitoring of aircraft noise,and publishes the findings. For fiscal
2016, as in the prior year, noiselevels complied with environmental
standards (maximum Lden 57 dB,
see Note 1) at all land-based
continuous monitoring stations andperiodic monitoring sites.

Efforts to minimize the impacts of aircraft noise○ Measures at noise sources
・Use quieter aircraft (Note 2)○ Flight paths and aircraft operation
・ Aircraft are expected to fly over land only aftergaining sufficient altitude over Osaka Bay after
takeoff from the runway.
・ Aircraft arriving or departing late at night or in early morning are restricted to flight paths in airspace over
Akashi Strait and Kitan Strait.
・ Flight procedures have been adopted to minimize noise from aircraft approaching the airport from Kitan Strait(Note 3).
・ Continuous descent flight procedures have been adopted (Note 4).
○ Our initiatives
・ Continue monitoring for compliance with established flight paths and altitudes.
・ Communicate with KIX Airline Operations Council to request that members observe established flight paths
and give due consideration to the need to minimize noise, etc.
For Notes 1 to 4, please see page 34.

■ Complaints, inquiries, and responses
Aircraft noise
The annual number of complaints and inquiries peaked at 263 in fiscal 1998 when new flight paths wereintroduced in airspace over the Osaka Prefecture region, and since then have been on a declining trend.
The majority of complaints and inquiries were about individual aircraft being too loud or flying too low,or queries about whether aircraft were staying on their regular flight paths. In response, we study theseissues in cooperation with the Civil Aviation Bureau (under the Japanese Ministry of Land,
Infrastructure, Transport and Tourism) and publish our findings. We will continue to respond
appropriately to complaints and inquiries.

■ Measures to reduce emissions from incineration plant (Clean Center)
General waste from the airport island isseparated into combustibles and recyclables,
and combustible waste is then incinerated at
our incineration plant. Emissions fromincineration go through a filter-typeprecipitator. The installation of a garbage
shredder has significantly improved thefurnace’s incineration efficiency; air
pollutant levels such as nitrogen oxides are
below regulated emission standards. Dioxin
emissions are also well below regulated
standards. Waste heat from incineration is
being used as a source of heat for theincinerator, and for hot water and air
conditioning at the incineration plant.

Incineration plant (Clean Center)
Plant description
This plant is designed with a fluidized bed furnace. It alsouses a filter-type precipitator that uses catalysts to remove
nitrogen oxides, as well as humidity-regulated fly ash
stabilizing equipment. The plant was designed with carefulconsideration of the local environment.
Exhaust gas flow
Emissions at about 850℃ from the incinerator’s furnace
are directed into a cooling chamber, through heatexchangers designed with heaters to prevent white smoke(Note 5, page 34), and then to a reactor. Dust andhazardous gases are then removed by a filter-typeprecipitator, and exhaust gases are released into theatmosphere via an induced-draft fan and an exhaust stack.
We operate with strict voluntary standards at the stackoutlets for dust, sulfur oxides, hydrogen chlorides, andnitrogen oxides, with maximums of 0.02 g/Nm3, 20 ppm,
30 ppm and 70 ppm, respectively.

■ Advanced treatment of general wastewater
General wastewater from airport-related facilities is directed to a wastewater treatment plant foradvanced treatment before being discharged. The treated water being discharged is significantly cleaner
than legally-required standards, based on our own more stringent voluntary standards (e.g., COD daily
average 12 mg/L, and further tightened to 10 mg/L starting in fiscal 2014). Our laboratory is equippedwith a variety of testing equipment, which ensures rigorous control of water quality until the point
treated water is discharged into Osaka Bay. We also strive to maximize the effective use of water
resources and to consider the local environment, such as by using some of the advanced-treatment waterfor flush toilets and the watering of plants.

Wastewater treatment plant
Wastewater from the passenger terminal buildings and other airport facilities is considered to be generalwastewater, and undergoes advanced treatment such as activated-sludge circulation nitrification/denitrification,
chemical clarification (coagulation/sedimentation), and rapid sand filtration. Special wastewater fromindustrial sources first undergoes onsite pre-processing to remove hazardous substances, and then undergoes
advanced treatment at the wastewater treatment plant, through chemical coagulation/sedimentation and rapid
sand filtration processes, etc. After advanced treatment, the treated water is reused as reclaimed water for
airport flush toilets, watering plants, etc., and any surplus amount is discharged into the sea.
Treatment capacity

General wastewater 10,050 m3/day
Special wastewater 3,300 m3/day

In fiscal 2016, average processed volumes were 2,194 m3/day of general wastewater, and 225 m3/day of special
wastewater.

Kansai International Airport promotes energy conservation measures through the Energy Conservation Committee.
In internal operations we are putting efforts into green purchasing, energy conservation, and going paperless. In
December 2016, our efforts to reduce CO2 emissions were recognized by the Airports Council International (ACI)
when we received Airport Carbon Accreditation (ACA) Level 2. We will continue our efforts in collaboration with
airport businesses to reduce CO2 emissions.
* Airport Carbon Accreditation is an international evaluation and accreditation program/system to manage and reduce CO2 emissions
from airports. It is the only environmental accreditation program designed specifically for airports. ACA has four levels for carbon
management: Mapping (Level 1), Reduction (Level 2), Optimisation (Level 3), and Neutrality (Level 3+).

12

■ Promoting energy conservation
We are working to reduce CO2 emissions (and conserve energy) by developing a carbon management plan that
integrates all of our ongoing initiatives. It includes the creation of an organizational structure, reduction targets, andmedium and long term plans to limit CO2 emissions. Examples of our energy conservation measures at facilities
include boosting the efficiency of equipment and plants and improving the thermal insulation performance of buildings.
We are also undertaking efforts to optimize airport operations and visualize and analyze energy usage.
In fiscal 2016 we reduced annual CO2 emissions by approximately 320 tons through actions that included conversion to
LED lighting in terminal buildings and the Observation Hall (1820 units), upgrading to more efficient baggage
conveyor motors (22 units), improving the efficiency of power distribution units for airport lighting systems, andconversion to inverters for 37 kilowatts incineration center (Clean Center) intake fans. Meanwhile for construction in
Terminal 2 (international flights) which started operations on January 28, 2017, we aimed for energy conservation in
the entire building, including the use of LED lighting and light sensor controls, the installation of high-efficiency air
conditioning equipment, and improved thermal efficiency of multi-paned glass windows.
We will continue to work toward making further improvements in energy efficiency and a reduction in energy
consumption for the entire airport.

Note regarding fiscal 2016 energy consumption:
Facilities covered have changed due to the change to new management under Kansai Airports.
Thermal conversion coefficients for heating and cooling is from actual numbers by the Kansai International Airport Heating and Cooling Supply Co.

■ Reducing greenhouse gas emissions
CO2 emissions from activities at this airport came to 537,000 tons in fiscal 2016, an increase of approximately 2.0%
from the previous year. Total CO2 emissions from aircraft increased, but the CO2 emissions per landing and takeoff
cycle decreased due to an increase in the number of aircraft landing and takeoff cycles and an increase in the ratio ofsmall aircraft. Meanwhile, CO2 emissions per landing and takeoff cycle decreased for airport facilities managed by
Kansai Airports, and for airport facilities managed by airport businesses. This decrease is due in part toemission-reduction efforts, including the pursuit of energy conservation. The largest share of CO2 emissions is fromaircraft, at 75.7% of the total, followed by 14.4% from passenger terminals and other airport facilities.

Notes for graphs:
CO2 emission factors for procured electricity are calculated
from Kansai Electric Power Co. coefficients for each year. For
fiscal 2016 the thermal conversion coefficient for heating andcooling is from actual numbers from the Kansai International
Airport Heating and Cooling Supply Co.
Note also that when the environmental plan was adopted, theintention was to use 2006 emission factors each fiscal year, but
it was later decided to use specific emission factors for eachyear in order to more closely reflect actual conditions.

Emission calculations:・Emissions from aircraft are calculated to include the airport-related
portion of the aircraft landing/takeoff (LTO) cycle as defined by theInternational Civil Aviation Organization (ICAO) (i.e., movement of
the aircraft between an altitude of 3,000 feet and the ground for bothlanding and take-off).
・Emissions from vehicles are from vehicles operating within the
airport’s restricted areas, and exclude trains, ships, and vehicles
travelling to and from the airport.

■ Promoting the use of ground power units (GPUs) (Note 6, p. 34)
The electricity required by stationary aircraft
to run air conditioning and other systems is
usually provided by an onboard auxiliary
power unit (APU).
To reduce air pollution from APUs, we haveinstalled ground power units (GPUs) toprovide electricity and air conditioning toaircraft parking spots and ask airlines at KIX
to use them.
KIX was the first in Japan to have changes
made to the Aeronautical Information
Publications (Note 7, p. 34) pertaining to
GPU usage starting in January 2010,

Note: Graph indicates the ratio of actual number of times(flights) GPUs were provided compared to number ofopportunities (flights). The calculations for 2012 onward
exclude low-cost carrier (LCC) airlines, which haveshorter aircraft parking times.

reducing the period of time an aircraft canuse its APU—from 30 minutes prior toscheduled departure, to just 15 minutes.
In fiscal 2016 the overall ratio of GPU
usage (including mobile units) was 78.9%.

Benefits of ground power units at KIX
CO2 emissions reduced (FY2016) by GPUs:

47,000 tons
Note: Reduction is calculated as the difference
between CO2 emissions from GPU use and theemissions that would have occurred if only
APUs were used.
Airlines with 100% GPU usage in fiscal 2016
(including the use of other companies’ mobile GPUs)
The following four airlines had a GPU usage ratio of 100% in fiscal 2016 (used GPU for all 12 months of the fiscal year):
Air France, Emirates, Hawaiian Airlines, Xiamen Airlines.

15

■ Idling prevention awareness campaigns
The Smart Island Council conducts an idling prevention campaign in June each year during national
Environment Month, designated by the Ministry of the Environment. This is an annual activity to raise
environmental awareness of airport users and businesses and encourage them to help protect theenvironment. The campaign (conducted June 3, 2016) involves handing out flyers and traditional
Japanese fans (uchiwa) with messages urging drivers of trucks, limousine buses, taxis and passenger
cars who use the airport to cooperate in idling prevention. A reduction of ten minutes of idling per tripby large vehicles (trucks, buses, etc.) arriving at the airport could reduce CO2 emissions byapproximately 570 tons annually (equivalent to the CO2 absorbed by 65,000 40-year-old cedar trees). At
the end of the campaign each year, volunteers also do a cleanup activity of loading and parking areas at
the airport.

Scenes of the idling prevention campaign asking drivers to cooperate16■ Introduction of eco-cars
We are making an effort to gradually introduce eco-cars (electric, fuel cell, compressed natural gas,hybrid, plug-in hybrid, and ultra-fuel-efficient vehicles) when vehicles are being replaced and otheropportunities arise. We are also encouraging businesses and operators on the airport island to make theshift to eco-cars. Eco-cars account for 402 of the vehicles authorized to operate inside the restricted
areas (Note 8, page 34) at the KIX airport; 192 of them are electric vehicles. (Eco-cars are 22.4% of total
fleet.)

2017

Note: Ultra-fuel-efficient vehicles meet the following emission and fuel efficiency standards.
1. Gasoline vehicles
2. Diesel vehicles
Emissions: 75% below Japan’s 2005 standards
Emissions: Meet post new long-term standards
Fuel efficiency: Meet/exceed 2015 standards or 25% of

2010 standards● Electric vehicle charging stations
Two rapid charging stations have been installed for electric vehicles (EVs) at the Observation Hall parking lot andParking Lot 5 at Terminal 2 (P5). Parkades P1 and P2 have regular chargers (plug-in type), with installations in April
2016 bringing the total in parking lots to 8 stations. Combined with others at that Kansai International Airport the total
is now 10 EV charging stations, making it easier for users to come by electric vehicle to the airport with confidence ofbeing able to get a charge. (Available in Observation Hall parkade 8 am to 10 pm, elsewhere 24 hours a day.)EV regular charger in parkade

● Kansai International Airport Taxi Operators Council

The taxi industry is also making an effort to switch to eco-friendly vehicles to realize a low-carbon
society. The Kansai International Airport Taxi Operators Council has introduced 22 hybrid cars, or about
39% of the total fleet of 56 vehicles.

■ Expanding the use of clean energy● Solar power

The KIX Megasolar system began generating electricity in February 2014 from photovoltaic panels
installed on the ground on the Phase 2 airport island and on freight building roofs, and a new megasolar
system also started operating in the Phase 1 international freight zone in September 2015. In March
2016, Nankai Bus Co. also started operation of photovoltaic panels installed on the roof of its building in
the domestic freight zone. All of this clean power generation produced the equivalent of about 9.7% of
the total electricity consumed at Kansai Airport. The system generated about 17.66 million
kilowatt-hours of electricity in fiscal 2016, reducing CO2 emissions by about 8,707 tons.

KIX Megasolar

Solar panels on roof of Nankai Bus building●Wind power

Since fiscal 2013 KIX Sora Park has had three outdoor street lights powered by wind turbines and solar
panels. In fiscal 2016 they generated about 150 kilowatt-hours of electricity, contributing to energy
conservation.
Also, a 5-kilowatt small wind turbine that was installed as a symbol of the KIX Smart Island Vision andstarted trial operation in September 2014 as a model case, the first of its kind at an airport in Japan. Two
additional turbines of the same size started operating in February 2015, bringing the total to three. In
fiscal 2016 annual output of these units was about 5,300 kilowatt-hours of electricity. The power
generated is being used to power streetlights in the Sora Park.

●Hydrogen energy
Trial use of hydrogen fuel cell vehicles
Hydrogen is the ultimate clean energy, with water as its only product of combustion, and it is valued for its potential inpreventing climate change. A hydrogen fueling station was installed at KIX in May 2007, fueling commercial vehicles
running on hydrogen-powered engines. Between October 2012 and March 2014, buses powered by hydrogen fuel cells
were in trial operation as shuttle buses between the Aeroplaza and Terminal 2. Meanwhile, we added the Toyota Mirai
to our vehicle fleet in April 2016, the world's first commercially-available hydrogen fuel cell vehicle (FCV), and we
added the Honda Clarity fuel cell vehicle in December 2016.
In January 2016, a large hydrogen fueling station was installed on the Phase 2 airport island as part of our Hydrogen
Grid Project. This was the first commercial hydrogen fueling station at any airport in Japan, and is also one of thelargest. Besides providing refueling for FCVs, this station also will be able to serve fuel cell buses such as those that
operate as limousine buses from Osaka International Airport, and as shuttle buses at Kansai International Airport.

Mirai and Honda Clarity）

Large hydrogen station (on Phase 2 Island)

Trial operation of fuel cell forklift and hydrogen infrastructure: A first among Asian airports
On May 20, 2014, we made the full launch of the Hydrogen Grid Project, and in February 2015 we started trial
operation of fuel cell-powered forklifts in the international freight zone of the airport, all a part of the Fuel Cell Forklift
Practical Application and Development/Testing of Optimal Hydrogen Infrastructure Improvements Project, selected by
the Ministry of the Environment for implementation. This is the first forklift of its kind to be used at any airport in Asia.
In April 2017, construction of tanks and high pressure piping for liquid hydrogen was completed in the international
freight zone as part of Japan’s first hydrogen infrastructure installation for industrial vehicles, and the country's largest
trial operations were launched for fuel cell forklifts and hydrogen infrastructure. The introduction of fuel cell forklifts
to handle air freight 24 hours a day can reduce CO2 emissions compared to forklifts powered by fossil fuels andelectricity. Also, the ability to refill hydrogen in under three minutes eliminates the work of charging and battery
exchanges and makes it possible to work with fewer interruptions, with benefits for work efficiency and scope of work.

20(3) An airport that recycles resources
We are working to ensure proper management of waste generated on the airport island, including
efforts through recycling and the reduction of waste volume. By using reclaimed water, we are also
promoting the efficient use of water resources.

■ Waste reduction and recycling
The more than approximately
11,000 tons of general waste
generated at KIX each year comemainly from sources such as
aircraft, airline catering plants,
and passenger terminal buildings.
In order to recycle and reduce
this volume of general waste, wehave written rules for waste
separationin“Regulations
Governing the Use of Waste
Processing Facilities” and have reached out to businesses operating at the airport, urging them to sorttheir waste. The result is a slight increase of waste generated at the airport in fiscal 2016, but the amountper passenger has declined, and the recycling ratio was 13.6% for general waste (an increase of 0.4%
over the previous year).
As for industrial waste, we have been encouraging businesses operating at the airport to makeefforts to manage waste properly, avoid creating waste, and recycle.

Efforts of airport island businesses to reduce waste generated
Japanese domestic airlines: About one-sixth of the total amount of waste generated at KIX comes fromaircraft. Recognizing the need to reduce waste by sorting it and reducing its volume, airlines including JAL
and ANA sort garbage coming from the aircraft passenger cabins. They are also separating used newspapers
from aircraft cabins. A large quantity of packing material (plastic) is used in air cargo operations to prevent
leakage, etc., and an effort is being made to recycle rather than treat it as waste.

21

■ Reducing clean water usage, using reclaimed water
On the KIX airport island, reclaimed water from airport facilities is purified at the wastewater treatment
center and used for flush toilets and for watering plants, as well as for cleaning roads and other groundsurfaces. In fiscal 2016, a total of 743,000 cubic meters of water was supplied to the airport (equivalent
to 4.2 cubic meters per landing and takeoff cycle). We used 517,000 cubic meters of reclaimed water,and our water recycling rate was 58.6%.

22

● Efforts to reduce water consumption
The Nankai Bus Co. has installed water-saving bus washing equipment at its facilities on the airport island. Also, thecompany has installed wastewater filtering and recirculation system to re-use wastewater, which is reducing theconsumption of clean water.

23

(4) An airport that respects biodiversity
Seaweed beds have been planted to help create marine habitat in Osaka Bay and we have beenmonitoring growth. An effort was made to provide better growing conditions for seaweed byinstalling special blocks on the sloping rock-fill seawalls built for the Phase 2 airport island
construction, and a number of other approaches were attempted, including seaweed seeding. We
have been creating seaweed habitat for about seven years near the Phase 1 island, and about three
years near the Phase 2 island. Also, by our efforts to promote greenery on the island, including
ceremonial tree plantings and the expansion of flower spots, we are working to restore and protect
coastal flora.

■ Protecting and restoring seaweed habitat, coastal flora
Encouraged by the results of monitoring the Phase 1 airport island seawall, KIX installed 3,200
seaweed-growing blocks (specially developed for this purpose) at five locations along the Phase 2
airport island seawall. To foster the quick formation of seaweed beds, seedlings were supplied by theplacement of spore bags containing species such as Sargassum filicinum (shidamoku in Japanese) andEisenia bicyclis (kajime in Japanese).
In addition, the transfer of 18 seaweed reef
blocks with significant Eisenia bicyclis
growth from the Phase 1 airport island
seawall in March 2002 to six locations near
the Phase 2 island provided a stable supply of
seedlings for the core seaweed bed.
A survey in March 2016 found that as a resultof these seaweed projects, the total area of
seaweed beds around the Phase 1 and Phase
2 airport islands amounted to about 53
hectares, and wakame seaweed distribution
was as shown in the figure below. Recent
studies have found kajime to be
declining, so transplanting and othernew efforts are being made to care forand maintain the seaweed beds.

Note: Reference to “seeding by spore bags” refers to an
initiative to actively supply spores by placing net bags
(spore bags) into the sea containing large mature
seaweed blades.

We have planted "flower spots" in various locations on the airport island with seasonal flowers, with the help of theSmart Island Council. Aiming to preserve landscapes and create spaces of rest and restoration on the airport island, we
are working to improve and expand the flower spots.

● Coastal vegetation: Restoration/protection

On the Phase 2 airport island, we have created areas for plants such as Dianthus japonicus Thunb.
(“hamanadeshiko” in Japanese), Lysimachia mauritiana Lam. (“hamabossu”), Calystegia soldanella(“hamahirugao”) and Vitex rotundifolia (“hamagou”) in order to restore and protect shoreline vegetationof the Osaka Bay area.

■ Scenic improvement projects●Green space at KIX Sora ParkKIX Sora Park is a large grassy green park near
Terminal 2 where people can relax and enjoy picnics
while watching aircraft take off and land. The Sora Farm
uses compost from grass clippings from Osaka
International Airport. Jogging and walking courses are
lined by sakura cherry trees along the inner waters of the
airport island. At the annual Dragon Boat Festival on the
inner waters, teams from Japan and around the world
join in heated competitions, with the international airport
as a backdrop.

●“Zero Garbage” clean-up activities
Outdoor clean-up activities are conducted around Japan on “Zero Garbage Day,” May 30 each year. After our Idling
Prevention Campaign we organized a “Zero Garbage” campaign at KIX from May 30 to June 13, involving clean-up
activities by KIX Smart Island Council member businesses that have ten or more employees.

(5) An airport that respects the local community
We have cooperated with others to boost interactions with local communities, and have beenpleased to have many people come to the airport island for events and attractions that create
interest and excitement about KIX. To promote good relations, since fiscal 2002 we have been
providing guest speakers and offering airport tours to introduce participants to the various kindsof work done at the airport.
We provide environment-related information via an environmental section on the KIX website.
The Kansai International Airport Environmental Center in the Observation Hall is designed forcommunication with local communities, including a variety of environmental information. We willcontinue our efforts to convey information to appeal to various audiences.

■ Provision of environmental information
Environmental information about KIX operations and projects is available on a
dedicated section of our website, which carries environmental monitoring resultsfrom airport operations, environmental reports, and environment-related events.
The monitoring results are also available at our Environmental Center.
We have installed monitors in the terminal buildings and Observation Hall publicarea to display the status of electricity generation by photovoltaic panels (KIX
Megasolar). The public can view information such as electricity generated to date,
CO2 emissions reduced, and the current sunlight intensity.

Visual displays ofenvironmental information■ Opportunities for environmental education
Environmental Center
The Environmental Center located in the second floor entrance hallof the Sky View Kansai Airport Observation Hall has display panels
about the airport’s environmental initiatives. In April 2012, welaunched the “Professor KIXeco” quiz system, which lets users have
fun while learning environmental information. People can also
experience actual sound levels, and see how independent agencies
conduct noise analysis.

27

■ Dialogue with local communities● Family Eco Classes
To raise awareness of environmental initiatives at KansaiInternational Airport, we offered hands-on "KIX Family
Eco-Classes: Hydrogen/Magnesium Air Fuel Cells" for higher andmiddle-year elementary school kids to learn eco-friendly topics ina fun way. Forty parent-child groups participated this year. On thetheme of clean energy, Iwatani Corporation presented half onhydrogen and fuel cell design, and Furukawa Battery presented thesecond half on magnesium air fuel cells. Participants enjoyedlearning about science and the environment.
● School speakers, eco-education at KIX Sora Farm
We offer guest speakers for local elementary schools andairport tours for older students of elementary schools to learn
about aircraft and the Kansai International Airport. In fiscal
2016, 589 students from 11 schools participated. As an airportthat recycles resources and respects the community, we held apotato-harvesting event for 80 local elementary school kids at
the KIX Sora Farm, an eco-farm that grows crops with organic
compost (Itami Airport No. 2 brand) made from grassclippings from Osaka International Airport.
● Kansai Airports Ekiden (relay marathon)
The first Kansai Airports Ekiden marathon was held on Saturday,
November 26, 2016. Fifty-nine six-person teams (354 runners)
ran along a special route through the green park. Participants
applied through businesses operating at KIX and ITM.
● EcoPro 2016 exhibit
We presented an airports booth exhibit at the2016

EcoProInternational

Exhibitionon

Environment and Energy at the Tokyo Big Site.
The event lasted three days starting December 8
and attracted 167,000 visitors. We featured ourvarious environmental initiatives, including the
Kansai Airports Hydrogen Grid Project, KIX
efforts to grow seaweed beds, and the use of
runway grass clippings at ITM.

28

■ Cooperation with businesses at the airport● KIX Smart Island Council initiatives
The KIX Smart Island Council was established as a body for
Kansai Airports, operators and businesses at the KansaiInternational Airport to work together on common objectives,
including environmental protection and improvements. With 48
business members, the Council conducts activities such as thevehicle Idling Prevention Campaign, the Garbage Zero
Campaign, Flower Spot plantings, and Good Practices
presentations. With the slogan of “Eco Action KIX: Small
Actions Have Big Results,” the Council set a target of reducing
CO2 emissions from airport facilities and operations vehicles
by 5% (3,000 tons) between fiscal 2013 and 2017, and actions
included reducing waste, promoting energy conservation, andintroducing eco-cars. The reduction target was surpassed early,
with a 6% reduction in emissions by the end of fiscal 2016, so
the Council is now planning further reduction efforts.

● Trainees from Asia
In March 2017, we welcomed trainees from Asia as part of acourse being offered by the Overseas Human Resources andIndustry Development Association (HIDA). We introduced
them to our environmental initiatives at the KansaiInternational Airport and took them on a tour of our wastewater
treatment center and other sites.

CO2 emission reductions by airport businesses● Participation in Airports Council International (ACI)
Kansai Airports is a member of Airports Council International, an organization representing 623 organizations thatmanage 1,940 airports in 176 countries and regions around the world (as of January 2017), and a member of the ACI
Asia-Pacific Regional Environment Committee. The seventh meeting of this committee was held in Dubai, UAE, in
October 2016 to discuss airport environmental actions.

6. Environmental performance data: (1) Environmental accounting● Environmental accounting
Since fiscal 2002, we have been developing an environmental accounting system to evaluate the costs and benefits ofour environmental initiatives, in order to further enhance their effectiveness and efficiency.
The greatest cost for environmental protection would be the cost of building the airport on an artificial island fivekilometers off the coast of the Senshu area to reduce the impacts of aircraft noise. However, as no methodology has yet
been well-established to quantify the environmental benefits of reducing noise, our accounting efforts have focused on
categories for which quantitative methods do exist, such as wastewater treatment and waste management.
/Accounting method◆Scope of accounting:
Airport operator◆Accounting period:
April 1, 2016, to March 31, 2017
◆Environmental cost categories: Based on “Environmental Accounting Guidelines 2005” (Ministry of the Environment), considering
specific conditions of the airport operator.
◆Environmental cost details:- Business area cost – Land costs related to incineration plant and sewage treatment plant; facilities
costs; maintenance/facilities costs related to energy and water-conservation; other maintenance costs- Administrative costs – Environment-related social contribution costs, environmental studies

The total environmental protection costs in fiscal
2016 amounted to 5.4 billion yen.
To calculate environmental benefits (based on
physical quantities) for the wastewater treatment
plant we chose total nitrogen (T-N) as arepresentative indicator for water quality andreduction of the pollution load flowing into Osaka
Bay. For the incineration plant, as a representative
indicator of environmental benefits we selected
NOx from waste incineration from among other air
pollutants. We then calculated the quantity of
reduced environmental loads from the difference
between legislated/regulatory standards and actual
emission quantities, and attempted converting thisto a monetary measure using an integrated
coefficient based on LIME (see Note). The
resulting environmental benefits (based on physicalquantities) came to 12 million yen.
We estimated cost savings from environmental
initiatives to be 794 million yen.
Note: “Life cycle impact assessment Method basedon Endpoint modeling.” A methodology tointegrate multiple environmental indicators into
one in order to evaluate environmental benefits.

□ Notes
1. Lden (day-evening-night equivalent level)
An indicator for measurement for environmental quality standards to measure aircraft noise, in use since fiscal 2013. Units
are in decibels (dB). (Previous indicator was WECPNL.) Under the environmental quality standards, a maximum Lden 57 dB(WECPNL 70) applies to exclusively residential areas, and a maximum of Lden 62 dB (WECPNL 75) applies to other areas
where normal living conditions need to be protected.
2. Transitioning to quieter aircraft
KIX made an effort to move toward quieter aircraft by instituting a complete ban starting in April 2002 on flights by any
aircraft not complying with Chapter III of the Convention on International Civil Aviation, Annex 16 (Environmental
Protection) on aircraft noise standards of the International Civil Aviation Organization (ICAO).
3. Quieter flight procedures
Noise-reducing flight procedures for aircraft, including delayed use of flaps and delayed deployment of landing gear on
approach to the runway.
4. Continuous descent operations (CDO)
A method of aircraft flight during descent, maintaining the minimum engine thrust for optimal descent (not horizontal flight)
until the aircraft reaches the starting point for instrument landing. Benefits of the method include reduced fuel consumption
and reduced CO2 emissions.
5. Air heater used to prevent white smoke
An air heater is used to reduce moisture content in emissions by introducing heated air into the flow, to ensure that whitesmoke being emitted from exhaust stacks does not reduce visibility for aircraft or the control tower.
6. GPU (ground power unit)
Stationary or mobile equipment/facilities that supply air conditioning or electricity to parked aircraft. The use of GPUs can
reduce the amount of fuel consumption by aircraft onboard auxiliary power units (APUs).
7. AIP
Aeronautical Information Publications (AIP) contain essential information for aircraft operation. In Japan they are compiledby the Civil Aviation Bureau (Ministry of Land, Infrastructure, Transport and Tourism).
8. Restricted areas
Runways and other landing/takeoff areas, taxiways, aprons, and other areas where entry has been restricted by signage.
Note: Numbers are rounded in all graphs.
