1. Basic policies of the ITM Environmental Plan
■Eco-Airport
An eco-airport can be defined as an airport that implements measures to protect the environment and create agood environment at the airport and in the surrounding region. In concrete terms, such measures can include
conserving energy (reducing CO2 emissions) and water, reducing waste, and taking other environmental
measures in region of the airport.

■Outline of ITM Environmental Plan
Osaka International Airport established the ITM
Eco-Airport Council based on the eco-friendly
airport concept, with airport-related partners as its
members. The Council produced the ITM
Environmental Plan in March 2007 and revised it
in March 2012. The Plan covers items such as thecurrent status of each environmental parameter,
environmental targets, and concrete measures, andaims include conserving water and energy(reducing CO2 emissions), reducing waste at the
airport, etc.

Outline of ITM Environmental Plan Adopted: FY2006
 Target activities: All activities at the airport, including
people, aircraft, vehicles, monorails, facility operations, etc.

 Area covered: ITM airport and region
 Environmental parameters: Air, energy, noise, water, soil,
waste, natural environment, etc.

 Assessment and reporting: An Environmental Report isreleased yearly, covering Plan implementation status andassessments.

■ Measures by ITM in the surrounding region
For years, ITM has been taking steps to reduce aircraft noise in the region around the airport and be “anairport that respects the local community,” including identifying noise sources and reducing the impacts ofnoise. These measures include soundproofing upgrades for housing, projects to expand greenspace,monitoring and reporting of data on aircraft noise, and more.
■Evolution of ITM Environmental Plan
In July 2012, Kansai International Airport (KIX) and Osaka International Airport (ITM) were integrated,
and a decision was also made to integrate their eco-airport policies. As part of efforts to make KIX an
eco-airport, the airport developed its third Environmental Plan. It covers environmental measures that can be
implemented sustainably as an “environmentally-advanced airport.” The Environmental Plan includes
measures and environmental targets built upon the five basic policies shown below.

management structure
注） ＊は他の取組方針と重複する施策であることを示す。

To implement the Eco-Airport Plan, the Osaka International Airport Eco-Airport Council was created, with
the Osaka Civil Aviation Bureau (Ministry of Land, Infrastructure, Transport and Tourism), airline
companies, and other airport businesses. Its function is to establish environmental targets and promote
environmental activities in a unified way. The environmental management is structured as shown below.

43．Environmental initiatives (1) An airport that respects the local environment

Reducing aircraft noise

ITM implements various measures to reduce aircraft noise, including restricting the number of aircraft
movements and hours of operation time, as well as encouraging the use of quieter aircraft, establishingflight routines that mitigate noise impacts, and constantly monitoring aircraft noise.
■ Measures at noise sources(Restricting flight movements and hoursof operation)
ITM restricts aircraft movements(landing-takeoff cycles) to 370 per day, in
consideration of noise and other aircraft
impacts on the airport region, and startingin the 2015 summer schedule, the shift
was made toward quieter propeller aircraft,with 200 slots for jets versus 170 for
low-noise aircraft, increasing convenience.
We are appealing to airline companies tointroduce low-noise aircraft to make useof these slots. Airport operation is 14 hours per day, from 7 a.m. to 9 p.m., and we strive to keep operations
within those hours, in cooperation with airline companies.
5

Encouraging the use of quieter aircraft
Osaka International Airport promotes the introduction of low-noise aircraft through a unique landing fee
system, with discounts for low-noise aircraft and surcharges for high-noise aircraft, based on actual noiselevels measured around the airport.
Optimizing runway use
It is normally preferred to have aircraft take off and land into the wind, but to reduce the impacts of aircraft
noise on the ground, operations at ITM are normally conducted on Runway 32 as shown below as long
conditions are safe (see image for flight direction).

6

Noise abatement flight procedures
As shown in the graphic below, we also make an effort to mitigate the impacts of aircraft noise byadopting noise abatement flight procedures.

Noise reduction at the airport○ Noise reduction measures during
aircraft engine testing
To reduce the impacts of noise
emitted during aircraft engine testing,a large sound-blocking wall was
installed at the engine testing site, andrules are in place for the location(within sound-blocking facilities),
timing, and methods of testing.

■ Aircraft engine testing site
The noise blocking effect reduces the noise level of a B747-400 (take-off
power) to below 65 dB in the vicinity of the airport.

7

○ Promoting use of GPUs and limiting use of APUs
In order to reduce noise impacts from auxiliary power units (APUs) while aircraft are parked, we arepromoting the use of ground power units (GPUs).
■ GPU usage status
GPUs supply electricity and air conditioning.
(Photo: GPU in use at ITM. Electricity isprovided as soon as aircraft arrives.)
E.g., in the case of a Boeing 777, an APU at a
distance of 20 meters has noise level of 92 dBA,
while a GPU is not audible even at a distance of one
meter.
Source: AGP Corp.
(http://www.agpgroup.co.jp/agp/airport.html)○ Other measures to reduce noise
Besides aircraft being a noise source, noise is also emitted from ground support equipment (GSE) vehicles.
We are working to reduce noise levels at the airport by introducing low-noise equipment such as electricvehicles and electric-powered forklifts.

Measurement and monitoring of aircraft noise
To monitor aircraft noise, ITM conducts continuous monitoring of noise levels at 10 locations in the
airport region, and releases the results publicly.

8■ Improving airport design
We have installed noise barrier walls and built noise barrier berms around the airport to mitigate noise
impacts from aircraft on the runway, etc.

■ Measures in the region of the airport
Kansai Airports implements the following measures around the airport to reduce the noise in the region of
Osaka International Airport and improve the living environment. Relocation compensation is applied toareas significantly affected by aircraft noise (Class 2 and 3 areas), and land obtained through this means isused to build parks and green space, in an effort to mitigate noise impacts. In Class 1 areas and their vicinity,
upgrades are provided to make housing more sound proof.

Relocation compensation programs
For buildings and land located in a zone when it is designated a Class 2 area, the airport has a program toprovide compensation for buildings and purchase the land based on an owner’s request to relocate outside
the Class 2 area.

9

Utilization of land acquired by compensated relocation program
To prevent new negative impacts of aircraft noise in Class 3 zones around the airport and improve theliving environment in the area, we create green spaces as buffer zones (see photos below) between the
airport and surrounding areas, through landscaping and planting of vegetation in areas obtained throughour relocation compensation program.
With the progress of the relocation compensation program in Class 2 and 3 zones, 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 in a planned andintegrated way, by having Class 2 and 3 zones and surrounding areas designated as green space, as defined
under the nation's City Planning Act. Examples include the Itami Sora Park on the Hyogo Prefecture sideand Fureai Ryokichi (public green space) on the Osaka Prefecture side of the airport.
Also, with the aims of letting local residents become familiar with the airport through greenery andpositive experiences as well as contributing to disaster prevention in the region, the Air Front Oasis
Shimogawara was designed to improve the living environment for local residents and also have disasterprevention features included in the green space, and adjacent to this, Itami City developed the
Shimogawara Green Area (photos on next page).

Green buffer zones

Itami Sky Park
This green space opened in 2008 as a place of relaxation for the local community and is also designed to serve
as a refuge area in time of disaster.

Fureai Ryokuchi (Friendship Green Square) in Toyonaka City
This is green space for use by the local community, designed with public input, with sports and recreational
facilities. It includes biotopes (see page 23), a multi-purpose square, tennis courts, heated swimming pool,grass areas, a playing field, and more.

Air Front Oasis Shimogawara and Shimogawara Green Area
Air Front Oasis Shimogawara is well-located with a view of Osaka International Airport. Its main feature isan observation deck with a commanding view of the daily activities at the airport, but it also includes amonument to the wind and other items with an aeronautical motif. Together with the Shimogawara Green
Area provided by Itami City, it is a place for locals to relax and enjoy the play and athletic equipment, and rest
area.

Mobile health checkups

OutlineTo promote the good health of residents living near the airport,
mobile health checkups are offered, particularly for people wholive in areas with greater amounts of aircraft noise.

Environmental

In order to improve the living environment around the airport, thisimprovements inprogram offers subsidies for efforts of the surrounding local

surrounding areas

governments, to improve noise-measuring equipment, parks, andlocal facilities, improve convenience, revitalize the area, and otheractivities.

Modifying and leasing sites acquired by compensated relocation program
In addition to the programs described above, based on the Osaka International Airport Regional
Improvement Plan established by the governors of Osaka and Hyogo prefectures, in order to effectively
utilize sites after residents have relocated elsewhere in compensated relocation programs, we modify andlease the sites as commercial facilities or parking lots, etc., as their uses are less likely to be affected byaircraft noise. In doing this we also consider the living environment around the airport.

12Conserving air quality■ Converting building boilers to gas
In November 2011, we converted boilers in the terminal building from heating oil A to gas. This contributes
to air quality conservation by reducing emissions of hazardous substances generated from burning heavy oil.
● Gas-fired hot water boiler
Boilers are being converted from heavy heating oil (containing sulfur, other pollutants), reducing air pollution.

Conserving water quality■ Conversion to eco-friendly snow-melting agentsIn the past, ITM used urea-based snow-melting agents, but large runoff of this agent could lead toeutrophication of water bodies. We have therefore switched to acetate-based snow melting agents, which are
expected to have lower impacts on water quality.
■ Reducing consumption of anti-icing and deicing fluid
The consumption of anti-icing and deicing fluid depends largely on weather conditions and fluctuates fromyear to year. Some operators have upgraded to better spraying equipment, boosting the efficiency ofspraying operations.

13

(2) An airport that respects the global environment
Osaka 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 to manage and reduce CO2 emissions fromairports. 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+).

Promoting energy conservation■ Introducing energy-saving equipment
ITM encourages all businesses and contractors aim for high energy efficiency, including the use ofenergy-saving types of lighting and air conditioning equipment.
● Escalators with motion sensors (passenger terminal, monorail station, and connecting bridge)
We have installed motion sensors to reduce electrical consumption at times and locations with fewer users.

● Lighting control based on light sensors (passenger terminal) Electricity consumption is reduced by outdoor sensors that automatically turn interior lights on when it is dark outside and off
when it is bright outside.

Control Control can be set to turnon in lighting conditions
between 5 and 300 Lx.

Mercury lights in building● Bicycle trailers (ANA) Eco-friendly hauling: Electric-powered bicycles are used to pull trailers.

● Heat-reflecting film on windows (passenger terminal) Heat-reflecting film on windows reflects sunlight and keeps temperatures down inside the terminal.

15

● LED lighting (south connecting bridge, north taxi stand) LEDs have a long service life, are efficient light sources, and use little electricity, reducing power consumption.
South connecting bridge

North taxi standON● Eco-friendly automatic door system (passenger terminal) Conventional automatic doors tend to slide open unnecessarily if a person simply walks past the door. We have installed
sensors that determine whether a person will walk past or through the door. This reduces unneeded door opening, saving
power consumption and reducing the load on interior air conditioning. Installed in all north-facing vestibules in the
North Terminal.

Automatic doors stay closed if someone walks past

Reducing greenhouse gas emissions■ Promoting the use of low-emission aircraftThanks to their high-performance engines and lower weight due to the use of composite materials, the latest
Boeing 787 aircraft are approximately 20% more fuel-efficient than other aircraft of similar size, resulting inapproximately 20% reduced greenhouse gas emissions. For other aircraft as well, airline companies aremaking an effort to use low-emission engines when acquiring new equipment.
■ Promoting GPU use, discouraging APU use
Carbon dioxide emissions can be significantly reduced if power and other services are provided to parked
aircraft by ground power unit (GPU) instead of an onboard auxiliary power unit (APU). GPU utilization at
ITM is on the rise. GPU hours utilized were about 4% higher in fiscal 2016 compared to 2011 when data
was first collected. Notably, CO2 emissions reduced through the use of GPUs amounted to 16,000 tons infiscal 2016.
●Use of GPUs
GPUs provide electrical power and air conditioning to parked aircraft (as depicted in photo below, taken at ITM).

As example of the significant benefits, a Boeing
777 emits 1,166 kg/hr of CO2 when using an
APU, but only 50.8 kg/hr with a GPU, resulting
in a large reduction in emissions.

Air conditioning

Power■ Vehicle idling prevention campaign
We are also helping to reduce CO2 emissions by reducing vehicle fuel consumption, through awarenesscampaigns to promote eco-friendly driving habits, including encouraging drivers not to idle their vehicle
engines while stopped. .
■ Promoting the use of public transportation
To promote the use of public transportation by our airport users, we offer connecting passengers freelimousine bus services between ITM and KIX airports, and work with public transportation companies toensure good long-distance bus services.

17

Promoting the use of eco-vehicles■ Introducing eco-vehicles for operations
Airports typically use many vehicles as ground support equipment (GSE) for aircraft operations, andtransporters (passenger vehicles) to move people around, so the use of “eco-cars” or eco-friendly vehicles
can help to reduce their CO2 emissions.
The adoption rate of eco-vehicles at ITM currently stands at 23.1% and it is gradually increasing.
Meanwhile, to promote the general use of electric vehicles, drivers need to have access to charging
equipment, so ITM has been installing charging stations in airport parking areas.
● Charging station for electric vehicles
Quick charging stations have been installed in ITM parking lots.

Promoting the use of clean energy■ Installing photovoltaic systems
ITM has installed photovoltaic systems (solar power generation) to promote the use of clean energy.
●Photovoltaic panels
Solar panels installed on roof of ITM administrative building18

(3) An airport that recycles resources

Zero emissions■Reducing and recycling waste as a resource
At ITM we are working to boost recycling rates and limit the amount of waste generated, by measures suchas proper waste separation, making use of grass clippings from runways (as animal feed and compost, asshown on next page), re-using office materials, and recovering resources from waste, etc.
● Waste is collected in separate bins for recycling, and different materials are handled separately
Separation of waste is an important step in recycling.

● Preparation before resource recovery (examples of deconstructing, breakdown and sorting)19

Initiatives as an eco-friendly, resource-recycling airport
・ Osaka International Airport produces about 1,126 tons of grass clippings annually from maintenancealong the runways.
→Clippings are composted and processed into organic fertilizer for reuse at ITM and local
elementary schools, etc.
→Clippings are also fermented to produce silage and reused as feed provided at no cost to livestock
farms and the Foundation for the Protection of Deer in Nara Park, etc.
・ The fertilizer from grass clippings has been registered by the Ministry of Agriculture, Forestry and
Fisheries as Itami Airport 1, 2, and 2K brands (October 25, 2015). This is first case of any Japanese
airport to achieve such recognition.

20

Conserving and recycling water■ Promoting water conservation
Businesses at ITM airport are promoting water conservation through various means, including the use of
automatic faucets in sinks for handwashing, and noise generators in women’s toilets that reduce the need toflush. Additional approaches include adjusting water pressure and flow rates of toilets and hand washingfaucets, using displays and notices, and applying stickers as reminders for users to conserve water.
■ Using rainwater
Some businesses at ITM are reducing clean water consumption by collecting rainwater for uses such as
sprinkling and watering (surfaces, plants, etc.).
● Rainwater storage tanks
Rainwater falling on airport facilities is captured, stored, and then pumped out for other uses. This helps to reduce theconsumption of clean water.

21

Other initiatives■ Donating retired equipment for other uses, grant assistanceKansai Airports donates retired airport fire trucks from Osaka International Airport for use indeveloping countries.

(4) An airport that respects biodiversity

Creating natural environments■Parks and green spaces near the airport
Around the airport there are parks and other areas that have been developed on vacant sites after residents
have relocated away under the relocation compensation program. One example is the Fureai Ryokuchi(Friendship Green Square), with its open area and biotope providing space for visitors to have contact withnature.

● Biotopes in the Fureai Ryokuchi These urban biotopes include water features to attract dragonflies and other living things.
 The flowing water, ponds, rocky banks, and aquatic plants support a diversity of habitats.

■Creating green space at the airport
Osaka International Airport has planted green areas and a “Flower Campus" on the roof of the passenger
terminal building. The planting of flower beds instead of grass helps reduce the need to cut grass and also
improves the scenery.

● Greenery at the airport (passenger
terminal building) Green roof on terminal building (upper left) helps
regulate temperature inside the building.
 Greenery on roof deck (upper right) creates
relaxation space and pleasant scenery.

 Green walls (left) can be found in many locations.

23

● Greening around buildings: “Flower Campus”
 Designs are developed by students of Osaka Prefectural Engei High School (specializing in horticulture), and teachers,
students and airport staff cooperate to manage the greenery. This activity was done once in fiscal 2016.

● Greening the airport (around buildings): “Butterfly
Garden”
 The school also helped to develop the “Butterfly Garden” as one type of“biotope.” It features plants that attract butterflies and other insects. To
celebrate the garden, the “ITM Airport Academy: Seminar on Insects”
was held once in fiscal 2016.

● Greening inside the airport terminal buildings
 We also install greenery in many places inside the terminal buildings, creating comforting spaces.

● Greening on the airport grounds
 We also have green rooftops of ITM administrative buildings to promote greenery and reduce CO2 emissions.

24

■ CO2 emissions (air parameter)
Annual carbon dioxide emissions were on a declining trend until fiscal 2009 from the reference year (fiscal
2001). They then have tended to increase, reaching 28,075 t-CO2 in fiscal 2016 (at approximately the samelevel as the reference year).
Emissions per passenger jumped in fiscal 2011, but thereafter have been level or decreasing slightly. The
jump was due to a major increase in the CO2 emission factor for electricity (due to nuclear power plants
being halted) and a reduction in passenger traffic, and these are likely a result of the Tohoku earthquake andtsunami in March 2011.
Airports typically consume a large amount of electricity, so CO2 emissions are significantly affected bychanges in CO2 emission factors (used to calculate emissions). For comparison, the graphs on the next page
show how emissions would have been calculated if the CO2 emission factor for electricity had remained thesame as when the ITM Environmental Plan was adopted. The graphs show total that CO2 emissions would
be on a declining trend since the reference year, reaching 21,903 t- CO2 in fiscal 2016 (a 34% reduction fromthe reference year).

31For comparison: Emissions as calculated using CO2 emission factor from year of
adoption of ITM Environmental Plan

Note: CO2 emission factors for the year the ITM Environmental Plan was adopted are from a report by the
Panel Committee on GHG Emission Calculation Methods (Ministry of the Environment, Japan, 2010).

■ Eco-friendly vehicle use (air parameter)
The penetration ratio of eco-friendly vehicles was increasing steadily from the reference year (fiscal 2001) tofiscal 2009, but has been generally steady since then.

Note: Eco-cars (or eco-friendly vehicles) here include natural gas, electric, hybrid, methanol, LPG (liquefied petroleumgas), fuel cell, and certified low-emission vehicles. Examples of the latter (certified low-emission) are vehicles certified ashaving achieved Japan's 2000 and 2005 vehicle emission standards.

32

■ Clean water use (water parameter)
The amount of clean water used in fiscal 2016 was about 88% below 2006 consumption, and about 63%
below 2001 (signifying a net average annual reduction of 1.2% since FY2006). Clean water consumption
per passenger in fiscal 2016 was about 73% below the level in 2001.

33

■The use of snow-melting agent and deicing/anti-icing fluid (soil parameter)
No snow-melting agent was used from fiscal 2006 fiscal 2011. It was used from fiscal 2012 onward, but
only acetic acid-based or formic acid-based snow-melting agents were used that have low impacts on water
quality. As for anti-icing/deicing fluid, general assessments are difficult as consumption is affected byweather (minimum temperatures at the Toyonaka weather station as used as the reference point), but also by
factors such as patterns of continuous low temperatures and hours of operation. The interpretation here isthat there have been no particular variations in the use of anti-icing/deicing fluid.

■Waste generation (waste parameter)
The amount of general waste (including grass clippings disposed as waste) increased temporarily but thendeclined steadily, and in fiscal 2016 was about 79% of the amount in the reference year (2001). Generalwaste (excluding grass clippings) has been declining steadily year by year. The graph shows the beneficial
impact of utilizing grass clippings effectively (to make animal feed and fertilizer) since fiscal 2010.

35

■Recycling rate of waste (waste parameter)
The recycling rate of general waste (excluding grass clippings) was slightly above 30% from fiscal 2006 to
2010, and over 35% from 2011 onward. The recycling rate of general waste including grass clippings
dropped temporarily below 30%, then increased as grass clippings started to be utilized more from 2011, andhas surpassed 40% since 2012. The recycling rate for industrial waste temporarily increased to 38% in 2012
but has generally fluctuated between 20% and 30%. Our environmental target for the industrial waste
recycling rate is 32%, so more effort is needed in this area.
Note: Our quantity of industrial waste generated fluctuates significantly from year to year, and the amountby sub-category can vary considerably, changing the relative proportion of that category in a given year.

36

■Use of public transportation (“other” parameter)
Transportation access to Osaka International Airport is highly convenient, and the use of public
transportation (monorail and bus in graph below) has been steady for many years, in the range of 70% to
80%.
