A Message from the Environment Supervisor

Desire to contribute tosustainable development
while providing a richer life for people.
Tell us about establishing new
mid- and long-term objectives.

How are you engaging in theactivities involved in production?

In regards to CO2 emissions, each country is setting new
objectives for 2020 and beyond in preparation for COP21.
Accordingly, Komatsu has also established new mid- andlong-term objectives for 2020 and 2030. In setting theseobjectives, we took into consideration not only CO2 , but our
products life cycle, including fuel consumption of products,
waste and water input as well as efficient use of resources.
When looking at CO2 in terms of lifecycle, it has been estimated that 90% of all emissions comes from construction
equipment products, making it clear the importance of reducing this amount. In addition, while aiming for further
growth in productivity, we have set even more aggressive
target values for CO2 emissions from production. We havealso set targets for waste and water input, in order to work
to w ards the e ff icient use o f re source s, no t only f or ourplants in Japan but for our plants all over the world.

The electricity reduction activities that started after theGreat East Japan Earthquake of 2011 are progressing tomeet the objectives set for 2015.
In 2014, we took a major step forward with the start-up of
Awazu s new assembly shop making groundbreaking configuration and high levels of energy conservation capabilities a reality, and with the use of biomass heat supply andelectric power generators being instituted at the Awazu
plant. Biomass handles both heat supply and electricity
generation, making overall high energy efficiency possible.
Also, the supply of timber for fuel is being co-producedwith the local forest industry, starting up a new activity
called local production for local consumption to make themost of the local specialty.
Of course, the basics of environmental activities such ascompliance to law , efficient use of resources and improvement of greening ratio are being consistently pursued as activities to be steadily maintained.

Tell us about CO2 reduction inconstruction equipment products.
In terms of how to reduce CO 2 emissions from construction equipment, we have developed products such as hybrid construction equipment that have excellent fuel efficiency. In 2015, our sphere of activity has been expanded
further to include the way in which construction equipment
is used, so that we can now offer the new solution SMARTCONSTRUCTION . This is a solution that provides an automated control of innovative work equipment, a revolutionary topographical survey technology, and a system called
KomConnect to connect data, in order to dramatically
improve efficiency on the work site through topographicalsurvey, design, construction management and use of highly advanced automated ICT construction equipment.
Based on this development, efficiency can be dramatically
improved, and CO 2 emissions from construction equipment will also be greatly reduced.

Komatsu will continue to contribute to sustained development while making life richer for people, through products
and solutions that have excellent environmental qualities
born of advanced technology, and through pursuing revolutionary efficiency at our production sites.

Komatsu s assessments of the CO2 emissions by Scopes 1, 2 and 3 reveal that CO2 emissions from the construction equipment being in use account for nearly 90% of the total amount of CO2 emissions produced throughout its lifecycle, from material procurement to manufacture, usage and disassembly (Refer to Amount of CO2 Emissions by Scope 3 on page14).
With this in mind, Komatsu has taken a three-step approach to cutting CO 2 emissions from its products.

Step 1
Step 2
Step 3

Reduce CO2 Emissions across Construction
Work Flow with Dantotsu Solutions( from computer-aided construction to Smart Construction)

Improve the fuel efficiency of construction equipment ( Dantotsu products)
Cut the fuel consumption of construction equipment through suggested usage improvements ( Dantotsu services)

Commitment to computer-aided construction

Drastically enhance construction efficiency and thereby reduce fuel consumption by using automatic
control on construction equipment ( Dantotsu solutions)

Computer-aided construction is a plan of activity in whichelectronic information on one out of a sequence of processes
relevant to the implementation of construction works-fromsurveying and designing, to constructing, testing, inspection
and management-that has been obtained using ICT (information and communications technology) is applied to other processes to ensure enhanced productivity, quality, etc. acrossthe process sequence.
Construction equipment loaded with a computer-aided construction system verifies operating equipment location information and 3D design data against each other to assist the operat or a t w or k a nd imple me n t a u t oma tic c on trols, the re b y
drastically saving previously required finishing stake work andsurveying work during construction, and the consequent corrections. The results are shorter construction periods, better
construction equipment availability and reduced CO2 emissions.
In 2013, Komatsu introduced the world s first ICT computer-aided construction bulldozer, the D61PXi-23-featuring an
automatic blade control capability-on the North American,
European and Japanese markets. Then in 2014, Komatsu introduced the world s first hydraulic excavator, PC210LCi-10,
featuring a semiautomatic control capability into the North
American and European markets and the PC200i-10 into theJapanese market. Komatsu expects that these flagship models will help computer-aided construction expand to a broader range of construction sites.
Both models carry a new-generation engine that greatly reduces Nitrogen Oxide (NOx ) and Particulate Matter (PM)emissions to address new emissions regulations in effectsince 2014 in the U.S. and Europe.

Komatsu is broadening the scope of its approach to CO2 emissions reduction by offering solutions as well as products, and by providing innovative ways to cut CO 2 emissions to its customers.
CO2 emissions from products account fornearly 90% of the total amount of emissions

Lifecycle of Construction Equipment

Step 1
Reduce CO2 Emissions with
Dantotsu Product
Komatsu delivers fuel-efficient products to reduce CO2
emissions. Examples are the hybrid hydraulic excavatorslaunched into the global market for the first time in 2008,
which have reduced fuel consumption by 25% on the average when compared with other then-available models.

Step 3

Automatic stop control
When the blade edge of the bucket reaches the construction surface during boom or bucket operation, the operating
equipment stops automatically to avoid harming the construction surface. The blade edge is also easy to position.

Environmental Report Digest 2015

Step 2

Reduce CO2 Emissions from
Products with Dantotsu Services(KOMTRAX Usage)
In addition to improving fuel efficiency of products,
Komatsu advises its customers on how to use construction
equipment to reduce fuel consumption by offering them visualized presentations of equipment usage condition data.
A Komatsu-developed vehicle information management
system used to this end, KOMTRAX automatically collects
operating and health information from the construction vehicles in use around the globe to aid in remote vehicle monitoring, management and analysis. Information collected is
not only made available to customers via the Internet but isused to visualize equipment operating hours and work
hours ,usage and fuel efficiencies, to come up with suggested improvements.
This is how Komatsu supports its customers in their effort
to improve fuel efficiencies (that is, reduce CO 2 emissions).

ICT construction equipment features

Ground leveling assistanceThe boom lifts automatically so that the bucket moves
along the construction surface when the arm is manipulated. This feature allows the operator to carry out rough excavation work without concern for the construction surface
and do the final finishing excavation work merely as a arm
lever operation. A boom lowering operation may be included to broaden the sphere of construction.

Environmental Report Digest 2015

On January 20, 2015, Komatsu unveiled its Smart Construction initiative in Japan.
To encourage wider usage of computer-aided construction by its customers, Komatsu proposes to make the work
flow on construction sites more efficient by measuring thecurrent terrain using drones and 3D scanners to prepare
3D drawings in the preconstruction processes in order tovisualize the work of planned construction processes
and the progress of planned activities with computer-aided
construction equipment. Komatsu expects that simplifying
construction processes and making the on-site workflow
more efficient can result in the secondary benefits of CO2
emissions reduction.
Furthermore, the entire sequences of construction processes can be compiled on electronic databases, making
the administrative work paperless to further reduce the environmental load.
I n i t s c o m m i t m e n t t o c o m p u t e r- a i d e d c o n s t r u c t i o n ,Komatsu is driving the global deployment of Smart Construction, including North America, Europe and Japan, notonly to compile information about construction equipmentused in construction processes on to databases, but toalso reduce the environmental load across all construction
works.

Acquiring ISO14001
Komatsu has implemented a Group-wide initiative to acquire
ISO14001 certification, an international standard for environmental management systems. The objective is to enhance management quality by strengthening systematic steps towards environmental conservation.
Since 1997, several manufacturing facilities both inside Japanand abroad received certification. In FY2005, the four plants belonging to Komatsu Ltd. (the parent company), the Awazu, Osaka, Mooka, and Oyama Plants, acquired integrated certification.
As the second step, in FY2007 Komatsu added its major affiliates
in Japan and yet-to-be-certified non-manufacturing facilities –notably the Head Office – to the above four plants, with integrated certification attained by the Group in Japan in May 2008.
Upon completing the March 2012 recertification, the KOMATSU Way Global Institute and Komatsu NTC Ltd. were included in
the integrated certification. The Group conducted the recertifica-tion qualification again in March
2015, and will continue to workon improving the quality of management in Japan.
Komatsu aims for 100% of
overseas production facilities toacquire certification by FY2015,
and in FY2013 Komatsu (Shandong) Construction Machinery
Corp. , Komatsu Manufacturing Rus. LLC , and Hensley
Lingfeng Co., Ltd (China) acquired certification, and in
FY2014 Cabtec (Thailand) acquired certification as well.

In 2014, although not a developing country, the affiliatedcompanies in the U.S. (KAC: 3 offices) and Brazil (KDB: 1
office) were visited for an inspection of their environmental
facilities and to exchange views on environmental preservation. All four offices were conducting appropriate energy
conservation activities, air and water quality measure ments, and sorting of waste, and no major environmental
risks were found.
Environmental inspections of overseas affiliated companies will continue to be carried out and the environmental
efforts of the entire Komatsu Group will continue to be improved.

Global Safety and Environmental Affairs Meeting (at the Komatsu Way Global Institute)

Setting New Mid- and Long-Term Objectives
In 2010, Komatsu set mid- and long-term objectives(2015, 2020) for the production department in regards to
CO 2 reduction and started reduction activities. While midand long-term objectives for CO 2 reduction is being set for
the world at the COP21 in 2015, Komatsu has reevaluatedits mid- and long-term objectives thus far (up to 2020) andset new mid- and long-term objectives up to 2030 in order
to contribute to the environmental change measures.
Among these objectives, the stringent objectives havebeen set increasingly in regard to CO 2 reduction particularly in domestic production, taking into consideration theelectricity situation after the Great Eastern Japan Earthquake of 2011. Also, in addition to the targets set for CO2
reduction, targets will also be determined in terms of production, for our domestic and overseas factories regarding
the amounts of waste generated and water input, in orderto promote the efficient use of resources.
In addition, mid- and long-term objectives up to 2030
were set for logistics CO 2 for the first time.
Further, in looking at CO 2 generated in the life cycle ofconstruction equipment products, we found that CO 2 emissions during construction equipment use makes up appoximately 90% of total emissions. Therefore, fuel efficiency
goals for construction equipment products were also set
this time, up to 2030, in order to promote CO 2 reduction
over the entire life cycle.

For 3 days, from November 5 through 7, 2014, the Sixth
Global Safety and Environmental Affairs Meeting was heldat the Komatsu Way Global Institute with the participationof 36 officers responsible for safety and environmental
management from 12 different countries.
It was a productive meeting that included an explanationof Komatsu s policies regarding the environment, as wellas time for officers from each manufacturing facility to divide into small discussion groups to exchange information.
It was decided that this meeting would be held annually
starting in 2015, to further the sharing of cases in Japan,
and facilitate the communication among participants, in order to promote environmental activities on a global scale.

Companies Association Chairman Award
Fiber Laser Cutting Machine KFL Series
The fiber laser cutting machine KFL series , marketed by
Komatsu Industries Corp. since 2013, was selected to receive the The Japan Machinery Companies Association
Chairman Award at the 2014 Excellent Energy Conserving
Machinery Awards.
This award program is sponsored by the Japan Machinery Companies Association and has been held annually
since 1980 for the purpose of promoting the developmentof energy conserving machinery, as well as popularizing
the use of excellent energy conserving machinery byawarding a person, companies and other organizations
which are recognized as contributing to promoting the efficient use of energy by developing and putting to practicaluse such excellent energy-saving machinery.
This is a laser-processing machine that aims to downsize the oscillating machine output while securing the productivity of sheet-metal processing for thin stainless steel
sheets. Because the processing speed of sheet metal is
proportionate to the energy density of the laser irradiating
the material, it is important to guide the oscillating beam tothe processing point without letting its quality deteriorate.
By directly connecting the process fiber running from thefeed fiber of the oscillator to the processing point, we developed a method to guide a high quality beam to the processing point in this machine. As a result, while securing
the same productivity level with 2kW output as the conventional type fiber 4kW, by downsizing the oscillator output,
the oscillator s energy consumption was decreased. Also,
by condensing the nitrogen gas in the air for use as incisiongas, the running cost at the sheet metal incision point was
reduced.

Initiatives to Mitigate Climate Change
in Business Operations

Halving Electricity Usage Project

Reducing CO 2 Emissions in Manufacturing
Operations
As part of our efforts to mitigate climate change, Komatsu has adopted an indicator of CO 2 emissions per unit ofmanufacturing value with respect to the amount of electricity, fuel gas, fuel oil, and other types of energy used in manufacturing operations, the company established more aggressive mid to long term objectives in FY2013.
In 2010, to contribute to Post Kyoto Protocol climatechange measures, a mid-term goal for 40% reduction compared to 1990 levels by 2015 was established but following
the start of activities to halve power consumption, activities are under way to achieve an ambitious 54% reduction
compared to FY2000 levels.
Energy-saving activities were undertaken through the establishment and start of high efficiency lines and removal ofold lines along with adopting renewable energy and horizontal expansion of various production improvements revolving around the Company-Wide Power Reduction Project Team established in May 2012. As a result, the index
for the CO 2 emissions per unit of manufacturing value was
reduced 36.9% compared to FY2000. CO 2 emissions at
Komatsu s overseas manufacturing sites have also beencut 33% compared to FY2005 as a result of fuel conversion
and lateral spread of typical improvements across domestic plants.
Komatsu will continue its effort into this fiscal year toachieve further reductions in the CO 2 emissions index by
renewing aged buildings of over 40 years with a buildingthat adopts the latest energy-saving technology and by
making steady efforts on-site.

In the overseas scene, the need for long-distance trucking in the U.S. has been cut as a result of cross-sourcing
North America-bound products from the CMO (Chattanooga, America) plant (with 44% of the total volume of North
America-bound products having been switched to imports
from the Osaka Plant in Japan and the BKC plant in Thailand).
Again, changes in the shipping destinations, coupledwith the improvement at the CMO, have cut the averageland trucking distance for overseas plants by 6%, with thebasic unit of overseas CO 2 emissions improving by 3.0%

Improving the Rate of Modal Shift in JapanThe rate of modal shift improved up to 29.1% in FY2014.
By making proactive use of coastal shipping in place oflong-distance trucking, which had increased since the outbreak of the Great East Japan Earthquake in 2011, the rateof coastal shipping has expanded.
The rate of railway transport advanced by 1.7% to reach
6.1% in FY2014 after a continual effort to expand it having
been pursued since FY2013 as a prioritized area of improvement.
Plants at which such effort was directed have gained a

Promoting Recycling
Promoting the Reman
Remanufacturing Business

Effective Utilization of Resourcesin Manufacturing Operations (Waste)

In our Reman business, the Komatsu Group remanufactures used engines, transmissions, and other key components (parts) of construction and mining equipment intoremanned components that have the same high quality
as newly manufactured components. We then put thesecomponents back on the market. The Group is promotingt h e R e m a n b u s i n e s s a t 1 2 R e m a n C e n t e r s a ro u n d t h eworld.

In tandem with reducing the amount of waste produced
during manufacturing operations, Komatsu engages in zero
emissions activities to use waste materials as resources.
Starting in FY2011, Komatsu set new medium-term goals forour recycling rate and for the amount of waste generated perunit, and we are working toward those goals. In an effort to attain zero emissions, Komatsu raised the target recycling rate
up to 99.5% or greater by FY2015. Then in FY2014, the recycling rate was 99.6%, making it the fourth year in a row toachieve the mid-term goal early. And Komatsu s mid-term goal
is to have an above 95% recycling rate in our overseas operations by FY2015, and is working towards effective re-use ofwaste accordingly.The recycling rate at Komatsu s overseas
manufacturing facilities picked up to 91.4% in FY2014.
Komatsu had projected cuts in the amount of waste materials generated per unit of manufacturing value in FY2015
of 20% or greater, compared to the FY2005 level. As a result of strict adherence to separated-waste collection andincreased conversion of waste materials to resources, theamount of waste materials generated per unit has been
trimmed by 42.7%, compared to the FY2005 level. Komatsu aims to continue its effective separated waste collection
policy to achieve its medium-term goals.

The Myanmar (KMM) Reman Center established in April 2015

Providing Reman-related Information
The Komatsu Group has set up Reman-Net as a network for Komatsu Reman Centers around the world. The
Group is actively using this network to develop Reman operations for reuse and recycling of components at the global level.
IC tags and two-dimensional bar codes are used to manage each item s remanufacturing history, and to track quality and durability information. This important information isreported to the Group, to help develop components with
optimal service life.

Future Steps
To further increase the reuse rate of used components,
the Komatsu Group is reducing the number of disposedparts by:● Developing parts for remanufacturing, oversized parts,etc● Developing recycling-related technologies (assessmentand measurement for reuse, remanufacturing worn-out
parts, cleaning, heat treatment, etc.)
to reduce waste components, and thereby further increase
reuse and recycling activities.

the Hokuriku District, which are major users of undergroundwater. The Company has achieved reductions in the amountof water used per unit of manufacturing by 63.3% comparedto the FY2005 level, through the reuse of water during processing and the elimination of wasteful day-to-day practices.
In particular, the Awazu Plant significantly reduced its
groundwater consumption through measures such as adjusting the pump discharge, reevaluating the temperature ofcooling water used for heat treatment, and the installationof water-circulation equipment. As a result, the Awazu Plant
was able to reduce water usage by more than 80% per unitof manufacturing value.
Komatsu will continue efforts to save water resources toachieve its medium-term goals.

Initiatives that Deal with Biodiversity
Komatsu will maintain our commitment to protecting biodiversity in our business activities, recognizing the impactof those activities on the ecosystem.

Practical Test Section of Development Division : Efforts
to Make the Most of Surrounding Nature
We conduct distribution studies of rare species on facility
grounds, maintain the Land of Fireflies as well as try to attract more fireflies.
We are also working on creating an environment friendly
to the habitation of living organisms by exterminating theGoldenrod, a foreign species, from the facility grounds andattempting the recovery of vegetation native to the district.

Promoting Legal Compliance, andPollution Mitigation and Prevention
Komatsu Group companies periodically report and archive
environmental measurement results, in accordance with applicable laws and regulations of national and local authorities. In FY2014, no major accidents or legal violations occurred that would threaten environmental contamination.

Addressing Soil and Groundwater Contamination

Constructed biotope

Oyama Plant : Social Contributions Making Use of Satoyama
At the biotope that was constructed within the Oyama
Plant, Biotope Satoyama (Komatsu Manabino Mori), we
participated in the Reconstruction Support Activity by cultivating Japanese black pine seedlings to be transplanted to
Fukushima prefecture.

Japanese black pine seedling cultivated at Satoyama

Komatsu has established guidelines for testing soil andgroundwater at our Japan facilities, and we perform investigations according to applicable laws and regulations atbusiness units that are to be sold, closed, or demolished. If
contamination is found, the Company takes appropriate
measures under the supervision of local authorities. We are
performing voluntary investigations at currently operating
business units to check for contamination from volatile organic compounds (VOC) from cleaning solvents that wereused in the past.
Komatsu has been surveying soil and groundwater for VOC
contamination at Group business units in Japan since 2005.
Business unit sites at which contamination has been detected have implemented countermeasures. The Company has
selected methods to clean up the sites as quickly as possible.
Work at the Oyama Plant was completed in FY2009. The
clean up work at the other sites are continuing.
In FY2013, change in land character notifications werefiled for the Awazu Plant, in accordance with the provisionof Article 4, Amended Soil Contamination Countermeasures Act. However, no survey order was issued from administrative authorities in relation to these sites because
there was no concern regarding possible contamination.
Going forward, along with driving the clean up activities,
we will monitor the site boundaries to make sure that offsite outflow of groundwater does not exceed the standards.

Initiatives that Deal with Biodiversity
With the establishment of Komatsu s Declaration of Biodiversity and Biodiversity Guideline in January 2011,
Komatsu business units worldwide began activities designed to preserve biodiversity.
Komatsu promotes initiatives to preserve biodiversity on
two levels.
First, the Company continues to promote ongoing efforts
to reduce the environmental impact of Komatsu s businessactivities. Komatsu also considers biodiversity when deciding how land is to be used, such as when building factories.
Second, Komatsu is becoming directly involved in thepreservation of biodiversity, and at the same time expanding our one-site, one-theme activities to raise employees awareness of the need to preserve local ecosystems.

Management of Chemical Substancesand Pollution Prevention
Reducing the amount of PRTR-related
substances
The number of substances covered by PRTR* with a handling volume of 1 ton or more (0.5 ton or more for Class I
Specified) in FY2014 has remained at 23, unchanged fromthe previous year. The handling volume (1 ton or more) has
been reduced about 10% from the previous year.
Among all PRTR-listed substances, the three substancesof xylene, ethyl benzene and toluene account for approximately 94% of the emissions from Komatsu and KomatsuGroup manufacturing facilities. Most of the emissions are
released into the atmosphere.
At domestic Komatsu group production facilities, initiatives, such as switching to paints with a lower proportion of
PRTR-listed substances, using high-solid paints, improving coating efficiency and reducing film thickness, are being undertaken for the continuous reduction of handlingvolumes. Also, substances handled in large volumes arebeing changed to secondary materials that contain chemical substances having less impact on the human body. The
amount of emissions in FY2014 has been reduced byabout 12% from the previous year.

Breakdown of the Amount of PRTR-related
Substances (Released and Transferred from

Komatsu has been making efforts from an early stage toreduce the use of asbestos, lead, and other substances ofenvironmental concern. In FY1999, Komatsu created its
own list of banned substances and substances approved
for use only in limited circumstances (Refer to Substancesof Environmental Concern Banned or to Be Reduced for
Use in Products ), which was based in part on the chemical
substances banned under Japan s Law Concerning the Examination and Regulation of Manufacture of Chemical Substances Control, as well as regulations in other countries.
In addition, Komatsu has begun comprehensive controlof substances of environmental concern. Recently, in compliance with REACH* 1 , Komatsu began revising its listing of
substances designated as approved for limited use, to be
reduced, and banned. Through the cooperation of suppliers, the Company has initiated a system to strengthen
control of substances of environmental concern in its products. This system has been deployed in Japan and Europe,and is also being implemented in other overseas subsidiaries.

Environmental impact* Refer to the Data on Environmental
Impact Resulting from Business
Activities for details on the methods
used to calculate amounts.
* Total emissions of waste are expressed
as a composite of the amount recycled(excluding valuables) and the amountdisposed.
* Recycling rate is calculated by dividing
the amount recycled (including
valuables) by the amount generated(including valuables).
* Total emissions of BOD and COD are
calculated by multiplying the average
concentration by the amount ofwastewater.
