Environmental Report Digest 2017Management that Prioritizes ESG
Since the 1990s, Komatsu has steadily worked on Environment ,Social and Governance , responded to social issues throughour primary business, and conducted business activities with thegoal to increase the trust of our stakeholders. In April 2016, weconnected these past endeavors with the Mid-term Management
Plan Together We Innovate GEMBA Worldwide to strive evenmore proactively for ESG. Furthermore, along these same lines,
we have chosen 5 goals closely related to Komatsu s businesssuch as Climate Action , Industry Innovation and Sustainable
Cities from the Sustainable Development Goals (SDGs) put
out by the United Nations.
The Mid-term Management Plan s aim regarding the global
environment is to increase the trust in Komatsu by working on
issues such as innovation in the GEMBA (work site) where construction equipment is used and production occurs, reduction of
CO2 and effective usage of resources.

Endeavors for the Environment
through Innovations in the GEMBA
With construction equipment̶the primary product ofKomatsu̶approximately 90% of CO2 emissions over the life cycle
is generated during the operation of the machines. In February
2015, Komatsu started the utilization of Smart Construction in
Japan. This is Komatsu s Dantotsu Solution which provides
our customers with the GEMBA of the future with increased
safety and productivity by using ICT technology to automate theequipment operation of construction machines as well as connect all data involved in a construction site, such as geography
data measured by drones, design data and work progress. Thisis exactly an example of innovation at work in the construction

site, and makes possible an energy efficient work site̶in otherwords, a low CO2 emissions GEMBA. Komatsu will further propel
this type of Smart Construction to expand the future GEMBA
with excellent environmental performance.
Furthermore, we will promote the streamlining of production at
the production sites through IoT. In 2015, Komatsu achieved thegoal of electricity used in our domestic plants being reduced byhalf compared to 2010, and while doing so moved forward withmaking visible the production process by using IoT. Afterwards,
this was further advanced to develop KOM-MICS (Komatsu
Manufacturing Innovation Cloud System), the system as a consolidated management of production data, such as the operating
conditions of the production equipment. Currently we are trying
to make this innovation a reality at the production sites at ouroverseas plants and partner companies. By doing so, production
efficiency will be increased and wasteful consumption of materials and resources will be reduced, making it possible to have a
production process with a low environmental impact.
In April 2017, Komatsu added KMC: Komatsu Mining Corp.
(previously Joy Global Inc.) to our group. Going forward, we will
share Komatsu s founding philosophy with KMC, promote theinnovation in the GEMBA together, and work on solutions forenvironmental issues.

Komatsu's Connected Plants―Increasing Productivity andConserving Energy with IoT―

Step2

Special Story
Komatsu has been promoting IoT (Internet of Things) for the operation sitesof construction machinery using systems such as KOMTRAX and KomConnect.
Also, at the production site of the plants, aiming for increased productivity andenergy conservation through IoT, we move forward with reforms and improvements of production process, by“making visible”the condition of manufacturing
facilities and the state of production, as well as using the KOM-MICS (Komatsu
Manufacturing Innovation Cloud System) which unifies information.
In 2011, Komatsu commenced with activities to reduce electricity usage byhalf, and in 2015 achieved the 50% reduction in both electricity usage at peak
hours and overall electricity usage. The significant results brought about by“making visible”the manufacturing process using IoT, as well as the consequent improvements, have been developed into KOM-MICS.
The implementation of KOM-MICS is made up of four steps and currently weare at the Step 2 stage.

Example of Decrease in Operational Time for
Machine Processing
Non-processing Time

Unlike automobiles, construction machinery is a high-mix
medium volume production, and the manufacturing facilities that
handle them also vary widely, therefore we had not made muchprogress in getting a comprehensive overview of individual operational statuses and electricity usages.
For this reason, we first“made visible”the operational status ofeach manufacturing machinery (equipment processing machines,
welding robots) by using IoT technology for monitoring. For
example, in“machining”where material is cut and processed, we
saw that there was a lot of electricity consumption by ancillaryequipment during times when processing was not actually happening, such as when cutting was not going on during setup andwhen cutting conditions were not right and taking extra time. For
this reason, we took measures to shorten the setup time andcorrect the cutting conditions by doing studies using simulation,
thereby decreasing the work time by 50% in one case. In thisway, by taking measures such as shortening the processing time
and turning the power off when not processing or setting it onenergy conservation mode, we were able to greatly reduce theamount of electricity used by facilities including wait times.

As the next stage after“making visible”
the individual manufacturing facilities, weconnected the manufacturing facilities using
IoT technology and developed KOM-MICS:
the system that unifies the information
about things like the condition of the production facilities and their processing status.
Not limited to domestic plants, the processing facilities and welding robots of overseas
plants and partner companies have beenconnected, and the data for operation rate
and production efficiency can be seen inreal time. Because of this connectedness,
we can see which facilities still need
improvement and we can quickly share theimprovements of individual processing facilities to similar facilities. Since the whole
picture can be seen by this connectedness,in installing energy saving devices, we havebeen able to install them with accurateprioritization.

Promoting Environmental Activities at
Group Sales and Rental Agencies

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 majoraffiliates in Japan and yet-to-be-certified non-manufacturing facilities – notably the Head Office – to the above four plants, withintegrated 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 recertification
qualification again in March 2015, and will continue to work on
improving the quality of management in Japan.

Komatsu ManCorp. ,ufacturing Rus. LLC , andHensley Lingfeng Co., Ltd(China) acquired certification,and in FY2014 Cabtec(Thailand) acquired certification as well.
In FY2015, Yida Nippei
Tool Corporation (YNC) alsoacquired certification andwe were able to achieve thegoal of having 100% of ouroverseas production facilities certified.
Hereafter, we are planningto expand acquisition of certification to the sales andservice divisions as well.

Komatsu promotes education and guidance for making
improvements, with safety and environment as a central theme,
for the sales and service departments.

Revising the Environmental Guidelines for Sales
Agencies
In January 2017, the Revised Environmental Guidelines for
Sales Agencies was distributed to sales agencies and rental
companies of construction machinery, as well as to fork lift sales
agencies and group rental companies. The guideline contains
compliance items and standards regarding environmental issues(waste treatment, waste-oil treatment, treatment of wastewaterfrom vehicle washing, etc.) that are closely related to each company s work sites.

Promoting the Educational Activities of Group
Sales and Rental Agencies
ISO14001 Integrated Certification

The implementation method of the Environmental Guidelines
for Sales Agencies uses the PDCA method, whereby the
improvement of environmental aspects is effected by repeating

its cycle. Komatsu works
jointly with their counterparts at various companies by visiting the sitesof various sales agencies
and rental companies toensure compliance with
theEnvironmental
Guidelines for Sales
Agencies as well as
Environmental education at a groupinspecting sites, realisales agency
ties, and actual products to implement support activities such as supervising the sites
and proposing remedial actions that are tailored to each location(implemented at 70 locations in 20 companies in FY2016).
Also, as a systematic effort towards environmental conservation at the group sales and rental agencies of construction
machinery, action is being taken to qualify for the international
standard on the environmental management system (ISO14001),
with the goal to achieve qualification during FY2017.

Supporting Supplier s Environmental
Management System

Promotion of Komatsu Midori-kai s Environmental
Management System Certification
In order to strengthen the environmental management of
suppliers, Komatsu Midori-kai companies that account for 74%
of funds raised are requested to obtain certification for their environmental management system.
In FY2016, 162 companies (all companies requested to obtainenvironmental management system certification) had been certified for ISO14001 , ECOSTAGE , etc., promoting environmental management activities.

TO P I C S
SBT (Science-Based Targets) Approved
Komatsu s CO2 reduction objectives have been approved to be SBT as of April
11, 2017.
SBT (Science-Based Targets) is "setting goals that are compatible with
science."
Although CO2 reduction objectives were submitted by various countries at the
COP21 (Paris Agreement), even with the summation of target values, the average global temperature in 2100 cannot be held down to an increase of less than
2℃ compared to temperatures before the Industrial Revolution. Therefore, after
a detailed examination by the businesses of the world, reduction objectives havebeen reassessed and SBTi (SBT initiative: CDP, Global Compact, WRI, WWF) is
supporting and approving SBTs to reach the goal of an increase of less than 2℃.
Komatsu s SBT meets the requisites of the temperature increase of less than 2℃
scenario.
Komatsu s SBT(1) SCOPE1+2: Base unit -49% (Target Year 2030; Base Year 2010)(2) SCOPE3: Total -46% (Target Year 2030; Base Year 2012)*Furthermore, although Komatsu disclosed new mid- and long-term objectives(2020, 2030) in 2015, since the
SBTi s requisites (such as using thesame base year for both domestic
and overseas) has different conditions than the new mid- and long-term
objectives, the target values differ, but
the reduction rates are the same.

Low Carbon Type Construction Equipment Certified Models:
HB205-2, HB215-2, HB335-3, HB365-3 and others, a total of
12 models (As of April 2017)
Also, the bulldozer D155AX-8, the hydraulic excavator PC30011, the wheel loader WA470-8 and others-a total of 11
models-have been certified as the Ministry of Land, Infrastructure,
Transport and Tourism s Construction Machines Fulfilling Fuel
Economy Standards to be construction equipment with great
fuel economy performance. (As of April 3, 2017)

The main bulk of the CO2 emissions amount produced over the
lifecycle of construction equipment is during product operation,
which accounts for approximately 90% of the total. With this inmind, in order to reduce CO2 emissions from their products,
Komatsu has worked on the 3 approaches of Dantotsu Products,
Dantotsu Service and Dantotsu Solutions.
Step1: Reduction of CO2 Emissions through Dantotsu Products
Step2:Reduction of CO2 Emission by Products through Dantotsu
Service (KOMTRAX)
Step3:Reduction of CO2 Emissions for Overall Construction
Work through Dantotsu Solutions (SMART CONSTRUCTION using ICT Construction Equipment)

Step1: Reduction of CO2 Emissions through Dantotsu
Products
We will provide products with great fuel economy performanceand reduce CO2 emissions.
For example, the hybrid hydraulic excavator, which Komatsu
was the first in the world to introduce to the market, is one suchproduct.
These hybrid construction machines have been certified by the
Ministry of Land, Infrastructure, Transport and Tourism of Japan
as Low Carbon Type Construction Equipment.

In 2013, Komatsu introduced the ICT bulldozer D61PXi-23
with the world s first automatic blade control capabilities to theNorth American, European and Japanese markets. Further, in
2014, Komatsu introduced to the market a hydraulic excavatorwith a semiautomatic control function, model PC210LCi-10 for
North America and Europe, and model PC200i-10 for Japan.
Preliminary calculations based on in-house test construction
data for ICT hydraulic excavators showed that foreslope shaping
work using the PC200i-10 resulted in an approximately 30%
reduction in fuel use. Also, preliminary calculations based on
in-house test construction data for ICT bulldozers showed thatland preparation work using the D61DXi-23 resulted in an
approximately 25% reduction in fuel use, and we were able tosee that like the ICT hydraulic excavator, CO2 emissions werereduced.
Komatsu is implementing SMART Construction which uses
these types of ICT construction machines and taking current
topography measurements using drone and 3D scanners inorder to promote and make visible the efficiency and work process of construction sites.

Reduction of CO2 Emissions from Construction
Equipment (Estimate of Amount of Reduction
Contributions)
In Komatsu s Mid-term Management Plan (FY2016 - FY2018),
we set the goal of achieving 25% reduction by 2025 in CO2 emissions per amount of work from construction equipment ascompared to 2007. To assess progress, the construction equipment manufactured each year is being compared to theequipment capabilities of the standard year (FY2007) and estimating the CO2 reduction contribution amount resulting from theimprovement in fuel economy and work efficiency.
As a result, the machines manufactured in FY2016, comparedto the standard year (FY2007), achieved a 7.4% reduction in CO2emissions, and if these machines were operated for one year, wefound that it would contribute to reducing the amount of CO2 byapproximately 150,000 tons.

Reducing CO2 Emissions in
Manufacturing Operations

（kt）
400

As a part of our efforts to mitigate climate change, Komatsu set
mid and long term objectives in Japan and overseas operations
for the amount of electricity, fuel gas, fuel oil, and other types ofenergy used in manufacturing operations, using CO2 emissions
per unit of manufacturing value as the indicator, to proactively
reduce the amount of CO2 emissions units.
In 2010, in response to the climate change issues raised in the
Post-Kyoto Protocol, we set a mid-term objective that by 2015
we would reduce CO2 emission levels by 40% compared to thelevels in 1990. Since then however, using the cutting electricity
use in half activities that followed the Great East Japan
Earthquake as an impetus, we set an ambitious goal of a 54%
reduction compared to FY2000 levels and pursued activities toreduce power consumption and achieved great outcomes. As aresult, in February 2017, we received the Kanto Bureau of
Economy, Trade and Industry Director s Award as an energy
management superior business operator. From FY2016, wehave set new mid- and long-term objectives for both domestic
and overseas operations, and are moving forward with further
improvement activities.
In FY2016, as a result of energy-saving activities undertaken
based on the lateral spread of various production reforms, theCO2 emissions per unit of manufacturing value was reduced by
41.0% compared to FY2000 levels. However, due to an increasein electricity use for the summer/winter air conditioning and thefuel to test components, the index was worse than the previous
year. The ratio of renewable energy for in-house power generation was 19.2%, due to the cutback in in-house power generation
using fossil fuels, an increase of 1.4 times the previous year.
CO2 emission at Komatsu s overseas manufacturing sites
have also been reduced by 28.7% compared to FY2010 as aresult of fuel conversion and lateral spread of improvement
examples from Japanese plants.
For FY2017, aiming for the achievement of mid-term objectives, we will work towards further reduction in CO2 emissions
index numbers by updating buildings that are over 40 years old
to building that incorporate the newest energy-conserving technology, and by making small but steady improvements on job
sites.

In 2011, Komatsu began improving its assessment of CO2
emissions from logistics operations for its 10 major international
business locations. Combined with the improvements that werestarted in domestic locations from 2006, we have now implemented improvements in logistics operations on a globallyconsolidated basis at all 25 business locations.
"Domestically, we are continuing improvements with emphasis
on decreasing transportation distance through efficient use of the
Kanazawa and Hitachi Naka Ports which are located adjacent tomanufacturing plants, as well as the improvement of long distance transport by expanding the use of coastal shipping andrailways (modal shift).
As a results, in FY2016 we achieved an improvement of 4.7%
in CO2 emissions per cargo weight."
Results for overseas operations showed a deterioration of+6.5% compared to the previous year because of the recovery inload amount and the increase in transport distance due tochange in delivery point in the Asia district (especially in China
which has a poor basic unit).

Reman, an abbreviation for remanufacturing, offers the following advantages to customers:● Quality and performance that is the same as new components● Lower cost for "remanned" components● Reduced idle time for construction equipment because of
adequate inventory of "remanned" components● Resource conservation and waste reduction through reuse
and recycling of components

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 andrecycling 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 anddurability information. This important information is reported to
the Group, to help develop components with optimal service life.

As global centers, in Indonesia we established PT Komatsu
Indonesia (KI) which supplies parts such as engines and transmissions for large-size construction machinery and hydrauliccylinders, and in Chile we established PT Komatsu RemanCenter Chile (KRCC) which supplies components for electric
dump trucks.
Additionally,
KomatsuestablishedPT
KOMATSUREMANUFACTURING ASIA (KRA) in Indonesia to recycle allcomponents of large-size construction machinery exclusively for
the Indonesian market.
For countries that are not part of our global supply chains(China, Russia, India and Brazil), we have established individual
Reman Centers, and in December 2016, we established a new
Reman center in Magadan of Far East Russia.

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

Effective Utilization of Resourcesin Manufacturing Operations (Waste)

Effective Utilization of Resourcesin Manufacturing Operations (Water Resources)

In tandem with reducing the amount of waste produced during
manufacturing operations, Komatsu is working on "zero emissions" activities.
Starting in FY2016, we set new mid-term objectives (refer tochart below) for both domestic and overseas manufacturing
facilities and started maintenance and improvement activities forthe reduction of waste generated per unit in the manufacturing
operation and the recycling rate.
By pushing for reduction in the amount of waste, strict adherence to separating waste materials, and increase in conversionof waste materials to resources, the waste generated per unit for
manufacturing operations in Japan was reduced by 14.1% compared to FY2010, meeting the goals ahead of schedule. However,
due to temporary increase in waste as a result of the waste solution reduction mechanism breaking down and the discarding of
unnecessary items, the waste generated per unit was worse thanlast year. The recycling rate was 99.6%, which means we wereable to maintain a rate of over 99.5%.
Due to factors such as the strict adherence to separating
waste materials, the waste generated per unit for the overseas
manufacturing facilities also decreased by 15.1% compared to
FY2010, meeting the mid-term objectives ahead of schedule.
However due to the discarding of unnecessary items and anincrease in the amount of foundry sand used for quality maintenance, the waste generated per unit was worse than last year.
The recycling rate was 92.1%, an improvement of 0.7 points
from last year.
Going forward, while considering a re-evaluation of mid-term
objectives for both domestic and overseas manufacturing facilities, we will work even harder to strictly adhere to separate wastematerials and further activities for improvement.

Starting in FY2016, we set new mid-term objectives (refer tochart below) for both domestic and overseas manufacturing
facilities and started activities to reduce the amount of waterused.
For the manufacturing facilities in Japan, through the reuse ofwater during the processing and the elimination of wasteful dayto-day practices―mainly in the facilities located in the Hokuriku
District which are major users of underground water―water used
per unit of manufacturing was reduced by 49.6% compared to
FY2010, achieving mid-term objectives ahead of schedule.
In particular, Komatsu Castex Ltd. greatly reduced its water
consumption compared to the year before through measures
such as circulating the cooling water of the transformer for thearc furnace.
Also, at overseas manufacturing facilities, measures such as
purifying the water discharge from the manufacturing process forrecycling and reducing wastefulness resulted in water used perunit of manufacturing decreasing by 31.9% compared to
FY2010, achieving mid-term objectives ahead of schedule.
Going forward, while considering a re-evaluation of mid-term
objectives for both domestic and overseas manufacturing facilities, Komatsu will work even harder to promote activities that
reduce the amount of water used.

Ex-situ conservation of rare specifies underway in an
in-plant biotope-observing plant with guidance fromlocal experts
With the cooperation of local experts, taking action to conserve
rare species outside of their habitat range in biotope lake locatedon the plant premises Komatsu Castex Ltd. (located in Himi City,
Toyama: hereinafter KCX), the only company in Japan producing
parts for construction equipment and mining equipment by casting, has gained the support and guidance of the curators andbiotope managers of the Toyama University Faculty of Scienceand Himi City's cooperative research center "Himirabo Aquarium"
to create a biotope using the lake located in the "Furusato noMori" (Hometown Woods) within the plant site of KCX main
office. Since 2014, KCX has been working on conserving the rare
species of "Minami Akahiritabira" (Acheilognathus tabira jordani)
outside of their habitat range.
Minami Akahiretabira is a species of fresh water fish indigenous to Japan classified as cypririod acheilognathina
acheilognathus and lives also in Shimane prefecture and Tottori
prefecture of the Sanin Area as well as in Fukui prefecture andIshikawa prefecture. Toyama prefecture is at the north limit of its
habitat in Japan. In 2015 it was classified as an endangered species by the Toyama Prefecture Endangered Species Protection
Measure as being threatened with extinction.
The Minami Akahiretabira is approximately 6cm long, andduring spawning season (April - July), the male shows a distinct
nuptial coloration while the female has the characteristic of growing a oviposting tube to bear eggs inside freshwater clams. Since
freshwater clam is indispensable in outside habitat range' conservation, when a total of 100 Minami Akahirekatabira werereleased in December 2014 and April 2015, about the same
number of freshwater clams (mussels) were released into thesame lake. Furthermore, since mussels become parasitic on thefins of freshwater fish when breeding, Tamoroko (Gnathopogonelongates) and Motsugo (Pseudorasbora parva) were also
released for the breeding purpose of the mussels.
In addition, since the runoff water from the biotope ends up
flowing into the Busshouji River water system that is21

Komatsu Group companies periodically report and archive
environmental measurement results, in accordance with applicable laws and regulations of national and local authorities.
In FY2016, there were no infractions of legal regulations regarding the environment.
No major accidents or legal violations occurred that would
threaten environmental contamination.

Addressing Soil and Groundwater Contaminationn
Komatsu has established guidelines for testing soil and groundwater at our Japan facilities, and we perform investigations
according to applicable laws and regulations at business units
that are to be sold, closed, or demolished. If contamination isfound, the Company takes appropriate measures under thesupervision of local authorities.
We are performing voluntary investigations at currently operating business units in order to check for contamination fromvolatile organic compounds (VOC) from cleaning solvents thatwere used in the past and working on clean up measures.
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 detectedhave 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, and at the same time
we are also checking on the effectiveness of the clean up measures being taken.
Going forward, along with driving the clean up activities, we will
monitor groundwater at the site boundaries to make sure that
off-site outflow of groundwater does not exceed the standards.

Since FY2008, Komatsu entrusted PCB disposal to the Japan
Environmental Safety Corporation (JESCO) and about 90% of
the PCB-containing transformers and stabilizers have been disposed by FY2016.
Continuing through FY2017, we plan to carry out further disposal work to locate low-concentration PCB waste as well.

Managing PCB (Polychlorinated Biphenyl) Waste

Komatsu Ltd.

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 twolevels.
First, the Company continues to promote ongoing efforts to
reduce the environmental impact of Komatsu's business activities. Komatsu also considers biodiversity when deciding how
land is to be used, such as when building factories.
Second, Komatsu is becoming directly involved in the preservation of biodiversity, and at the same time expanding our "one-site,
one-theme activities" to raise employee's awareness of the needto preserve local ecosystems.

downstream, only species that were captured from the Busshouji
River water system were released in order not to affect the original ecosystem.
In August 2016, a year and a half since the release, a survey
was done to see how much the population of the Minami
Akahiretabira had increased. Results from the first and second
surveys made it clear that there was an increase of over 1,000
fish (approximately 10 times the number released). Also, thesurvey results showed that the ratio of fish captured at the timeof the census was over 80% Minami Akahiretabira, which meansthat Minami Akahiretabira is the dominant species within the lakeof "Furusato no Mori".
We hope to continue working on this conservation project withthe guidance of the local curators and biotope managers.

Management of Chemical Substances and
Pollution Prevention

Reducing the amount of PRTR-related
substances
In FY2016 the number of substances specified by PRTR* witha handling volume of 1 ton or more (0.5 tons or more for Class I
specified) was 23 with a decrease of 2 substances from the previous year.
Among all PRTR-listed substances. the three substances ofxylene, ethyl benzene and toluene account for approximately
92% of the emissions from Komatsu and Komatsu Group manufacturing facilities. Most of these emissions are released into theatmosphere.
At the Komatsu and Komatsu Group manufacturing facilities,
we are undertaking initiatives such as switching to paints withlower proportion of PRTR-listed substances, using high-solid
paints, improving coating efficiency and reducing film thickness.
Also, we are changing the substances handled in large volumes
are to secondary materials that contain less PRTR-listed substances in order to reduce the handling volumes of such
substances. The amount of emissions for FY2016 has been
reduced by about 3% from the previous year.

Breakdown of the Amount of PRTRrelated Substances Released andTransferred from Komatsu Group
Manufacturing Facilities in Japan

Komatsu has been making efforts from an early stage to reduce
the use of asbestos, lead, and other substances of environmental concern. In FY1999, Komatsu created its own list of banned
substances and substances approved for use only in limited circumstances (Refer to ""Substances of 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 Manufactureof Chemical Substances Control, as well as regulations in othercountries.
In addition, Komatsu has begun comprehensive control ofsubstances of environmental concern. Recently, in compliancewith REACH *1, Komatsu began revising its listing of substances
designated as approved for limited use, or banned to use.
Through the cooperation of suppliers, the Company has initiateda system to strengthen control of substances of environmental
concern in its products. This system has been deployed in Japanand Europe, and is also being implemented in other overseas
subsidiaries.
By using this system, we identify SVHC (substances of very
high concern) in vehicles currently in production and in newlyIndex per Unit of Manufacturing Value(Compared to FY2005)

Water Related Risk Management
Based on the Earth Environment Charter, up to the first half of
FY2015 Komatsu Group has worked on:(1) Promoting the reduction in usage amount (input) and therecycling (circulation) of water.
(2) Activities centered on water quality conservation.
However, in response to the frequency of weather abnormalities and societal demand (2015/1 Water Crisis named as number
one risk at Davos Forum, etc.), from the second half of 2015
"Water Related Risk Evaluation Committee" was newly established, and after six months of study, conducted a "Water Related
Risk Survey" with the main domestic and international affiliates
as subjects.

Results from the Water Related Risk Survey (conducted at 45 global affiliates/divisions in January
2016)
Water related risk as Komatsu Group(1) Effect of heavy rain on operations/business(2) Risk of pollution from drainage(3) Effect of river flood on the supply chain
Based on the above results, as Komatsu Group's policies
related to water, from FY2016̶along with continuing our previous activities̶we are newly promoting "Water Related Risk
Reduction Activities" in order to minimize as much as possible
the effects of water related problems on the business of KomatsuGroup.

Domestic Example Case (Oyama and Tochigi
Plants)As a measure against heavy rain, on the plant premises we arebuilding three reservoirs that can hold up to an hour's worth of
100mm/h rainfall, as well as installing heavy rainfall water pipes,
building underground reservoirs, and widening the rainwaterdrainage ways. Also, in order to prevent water flowing outside of
the premises, we are installing water block walls and water stopbars.
* The reservoir is also serving to alleviate the surrounding district's lack of drainage capacity.

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 theamount recycled (including valuables) by theamount generated (including valuables).
*Total emissions of BOD and COD are calculated by multiplying the average
concentration by the amount of wastewater.

Energy consumption*The heat energy conversion factor is calculated in keeping with Greenhouse Gas
Emissions Calculation - Reporting Manual,
which is based on the act on Promotion of
Global Warming Countermeasures.
