Pursuing Environmental Management
Komatsu Earth Environment Charter（June 2010 revision）〈Corporate Principles〉

1. Contributions to Realization of Sustainable Society

Mankind must not only promote the further growth of a rich and comfortable society but also pass down this indispensable environment of our planet earth to future generations in a sound and healthy condition.
We, at the Komatsu Group, define environmental conservation efforts as one of the highest priority managementtasks, and endeavor to contribute to the sustainable growth of society by integrating advanced technologies into environmental conservation efforts in all our business activities. This is represented by our hybrid construction equipment
which features a substantial reduction of CO2 emissions while in operation and by our superior manufacturing.

2. Simultaneous Realization of Environmental and Economic Performance

We are committed to improving both environmental performance and economic efficiency, as a group of companies
working toward superior manufacturing for customer satisfaction. To this end, we constantly take up the challenge ofadvancing technologies to develop creative products that improve both environmental performance throughout the
product s life cycle and the product s economic performance at the same time.

3. Observance of Corporate Social Responsibility

Each company of the Komatsu Group promotes environmental conservation by not only complying with the applicable laws and regulations of the concerned host community, region and country but also by establishing its voluntarystandards which consider global and local environmental concerns. Each company of the Group also strives to fulfill
its corporate social responsibility by actively participating in local environmental conservation programs and thereby
promoting close-knit communication with local communities, while striving to become a company trusted by all
Komatsu stakeholders.

〈Guidelines for Corporate Activity〉

1. Basic Stances on Earth Environmental Problems

We, at the Komatsu Group, work for sustainable society and earth environment through our global business
operations by addressing the following four environmental problems with the stances discussed below.
1）Climate Change
We will reduce the use of energy and emissions of greenhouse gas in all phases of our business activities ranging
from research and development, procurement, production and logistics to sales and service as well as in the
total life cycle of our products and services.
2）Establishment of a Sound Material-Cycle Society
Through our business processes, we work to minimize the use of natural resources, such as materials and water,
promote their re-use or recycle them as much as possible, and expand Zero Emissions from our manufacturing
activities around the world. At the same time we ensure the thorough management of waste materials in all ourbusiness domains, including our suppliers and distributors. We also continuously work to increase the recyclability rate of products at the time of disposal.
3）Conservation of Air, Water and Other Environments as well as Management of Chemical Substances
We comply with not only local laws and regulations but also with our established standards concerning theconservation of water quality, prevention of air pollution, noise and vibrations.
As much as possible, we also ensure the thorough management of chemical substances for use in our businessactivities, while continuously reducing the use of potentially harmful chemical substances or replacing them withalternative substances for discontinuation of their use.
4）Biodiversity
We recognize biodiversity as one of the important issues concerning the earth environment, evaluate, understand and analyze impact on it in all our business domains, and work on our tasks according to the criteria of thehighest impact and/or the most effective actions.

2. Framework of Global, Group-wide Environmental Management System

The Komatsu Head Office, as well as the manufacturing facilities and main companies of the Komatsu Group,
already with ISO certifications, will work to maintain and improve their environmental management system, whileother manufacturing facilities and suppliers will also work to establish their environmental management systems andreduce their environmental impact.
The Komatsu Environmental Committee develops environmental action plans and common guidelines for the
Komatsu Group. Based on these Group-wide plans and guidelines, each division or company sets up its own mid- tolong-term targets, develops and implements specific action plans, reviews them regularly and works to continuously
improve them.

3. Environmental Education and Communication

We believe that it is important to enhance the environmental awareness of each and every employee and thereby
actively promote environmental awareness and education programs for all employees.
We will gather environment-related information concerning not only our manufacturing facilities but also otherrelated entities, such as major affiliated companies and suppliers, and strive to disclose such information, thereby
facilitating proactive communication with all our stakeholders, such as customers, employees, local communities
and suppliers and further expanding the content of environmental communication.

Acquiring ISO14001
Komatsu has implemented a Group-wide initiative to acquire ISO14001 certification, an international standard forenvironmental management systems. The objective is toenhance management quality by strengthening systematic
steps towards environmental conservation.
Since 1997, several manufacturing facilities both inside
Japan and abroad received certification. In FY2005, thefour plants belonging to Komatsu Ltd. (the parent company), the Awazu, Osaka, Mooka, and Oyama Plants, acq u i re d i n t e g r a t e d c e r t i f i c a t i o n . A s t h e s e c o n d s t e p , i n
FY2007 Komatsu added its major affiliates in Japan andyet-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.

The thermoelectric power generation module is a device
that utilizes the Seebeck effect, where two different metals
are connected and temperature difference is applied at the
point of contact, which creates an electrical current thatflows between the metals. We are distributing this device
through KELK Ltd. Through the heat-treating furnace afterburner s combustion heat at the Awazu plant, power is continuously generated and fed back into the power system. In

Initiatives to Mitigate Climate Change
in Business Operations
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. However, due to theincreased fuel consumption by engine research and testing, the index for the CO 2 emissions per unit of manufacturing value worsened compared to the previous fiscal year.
Development of a new generation engine will continue thisfiscal year but the CO 2 emissions index will be reduced
through measures such as renewing old buildings of over
40 years with a building that adopts the latest energy-saving technology.

Updating the buildings using the latest energy-saving
technology
While implementing power usage reduction activities
company-wide, we found that if we incorporate energy-saving technology in structures being rebuilt, it would be possible to reduce power consumption by about 50% in places
such as office buildings and assembly plants, where theprimary power consumption is due to lighting and air conditioning. Because over 60% of Komatsu production buildings were built over 40 years ago, there have been cases
where the narrow spacing between posts inhibits the construction of efficient production systems.

CO 2 Reduction of Suppliers
In order to promote the CO 2 emission reduction of suppliers, major outsourcing suppliers were targeted for promoting the spread of Komatsu s energy-saving activities(activities to reduce power consumption by 50% [= production reform]).
In FY2013, more suppliers were introduced to power reduction categories adopted by various business facilities
and case studies; horizontal expansion through the cooperation of Komatsu and suppliers will broaden power reduction activity field and promote activities.
In FY2014 the activities will continue to be promoted byworking to visualize the improvement activities of eachcompany and horizontal expansion.

By deeply integrating ceiling lighting and making LED
lighting modulated, fine-tuned control of lighting is possible. This allows for a reduction in lighting power during theday.

Power Generation with KELK s Thermoelectric Elements
Five years ago the Awazu Plant introduced KELK s thermoelectric element power generation for their carburizing
furnace for the improvement of durability and establishment of a safety system .
This time, KELK s newly developed power generation unit
was introduced and we will continue working jointly with
KELK to confirm durability, develop heat recovery technology, and reduce costs .

Overhead craneLower the CO 2 of Global Transport (Basic Unit of
CO 2 Emissions per Cargo Weight)

In 2011, Komatsu began improving its assessment of
CO 2 emissions from logistics operations for its 10 major international business locations.
Improvements were made on a consolidated basis globally at all 25 business locations, including domestic locations.
Average transport distance increased for domestic andoverseas in FY2013. As a measure to address the reduction of increasing CO 2 , expanding the modal shift will becentral to furthering improvements.
As a result, improvements of -6.3% domestically and-1.8% abroad were achieved but there was a variation in
the average distance of transportation due to a change indestination and the basic unit of CO 2 emissions per cargoweight increased 4.6% domestically and 3.0% abroad.

Reducing CO2 Emissions in Non-manufacturing Divisions
With the revision of the Act on the Rational Use of Energy,
all Komatsu business units are assessing CO 2 emissions inan effort to achieve reductions. The energy consumption of
non-manufacturing divisions, including the Head Officebuilding and the Research Division is shown in the tablebelow.

As the global center, Komatsu established PT Komatsu
Reman Indonesia (KRI), which supplies parts, such as engines and transmissions for large-size construction machinery, and PT Komatsu Indonesia (KI), which supplies
oil-pressure cylinders. Komatsu also established anotherglobal center, Komatsu Reman Center Chile (KRCC), which
provides components for electric dump trucks.
Additionally, Komatsu established PT KOMATSU REMANUFACTURING ASIA (KRA) in Indonesia to recycle components of large-size construction machinery. For countries
that are not part of our global supply chains, such as China, Russia, India and Brazil, we have established individual
Reman Centers.

Effective Utilization of Resources in
Manufacturing Operations (Waste)
In tandem with reducing the amount of waste produced
during manufacturing operations, Komatsu engages inzero emissions activities to use waste materials as res o u rc e s . S t a r t i n g i n F Y 2 0 1 1 , K o m a t s u s e t n e w m e d i um-term goals for our recycling rate and for the amount of
w a s t e g e n e r a t e d p e r u n i t , a n d w e a re w o r k i n g t o w a rd
those goals. In an effort to attain zero emissions, Komatsu
raised the target recycling rate which was 99.5% or greater
by FY2015. Then in FY2013, the recycling rate was 99.5%,
making it the third year in a row to achieve the mid-termgoal early. 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 of waste accordingly.
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 33.3%, compared to the FY2005 level. Komatsu aims to continue its effective separated waste collection
policy to achieve its medium-term goals.

In FY2011, Komatsu set a new medium-term target ofachieving a 25% or greater reduction in the amount of water used per unit of manufacturing by FY2015, comparedto the FY2005 level. The water-conservation campaign
concentrates on manufacturing facilities with extensive
groundwater usage located in the Hokuriku District. The
Company has achieved reductions in the amount of waterused per unit of manufacturing by 52.4% compared to 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 temperatureof cooling water used for heat treatment, and the installation of water-circulation equipment. As a result, the Awazu
Plant was able to reduce water usage by more than 75%
per unit of manufacturing value.
Also, from FY2014, the goal was changed to a mid-termtarget value of an over 50% reduction compared to
FY2005.
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.

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 employee sawareness of the need to preserve local ecosystems.

Initiatives of Each Business Facility■ Oyama Plant: Biotope Satoyama Construction (Komat-

su Manabino Mori)
At the Oyama Plant, 10,000 tons of flood-control basinsand green space (untouched by human hands) were preserved on the plant s premises. We have begun construction to create a biotope and natural wood in this area as
Komatsu Manabino Mori.
Colonies of herons, some ducks, kingfishers and otherbirds, as well as several rare plant species have been observed in this area. Aside from being the focal point of employees biodiversity conservation activities, we are alsoplanning to make it a part of the factory visit course, toraise interest in those coming to observe the factory.

Komatsu Manabino Mori (Satoyama, natural wood area)■ KOMATSU CASTEX: Natural Revival of Water Lilies(Euryale ferox)
Some euryale ferox water lilies, a plant that has been categorized as extinct in the wild (reference material:Red Data
Book Toyama 2002), was transplanted from the Himi City
Junicho Lagoon (the only place in the prefecture with wild
euryale ferox) to theponds at the Himi
plant. By caring forthe surrounding areaand making sure theplants get enoughdredging and sunlight, we were able toproduce the natural
revival of the euryale
Euryale ferox
ferox water lilies.
■ Practical Test Section of Development

Division takes on the Biodiversity No Net Loss* Challenge
The Practical Test Section is challenging themselves toachieve Biodiversity No Net Loss by working to create anenvironment easy for various creatures to inhabit, and bybringing in saplings from around the factory to protect andcare for the trees, with the goal to re-plant it into nature at
the right season.
* The idea to minimize
the effect of business
operations on biodiv e r s i t y, w h i l e d o i n gactivities that contribute to restoring biodiversity, to offset loss
to the whole ecosystem.

Komatsu Group companies periodically report and archive environmental measurement results, in accordancewith applicable laws and regulations of national and local
authorities. In FY2013, there was one instance of a minor
violation of environmental laws and regulations (forgetting
to submit a notification for a specific facility), but since then
the notification has been submitted. However, Komatsu
has had no major accidents that could result in pollution.

Addressing Soil and Groundwater Contamination
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 since2005. 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.

Managing PCB (Polychlorinated Biphenyl) Waste
Komatsu stores and manages PCB-containing waste,such as transformers, in accordance with Japan s Law
Concerning Special Measures Against PCB Waste and the

Waste Disposal and Public Cleansing Law. In FY2008,
Komatsu entrusted PCB disposal to the Japan Environmental Safety Corporation (JESCO). A total of 335 PCB-containing capacitors were disposed of by FY2012. In FY2013,
JESCO disposed of an additional 225 capacitors.
Additionally, with the start of treatment of stabilizers at JESCO, 2868 units of fluorescent lamp and mercury lamp stabilizers were treated ahead of schedule in Hokkaido Office.
Continuing through 2014, we plan to carry out further disposal work to locate low-concentration PCB waste as well.

Management of Chemical Substancesand Pollution Prevention
Reducing the amount of PRTR-related
substances
The number of substances covered by PRTR* with a handling volume exceeding 1 ton (0.5 tons or more for Class I
Specified) is 23, which one substance has been decreased
since last fiscal year. The three substances of xylene, ethylbenzene, and toluene included in paints and thinners account for approximately 94% of the emissions from domest i c g r o u p p r o d u c t i o n s i t e s . A d d i t i o n a l l y, m o s t o f t h eemissions are released into the atmosphere.
At domestic Komatsu group production facilities, initiatives such as switching to paint with lower content of PRTR
substances, using high-solid paints, improving coating efficiency, and reducing film thickness, are being undertaken
for the continuous reduction of transaction volume. Also,
for substances with a high transaction volume, transitions
are being made by secondary materials including chemical
substances with lower impact on humans. In fiscal 2013,
the transaction and emission volume was reduced by approximately 9% compared to the previous year.

the Kanazawa plant, solvent recovery equipment is used torecover and reuse thinner in order to reduce the emissionof solvents.
In fiscal 2014, the paint consumption volume will be reduced through the reduction of film thickness to further reduce VOC emissions.

Reducing the amount of VOC released
The majority of VOC emissions are from VOC containedin paint such as ethylbenzene and xylene. In fiscal 2013,
emissions were reduced by approximately 1.7% from theprevious fiscal year, but the basic unit slightly increased. At▶ Workflow

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, andis also being implemented in other overseas subsidiaries.
