Annual sales in Honda’s six regions by unit volume (FY2009)
Global Operations and Marketplace
Advancing operations in six regions
Driven by its philosophy of building products close to the customer,
Honda manufactures its products in six different regions worldwide. In
FY2009 we delivered 23 million units to customers around the world.
Always conscious of the environmental impact of its operations, Honda
is working hard to take environmental responsibility to ever higher lev-
els around the world.
In 2006 Honda became the world’s first automaker to announce
global CO
2
reduction goals for its products and production activities. It
also implemented a proactive strategy to help stabilize climate change,
taking efforts to even higher levels. As a global manufacturer, Hon-
da strives to develop products with the lowest in-use CO
2
emissions
manufactured at plants with the lowest per-unit CO
2
emissions. Honda
Group companies worldwide continue to advance a wide range of ini-
tiatives for the reduction of environmental impact.
Honda discloses its environmental policies and practices in the CSR Report, in the Honda Environmental Annual Report
and on its website ( The CSR Report outlines Honda’s environmental initiatives in
an easy-to-understand way. The Environmental Annual Report presents in greater detail Honda’s fundamental policies and
future direction with respect to the environment, as well as the results of the year’s environmental initiatives. In addition to
covering both general and specific environmental information, the website presents the history of Honda’s environmental

initiatives.
Starting this year, Honda is presenting the report in two parts: “Honda Environmental Annual Report 2009” and “Hon-
da Environmental Annual Report 2009: Case Studies and Supplementary Information” are both available on the website,
and “Honda Environmental Annual Report 2009” is also available in printed form.
As restructured, the printed Report will play an even stronger role in our Plan, Do, Check and Act (PDCA) process for
environmental initiatives. The Case Studies and Supplementary Information document supplements the information con-
tained in the printed Report, introduces additional initiatives in each domain and presents Substances of Concern output
data for each Honda facility and product area. Honda produces the Honda Environmental Annual Report based on internal
guidelines.
By disclosing a wide range of information, we hope to facilitate communication and feedback, thereby strengthening
our environmental conservation initiatives going forward.

Honda is striving to reduce the noise caused by acceleration. The main sources of acceleration noise are the engine,
the intake and exhaust systems, and the tires. The technologies listed below were implemented in the Insight released
in February 2009 in Japan to suppress engine and intake and exhaust noise, reducing exterior noise to 72 dBA, lower
than the 76 dBA required by regulations.

Honda Environmental Annual Report 2009: Case Studies and Supplementary Information
Since October 2007, all Honda automobiles sold in Japan have met the guidelines for in-vehicle VOC content man-
dated by Japan’s Ministry of Health, Labor and Welfare. Honda is the first automaker to achieve these standards for all
automobiles, including commercial vehicles.
Reduction of in-vehicle VOCs
The completely redesigned, fourth-
generation Honda Odyssey was released in
October 2008. It is available with a 2.4-liter
i-VTEC engine that combines reduced
precious metals content with enhanced
emissions performance. The latest model
features a newly developed integrated
cylinder head exhaust manifold and an
extremely heat-resistant catalytic converter
located directly beneath the manifold.
Together, these technologies maintain a

highly efficient system for purifying exhaust
emissions with reduced use of rare precious metals. The Odyssey features a linear air-fuel ratio sensor,
an oxygen sensor and an air-flow sensor for high-precision air-fuel ratio control, while a high-atomizing
fuel injector helps reduce exhaust emissions. These technologies give the Odyssey enhanced emissions
performance, allowing certain types to be certified as very low-emission vehicles by Japan’s MLIT.
Introduced in 1994, the Odyssey reached cumulative sales of one million units in Japan in February 2009.
Exhaust emissions
Resin intake manifold in Insight
Honda sought to maximize fuel efficiency and environ-
mental performance in every detail of the 1.3-liter gasoline
engine that serves as the Insight’s main source of power. Be-
tween the cylinder heads and the intake manifold, Honda
placed an EGR plate with highly efficient exhaust pathways.
The implementation of this technology allowed for the use
of a lightweight composite-resin intake manifold, helping to
reduce overall vehicle weight.

A cogeneration (heat and electricity) system generates electricity with a gas
engine and uses the exhaust heat to supply hot water. Overcoming the challenge of
creating a system compact enough for household use, in March 2003, Honda be-
gan sales of a cogeneration unit that combined the GE160V—the world’s smallest
natural gas engine—with an electrical generation system featuring Honda’s original
sine wave inverter technology. In Japan, a cogeneration system that incorporates
Honda’s compact household cogeneration unit has been sold through utility gas
companies under the brand name ECOWILL. In October 2006, Honda introduced
a new unit featuring power generation efficiency of 22.5% and total energy ef-
ficiency of 85.5%. In FY2009, in Japan Honda sold 20,021 units of the ECOWILL
cogeneration system. Cumulatively, Honda has sold 86,285 units since its release.
Sales results for compact household cogeneration systems
Power Products
In December 2008, Honda launched the Yukios SB800, a compact and
lightweight snow thrower that clears snow with a blade in an easy-to-use fashion.
In addition to exceptional fuel economy, the Yukios SB800 features low noise.
When the user releases the throttle lever, engine rpms automatically decrease for
enhanced fuel economy and reduced noise during idling. The use of a resin engine
cover further reduces noise to facilitate early morning snow removal.
In February 2009, Honda introduced the Pianta FV200 gas-powered mini-tiller,
which runs on home-use butane gas canisters. As with the Yukios SB800, when
the user releases the throttle lever, engine rpms automatically decrease to reduce
noise. In addition, noise is reduced through the use of a large silencer, provided as
standard equipment, along with a plastic engine cover.
Noise reduction
Advances in solar cell production and sales
In October 2007 Honda Soltec began commercial production of non-silicon
CIGS (copper, indium, gallium and selenium) thin-film solar cells developed by
Honda Engineering. The width of the energy-generating layers of CIGS solar cells
is approximately 2.4 micrometers, roughly 1/80th the width of polycrystal silicon

cells. Produced with fewer processes and less energy than polycrystal silicon cells,
CIGS solar cells have an approximately 1/3 shorter energy payback time (the time
it takes to recover the energy used in cell production) of 0.9 years.
One challenge faced in the development of CIGS solar cells concerns the ho-
mogeneity of the energy-generating layer. Whereas polycrystal silicon has a maxi-
mum cell size of 15 cm, Honda can produce CIGS substrates that measure as much
as 73×92 cm. To accomplish this, Honda implemented such original technologies
as in-plane temperature distribution with high-temperature processing exceeding
500°C and doping technology based on automotive coating technology. Honda
thin-film solar cells have a highly efficient 11.15% energy-conversion rate. Honda
Soltec has begun selling the cells throughout Japan.

Purchasing
Since most molds are made of metal, they are recycled. However, since some molds are used for many different
service replacement parts, it can be difficult to determine when they can be recycled. In FY2003 Honda began sharing
guidelines with suppliers on mold recycling, leading to standardization of procedures and more proactive recycling.
Recycling of used molds
• 10,119 molds recycled
• 1,410 tons of molds recycled
• 9,760 molds recycled
• 1,360 tons of molds recycled

Transportation
Reducing packaging in the transportation of component parts sets
Completed motorcycles importation and power products transportation

By using returnable cases when importing scooters from China, Honda is continuing to maintain zero landfill dis-
posal of shipping materials. By eliminating the use of cardboard and introducing returnable steel containers, Honda
continues to reduce packaging use. In addition, through the use of returnable steel cases for transporting medium and
large marine outboards in Japan, Honda is continuing to reduce steel and cardboard use.

Honda Environmental Annual Report 2009 : Case Studies and Supplementary Information
In FY2009 the company used 18,069 tons of packaging materials,
a reduction of 3,116 tons, or approximately 15%, from FY2008. As in
FY2008, the use of returnable containers in coordination with charter
flights contributed to the reduction. Honda uses cardboard boxes in
the receiving, shipping and storage of small parts but is increasingly
using returnable containers to store them. Gradually seeing results from
this initiative, the company plans to expand it going forward. In the
area of large parts, Honda has focused on replacement bumpers, for
which there is high demand, creating a simple, environmentally respon-
sible package. As a result, Honda has eliminated cardboard replace-
ment bumper packaging and reduced the total amount of packaging
that bumpers require.

Reducing the use of SOCs
Automobiles
Honda is working to reduce the use of
four heavy metals considered to have adverse
effects on the environment (lead, mercury,
hexavalent chromium and cadmium). In the

production of the Insight and other vehicles
released in FY2009, Honda attained the
reduction targets set by the Japan Automobile
Manufacturers Association (JAMA; see
adjacent chart). The company expanded, by
approximately 10%, the installation of air
conditioners that reduce the use of HFC134a
(baseline: FY1996), using them in 22 out of
24 models. Honda is examining the viability
of implementing air conditioners that use no
HFC134a, and is monitoring new technological developments. By discontinuing the use of PVCs in interior and exterior
resin parts, Honda reduced the content of chlorine in automobile shredder residue to 1% or less in all new models
released in FY2009.
Motorcycles
One of Honda’s commitments is to reduce the use of four heavy metals (lead, mercury, hexavalent chromium and
cadmium) in all models produced in Japan by the end of 2005. The company attained its voluntary reduction targets
by the end of FY2007 and in FY2009 continued to operate within target levels. Honda also eliminated in Japan the use
of polycyclic aromatic hydrocarbons, prohibited under 2010 European regulations.
Power Products
Honda also committed itself to reducing the use of four heavy metals (lead, mercury, hexavalent chromium and
cadmium) in all power products produced in Japan by the end of 2006. No regulatory standards for power products are
in effect in Japan, but Honda is working to voluntarily reduce the use of SOCs in power products in accordance with
JAMA’s voluntary targets. Honda has already attained the targets for lead, mercury and cadmium. Honda has eliminated
the use of hexavalent chromium for all purposes except for anti-corrosion treatments in certain marine outboards.

Recycling oil lters
Honda collects and disassembles end-of-life oil filters to recycle
them as metal and fuel. Honda also reuses some of their components
as production parts. The company has started recovering these filters
through Honda dealers nationwide in January 2004 and began recover-
ing filters from service and repair companies in FY2006. Honda’s goal
is to recover 30% of the oil filters produced in the previous fiscal year.
Recovery and recycling of bumpers
Honda has established a system to collect used bumpers from deal-
ers and recycle them as raw material. In FY2009 the company recov-
ered 239,00 used bumpers from Honda automobile dealers and service
and repair companies, recovering a total of 814 tons of resin. Of this

amount, 236,000 bumpers (803 tons of resin) were to be replaced, and
3,000 bumpers (11 tons of resin) were collected from end-of-life ve-
hicles. Honda used a total of 1,204 tons of recycled bumper resin in
such parts as replacement bumpers, splash shields and splash guards for
automobiles and undercovers for motorcycles.

The Honda Beach Clean-up Project
As one of our community initiatives, Honda developed the Beach Cleaner,
which is used to clean up the seashore. A group of current and retired associates
assembled a volunteer caravan to work with municipal authorities to put this inno-

vative device to work. The towable Beach Cleaner has a simple structure based on
the functions of a rake and a sieve. As it churns up the sand, buried litter is collected
for proper disposal.
In FY2009 the Beach Cleaner Caravan visited 32 sites in Japan and with the help
of more than 1,600 current and retired associates some 6,000 bags of litter were
collected. Starting in FY2010, the associates working for dealers in local communi-
ties will also participate, further expanding the scope of the initiative.
Hello Woods
Honda manages a forest called Hello Woods in Motegi Town, Tochigi Prefecture, as a living museum where children
can discover and experience nature. Activities here focus on providing children with the opportunity to play and learn
in the forest. We have transformed the forest into a real-world classroom, providing children the freedom to play, to
discover the wonders and wisdom of nature, and to learn what they can do to help the planet.
Hello Woods is a forest of broadleaf deciduous trees in the Hakkouzan mountains, home to a diverse community of
plants and wildlife. Playing in the forest, children become interested in nature, discovering fascinating things about our
natural environment. It’s an experience with lasting educational benefits. Staff, called cast members or forest storytell-
ers, are always available to help the children learn as they play in the forest.
[URL] />The Fan Fun Lab
At the Fan Fun Lab in Twin Ring Motegi, Honda presents its environmental initiatives
through interactive exhibits, panels and films. The Fan Fun Lab aims to provide a space
where children—tomorrow’s leaders—can learn about the environment and deepen
their understanding about what they, as individuals, can do to conserve it. School
groups attend fun, educational workshops such as the New Energy Classroom, where
they can learn about the Honda FCX fuel cell vehicle. The design of the Honda FCX and
its importance in relation to global warming and next-generation energy sources are
explained in easy-to-understand terms. Some 1,151 people attended the New Energy
Classroom in FY2009.

as possible and constantly implements a wide variety of environmental initiatives.
Among its initiatives to reduce CO
2
emissions, the Center runs an advanced mi-
crogrid power generation and storage system.
A microgrid is a network of multiple, distributed power generation sources man-
aged to provide stable power on demand and capable of reducing both CO
2
emis-
sions and energy costs. With a view to maximizing energy efficiency, the Center implements centralized monitoring,
management and operation of the generation and delivery of electricity and heat.
In 2008, the company connected existing drive power sources, HVAC systems, electrical equipment and power

generation systems including the microgrid with a local area network (LAN), establishing a comprehensive manage-
ment system on the Center’s intranet. Visually intuitive, the system allows the associate in charge to view the energy
production and use status in real time and make appropriate decisions.
Microgrid management leads to high efficiency
The microgrid system of the Center comprises two cogeneration systems, two
sodium-sulfur (NaS) battery systems, an alternative energy production system that
derives power from waste fuel VOCs (volatile organic compounds) and a solar
power generation system. The two NaS battery systems are particularly advanced:
adding to the capacity of the 1,500 kW NaS Battery System No. 1, the 12,000 kW
NaS Battery System No. 2 began operation in September 2007 and, as of June
2009, is the world’s largest NaS battery system. These two systems are especially
helpful during the frequent power outages that occur due to the region’s numerous
electrical storms.
Among energy storage batteries, NaS batteries have an especially high charge
and discharge efficiency. They efficiently store power during those times of day
when energy is cheaper and help provide a consistent supply of power. This system also helps stabilize the Center’s
power supply during times of peak demand in the summer while reducing the burden on the local power infrastructure,
Aiming to be an R&D center with the world’s smallest environmental footprint the Automobile R&D
Center implements advanced environmental initiatives in three categories: reducing greenhouse gas
emissions, reducing output of harmful chemicals and using resources efciently. In particlar, to combat
the worldwide problem of CO
2
emissions, the Automobile R&D Center is working to reduce its CO
2
emis-
sions to 85% of the FY2001 baseline by 2010. One advanced alternative energy technology the company
is using to accomplish this goal is its microgrid power generation and storage system.

thereby contributing to society. An NaS battery system may also be used as a back up to solar-power generation systems
and other renewable energy sources, which typically have large fluctuations in the amount of power they generate.
Added to the 1,253 kW Cogeneration System No. 1 in April 2008, Cogeneration System No. 2 uses a gas turbine to
generate up to 7,000 kW. In addition residual fuel is used for power generation in VOC processing. The Center has also
increased solar power generation from 112 kW to 156 kW, allowing the microgrid to provide an optimal power supply
with low CO
2
emissions.
The total amount of power the Center uses is equivalent to the amount used by 30 to 40 thousand typical house-
holds; of this amount, the Center purchases 90% from the public utility and generates 10% in-house through alternative
energy. Going forward, the Center will continue to develop its microgrid system, aiming for the most environmentally
responsible method of operation possible.

Honda Environmental Annual Report 2009 : Case Studies and Supplementary Information
Honda Group companies case studies

In 1990, when Honda Engineering began its move from Saitama Prefecture to Tochigi
Prefecture and submitted a proposal for its water treatment facility, the company had
the idea of producing wastewater that was even cleaner than the water of the Shimanto
River on the island of Shikoku, a river famous in Japan for its cleanliness. The future site
of the company was in the town of Haga near the Nomoto River, an area of great natu-
ral beauty where people make the river part of their everyday lives. Tochigi Prefecture,
where local water needs to be appropriate for agricultural uses, has one of the strict-
est wastewater quality standards in Japan. Since Honda Engineering is engaged in the
research and development of manufacturing technologies, the wastewater it produces
changes on a daily basis and contains a wide variety of chemical substances. To deal
with this uniquely challenging set of circumstances, Honda Engineering has created a
leading-edge water treatment system.
Expanding its operations and increasing its water usage since its move from Saitama Prefecture, Honda Engineering has ad-
opted a new policy of recyling wasterwater instead of discharging it. Rather than discharge wastewater into the Nomoto River,
the company decided to make the water cleaner and reuse it in its own facility. Participating in the Green Factory project,
Honda Engineering established the goal of producing zero wastewater by the year 2030 in order to conserve water resources.
Since then, Honda Engineering has accelerated its efforts, introducing higher-level treatment equipment for both ordinary
(sewage, etc.) and industrial wastewater. Currently, the company is aiming for 100% recycling of water by 2010.
In pursuing this goal, in FY2009, Honda Engineering purchased 61,500 m
3
of water and exceeded the target to recycle
56,216 m
3
. Thanks to the savings achieved by purchasing less water and treating less wastewater, the investment in additional
equipment was recovered in two years. In February 2009, Honda Engineering stopped purchasing water for industrial uses
and discharging ordinary wastewater and expects additional savings to result.
Aiming for Japan’s cleanest wastewater and 100% recycling
In processing ordinary wastewater, Honda Engineering uses a biological treatment
method that utilizes 3,000 species of bacteria instead of treatment methods based on
physical chemistry. The company processes wastewater and sludge using proprietary

technologies, for which the company has registered over 10 patents. Honda Engineering
manages the bacteria with precision control, adding oxygen and nutrients with precision.
To select and control the bacteria that will help achieve the necessary water quality, the
company has established a treatment management and testing regime built upon many
years of testing and experimentation. In 1990, the company added two underground tanks
to the No. 1 Plant capable of processing 140 m
3
of ordinary wastewater per day. This
system was ahead of its time in the use of iron contactors, only the third private facility in
Japan to implement the technology. In 2004, Honda Engineering built a second ordinary
Due to the experiments it conducts in its R&D operations, Honda Engineering Co., Ltd. creates many
different types of wastewater on a daily basis. Honda Engineering treats all wastewater it produces to
comply with the strict water quality standards of the town of Haga, in which it is located, and has ac-
cepted the challenge of managing wastewater at the highest level of environmental responsibility. Thanks
to advanced devices, original innovations and Honda’s own patented technologies, Honda Engineering
has developed a proprietary water treatment system that is highly effective. Leading the way in solving
environmental problems and using water resources effectively, Honda Engineering is aiming to recycle
100% of the water it uses and produce zero wastewater by 2010.

per day, adding an ultrafiltration membrane separation process to
the biological process. Water made clean by the ultrafiltration membrane is further treated with activated charcoal, making it
appropriate for use as coolant water and for other uses in the factory.
Honda Engineering’s industrial wastewater treatment facility is capable of handling the wide variety of substances produced
by the company’s ever-changing research and development operations. Completed in 1997, the No. 1 Industrial Wastewater

Treatment Facility treats wastewater from electroplating machines. A water treatment product called Fabios was implemented, in
which microorganisms adhere to a fine fiber medium that may be exchanged. Completed in 2005, the No. 2 Industrial Wastewa-
ter Treatment Facility was one of the first private treatment facilities in Japan to deploy membrane technology. At the time, it was
believed that membranes could not be used to treat wastewater containing heavy metal ions, but Honda’s experiments proved
that if reaction processing, nitrification and denitrification were performed in advance, separation with ultrafiltration membranes
could be used. The system that Honda Engineering created transformed steps that had conventionally taken place in the latter half
of the treatment process into pre-processing steps. This industrial wastewater treatment facility has a daily processing capacity
of 160 m
3
. Today, to recycle industrial water, Honda Engineering further treats the water from this process with reverse osmosis,
which prevents small particles and ionized matter from passing through the filter, turning it into salt-free water suitable for human
consumption. Honda Engineering uses this water as coolant or toilet water.

At the Tochigi Factory, primarily responsible for manufacturing automobile en-
gine and powertrain parts, a new facility for research, development and manufac-
turing of powertrain components was completed on March 20, 2009. Known as
the L10 Plant, the new 10,000 m2 facility contains a production area on its first
floor and offices, meeting rooms and research laboratories on its second floor. A
unique, next-generation facility with a wide variety of environmental innovations,
the L10 plant is designed to be hospitable to associates and the local community
and the planet.
The new plant features a Honda-developed 12 kW solar power generation sys-
tem installed on a frame on the facility`s second floor—the second such system in
the Tochigi Factory complex. Powering the lights of the office and meeting rooms,
the system includes a display for real-time monitoring of the amount of sunlight
received and power generated. In addition, in two areas totaling approximately
400 m
2
, the roof is covered with Phyla nodiflora growing in white sand, providing
an attractive green appearance and thermal insulation.

Environmentally responsible HVAC and lighting
Green Factory initiatives at the Tochigi Factory’s new L10 Plant
The L10 Plant uses both a geothermal exchange pump and recycled waste heat from production to provide heat for
the HVAC system. The geothermal heat pump takes advantage of constant underground water temperatures to provide
heat, and additional heat is derived from the used coolant water of the forging press. Combined in a hybrid configura-
tion, these two heat sources help reduce the energy consumed by the facility’s HVAC system.
Lighting in the L10 Plant has also been designed for optimal efficiency. Sunlight is captured on the roof and directed
via prisms down a tube to provide natural light to the offices below. LEDs light the meeting rooms, using less energy
and providing a longer lifespan than incandescent or fluorescent lighting. The processing of water used in production
for reuse in toilets is another example of the environmental initiatives implemented at this plant.
The L10 Plant is designed for efficient conservation of energy and resources. Its attractive green roof, natural light-
ing system and people-friendly logistics help make it a hospitable environment for all associates. The environmentally
responsible design of the new L10 Plant makes it a welcome addition to the Tochigi Factory and the company.

The headquarters and factory of Tsuzuki Manufacturing are located about 30 min-
utes by car from Ueda Station in Sakaki, Hanishina District, Nagano Prefecture, in
a mountainous area near the Chikuma River. The company’s three plants in Nagano
mainly produce front suspensions, lower arms, damper forks, stator shafts and other
components for Honda automobiles, as well as gear shift spindles for Honda motor-
cycles.
In November 2006, Tsuzuki Manufacturing installed a solar power generation
system on the roof of its No. 3 Plant, which produces the rotor shaft for the Insight
hybrid vehicle. The company is aiming to reduce CO
2
emissions by 16.7% from the
FY2000 baseline by FY2011, and decided to make solar power generation part of
their strategy. In 2006, Honda became the first automaker to enter the solar panel industry, making the move an even
more natural fit. In addition, as a company seeking to gain the appreciation of local society, Tsuzuki believed solar
power was an ideal form of energy, since its use can contribute to environmental conservation.
In October 2006, Tsuzuki installed a 40 kW solar power generation system but ran into a problem that winter: snow
tended to linger on the panels, preventing them from generating electricity. Comparing the installation to others in the
region and analyzing the problem, Tsuzuki associates determined that they actually faced two problems. First, sunlight
being blocked by the surrounding mountains led to limited exposure of the panels to the sun and the resulting relatively
persistent snow accumulation. Second, at temperatures above 30°C, the panels were comparatively less efficient. The as-
sociates decided to enhance the system to achieve more efficient powergeneration.

Tsuzuki enhances solar power generation system
• Tsuzuki Manufacturing Co., Ltd.
Tsuzuki Manufacturing Co., Ltd. is a Honda afliate engaged in manufacturing of transmission compo-
nents and other important components for automobiles and motorcycles. In 1999, the company achieved
ISO 14001 certication and is implementing ongoing initiatives to help conserve the global environment.
After installing in November 2006 a solar power generation system, which produces electricity with zero
CO
2
emissions, the company went on to modify the system to maximize its performance.
Solar power generation system performance boosted 15%
To improve the performance of a solar power generation system, it is neces-
sary to concentrate sunlight. The hint that led to part of the solution of Tsuzuki
Manufacturing`s problem came in the form of reflective sheets lying in an apple
orchard behind the factory. Apples farms are numerous in Sakaki, and farmers put
out silver sheets in great numbers on the ground to reflect light onto the apples and
enhance their color. Tsuzuki Manufacturing associates thought to use these same
sheets to reflect light onto the solar panels. After deciding on the angle to use and
the overall design, in August 2007, associates created a frame to hold the sheets un-
derneath the four rows of panels. In addition, they added a reflective panel to the
wall whose angle could be adjusted on the spring equinox, summer solstice, autumn
equinox and winter solstice to take advantage of the different angles of the sunlight. When light hits this movable panel,
it is reflected onto the reflected sheets and from there onto the solar panels, and this dual reflection further concentrates
the light. The use of these reflective surfaces improves the performance of the system by 12%. On the wall with the
movable panel, associates changed the windows from frosted glass to glass with reflective film, to maximize the light
reaching the solar panels.
The orchard next to the factory provides a hint

Honda Environmental Annual Report 2009: Case Studies and Supplementary Information
New ideas inspired by environmental initiatives based on ISO 14001
As a result of these innovations, from December 2006 to November

2007, Tsuzuki Manufacturing saw a 34% increase in power generation over
the rated level of the solar panels, resulting in a reduction of approximately
22 tons of CO
2
emissions per year. In 2008, two years after implementing
the changes, the performance profile for the system had risen 20% as com-
pared to the previous year. In the months in which performance decreases
the most, June to October, the Tsuzuki Manufacturing system achieved a
9% increase in efficiency. In contrast, comparable systems in the region
logged a decline in performance for the same period of 0.9%. In the Tsuzuki
Manufacturing system, the increase in performance attributable to the cool-
ing system was 1.6%, to the reflective panels 12.0% and to the reflective
window film 1.4% for a total of 15.0%. To enhance the performance of
the solar panels themselves would have required a significant investment in
R&D. Instead, Tsuzuki Manufacturing demonstrated the viability of enhanc-
ing system efficiency through innovations after installation.
Within the factory, associates can easily track the power generation status of the rooftop panels via a monitor. The
innovations used to enhance system performance made an impression on the associates particularly because their
impact is readily appreciable. At Tsuzuki Manufacturing, each department develops energy and resource conservation
and other environmental initiatives based on ISO 14001, involving all associates in these efforts. Pursuing challenging
goals to conserve the environment can lead to new innovations, and the enhancement of solar panel performance by
Tsuzuki Manufacturing associates is an example of how simple ideas can lead to significant results.
To combat the panels’ lower performance at higher temperatures, Tsuzuki devised
and installed a system of hoses that wrap around the panels, distributing water through
small openings. The hose system provided the benefit of melting the snow and keep-
ing the panels in operation. The hose system provides water in the summer when the
temperature is above 30°C to cool the panels and in winter when snow falls to prevent
accumulation. Although on average in Sakaki it snows only 9.6 days per year, the snow
tends to accumulate, preventing the panels from operating for extended periods. Thanks
to this system, the amount of electricity generated during the hottest time of day (12:00

noon to 2:00 p.m.) went up 3.8%. To improve the performance of the cooling process,
associates added anti-clouding agents and surfactants to the water to prevent it from run-
ning only in narrow paths across the panels.

• Honda Cars Aichi Co., Ltd.
Associates at Honda automobile dealerships play an important role in reducing the environmental im-
pact of dealer operations through their ongoing efforts to reduce usage of electricity and gasoline. In
order to raise awareness of the importance of environmental footprint reduction measures among its
associates, Honda Cars Aichi has since 2006 participated in Team Minus 6%, a Japanese Ministry of the
Environment-supported initiative. All dealership associates are working together to reduce CO
2
emis-
sions.
“Team Minus 6%” reduces environmental footprint
Introduction of cool biz, warm biz practices
Cool biz, warm biz, a Team Minus 6% campaign, encourages businesses to create an en-
vironment in which people feel comfortable working with the air conditioner set at a higher
temperature in summer and the heating set at a lower temperature in winter. At first, some
thought it would be difficult to implement this program in the dealer showroom, as it would
mean not only setting air conditioners to eco mode in areas where customers are negotiating a
purchase or waiting for their cars to be serviced, but also allowing sales and front office staff to
go without neckties. However, Honda Cars Aichi used its enrollment in Team Minus 6% as an
opportunity to promote the importance of environmental conservation to its customers, who
in turn praised the company for its environmental stance. These measures, once considered
difficult to implement, are now broadly accepted.
Eco Drive workshops
Honda dealerships’ environmental impact reduction initiatives go beyond merely reducing

their own environmental footprint. They also take the opportunity presented through their safe
driving workshops to teach Eco Drive workshops, in which customers are instructed on efficient
driving practices that help reduce CO
2
output by reducing fuel consumption. In FY2008, Honda
Cars Aichi held two safe driving workshops at each of its 52 dealerships, totaling 104 workshops.
Of the customers who participated in these workshops, 506 were also taught the key points of ef-
ficient driving in Eco Drive classes.
