Environmental information disclosure
The Honda Environmental Annual Report is published yearly It presents environmental corporate information,
including Honda’s policies and future direction with respect to the environment The report focuses particularly on
the results of the year’s initiatives in each management domain, and on progress made toward targets from the
point of view of Honda's corporate activities throughout its products’ life cycles Complementing the disclosure of
environmental corporate information, Honda’s website (http://world.honda.com/environment/index
html) provides further details about the results in each domain (for instance, environmental impact
data for each Honda facility), and also presents the history of Honda's environmental initiatives
By disclosing a wide range of information, we hope to facilitate communication and feedback,
thereby strengthening our environmental conservation initiatives going forward
Environmental annual report
The Honda Environmental Report is comprised of two parts: the Main
Report, which focuses on annual environmental initiatives, and the
Case Studies and Supplementary Information, available exclusively on
Honda’s web site, which covers specific initiatives in each of the
domains introduced in the report.

Editorial policy for the Honda Environmental Annual Report
Early in its history, Honda recognized that an involvement in efforts to combat various kinds of environmental problems was one of its
most important management priorities We publish the Honda Environmental Annual Report to inform the public about our environmental
initiatives over the preceding year This is the 14th edition of the Honda Environmental Annual Report, which was first published in 1988
As of 2011, Honda regards global climate change and energy issues as being particularly important among the many
environmental problems that exist today (see Page 6 for details.) To combat these problems, Honda is working to reduce
emissions of greenhouse gases resulting from its business activities and from the use of its products, and has set medium-term
targets for this purpose (see Page 8) Under our mid-term management plan, we have also formulated and are steadily
implementing environmental initiatives to combat other environmental problems (see Page 10)
We will continue to inform the public about these initiatives, and in particular about the progress we have made each year,
through the Honda Environmental Annual Report Other information, including details and data, are regularly posted on our
website, as indicated in Disclosure of Honda Environmental Information
Other key information disclosure
Honda’s environmental reports and website also contain corporate information other than that concerning the environment
Honda is continuously working to enhance communication with its stakeholders by making information about its various
activities easy to understand and encourages feedback Honda regards full communication with all stakeholders as essential to
further improving its activities, and welcomes feedback to this and all of the reports listed below

Driven by its philosophy of building products close to the customer, Honda has manufacturing operations in six
re-gions worldwide In FY2011, Honda delivered 27 million products to its customers around the world Always
con-scious of the environmental impact of its operations, Honda is working hard to take environmental
responsibility to ever higher levels around the world.
In 2006, Honda announced global CO 2 emissions reduction targets for 2010, the first announcement of its type
by a company in the automobile industry In 2011, we adopted “the Joy and Freedom of Mobility” and “a
Sustain-able Society where People Can Enjoy Life” as the Honda Environmental Vision Under this vision, Honda is
deter-mined to accelerate its global efforts to find solutions to climate change and the energy problem.

At the Saitama Factory, Honda has installed regenerative thermal oxidizers (RTOs)1 on its bumper coating line to reduce emissions of volatile organic compounds (VOCs) The RTOs enabled VOC concentrations to be reduced below the required standard while also reducing energy requirements through heat recovery, without changing the existing facilities We also succeeded in reducing the size of RTOs after discovering the leveling effect of activated charcoal on VOC concentrations These measures have reduced CO2 emissions by about 1,400 tons annually.

Wastewater treatment facilities at the Suzuka Factory were replaced
in 2010 By adopting an orthodox approach based mainly on biological treatment, we were able to minimize costs while achieving the highest treatment quality in the motor vehicle industry The new system can also treat wastewater from the new line in the coating plant, which is now using water-based paints as base coatings.

Ken Shiotani
Trang 19Water-based products have been used for middle and base coatings
on the No 1 Coating Line at the Suzuka Factory since 2000, which means that water-based paints were already beings processed in the old system
However, at that time, most of the coatings were still based on organic solvents The new No 3 Coating Line, in operation since 2009, has been progressively converted to the use of water-based products, which now make up 80% of the coating materials in wastewater from the coating plant Several treatment processes were considered, but eventually it was decided to use an orthodox biological treatment method, which
is relatively cheap to operate To meet the stringent environmental standards, a new tertiary treatment facility was also installed
3 The concept: wastewater treated to the same standard as industrial water, consistently and reliably
The goal of the project was to create a system that would consistently and reliably treat all wastewater treated and released locally to the same standard as industrial water, thereby ensuring low environmental loads at the Suzuka Plant In addition to raising the quality of treated water, Honda also wanted to improve maintainability, prohibit hazardous processes, and limit the amount of waste produced
In June 2007, the government of Mie Prefecture issued a notice requiring newly built treatment facilities to meet a total pollutant standard of chemical oxygen demand (COD)1 of 10mg/liter In 2006, the old facility had a wastewater COD level of 40mg/liter Honda’s goal was
to reduce this to 7mg/liter, which would be less than one-quarter of the old level and among the best in the motor vehicle industry
Wastewater from the Suzuka Factory includes oil-bearing wastewater, which contains cutting oil from mechanical processing equipment; coating wastewater from the coating plant; general wastewater, such as domestic wastewater from kitchens and toilets, and rainwater Hiroshi Sano, an engineer with the Facilities Department, recalls that there used to be separate treatment facilities for wastewater from mechanical processing equipment and the coating plant “The treatment facility for coating

The Hamamatsu Factory has been transformed into a powerhouse
of automobile production Located in the middle of the Aoi Plant, this advanced environmentally responsible factory was completed in September 2010 Features include rooftop gardens and the biggest solar power system at any Honda factory The factory is also equipped with the world’s most efficient air supply system, thanks to the installation of
a new compressor in time for the opening of the new facility As a result, Hamamatsu won the compressor efficiency award at the Honda Green Conference in December 2010.
