Environmental Annual Report
Advancing operations in regions
6
Driven by its philosophy of building products close to the customer, Honda has manufacturing operations in six
di󰮏erent regions worldwide. In FY2010, Honda delivered 24 million products to its customers around the world.
Always conscious 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 became the world’s rst 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 e󰮏orts
to even higher levels. As a global manufacturer, Honda 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 initiatives for the reduction of environmental impact.

Environmental annual report
The Honda Environmental Annual Report is issued in two parts.
The second part, titled “Case Studies and Supplementary Informa-
tion,” focuses on specic initiatives in each of the domains intro-
duced in this report, and is available on the website.
Environmental information disclosure
Information focusing on annual initiatives Comprehensive environmental information

The Honda Environmental Annual Report is published yearly. It presents environmental corporate information, in-
cluding 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 (da.
com/environment/) 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 strength-
ening our environmental conservation initiatives going forward.
