Environmental Annual Report Honda 2009 Case Studies and Supplementary Information Environmental information disclosure Honda discloses its environmental policies and practices in the CSR Report, in the Honda Environmental Annual Report and on its website (http://world.honda.com/environment/). 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. 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 CO2 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 CO2 emissions manufactured at plants with the lowest per-unit CO2 emissions. Honda Group companies worldwide continue to advance a wide range of ini- tiatives for the reduction of environmental impact.

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. Principal noise/vibration reduction technologies • Engine noise reduction technology • Intake noise/radiant noise • Exhaust noise/radiant noise · High-rigidity cylinder block reduction technology reduction technology · High-rigidity crankshaft · High-volume, high-rigidity air · Noise-absorbing chamber · High-rigidity chain case cleaner · Long tailpipe silencer · Stiffener, integrated aluminum oil · High-volume, high-rigidity resonator · 2-layer heat cover pan chamber · Hood insulation · Engine compartment undercover Silencer Resonator chamber Air cleaner Chamber 4 Honda Environmental Annual Report 2009: Case Studies and Supplementary Information Reduction of in-vehicle VOCs 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. Case Studies Exhaust emissions Even cleaner Odyssey emissions The completely redesigned, fourth- generation Honda Odyssey was released in October 2008. It is available with a 2.4-liter Integrated cylinder head i-VTEC engine that combines reduced exhaust manifold precious metals content with enhanced Linear A/F sensor emissions performance. The latest model High-heat-resistanct O2 sensor features a newly developed integrated catalytic converter cylinder head exhaust manifold and an Under-the-floor catalytic converter 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. Designing the 3R’s (reduce, reuse, recycle) 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.
