Life Cycle of ProductsMessage from the General Manager of the Environmental DivisionReduce the Environmental Impact and Contribute to Global Environmental PreservationOur products are environmentally aware and highly rated by many customers for their ability to provide acomfortable living environment and improve the product storage environment.On the other hand, we must admit that the products’ manufacturing and use inevitably has an impact on ourirreplaceable global environment and must thus ensure due consideration is made to reducing this impact.Responsibility is also demanded from enterprises for the whole of the product life cycle. We are facing a test interms of our attitude and management responsibility. We acknowledge the importance of establishing anenvironmental CSR response for surveys, data collection and management, and utilization concerning chemicalcomponents of products.With due recognition of these responsibilities, we will challenge the development of new technologies andbusiness innovation to reduce environmental impact as well as contributing to environmental preservation as oneof Earth’s citizens.As for "reduction of the environmental impact during product manufacturing", we will continue striving,domestically and overseas, toward energy conservation and waste reduction in plants and the adequatemanagement of chemicals.As for "reduction of the environmental impact of usage", we will strive to offer a range of eco-friendly products,namely, those friendly to the global environment and human health. For this purpose, we use advanced technologyto ensure energy conservation and industry leading noise reduction and try to use refrigerants free from ozonedepleting substances and other harmful material.Furthermore, in order to "reduce the environmental impact of logistics and disposal", our design gives dueconsideration to the life cycle from the developing/planning stage up to the product itself. There are also efforts toensure compactness and improved recycling efficiency by reviewing the packaging, providing resin materialmarking, and understanding and managing the chemical components of products, etc.Finally, we believe it important to establish a good relationship with the stakeholders around us through regionalenvironmental preservation activities and communications with regional residents.As a member of the Hitachi Group, we will take a leading role in environmental activities.Hitachi Air Conditioning Systems considers the environment through all stages ofproduct development and manufacture to after sales service.Hitachi Air Conditioning Systems feels it is the responsibility of the manufacturer to promote a reductionin environmental impact through all stages of the manufacturing process. From product planning, theadoption of materials, and energy conservation during use to the recycling of used products."What kind of product should we make?" Environmental problems are considered from the initialPRODUCT PLANNINGstages of product planning and determining the nature of our products. By identifying and tacklingenvironmental problems in the initial developmental stages, we are achieving good results.Haruki YamamotoDirectorDuring the design we have to improve overall performance and make a point of reducing noise andDESIGNincreasing the energy conservation performance of our Air Conditioners. We also believe choosingdurable but easily recyclable materials is an important part of improving environmental performance.An important issue in each of our factories is maximizing the reduction of the environmental impactfrom manufacturing. We are promoting activities such as a move toward zero waste emissions, energyMANUFACTURINGconservation and a reduction in CO2 emissions. This is a constant focus of our attention and an area ofcontinual daily improvement.Product packaging is also a key point when considering environmental impact and methods of packingEnvironmental Protection Action Guidelinesare continually subject to review to ensure an overall reduction in such impact. We are working towardsLOGISTICSabolishing styrene and reducing the amounts of cardboard and wood used. In addition, efforts made tominiaturize our products are also expected to improve logistical efficiency.“Environmental Activity Concept”For the future of the planet, we promote forward-looking activities and consider harmony with theenvironment in everything we do.We are constantly improving our products so that they are silent and highly energy efficient duringoperation. We have also adopted a new refrigerant with zero ozone depletion caused, in order to reduceUSEthe environmental impact.“Environmental Activity Guidelines”We promote environmental activities which focus on society, considering the health of thepopulation and the preservation and harmony of the global environment, to enable us to passon the irreplaceable global environment to the next generation.We are conscious of our influence on the global environment and striving to provide advancedproducts, systems, and services.We adopt recyclable materials through the manufacturing process and our product-recycling rate isAFTER USEincreasing each year. All components that require identification are labeled to indicate the materialsused. We also use a refrigerant recycling system that collects, processes and breaks down the refrigerantinto its separate elements and which will be used to increase the refrigerant recycling rate.Environmental Measures Implemented beyond compare by Hitachi Air Conditioning SystemsThe Refrigerant Recycling SystemWe promote activities that take recycling, resource and energy conservation, waste reductionand pollutant management into consideration.These activities are implemented in every stage of the manufacturing process from researchand development, design, and manufacture, sales and installation to after sales service.Equipment Disposal / Equipment Repair(Refrigerant Collection Contract)Customers / SuppliersWe conform to all environmental regulations. In addition, we have self-imposed rules; basedon a forward-looking attitude to minimize environmental impact.We use an environmental management system and promote environmental education in orderto implement continual improvement in environmental activities.3Environmental Report 2005FluorocarbonRecycling /Destruction FacilityHitachi Air ConditioningSystemsCollection / Accumulation /TransportationRefrigerant CollectionOperationsIn refrigerant collection, highpressure gas is handled bytechnical persons, operatingusing collection equipment,and collected in containers asdetermined by law.Refrigerant CollectionOperationsRecycling /Separation TreatmentEnvironmental Report 20054

Eco-Management 1Eco-Management 2If environmental activities are to achieve a firm objective, it is essential to establish more specific and effectivetargets. By setting up an eco-management system allowing individual workers to recognize the environment in theirindividual positions, workers can be motivated to more positive, smoother actions, paving the way for substantialachievements.Environmental Management StructureWe have established an Environmental Specialties Committee; ledby the General Manager of the Environmental Division, who wasappointed by the President. As overall policy, Hitachi AirConditioning Systems Group positively promotes wide-rangingenvironmental activities based on policies and measures decided bythe committee.Environmental Management SystemWe have organized an environmental management system based onISO 14001 as one of our environmental activities. We acquired ISO14001 Certification for both our domestic sites and three of theseven overseas sites. To confirm the implementation of theenvironmental management system and the results of theenvironmental performance based on ISO 14001, we are assessedyearly by an accredited external organization. Furthermore, anenvironmental audit is carried out by internal auditors who arecertified both inside and outside the company.In FY2004, Hitachi Air-Conditioning and Refrigerating Products(Guangzhou) of China newly obtained environmental ISOcertification. Certification is ongoing in production sites in Japanand overseas.Acquisition of ISO 14001 Certification Domestic Members of the Internal Environmental AuditorCertified SiteCertified OrganizationDate of AcquisitionShimizu WorksJACOOctober 1997 Overseas Certified SiteCertified OrganizationDate of AcquisitionTaiwan HitachiBSMIAugust 1997Hitachi Air ConditioningProducts (Europe)AENORMay 1999Hitachi Air-conditioning &Refrigerating Products(Guangzhou)Mainly China QualityAssurance AssociationAuditorsShimizu Works23Taiwan Hitachi49Hitachi Air Conditioning Products (Europe)GREEN21 Ver2Continuing from the previous year, GREEN 21 Ver 2 has beenimplemented. The evaluation criteria of GREEN 21 Ver. 2 are EcoManagement and Eco-Mind, Eco-Products, Eco-Factories,Stakeholder Collaboration, and Sustainable Business Models. Weclassified the criteria into eight categories to evaluate the activitylevel of the fiscal year concerned.The activity levels are evaluated with ratings of 0 to 5. Level 4 isthe target achievement level specified in the environmental actionplan of the Hitachi Group in FY2005, while level 5 is an activitylevel exceeding the action plan.FY2004 saw top rated achievements in GP categories (GP greenpoint), namely, 533GP. However, activity evaluation showed lowlevels of points in the categories of Eco-Products and SustainableBusiness Model; both in Japan and overseas. In addition, due todiffering legal regulations among countries, a difference in pointsamong sites is evident, particularly in terms of EcoFactories/prevention of global warming.Since achievement of the FY2005 target (640GP) is extremelydifficult simply by maintaining the current activity level, thepromotion of activities exceeding this latter is essential.“GREEN21 Version 2” ActivitiesSite concerned: Shimizu Works, Taiwan Hitachi, Hitachi Air Conditioning Products (Europe)Targets and Results in Green PointsGP Green PointsFiscal Year2002200320042005Target GP320426533640Result GP363461535Evaluation Criteria (8 categories / 53 performance indicators)Category3Main Contents of EvaluationShimizuWorksTaiwanHitachiHitachi AirConditioningProducts (Europe)AverageHitachi Air-conditioning & Refrigerating Products (Guangzhou)22Eco-Management— Environmental ManagementEnvironmental Management, Action Plan,Environmental Accounting70687069Total97Eco-Management — Risk ManagementSet Own Standard, Statute Compliance84968087Eco-MindTraining for Employees87819387Nature-Friendly ProductsProducts / Service Assessment, Green Purchasing, Measure for Logistics60425452Eco-Factories — Prevention of Global WarmingEnergy Conservation in Offices and Factories80392648Eco-Factories — Resource RecyclingWaste Reduction, Chemical Substance Management84595967Stakeholder CollaborationInformation Disclosure, Communication Activities, Community Activities94966685Sustainable Business ModelsPromotion of Sustainable Business Models45432839604524476535June 2004Environmental Management Structurein Hitachi Air Conditioning Systems (as of April 2005)PresidentTotalDirector of EnvironmentalDivisionEnvironmental Specialties CommitteeGeneral Manager ofEnvironmental DivisionEnvironmental DivisionChairperson: General Manager ofEnvironmental DivisionMember: Environmental Representativesof Each DivisionOffice: Shimizu Works EnvironmentalGroupSales DivisionShimizu WorksFacilities DivisionService Engineering DivisionLarge Tonnage Chiller DivisionEnvironmental SolutionDivisionOverseas Affiliated CompaniesTaiwan HitachiHitachi Air Conditioning Products (Brazil)Hitachi Air Conditioning Products (Europe)Hitachi Air-conditioning & Refrigerating Products(Guangzhou)Qingdao Hisense Hitachi Air-Conditioning SystemsHitachi Compressor Products (Guangzhou)Hitachi Industrial Machinery (Philippines)7Environmental Report 2005Service stations(19 stationsnationwide)FY2005 achievement levelEco-Management -Risk ManagementManagement DivisionAdministration DivisionStakeholder CollaborationBranches / Sales Bases10080Sustainable Business ModelsDivisionsGlobal Business DivisionEco-Management-Environmental ManagementReview scene of the Internal Environmental AuditEco-Mind0Large TonnageChiller SalesDivision, TsuchiuraEco-Factories -Resource RecyclingNature-Friendly ProductsFY2002FY2003FY2004Affiliated CompaniesEco-Factories -Prevention of Global WarmingHitachi Air Conditioning SEEnvironmental Report 20058
