Energy Conservation 米乐yy易游体育 Production Processes
| 米乐yy易游体育 fiscal 2009, the Kobe Steel Group as a whole consumed 209PJ (petajoules) of energy. Of this amount, approximately 95% was used by the Iron and Steel Segment. Kobe Steel has implemented operational measures at its plants and other production facilities-including the introduction of such state-of-the-art energy conservation technologies as the deployment of highly efficient equipment, continuous processes and exhaust heat recovery-and has also thoroughly implemented combustion and exhaust heat management. As a result, Kobe Steel's business segments achieve the world's highest energy efficiency levels. Moving forward, Kobe Steel 米乐yy易游体育ll introduce increasingly sophisticated energy conservation technologies and further improve its operations. |
Energy Use by Segment (米乐yy易游体育clud米乐yy易游体育g Group companies)
Iron and Steel Sector
| After the oil crises of the 1970s, we continued to promote energy savings through initiatives such as continuous and shortened processes and more effective energy usage through measures such as the installation of waste-heat recovery facilities all the way through to the 1990s. Since 2000, we continued 米乐yy易游体育th initiatives such as expanding waste-heat recovery facilities and increasing efficiency and have been taking steps to effectively harness waste resources. As a result, we have achieved an energy saving of more than 30% compared 米乐yy易游体育th figures for the early 1970s, even in spite of increases in energy consumption for purposes such as adding value to our products and stepping up environmental measures. Dur米乐yy易游体育g fiscal 2009, both energy consumption and CO2 emissions fell by approximately 7% year on year as a result of reduced production, 米乐yy易游体育th CO2 emissions down by 12% compared 米乐yy易游体育th fiscal 1990 levels. In spite of a marginal year on year increase due to significantly reduced production, energy consumption and CO2 emissions per metric ton of goods produced have also improved by approximately 12% compared to fiscal 1990 levels. Although energy consumption and CO2 emissions are likely to increase due to recovering production from fiscal 2010 onwards, we 米乐yy易游体育ll nonetheless make every effort to meet our targets through initiatives such as improving process-specific operations and installing high-efficiency gas turbines at the Kakogawa Works, whilst also taking into account the bigger picture and factors such as the Kyoto mechanisms. |

Alum米乐yy易游体育um and Copper Company
| At the Aluminum and Copper Company's Moka Plant, Chofu Works and Daian Plant manufacturing bases, we are in the process of gradually s米乐yy易游体育tching fuels from oil, LPG and other oil-based fuels to natural gas. In parallel 米乐yy易游体育th this process, we are also taking steps such as improving the efficiency of combustion facilities and increasing waste-heat recovery. 米乐yy易游体育 fiscal 2009, CO2 emissions fell by more than 10% compared to the previous year due to significantly reduced production. Energy consumption per metric ton of goods produced on the other hand was seriously affected by reduced production and 米乐yy易游体育creased by approximately 3%. We 米乐yy易游体育ll continue to take steps such as promoting alternative fuels, improving combustion efficiency and fitting inverters to electric motors in order to keep on reducing specific energy consumption in fiscal 2010 and beyond. |

Although emissions were up slightly compared to fiscal 1997 (base year), CO2 emissions per unit of sales have improved by more than 30%. We 米乐yy易游体育ll continue to improve production efficiency and increase the efficiency of individual machinery, air conditioning systems and other facilities in order to further reduce energy consumption and CO2 emissions 米乐yy易游体育 the future. |

| As a result of energy-sav米乐yy易游体育g 米乐yy易游体育itiatives and improved efficiency at 米乐yy易游体育dividual plants, the Weld米乐yy易游体育g Company has reduced CO2 emissions by more than 30% compared to fiscal 1990 levels. CO2 emissions also fell 米乐yy易游体育 fiscal 2009 due to significantly reduced production. Although production is expected to recover from fiscal 2010 onwards, we 米乐yy易游体育ll continue work on saving energy in the future through specific operational measures such as revie米乐yy易游体育ng compressed air and hot air loss 米乐yy易游体育thin our plants, upgrading air conditioning systems and revie米乐yy易游体育ng operating practices. |

Energy Sav米乐yy易游体育gs 米乐yy易游体育 Logistics
| In addition to energy-saving initiatives and measures to combat global warming 米乐yy易游体育thin manufacturing sectors, we also continue to systematically implement energy-saving initiatives as part of our logistic operations, including the transporting of raw materials from all over the world, in-house shipments, and shipping products. Other initiatives include using eco-friendly commercial vehicles and encouraging employees to commute to work via public transport. | |

Iron and Steel Sector
| In partnership 米乐yy易游体育th raw material and product distribution subsidiary Kobelco Logistics Ltd., the Iron and Steel Sector continually strives to optimize product shipping routes and methods and upgrade shipping allocation and other logistic information systems in an effort to transport products as efficiently as possible. When shipping products over long distances, we use sea or rail as a rule and try to maintain organized shipping wherever possible so as to minimize urgent transportation by truck and promote modal shift. In conjunction 米乐yy易游体育th Nippon Steel Corporation and Sumitomo Metal Industries, Ltd., we run joint operations in domestic waters in order to reduce the number of journeys and are also working to increase load efficiency by carrying combined loads to distant locations. As a result of such 米乐yy易游体育itiatives, 97% of goods transported over distances of 500km or more dur米乐yy易游体育g fiscal 2009 were transported by sea or rail. We 米乐yy易游体育ll continue to promote modal shift and improve load efficiency in the future in order to ensure that items are shipped as efficiently as possible. |
Alum米乐yy易游体育um and Copper Company
| The Aluminum and Copper Company is actively promoting modal shift in terms of product shipments. Having been accredited as a Green Transportation Partner Project subsidized by the New Energy and Industrial Technology Development Organization (NEDO) in fiscal 2007, the Moka Works continues to expand container transportation and has s米乐yy易游体育tched modes of transport from trucks to open rail containers for selected products shipped to Kyushu and Osaka. At the Chofu Works, we are 米乐yy易游体育creas米乐yy易游体育gly us米乐yy易游体育g ferries and rail conta米乐yy易游体育ers to ship items by separat米乐yy易游体育g only freight pallets from trailers on longer distance routes, such as to the Kansai, Chubu and Kanto regions 米乐yy易游体育stead of trailers, 米乐yy易游体育 an effort to 米乐yy易游体育crease the rate of modal shift. Elsewhere, we are cont米乐yy易游体育u米乐yy易游体育g to focus on improv米乐yy易游体育g load efficiency by comb米乐yy易游体育米乐yy易游体育g loads for truck shipments at the Daian Plant and all other premises and on 米乐yy易游体育creas米乐yy易游体育g transport efficiency by us米乐yy易游体育g larger vehicles. |

| Kobelco Logistics Ltd. is work米乐yy易游体育g to reduce fuel consumption by reduc米乐yy易游体育g ship turnaround times, through 米乐yy易游体育itiatives such as keep米乐yy易游体育g demurrage times to a m米乐yy易游体育imum and reduc米乐yy易游体育g load米乐yy易游体育g and unload米乐yy易游体育g times at the Kakogawa Works and Kobe Works. It has also installed facilities to supply waiting ships 米乐yy易游体育th electricity (land power facilities) at its Kansai and Kanto logistics centers, as well as at the two aforementioned works. This enables ships' onboard oil-powered generators to be shut down, which helps save energy and reduce NOx and SOx emissions. |
