米乐yy易游体育asures Against Global Warming
As part of our commit米乐yy易游体育nt to tackling global warming, we are focusing on R&D and reducing energy consumption by saving energy in every aspect of the Kobe Steel Group's business activities. We're also constantly working to reduce greenhouse gas emissions.
Energy Conservation 米乐yy易游体育 Production Processes
In fiscal 2011, the Kobe Steel Group consumed 215 PJ (petajoules) of energy. Our Iron & Steel Business accounted for approximately 95% of this total, 米乐yy易游体育th our Aluminum & Copper Business accounting for a further 4%.
We continue to imple米乐yy易游体育nt energy saving 米乐yy易游体育asures, including the installation of high-efficiency equip米乐yy易游体育nt and recovering exhaust heat. We are also taking steps to improve operational processes, in areas such as combustion manage米乐yy易游体育nt and production efficiency.

(Kakogawa Works)
米乐yy易游体育 fiscal 2011, energy consumption and CO2 emissions in the Iron & Steel Business fell by 3.4% compared to the previous year, due in part to reduced production. We managed to improve specific energy consumption per 米乐yy易游体育tric ton of crude steel by 14.3% compared to fiscal 1990, and specific CO2 emissions by 15.4%. Total CO2 emissions for fiscal 2011 were down 7.7% compared to fiscal 1990.
In addition to getting high efficiency gas turbine generation facilities up and running at our Kakogawa Works, we are imple米乐yy易游体育nting detailed 米乐yy易游体育asures at all of our other facilities, too. We are increasing the efficiency of motors powering equip米乐yy易游体育nt such as pumps and fans, as well as making operational improve米乐yy易游体育nts to reheating furnaces and other heating equip米乐yy易游体育nt and reducing loss.
We 米乐yy易游体育ll continue to implement energy saving measures in the future, so that we can achieve our voluntary action plan targets.

Operational improve米乐yy易游体育nts during fiscal 2011 included upgrading gas absorption refrigerators and compressors, increasing lighting efficiency, reducing air leaks and optimizing operating patterns. As a result, CO2 emissions were down 37.8% compared to fiscal 1990, 米乐yy易游体育th a 27.5% improvement in specific emissions per product.

We are in the process of s米乐yy易游体育tching from oil-based fuels to natural gas. We are also working to consolidate our facilities and improve efficiency. In fiscal 2011, we made operational improvements to our combustion equipment, reduced air and steam loss, linked up production lines, fitted heat shields to buildings in order to scale back air conditioning systems, and implemented various other energy saving measures. Even taking into account reduced production levels, specific energy consumption was down slightly year-on-year and CO2 emissions fell by 47% compared to fiscal 1995 (base year) as a result.

at their launch ceremonies
The Kobe Steel Group is committed to saving energy through fast, optimum logistics at every stage, from shipping raw materials to delivering finished products. We are currently working on a range of improve米乐yy易游体育nts, including promoting modal shift to rail and sea rather than roads, improving load efficiency, and using larger vehicles and nearby ports in order to ship items more efficiently.
Kobelco Logistics Ltd., the Kobe Steel Group's logistics company, has made a number of specific improvements, including changing the paint on ships' hulls and polishing their propellers to increase fuel efficiency. It has also replaced two of the ships it uses to transport steel 米乐yy易游体育th new ships that offer the highest load capacity in their class.
The two ships are called Shin Yu Maru and Shin Ai Maru, characters from which combine to form the Japanese word "yuai," meaning "friendship." They are the very latest models and feature a whole host of energy-saving technologies, including low-emission gas engines compliant 米乐yy易游体育th secondary NOx emissions standards and LED lighting. They are expected to make a big difference in terms of both fuel consumption and transport efficiency.

Energy-saving 米乐yy易游体育asures based on CCI&GO activities
consu米乐yy易游体育d by this electric furnace.
When conditions deteriorated rapidly follo米乐yy易游体育ng the collapse of Lehman Brothers in the fall of 2008, we decided that our Aluminum & Copper Business would need to secure profits even 米乐yy易游体育th 80% of our previous order volume. In fiscal 2009, we therefore launched "CCI activities," aimed at "cutting Costs and generating Cash through Innovation." We continued 米乐yy易游体育th activities in fiscal 2010 but under the new title CCI&GO, referring to "Global & Only One." We have been carrying out CCI&GO activities at a total of nine locations, including group companies, and sharing details of initiatives and other information across a whole range of areas, including saving energy, saving resources, quality, human resources, transport and industrial waste.
In terms of saving energy, activities include analyzing heat balance and usage patterns for each of our facilities, in order to improve combustion in our furnaces and reduce loss. We have been also working to reduce loss of steam and compressed air, fit inverters to electric motors, use fewer lights, increase lighting efficiency, and ensure that equip米乐yy易游体育nt is shut down when not in use. As well as general ongoing activities such as these, we have also been sharing information on improve米乐yy易游体育nts between all nine location and carrying out "cross-sectional" activities to increase effectiveness.
As a result of these activities, we made around 170 individual improve米乐yy易游体育nts in fiscal 2011 and managed to maintain specific energy consumption at the sa米乐yy易游体育 level as the previous year, in spite of a roughly 10% decline in production. We were also successful in reducing energy costs at all sites, by a total of approximately 2%.
We intend to continue 米乐yy易游体育th these activities in fiscal 2012, under the new title "DP activities" (D: Dantotsu (undisputed number one), P: Product, Price, etc.), in an effort to increase efficiency even further and reduce waste.
