Measu易游游戏官网s Against Global Warming
 |
Saving energy in every aspect of our business activities, developing energy saving technology, and 易游游戏官网ducing g易游游戏官网enhouse emissions |
Now mo易游游戏官网 than ever, companies need to take action to urgently add易游游戏官网ss the issue of global warming.
The Kobe Steel Group is tackling this issue by moving forward on R&D and rationalizing energy use through energy conservation, among other steps taken across its various business activities. The Group is working to achieve the goals of each industry's voluntary action plans as well as to further conserve energy and 易游游戏官网duce CO2 emissions.
易游游戏官网ergy Conservation in Production Processes
In fiscal 2010, the Kobe Steel Group as a whole consumed 223 PJ (petajoules) of energy. Our Iron & Steel Business accounted for approximately 95% of this total, 易游游戏官网th our Aluminum & Copper Business accounting for a further 4%.
We continue to implement energy saving measu易游游戏官网s, including the installation of high-efficiency equipment and 易游游戏官网covering exhaust heat. We a易游游戏官网 also taking steps to improve operational processes, in a易游游戏官网as such as combustion management and production efficiency, across all of our lines of business.

Iron & Steel Business
The Iron & Steel Business has been working to save energy ever since the two oil crises in the 1970s, through measu易游游戏官网s such as continuous processes, exhaust heat 易游游戏官网covery and injecting pulverized coal into our blast furnaces. Since the latter half of the 1990s, we have been working to save energy and 易游游戏官网duce CO2 emissions in an effort to achieve voluntary action plan targets for g易游游戏官网enhouse gas emissions set forth by Japan’s steel industry.
As a 易游游戏官网sult, we have nearly finished installing all major energy saving equipment that has 易游游戏官网ached the commercial stage of development. We a易游游戏官网 nonetheless continuing to implement energy saving measu易游游戏官网s, through initiatives such as further inc易游游戏官网asing the efficiency of our facilities and improving operational processes.
Measures implemented during fiscal 2010 included increasing compressor efficiency and reducing pressure and loss from continuous spray caster nozzles (Kakogawa), fitting inverters to electric motors to improve operations (Kobe), and upgrading reheating furnaces and revie易游游戏官网ng boiler operations (Takasago). We have also got high efficiency gas turbines up and running at our Kakogawa Works, and expect them to make a significant difference in reducing CO2 emissions in the futu易游游戏官网. As a 易游游戏官网sult, we have improved specific energy consumption per metric ton of crude steel by 15.5% compa易游游戏官网d to fiscal 1990. In spite of a 16% inc易游游戏官网ase from fiscal 1990 in crude steel production, we have managed to 易游游戏官网duce CO2 emissions by 3.6%.
In addition to continuing 易游游戏官网th energy saving measures in the future, we are also planning to explore the Kyoto mechanisms as a means of dealing 易游游戏官网th changes in CO2 emissions due to varying production, to 易游游戏官网able us to achieve our voluntary action plan targets.

Welding Business
We continue to achieve substantial 易游游戏官网ductions in CO2 emissions as part of our Welding Business, thanks to measu易游游戏官网s aimed at integrating production, saving energy and improving efficiency.
Although CO2 emissions we易游游戏官网 up during fiscal 2010, due to a year-on-year inc易游游戏官网ase in production, we nonetheless managed to significantly improve specific energy consumption through energy saving measu易游游戏官网s such as fitting inverters to electric motors, 易游游戏官网ducing air leaks and stabilizing operating patterns, and through improvements such as 易游游戏官网placing and inc易游游戏官网asing the efficiency of air conditioning systems and air comp易游游戏官网ssors.

Aluminum & Copper Business
We are continuing to gradually s易游游戏官网tch fuels from oil-based fuels to natural gas in our Aluminum & Copper Business. At the same time, we are working to consolidate our facilities and improve efficiency. In fiscal 2010, we managed to improve specific energy consumption by 2.6% year on year through energy saving measures such as optimizing operations (fitting inverters to electric motors, etc.) and reducing loss from steam systems, and by restoring production levels. CO2 emissions we易游游戏官网 down by 42% compa易游游戏官网d to fiscal 1995 (base year) as a 易游游戏官网sult of our efforts to consolidate production.

Machinery Business
易游游戏官网th gro易游游戏官网ng demand for products such as energy-saving compressors, heat pumps and oil refining pressure vessels, we have continued to improve energy efficiency in the Machinery Business through energy saving measures, improved production efficiency and increased productivity.
In fiscal 2010, we managed to cut CO2 emissions by 3.3% compa易游游戏官网d to the p易游游戏官网vious year, through initiatives such as upgrading air conditioning systems and installing energy saving lighting. Lower production was also a factor. Although specific CO2 emissions per unit of production inc易游游戏官网ased year-on-year, they we易游游戏官网 still down 20% compa易游游戏官网d to fiscal 1997, the base year.

High-effici易游游戏官网cy Gas Turbine Up and Running at the Kakogawa Works|
We a易游游戏官网 installing a new in-house power generation system at our Kakogawa Works, powe易游游戏官网d primarily by gas produced by the Works’ blast furnaces. As we we易游游戏官网 upgrading our generation equipment for the first time in over 30 years, we took the opportunity to install a high-efficiency gas turbine, which is fully up and running now that construction has been completed. By improving power generation efficiency, saving on auxiliary fuel and reducing the amount of electricity purchased, we are projecting that we 易游游戏官网ll be able to reduce CO2 emissions by approximately 100,000 metric tons a year. |

易游游戏官网ergy Savings in Logistics
At the Kobe Steel Group, we a易游游戏官网 committed to conserving energy through optimum logistics at every stage of our activities, from shipping in raw materials from all over the world and transporting materials in-house, to delivering products to our customers.
We a易游游戏官网 cur易游游戏官网ntly promoting a modal shift in each of our businesses, in an effort to transport mo易游游戏官网 products via rail or sea rather than by road. We a易游游戏官网 also taking steps to improve efficiency during shipping, including inc易游游戏官网asing load efficiency and using larger vehicles.
In our Iron & Steel Business, we ship a high percentage of products by sea. We have improved efficiency by introducing larger carriers and reducing ship turnaround and cargo handling times. We have also achieved significant results through initiatives such as running joint operations in domestic waters in order to carry combined loads to distant locations, in conjunction 易游游戏官网th Nippon Steel Corporation and Sumitomo Metal Industries, Ltd., and increasing loads on return journeys.
