JFE Steel's Activities to
Prevent Global Warming
―
Stepping into the first fiscal year of the Kyoto Protocol
―
We have engaged in a variety of activities to date in order to adhere to the Voluntary Action Program of the Japan Iron and Steel Federation (JISF). Entering the first fiscal year of the first commitment period of the Kyoto Protocol, we will use technological development and facility investments to focus to the greatest degree possible on this arena, in line with our reduction of energy consumption (and CO2emissions). Also, we will
aim to fully accomplish the JISF Voluntary Action Program by using the Kyoto Mechanisms as a complementary measure.
Furthermore, we will do our part to assist in the reduction of CO2emissions through supplying high
performance steel products such as high tensile steel sheets, which contribute to improvements in fuel consumption for automobiles. And on the international stage, by converting our steel production process to employ energy saving technology that meets the highest global standards, we will contribute to the reduction of CO2on a global scale.

Source: The Japan Iron and Steel Federation Transition in Energy Consumption
by the Iron and Steel Industry in Japan
Since the 1970s, we have worked towards CO2
reduction through technological development and the introduction of a variety of different kinds of equipment. For example, we use gases generated from various processes for fuel and electric power required in our steelworks and we also assiduously collect and efficiently use emission gasses and exhaust heat. Thanks to these efforts, we have achieved a 36% reduction in unit energy from 1973 to the present, achieving world-class efficiency in energy consumption.
Energy Saving Activities
We have been increasing production in response to stronger demand for highly functional steel products from customers mainly in the automobile, electric appliance, and shipbuilding industries. As a result, compared to the year ended March 1991 level, crude steel production had increased 30% by the year ended March 2008.

History of Energy Saving Activities
Special Feature
Though crude steel production had increased 30% by the year ended March 2008 when compared to the year ended March 1991, we were able to keep the increase in CO2emissions to 5.0%. And, using the
most sophisticated equipment and technology in the world resulted in a 19% reduction in the amount of CO2
emissions involved in producing one ton of crude steel (unit CO2emissions).
The CO2emissions for each fiscal year presented here are different from the numerical values given in the business report for the previous fiscal year (year ended March 2008). The reasons for the change in values and the difference of this report from the CO2emission levels officially announced in the Law Concerning the Promotion of the Measures to Cope with Global Warming are presented on page10.
Though crude steel production increased 30% in the year ended March 2008 when compared to the year ended March 1991, we were able to keep the increase in energy consumption to 5.6%. Additional efforts to conserve energy through technological development and equipment investment resulted in dramatic streamlining, with an 18.7% reduction in the amount of energy consumption required to produce one ton of crude steel (unit energy).

Special Feature
We actively promote the development of high performance steel that is lightweight, highly efficient, and long lived through superior technological prowess. For example, because automobiles and ships can be made stronger and lighter with high tensile steel sheets (HITEN), it becomes possible to increase safety and improve fuel efficiency. Also, using high performance electrical steel sheets enables a high level of efficiency in electrical machinery and transformers.
Thanks to this high performance steel, the calcu-lated level of CO2emission reduction for the year ended March 2007 was 7.86 million tons for the entire group of companies in the JISF.

Transition of Non-energy Origin GHG Emissions by the Iron and Steel Industry in Japan
Non-energy origin
(million t-CO ) Methane
The amount of CO2 emissions is calculated by multiplying the amount of energy used for each energy type (coal, electricity, byproduct gases, etc.) by its CO2
coefficient. Because the coefficient values were completely revised, our energy origin CO2emissions
values have also changed for this fiscal year.
As a result, the emissions figures for year ended March 2007 reported in the Environmental Report for the year ended March 2008 was 55.8 million tons and the figure reported in the Environmental Sustainability Report for this year is 58.6 million tons.
(Note 1) Reasons for the revision of energy conversion coefficients: revision of electric energy conversion coefficient and the standard thermal output amount in the Ministry of Economy, Trade and Industry's General Energy Statistics (conducted every five years)
(Note 2) Reasons for the revision of CO2emissions coefficients: in the National Greenhouse Gas Inventory Report of Japan (May 2007), which was compiled under the supervision of the Ministry of the Environment and reported to the UN, the CO2emissions coefficients for some fuels were revised and reviewed from the benchmark year. The electric power CO2 emissions coefficient was also revised from the benchmark year to fit the new figures.

The CO2emissions amount officially reported in this Environmental Sustainability Report handles energy-origin CO2calculated under Japan Iron and Steel
Federation's Voluntary Action Program.
However, according to the Law Concerning the Promotion of the Measures to Cope with Global Warming (Global Warming Measures Law), the reporting of all greenhouse gases stipulated in the Kyoto Protocol is required. This is why there is a difference between the two figures. The actual figures for the year ended March 2007 are shown in the graph to the right.

International Contribution
Using energy conserving technology of the highest international standards, we are involved in the following international actions in the fight against global warming.
Japan and China held the Japan China Steel Industries Conference on Exchange of Advanced Technologies on Environmental Preservation and Energy Saving. In December 2007, prominent experts on Japanese steel, including JFE Steel, conducted diagnoses regarding environmental preservation and energy saving at three steelworks in China.
The APP *1steel task force (chaired in Japan) is
promoting CO2reduction in seven countries through environmental preservation and energy conservation.
IISI *2provides a framework for CO2reduction by
introducing superior modern operational technology and energy conservation technology in steel industry centers across the world in the short term, and
International Activities to Prevent Global Warming
promoting the development of innovative steel production technology in the long term.
Along with other major Japanese steel companies, JFE Steel is asserting to APP and IISI the effectiveness of the Sectoral Approach, a powerful strategy for reducing CO2emissions on a global scale from 2013
onwards (Post-Kyoto Protocol).
*1APP: Asia Pacific Partnership (an Asian-Pacific partnership concerned with clean development and weather) was launched in July 2005 with the participation of Australia, China, India, the Republic of Korea, and the United States. (From October 2007, Canada, the seventh nation, will also take part.) The goal of APP is to take on issues such as climate fluctuation and energy security. It set eight target areas, including steel, and established a task force for each field, composed of members from the public and private sectors. It is currently conducting activities in each field.
*2IISI: The International Iron & Steel Institute is composed of approximately 180 leading steel manufacturing corporations in territories including Japan, the USA, the EU, Russia, India, Brazil, and Korea. It covers almost all of the world's crude steel production needs. In their October 2007 board meeting, they decided to use the Sectoral Approach internationally.

CO2 reduction from advanced technology research and
development in the Japanese steel industry
➠➠
Note : The Sectoral Approach is a CO2reduction method that applies efficiency indices (example: unit CO2per ton of crude steel) across the entire world. The indices are categorized by each sector, such as steel or electrical power. Because the Approach is based on efficiency indices, it is easy for developing countries such as China and India to participate. It is a reliable method of reducing CO2backed by technology.

Each company in the JFE Group has been aiming to receive ISO 14001 certification in order to promote voluntary and continuous environmental activities. Three operating companies with production facilities have all received ISO 14001 certification, either for individual works or at the whole company level. In March 2008, Steel Research Laboratory of JFE Steel received ISO 14001 certification. Many affiliates of the operating companies have also been aiming to receive the certification. The JFE Group will continuously extend the number of accredited companies/produc-tion facilities.
Promotion to Receive ISO 14001
At the JFE Group, the environmental auditing has been conducted on the basis of ISO 14001, and with the aim of enhancing environmental management quality. As for the environmental auditing on the basis of ISO 14001, external inspection is made by certification authorities, while internal auditing is conducted by qualified employees who not only have taken the auditor-training course offered by an external institution but also have experience in environment related work
As for the environmental auditing with the aim of enhancing environmental management quality, internal auditors of the head office's audit department and environmental experts of the head office's environmental management division conduct auditing on issues centering on the environmental management status and compliance system with environment related regulation of each of the operation facilities and affiliated companies.
Environmental Auditing
The JFE Group conducts environmental education at all levels to deepen the understanding of each employee and encourage individual efforts to improve the environment as part of regular work. In each operating company, environmental education is incorporated in training programs for new employees and promotion, and also includes annual programs at each level, covering social trends related to environmental problems, the significance of the environment to JFE and measures being taken by the company, the responsibility of individual employees, and the importance of environmental management.
Environmental Education
In 2002, the JFE Group established a common group-wide set of "Green Purchasing Guidelines" for purchases of office supplies and parts/materials for production.
Green Purchasing
In outline, the Guidelines specify
•Adequate study of required quantities
before purchase to minimize purchased amounts. •Consideration of environmental loads
over the entire life cycle of final products, in addition to price, quality, delivery schedules, etc.
•Requests for and cooperation with environmental protection efforts of suppliers on a daily basis. Examples of green purchasing:
•Stationery, office equipment •Recycled oil, solvent containers,
packaging materials,
electric/natural gas/hybrid vehicles, etc.

Efforts to Restore Marine Environments
using Steel Byproducts
Marin Block®
– Seaweed and coral growing beds –
The world's first Marine Block®is a completely new
product made only from the source materials of CO2
gas emissions and steel byproduct that is generated in steel works converters. The material is the same calcium carbonate found in shells and coral, which blends well with marine life. Because of this, it aids the recovery of coral reefs, reduces CO2 in gas emissions,
and helps in the fight against global warming.
Frontier StoneTM& Frontier RockTM – Artificial rock material replacing natural crushed rock –
This is an artificial rock material made out of steel byproducts from blast furnaces and converters in steel works. Frontier StoneTMis an artificial rock material with a particle size of 300 mm or less, and Frontier RockTMis a large artificial rock material. They can be used as construction work materials at harbors and ports, and are excellent at supporting sea life such as seaweed.
Marine Stone®
– Modifying dredge soil –
Modifying dredged soil with Marine Stone®mixture can
turn dredged soil into banking material and has an effect on phosphorus adsorption, a cause of eutrophy.
Frontier RockTM
Seaweed growing on Marine Stone®
JFE Steel is dedicated to developing applications for steel byproducts and expanding their usability. Products created out of steel byproducts are expected to play a part in preserving the ocean as functional materials.

We are running verification tests around Ishigaki Island and Miyako Island, and Indonesia as well, and are already seeing corals that have grown larger than 10 centimeters in diameter on Marine Blocks®. I want to use this technology to preserve not only coral reefs, but to help preserve the wider natural environment as well.
Recovery of coral reefs with Marine Block
®Substrate with coral larvae attached is placed on Marine Block® 15 months after installation (young coral is growing

Coral reefs are spread out in great quantities across ocean areas from the tropics to the subtropics. In addition to functioning as mating and feeding grounds for a variety of organisms, they serve an important role as natural breakwaters for island countries. However, the coral reefs of the world are facing a severe crisis because of problems like the inflow of sediment from land, an explosive increase in predators such as the acanthaster (also known as the crown-of-thorns sea star), and the increase in
ocean water temperatures due to global warming. Coral reefs are being damaged through whitening caused by increasing ocean water temperatures, and we are involved in the development of technology to help coral reefs reclaim the seas. By combining our Marine Block®as a growing base for
coral with the coral larvae substrates devised by professor Okamoto of the Tokyo University of Marine Science and Technology, we are working towards coral reef recovery.

JFE Engineering constructs environmental management systems in line with the function and activities of each production center as our part in the fight against global warming.
In the office area, we do what we can to promote energy conservation by using a highly efficient Clathrate Hydrate Slurry (CHS) Heat Storage Air-conditioning System, turning off lights during lunch breaks, and keeping unused computers turned off. In the year ended March 2008, we installed solar street lights at the Tsurumi Engineering and Manufacturing Center.
In the production divisions, we have employed measures such as saving electricity by reducing factory
