Environmental Management

Environmental Philosophy and Strategies

The JFE Group’s environmental philosophy and strategies target the development of innovative technologies and international cooperation aimed at protecting the global environment.

Environmental Philosophy

The JFE Group puts top priority on protecting and enhancing the global environment to maintain its business in harmony with the environment, ultimately for the prosperity of society as a whole.

Environmental Strategies

  1. Reduce the environmental impact of all businesses
  2. Contribute through technologies and products
  3. Conserve resources and energy
  4. Communicate with society
  5. Facilitate international cooperation

Framework for Environmental Management

The JFE Group Environmental Committee, chaired by the president of JFE Holdings and operating under the JFE Group CSR Council, sets goals for environmental protection, monitors the progress of such initiatives and works to improve the Group’s overall environmental performance. Key issues for corporate management such as climate change are deliberated at the Group Management Strategy Committee as well and reported to the Board of Directors. The board oversees environmental challenges by discussing the reported material. Additionally, specialized committees set up by JFE Group operating companies and affiliates implement specific activities.

Material Flow

JFE Steel works to reduce the environmental impact of its iron and steelmaking processes, including through the effective use of resources. The company recycles 93.5% of the water it uses for production and uses 99.7% of its co-products, such as iron-steel slag. In addition, 100% of co-product gas generated during production is reused as fuel for reheating slabs, generating power for internal use and supplying power to the public.

Climate Change Mitigation

Basic Approach

The JFE Group’s business involves steel manufacturing, which emits large amounts of CO2. Therefore, climate change is a serious management concern from the viewpoint of the Group’s business continuity. The steel business, which accounts for 99.9% of the Group’s CO2 emissions, has developed many technologies for saving energy and reducing CO2 emissions and has adopted them in its steel manufacturing process. As a result, CO2 emission intensity in its steel manufacturing process is the lowest in the world. The JFE Group also develops and possesses many other eco-friendly products and technologies such as high-performance steel materials that contribute to the customer’s energy saving and power generation using renewable energy.

Going forward, the Group will continue to achieve technical advances in products and services while at the same time expanding the uses of technologies it has accumulated over many years throughout its global operations, all part of its contribution toward mitigating climate change.

CO2 Emissions of the JFE Group

JFE’s CO2 emissions are mainly generated by its steel business. However, beyond reducing CO2 emissions from steel production process, each company sets specific targets corresponding with their operations to further save energy and reduce CO2 emissions.

CO2 Reduction Initiatives

Initiatives towards CCU/CCS

JFE Steel

In order to reduce CO2 emissions from the steel manufacturing process, JFE Steel is actively engaged in the development of new technologies to separate and recover CO2 from blast furnace gas. This is in line with the JISF’s COURSE50 project (CO2 Ultimate Reduction in Steelmaking Process by Innovative Technology for Cool Earth 50), which focuses on hydrogen reduction of iron ore and separation and recovering of CO2 from blast furnace gas. JFE Steel has been working on developing for practical use a physical adsorption technology for separating and capturing CO2, which could then be fed to carbon capture and storage (CCS).

More recently, JFE Steel has also initiated R&D into the effective use of CO2 separated and recovered from blast furnace gas and is one of the first domestic steel manufacturers to explore this field. JFE Steel is a participating member of NEDO*1 projects for the development of next-generation thermal power generation technologies / development of basic technologies for next-generation thermal power generation / development of CO2 utilization technology project, and as such, it is working on an initiative together with RITE*2 to develop new technologies for separating and recovering CO2 from blast furnace gas and utilizing it to synthesize methanol (CH3OH).

In this project, JFE Steel is developing technologies that lower the cost of CO2 separation and recovery that meets the objectives of CCU and process design for effective CO2 utilization. The expertise in CO2 separation and recovery technologies it has acquired through the COURSE50 project is applied to CCU.

CO2 Reduction Initiatives

JFE Engineering

JFE Engineering strives to reduce CO2 emissions in society through our clients and their daily operations by providing them with eco-friendly products and technologies, including those that harness renewable energy and energy-saving products.

For example, if all of the renewable energy-related plants that JFE Engineering has constructed by FY2018, including those currently under construction, were in operation, their estimated contribution* to CO2 reduction would mount up to 4.12 million tonnes per year. Furthermore, JFE Engineering strives to reduce its own CO2 emissions in accordance with the Energy Conservation Law, from its head office, branch offices, and works.

In FY2018, CO2 emissions increased by approximately 120 thousand tonnes compared to the previous fiscal year due to the merger with Tokyo Waterfront Recycle Power. The JFE Engineering group has been achieving the reduction target set by the Energy Conservation Law every year since FY2015. Companies of the group each have their own energy saving initiatives that are appropriate for their businesses to make their contribution in reducing overall CO2 emissions.

  • * For renewable energy power generation plants, the characteristics of each plant is taken into consideration while estimating their CO2 emissions.

Contribution to CO2 Emission Reductions by Renewable Energy Plants (FY2018)

JFE Shoji offices in Japan work to reduce their use of energy and paper as well as strictly manage waste separation. Energy consumption has been lowered significantly by observing days when employees are encouraged to leave work on time, prohibiting night work, and introducing pinpoint lighting. In FY2018, as in the previous year, the company has achieved more than a 50% reduction in energy consumption compared to FY2001.

In addition, the company has introduced video conferencing systems in offices worldwide to reduce printed reference materials and domestic and international business trips.

Resource Recycling Solutions

Initiatives for Resource Recycling Solutions

Initiatives for Resource Recycling Solutions

The JFE Group is involved in establishing a recycling-oriented society through a variety of initiatives.

Steelworks promotes the efficient use of raw materials, water, and other resources in the process of iron and steelmaking in addition to encouraging the application of recycled resources such as used plastics for blast furnaces.

Moreover, we are striving to more efficiently use co-products generated in the iron and steelmaking process through initiatives such as the international recycling of steel scrap.

In the engineering field, in addition to constructing and providing customers with waste incineration plants and plants for treating sludge, we are developing a waste recycling business and an energy supply business to offer resource recycling solutions.
