Climate Change (Climate Change Mitigation)

Basic Policy

As an enterprise engaged in iron and steel manufacturing, which emits massive volumes of CO2, the issue of climate change is a critical managerial concern from the perspective of business continuity. Our steel business, which emits 99.9% of the Group’s total CO2 emissions, has been developing various technologies for saving energy and reducing CO2 emissions. Applying these to steel manufacturing has successfully reduced CO2 emission intensity to the lowest level worldwide.

Furthermore, the JFE Group has developed and maintained a variety of eco-friendly products and technologies, including high-performance steel materials that help save energy when customers use them, as well as renewable energy power generation.

We will continue to develop and promote the widespread use of these processes and products while at the same time seeking to turn this challenge into an opportunity to address climate change issues by deploying the technologies we have fostered across the globe.

The JFE Group's Medium- to Long-term Vision

Aiming to Reduce CO2 Emissions by 20% or More by FY2030 and To Be Carbon Neutral After 2050

The JFE Group intends to increase sustainability through solutions that address global climate change issues while restructuring its business to respond to developments in the environment facing the steel business. We regard this year to be a landmark year to further reinforce our efforts to tackle the issues of climate change, and we are actively promoting initiatives for reducing CO2 emissions with the targets set up as follows:

JFE Group's Target for Reducing CO2 Emission

Towards 2030
  • In the steel business, which accounts for most of the JFE Group’s CO2 emissions, we are exploring feasible scenarios with the aim of reducing CO2 emissions in fiscal 2030 by 20% or more compared to fiscal 2013, maximizing the use of the best available technologies and innovations.
  • JFE continues to share the Japan Iron and Steel Federation’s commitment to a low-carbon society and to play an active role. At the same time, JFE has launched a new project team to reduce our CO2 emissions as much as possible for an individual company, and will start examining various measures to achieve our targets.
Towards 2050
  • In line with the social transformation to establish carbon-free infrastructure over the long term, JFE will strive to be carbon neutral within the JFE Group as soon as possible after 2050.
  • JFE is carrying out research and development to be ready to show a lineup of carbon neutral technologies in its business processes well ahead of 2050.

Energy Savings and CO2 Reduction in Iron and Steelmaking

JFE Steel

Initiatives to Save Energy and Reduce CO2

JFE Steel has always aggressively pursued CO2 reduction and energy savings, including the introduction of energy-saving equipment.

Energy Consumption and CO2 Emissions in FY2019

Energy consumption and CO2 emissions in iron and steelmaking are greatly influenced by production volume. To accurately assess the effects of improvements due to operational technologies and capital investments, JFE Steel is working to reduce its intensity (energy consumption and CO2 emissions per unit of production) and related energy-conservation activities.

JFE Steel’s crude steel production was 26.73 million tonnes in FY2019, up 1.6% from FY2018 and up 13% from FY1990. However, thanks to ongoing energy-saving activities, energy consumption was down 8% and CO2 emissions were down 10% from FY1990.

The company’s energy consumption intensity in FY2019 was 19% below the FY1990 level at 23.2 GJ/t-steel, while CO2 emission intensity was down 18% to 2.03 t-CO2/t-steel. The results prove the success of JFE Steel’s energy-saving activities in recent years, including capital investments in energy conservation and promotion of energy conservation through the visualization of the reheat furnace fuel basic unit.

CO2 Reduction Initiatives

JFE Steel

Initiatives toward CCU/CCS

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 such as for the development of next-generation thermal power generation technologies, development of basic technologies for next-generation thermal power generation, and development of CO2 utilization technology, and 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 use of CO2. The expertise in CO2 separation and recovery technologies it has acquired through the COURSE50 project is applied to CCU.

JFE Engineering

JFE Engineering strives to reduce CO2 emissions in society through its 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 FY2019, including those currently under construction, were in operation, their estimated contribution* to CO2 reduction would mount up to 4.13 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 and has been achieving the reduction target set by the Energy Conservation Law every year since FY2015. And JFE Engineering’s Yokohama head office was presented with the Yokohama Global Warming Countermeasures Award for FY2019 in recognition of these initiatives. 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 (FY2019)

JFE Shoji

Under the environmental strategies formulated in 2001, JFE Shoji offices in Japan have consistently worked to reduce their use of energy and paper as well as strictly manage waste separation.

Efforts to cut energy consumption such as leave-on-time days, prohibition of night work, and pinpoint lighting have become firmly rooted. In FY2019, reductions in environmental impact were primarily achieved by improving the working environment through 5S activities, reducing power consumption by replacing computers, and promoting activities to raise operational efficiency by introducing robotic process automation (RPA).

JFE Shoji has also sought to raise awareness of environmental activities by creating a pocket card listing environmental strategies, fiscal year targets, and environmental initiatives related to office and trading activities. The card has been distributed to all employees.
