Scenario Analysis

Tools and Methods

Scenario analysis is performed to provide an accurate understanding of climate-related risks and opportunities and assess implications to the current business strategy, thereby enabling the organization to establish business strategies that reflect this assessment. We selected the following two scenarios by considering the fact that our business has potentially high exposure to the impacts of climate change.

Both scenarios are based on those developed by the International Energy Agency (IEA). Analysis is conducted under the assumption that a uniform carbon price is implemented in major emitting countries toward the realization of the 2°C target.

For the long-term scenario analysis, we set our goal as achieving carbon neutrality by 2050. We conducted risk assessments that take into account the prospect of achieving the 2°C scenario and the necessity of super-innovative technology for the 1.5°C scenario (IPCC 1.5°C Special Report) in steelmaking for carbon neutrality by 2050.

*4If prices of carbon differ from country to country, there will be a gap in international competitiveness between countries that impose strict CO₂ emissions regulations and less strict regulations. This will result in carbon leakage where CO₂ emissions of a strict climate policy country are reduced due to decreased production and investment, while production at and investment to other countries with laxer emission constraints increase, in turn increasing the CO₂ emissions in those countries. One reference scenario, SDS, assumes that carbon pricing is implemented in developed countries and some developing countries. By taking this into account, we formulated the 2°C scenario based on the assumption that a uniform carbon pricing is introduced to major emitting countries to push toward achieving the target of two degrees.

Scope of Business and Period for Analysis

This analysis covers the following businesses: the steel business by JFE Steel, the engineering business by JFE Engineering, the trading business by JFE Shoji, and businesses carried out by some of the other Group companies. The period covered is up to 2050.

Relevance with JISFʼs Long-term Vision for Climate Change Mitigation

The JFE Group's steel business is led by its operating company, JFE Steel. JFE Steel is a member of the Japan Iron and Steel Federation (JISF), which has committed to the achievement of a low carbon society with the target year of 2030. In November 2018, the JISF also formulated and published the Long-term Vision for Climate Change Mitigation for 2030 and beyond. JFE Steel played a central role in the formulation of this long-term vision. The vision represents the industry's challenge toward realizing zero-carbon steel and lays out the prospect of achieving the 2°C scenario for steelmaking and necessity of super-innovative technologies to achieve the 1.5°C scenario. Furthermore, on February 15, 2021, the JISF announced the "Basic Policy of the Japan steel industry on Japanese government," which declares that the Japanese iron and steel industry will boldly accept the challenge of realizing zero-carbon steel.

The JFE Group's scenario analysis is intended to ensure resiliency in our Group's business strategy during the intermediate stages of these long-term challenges.

Results of Scenario Analysis

For the JFE Group, 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. We have actively addressed the risks by applying these technologies to steel manufacturing and have also successfully reduced CO₂ emission intensity to the lowest level worldwide. We will continue to develop processes to reduce environmental impact further while at the same time seeking to turn this challenge into an opportunity for addressing climate change issues by deploying the technologies we have fostered across the globe.

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 view the current challenges as an opportunity and are contributing to solving the climate change problem. Automobiles are expected to become lighter in weight while the number of electric cars increases. We will support this by improving the functions of the JFE Group's high tensile strength steel sheets and electrical steel sheets. In addition, we will help reduce our carbon footprint by further disseminating renewable energies and implementing recycling initiatives as well as energy conservation.

To achieve the long-term goal of the Paris Agreement, to keep the global average temperature increase well below 2°C compared to pre-industrial levels and to strive to limit it to 1.5°C, the Group will continue to develop and disseminate new technologies and contribute to the prevention of global warming. We will also support national resilience by providing steel for social infrastructure and construction to address the emerging risks associated with the growing severity of meteorological disasters.

Overview of a Scenario Analysis Assessment

Timeframe: Mid-term ⇒ until 2024, 2030 ⇒until 2030, 2050 ⇒2050 (final)

FOCUS Key Factor (1) Decarbonization of Iron and Steelmaking Process

We are developing innovative technologies to emerge as the pioneer in realizing a decarbonized society. With a strong financial base to meet investments for implementing innovative technologies, we are significantly contributing to the transition to a decarbonized society.

Mid-term, 2030

JFE Steel has been committed to developing energy-saving technologies toward increasing the efficiency of the iron and steelmaking process and decarbonization. These initiatives have helped JFE Steel acquire technologies that realize the world's top energy efficiency in iron and steelmaking. To further push ahead with decarbonization, the Company will enhance the development of innovative ironmaking processes such as COURSE50 and ferro coke, which are expected to reduce the carbon footprint through hydrogen reduction and CCS.

Mid-term, 2030, 2050

COURSE50 applies hydrogen reduction technology and CCS to reduce CO₂ emissions by about 10% and 20%, respectively, through each technology, for a total reduction of about 30%. The first facility is expected to come online by 2030, followed by the implementation of other plants by 2050, corresponding with the timing for upgrading blast furnace facilities. Ferro coke is a technology for significantly reducing CO₂ emissions by improving the reduction rate of iron ore put into blast furnaces. In addition to these technologies, we will push forward to establish a hydrogen reduction ironmaking technology which we will aim to put it into practice after 2030 in order to realize the ultimate goal of creating zero-carbon steel.

We consider implementing innovative technologies as critical and will advance with this strategy together with the government. Furthermore, we have a sufficient financial base to meet necessary investments.

A medium-scale pilot plant with the capacity to produce 300 tonnes of ferro coke per day was constructed in the Fukuyama district of the JFE Steel West Japan Works, and experimental runs began in October 2020.

Example of Developing an Innovative Technology: Ferro Coke Production Process

Example of Developing an Innovative Technology: Ferro Coke Production Process


In the long term, we will develop carbon recycling blast furnaces (CR blast furnaces), hydrogen steelmaking, and electric furnaces while striving to achieve carbon neutrality by 2050, as stated in the JFE Group Environmental Vision for 2050. In particular, we have been focusing on a technology that combines a CR blast furnace with CCU. This is a super-innovative technology that targets net zero CO₂ emissions by drastically reducing CO₂ emissions from the blast furnace process, maximizing its ability to efficiently produce high-grade steel in mass volume, and enabling CO₂ reuse in the blast furnace. The remaining CO₂ that cannot be fully reused in the furnace will be further reduced by manufacturing basic chemicals such as methanol.

Cost competitiveness will be maintained in case uniform carbon pricing is introduced across all countries.

Mid-term, 2030

Various approaches to carbon pricing have been introduced around the world, and in Japan as well the analysis for carbon pricing such as carbon taxes and emissions trading has started toward achieving carbon neutrality by 2050. In Europe, a border adjustment tax is also being discussed.

If uniform carbon pricing is introduced to major emitting countries, the increase in operating cost will be reflected reasonably on the price of steel products both in Japan and overseas, thus maintaining the Company's cost competitiveness. In addition, since CO₂ emissions per unit of steel production is the lowest of all competing materials, steel retains its superior position in cost competitiveness.

On the other hand, the introduction of carbon pricing in a manner that is biased toward certain regions, industries, or countries such as Japan would have a major impact on the JFE Group and particularly on its steel business as this would further increase the current price of electricity, which is already high in Japan compared to other countries. It may cause the Company to lose its cost competitiveness and may even inhibit innovation and hinder the realization of carbon neutrality. As carbon pricing is introduced, we will need to monitor emerging trends closely in order to see whether it will truly contribute to growth.

FOCUS Key Factor (2) Increased Need for Effective Utilization of Steel Scrap

To achieve carbon neutrality, we are focusing on high-grade steel manufacturing and raising efficiency by applying our industry-leading electric furnace technology. Furthermore, we will open up opportunities for the entire JFE Group by expanding the use of our electric furnaces, increasing the use of our electric furnace construction technology, and expanding scrap logistics.

Mid-term, 2030, 2050

The JISF predicts that the demand for crude steel will continue to grow as the world's population increases and the economy develops and that both the blast furnace and electric furnace methods will be indispensable as major steelmaking processes (JISFʼs Long-term Vision for Climate Change Mitigation). To achieve carbon neutrality, we need to expand the production of steel products using the electric furnace method, which emits less CO₂. For this to happen, we need to work on technologies that improve the productivity of electric furnaces and address the constraints in producing high-grade steel products. We must also work on technologies that increase the amount of scraps used in converter furnaces.

The JFE Group is viewing the increase in demand for electric furnace steel as well as the world-wide increase in the amount of scrap generated as an opportunity, and it will enhance its electric furnace steel production while applying its engineering technology for constructing an entirely cutting-edge, energy-saving electric furnace facility with the ultimate goal of opening up other business opportunities. Moreover, the Group will advance the development of technologies to utilize scrap and increase the industry-wide use of this material.

Meanwhile, expanding the use of scrap will bring about an increase in logistics for distributing it, and this will provide an opportunity for JFE Shoji to expand its logistics business.

FOCUS Key Factor (3) Change in Demand for Automotive Steel

The shift to EVs is accelerating as new and stricter environmental regulations are being introduced globally at a faster pace. Demand for electrical steel sheets for EV motors as well as special steel is increasing as global car sales rise. The increase in the intensity of high tensile strength automotive steel sheets contributes to further weight reductions.

Mid-term, 2030, 2050

The trend of increasing electric vehicles has given rise to rapidly expanding demand for electrical steel sheets used in EV motors. JFE Steel has already marketed the JNE series of non-oriented electrical steel sheets, used in building motors, as part of its eco-product lineup. It also commands a strong share of the market.

On the other hand, it has been pointed out that an increase in EVs may lead to a decline in the amount of special steel used in engine components. The amount of this type of steel, used in hybrid vehicles and electric vehicles, is 80% and 60% of gasoline cars, respectively. We believe that the risk level for this matter, however, is low since car sales are expected to increase even under the 2°C scenario and total demand for special steel for cars is increasing.

Nonetheless, the situation for EV remains the same in terms of strong demand for weight reduction of body structure. JFE Steel has developed a cold-rolled steel sheet boasting 1.5 GPa-grade tensile strength as an eco-product and has put it into practical use as an automotive steel sheet. With its high strength, the product can significantly reduce the weight of a car frame. In response to customer needs for more environmentally sound options, we intend to expand its application and further increase its strength, thus dramatically reducing CO₂ emissions from cars in motion.

Steel demand will increase due to renewed interest in its highly recyclable quality, essential for decarbonization.

Mid-term, 2030, 2050

Steel is a highly recyclable material that can be reborn as many different products over and over again with no loss in its intrinsic quality. In the future, public resource recycling is expected to increase toward establishing a decarbonized society. We believe that the high recyclability of steel will gain attention once again in light of this transition.

Effect of trend to use multi-materials is limited.

Mid-term, 2030, 2050

Aluminum and carbon fiber reinforced plastic are potential alternative materials for reducing the weight of cars. It has been pointed out, however, that the production cost of these materials and the amount of CO₂ emitted throughout their life cycles is higher than those of steel. Therefore, under the 2°C scenario, which assumes the introduction of a carbon price, the price differential between steel and alternative materials will be larger. Under this scenario, while the trend of using multi-materials may show some progress for luxury cars, their use would be limited for economy cars. Moreover, considering a situation in which all panels used for doors and other parts of a luxury car were changed to aluminum, the effect on weight reduction could be expected to be 5% of all materials used in luxury and economy cars together. Multiplied by the number of cars produced, the impact over the total demand for automotive steel can be assumed to be limited.

In the meantime, JFE Steel has developed a multi-material structure that uses a small amount of fiber resin to maximize steel quality. In this new structure, a highly ductile, strong adhesive resin is sandwiched between a body part made of an ultra-high strength steel plate and a part made of a thin steel plate. This structure is capable of further reducing the weight of automobile frame parts and also improving collision safety performance.

We will continue developing and proposing various products and technologies that meet customer needs.

FOCUS Key Factor (4) Increase in Demand for Solutions to Enhance Decarbonization

Contribution through the provision of solutions (renewable energy power generation, Multisite Energy Total Service, recycling business, carbon-recycling technologies and energy-saving steel technologies)
【 Renewable Energy Power Generation 】

Mid-term, 2030, 2050

Demand for power generation plants using non-carbon emitting renewable energies is expected to increase. The JFE Group engages in designing, procuring, constructing, and operating biomass*1, geothermal*2, solar*3, *4, and onshore wind power generation plants in its engineering domain.

We will also work on offshore wind power generation, which the Japanese government has positioned as one of the pillars of its Green Growth Strategy to achieve carbon neutrality by 2050. JFE Engineering will drive this by entering into the business of manufacturing seabed-fixed structures (monopiles, etc.). JFE Steel will contribute by increasing the supply of large and heavy steel plates, and JFE Shoji will assist by establishing SCM, which includes information sharing between Taiwan, who is leading the offshore wind power generation market, and East and Southeast Asian countries, which are future regions of demand. We will also work on the O&M*5 that makes maximum use of Group resources.

Furthermore, from the perspectives of resource recycling and effective use of resources, we are making efforts to increase power output at waste processing facilities. JFE Engineering is striving to develop a fully automated operation*6 to facilitate higher power output at incinerators.

(2020: six facilities  2021: additional four facilities are scheduled. More to follow.)

Moreover, we are utilizing renewable energy as the main power source for our retail electricity business*7 and in helping to establish and operate regional electricity retail companies*8*9,focused on local production and consumption of electricity based on renewable energy.

(Amount of contribution to CO₂ reduction resulting from renewable energy power generation: FY2020: 9.65 million tonnes per year  FY2024: 12 million tonnes per year  FY2030: 20 million tonnes per year)

【 Multisite Energy Total Service 】

Mid-term, 2030, 2050

In addition to the conventional service of optimizing energy use for single sites, JFE Engineering offers the Multisite Energy Total Service (JFE-METS)*1, which optimizes energy use for multiple sites through centralized management. We realize overall energy savings and CO₂ reduction by analyzing energy consumption at multiple sites and achieving total optimization by installing and operating energy-related equipment at each site to circulate energy throughout the network, including remote locations.

*1The JFE Engineering Corporation's JFE-METS (Japanese only)

【 Recycling Business 】

Mid-term, 2030, 2050

We are working to reduce the use of new fossil fuel-derived materials by recycling waste plastics and food wastes. In waste plastic recycling, in addition to the conventional recycling of plastic containers and packaging, we are actively engaged in the so-called bottle-to-bottle business, in which we recycle finished PET bottles into new PET bottles, demonstrating a complete resource recycling model for reducing CO₂ emissions. In food recycling, we generate methane gas from disposed food wastes to create renewable energy (fuel gas and electricity). JFE Engineering undertakes the construction of recycling plants*1 from design to procurement and construction as well as operation, and J&T Recycling Corporation operates a plastic recycling business.

Industry-wide decarbonization cannot be achieved only through technical developments in the manufacturing process alone. Therefore, we believe that demand for CCU and CCS facilities will increase as they facilitate the efficient use and storage of CO₂. JFE Engineering is able to undertake the entire process of building CCU and CCS facilities from design and procurement to construction.

*1 The JFE Engineering Corporation's Recycling

【 Carbon-recycling Technologies 】

Mid-term, 2030, 2050

JFE Engineering is working on a technology that uses CO₂ from exhaust gas and waste plastics, collected and separated using its own technology, to produce synthesis gas (CO + H2) that can be used as raw materials for chemical products. Since waste plastic is used as a source of hydrogen and energy, the company is able to achieve the carbon recycling of CO₂ and chemical recycling of waste plastic at the same time. We intend to commercialize this technology in 2024 as an EPC (Engineering, Procurement, Construction) product, and we also anticipate using it in our own businesses.

(Amount of contribution to CO₂ reduction made by the carbon recycling technologies: FY2024: 0 million tonnes per year  FY2030: 1 million tonnes per year)

【 Energy-saving Steel Technologies 】

Mid-term, 2030

From the perspective of the steel industry, there is space for disseminating eco solutions (energy-saving steel technologies) in nations such as China, where close to 50% of the world's crude steel is produced, and India and ASEAN countries, where further growth in production is expected. The potential CO₂ reduction achieved by internationally transferring and disseminating advanced energy-saving technologies widely used in Japan will exceed 400 million t-CO₂ world-wide. Japan is estimated to contribute to the reduction of approximately 80 million t-CO₂ in FY2030 through these technologies.

FOCUS Key Factor (5) Unstable Raw Material Procurement due to Increased Occurrence of Climatic Hazards

Ongoing initiatives to address the issue, such as alternative procurement and dispersed supplier bases, and increasing plant capacity.

Mid-term, 2030

In Australia, our major source country for raw materials, the occurrence of typhoons is predicted to double. We may be vulnerable in terms of continuous production and suffer a loss if production and shipping are interrupted for too long.

To address this issue, we are promoting alternative procurement and dispersed supplier bases.

[ Alternative procurement and dispersed supplier bases:]

Respond to disaster by carrying out spot procurement from China's port stocks, increasing procurement from closer source countries such as Russia and Indonesia and front-loading the purchase and/or increasing the purchase contract of different brands from outposts in unaffected regions of Australia. Also, use the stock and external yard of the Group company Philippine Sinter Corporation.

The decarbonization in the steelmaking process is expected to lead to a diversification of the required raw materials. We will take into account the risk of climate change for these materials also and work to establish diversified procurement sources.

FOCUS Key Factor (6) Damage to Production Bases and Offices Caused by Climatic Hazards

Measures against flood and drought in progress; impact of flooding caused by rising sea levels can be addressed with current countermeasures.

Mid-term, 2030

We are taking action to minimize damage under the assumption that typhoons and heavy rains will become stronger and that the occurrence of disasters comparable to the torrential rain in western Japan in 2018 will rise. We have currently invested approximately 6.5 billion yen for disaster prevention at steelworks and strengthened drainage facilities and other assets. About 3.5 billion yen of separate investment has already been made to prepare for water shortages at steelworks by installing desalination facilities at some of the steelworks. Although no severe drought disaster has struck since the 1994 disaster, we are preparing to minimize any damage even if the frequency of occurrence should increase.

All steelworks are exposed to the risk of floods associated with rising sea levels because of their location in coastal areas. The estimated sea level rise by 2050 is 20 to 30 cm (70 cm by 2100 if the impact of climate change manifests itself at the highest level.) We believe that current measures against storm surge, which generates more sea level rise, are sufficient to address the risk. However, we will continue analyzing climatic hazards going forward so as to prepare for the changing circumstances.

FOCUS Key Factor (7) National Resilience

Contribute to infrastructure enhancement with products such as high-strength H-shaped steel and steel pipe piles, hybrid tide embankments, and permeable steel slit dams.

Mid-term, 2030

The JFE Group takes seriously the increased frequency and severity of recent climatic hazards in Japan. Also, the daily life of the Japanese citizenry is being exposed to a heightened risk of danger. The JFE Group defines its mission as promoting disaster prevention and mitigation as well as national resilience to maintain vital infrastructure that are essential to daily life and economic activities.

The JFE Group will gather its collective energy to protect key structures from earthquakes using structural steel such as high-strength H-shaped steel and steel pipe piles as well as steel sheet piles. It will also help to reinforce embankments that are prone to bursting and provide disaster prevention products such as hybrid tide embankments*1 and permeable steel slit dams, in addition to reconstructing infrastructure.

【 Hybrid Tide Embankments 】

Hybrid tide embankments are made of steel and concrete. Because of their hybrid structure, they require shorter construction time and less space.

Concrete blocks for hybrid tide embankments are precast at a JFE Group factory, while steel pipe piles for foundations are installed at the construction site, thereby reducing the time required for on-site construction by about 60%. This arrangement does not require large amounts of materials, equipment, or workers on site, so it does not interfere with other construction work. Furthermore, compared to a conventional embankment structure, the land area occupied by the embankment can be reduced by about 80%, saving considerable space. We will continue to apply and advance our technology to further contribute to disaster prevention in the region.

【 Permeable Steel Slit Dams 】

A permeable steel slit dam is a steel pipe structure installed in a river to trap debris flows.

Made of strong steel pipes to withstand the impact of driftwood and huge debris, it has large openings to let water and sediment to pass through, which prevents the water level from rising upstream during floods and also ensuring that debris does not flow downstream. Since it does not block the flow of water, unlike a dam, it can be shaped to the slope of a riverbed to protect the ecosystem. The JFE Group is working to expand the use of permeable steel slit dams by reducing installation costs and shortening the construction period through structural innovations.
