Climate Change

Policies and Basic Approach

How we respond to climate change and increasingly frequent and severe natural disasters – whether through initiatives such as the Sustainable Development Goals (SDGs), the ratification of the Paris Agreement at the United Nations, or other initiatives – is one of the most pressing issues of our time. Businesses must also play their part, and it is becoming increasingly important for companies to act responsibly in supporting the creation of a sustainable society.

The material issues ("Materiality") identified by Mitsui include "secure sustainable supply of essential products", "enhance quality of life", and "create an eco-friendly society", and our Environmental Policy stipulates that we will pursue the kinds of business that will help us act to reduce greenhouse gas (GHG) emissions, as well as mitigate and adapt to climate change. We have positioned climate change as one of the key themes of our sustainability management in our Medium-term Management Plan 2023. Moreover, we position technological innovation in environment and clean tech as one of the core strategic fields, and are working to pursue and expand investment opportunities in these areas.

We have set targets that aim to contribute to the goals of the Paris Agreement and Japan's own medium-term GHG emission reduction targets. Through our global and wide-ranging business activities, we will contribute to the development of economies and societies in many countries across the world and to solutions to the global challenges we face, such as mitigating and adapting to climate change.

Mitsui presented its climate change initiatives and "Roadmap to Net-Zero Emissions" at the Mitsui & Co. ESG Day held on December 3, 2021. Please refer to the link below for more information.

Governance System for Climate Change Response

We have positioned addressing climate change as a key management issue. Basic management policy, business activities, and corporate policies and strategies that concern climate change are planned developed, and advised on by the Sustainability Committee, an organization under the Corporate Management Committee.

The Sustainability Committee is structured so that its activities are appropriately supervised by the Board of Directors, and matters discussed by the Sustainability Committee are regularly discussed and reported to the Corporate Management Committee and the Board of Directors.

Scenario Analysis Policy and Process

Since declaring our support for the TCFD recommendations in December 2018, we have been engaged in a step-by-step scenario analysis process to enhance the resilience of our strategy by responding flexibly to changes in the global business environment. Traditionally, business units have analyzed risks, countermeasures, quantitative impact, etc. for their selected businesses and discussed them at the Sustainability Committee; however, in response to its growing importance, we have integrated scenario analysis into the formulation process for the business plan starting the fiscal year ending March 31, 2023. By incorporating scenario analysis into the business planning process, which is approved by the Board of Directors after reporting and deliberation by the Corporate Management Committee, the results of scenario analysis are confirmed and deliberated by management and reflected in the business plan and business portfolio strategy.

Selected Scenarios

We are conducting scenario analysis in short- (0-1 year), medium- (1-10 years), and long-term (10-30 years) timeframes up to the year 2050. We conduct scenario analysis of transition risks*1 and opportunities with reference to the scenarios set out in the World Energy Outlook (WEO) published by the (International Energy Agency) IEA. In addition, with reference to the RCP (Representative Concentration Pathway) used by the IPCC (Intergovernmental Panel on Climate Change), Mitsui has conducted analysis of investment assets above a certain value by surveying the impact of physical risks*2 based on natural disasters that have occurred over the last five years.

*1. "Transition risks" refer to risks caused by changes in policy/legal regulations, technology development, market trends, market evaluation, etc.
*2. "Physical risks" refer to the risk of physical damage caused by increases in natural disasters and abnormal weather arising from climate change.

  • IEA Stated Policies Scenario (STEPS): Scenario that reflect the current policy targets of each country
  • IEA Sustainable Development Scenario (SDS): Scenarios needed to uphold the Paris Agreement, which seeks to keep global warming within 2.0°C (and further pursue efforts to limit the temperature increase to 1.5°C) of the pre-Industrial Revolution level
  • IPCC RCP 8.5 scenario: Scenario in which the world's average temperature rises by around 4.0°C by 2100

We are considering expanding our analysis and disclosure to the 1.5°C scenario, in addition to the 2.0°C scenario outlined above.

Major Risks and Opportunities Associated with Climate Change

Mitsui is engaged in a wide range of business in countries and regions around the world, and we view the diverse risks and opportunities presented by climate change as important factors that we must consider when formulating our business strategies. We are identifying the short-, mid-, and long-term risks and opportunities that accompany climate change, and we review them periodically. We also review each segment in response to changes in the macroenvironment and trends, and adjustments in our business portfolio, along with other changes in the internal and external environment, and reflect them in our business strategy in a timely manner.

Transition Risks Policy and Legal Risks
  • Shift to the use of low-carbon-emission or decarbonized energy due to various national and regional policies (changes in energy and power mix)
  • Government-imposed restrictions on greenhouse gas emissions, with carbon taxes and cap-and-trade emissions-credit schemes

Transition Risk Assessments

We use multiple climate change scenarios for the selected business to assess the impact of transition risks on financial planning and business strategies, and use the results to investigate necessary countermeasures.

Selection of Business for Scenario Analyses

In consideration of scale of business operations and climate change impact, upon categorizing business as "high", "medium" or "low" priority, we have selected "high" priority business as targets for scenario analyses.

Selection of Business for Scenario Analyses

Results of Scenario Analysis

The results of scenario analysis for the ten businesses selected for this study are shown below. The scenarios referred to in the scenario analysis are organized into Current Policy and Transition Scenarios as follows.

  • Current Policy Scenario: A scenario in which current climate related initiatives of each country are maintained, demand (mainly in emerging countries) for fossil fuels and other resources that emit GHGs remains to a certain extent, and business practices which could impact climate change continue, resulting in higher risk of severe disasters and the need to respond to such risk (STEPS, etc.).
  • Transition Scenario: A scenario in which there is a slowdown in demand for fossil fuels and other resources that emit GHGs, and growth in demand for corporate activities that contribute to building a sustainable society, such as an increase in demand for renewable energy and other resources, as a result of the international development of advanced initiatives and systems to address climate change. The risk of severe disasters remains to a certain extent (SDS, etc.).

The impact of the Current Policy Scenario and the Transition Scenario on the business between now and 2050 is shown in the following three levels.

  • Positive : Positive impact on business
  • No change : No change or slight impact on business
  • Negative: Negative impact on business
Upstream Oil and Gas Business and LNG Business

Please scroll horizontally to look at table below.

Awareness of Business Environment Under Each Scenario Impact on Businesses Countermeasures
Current Policy Scenario:
Growth in oil demand is expected to gradually slow, with demand peaking in the mid-2030s and then leveling off toward 2050. Demand for natural gas is expected to grow steadily for the power and industrial sectors in emerging Asian countries, centered on China and India.

Transition Scenario:
Oil demand is expected to decline by half through to 2050 amid progress towards a low-carbon society, mainly through electrification of the transportation sector in developed countries, and natural gas demand is expected to remain firm in the medium term for the next 5 to 10 years as a substitute for coal-fired power generation. By 2050, however, demand is expected to decline to about two-thirds, centered on the power generation sector, due to the spread of renewable energies. Meanwhile, new demand for hydrogen feedstock and other applications is expected to grow over the long term.

Current Policy



No change
We will continue to work on improving asset value, including strengthening the competitiveness of existing business assets, reducing GHG emissions, and low carbon/decarbonization initiatives. For new projects, we will carefully select highly competitive projects, taking into account potential future carbon costs, and build a well-balanced portfolio of business assets, including implementing timely asset recycling. While contributing to the low-carbon and decarbonization of the entire value chain, we will continue to work on upstream development of natural gas, which is a transition energy and can be used as a feedstock for next-generation fuels, and to increase our liquefaction capacity. We aim to realize the earliest commercialization of our CCS/CCUS business utilizing our upstream business know how, our geothermal business, and our hydrogen and ammonia business leveraging our gas upstream assets and our existing customer network.
While faced with the dual challenge of needing to expand quantity and improve quality, renewable energy will steadily expand, and fossil fuels will remain indispensable as a primary energy source for the time being. With oil demand peaking and expected to remain flat or decline in both scenarios, there is a risk that the value of upstream assets will decline. Natural gas is an important transition energy source with relatively low environmental impact and a realistic solution to meet growing demand while addressing climate change challenges, and demand is expected to remain strong in the near term under the Transition Scenario. New business opportunities are expected for geothermal power generation, low carbon/decarbonization initiatives such as CCS/CCUS and CO2-EOR* technologies, and next-generation fuel initiatives such as biofuels, hydrogen, and ammonia.
*CO2-EOR: Enhanced Oil Recovery using CO2
Metallurgical Coal Business

Please scroll horizontally to look at table below.

Awareness of Business Environment Under Each Scenario Impact on Businesses Countermeasures
Current Policy Scenario:
In developed countries, demand is expected to gradually decline from the 2030s against a backdrop of declining crude steel production and lower blast furnace ratios due to utilization of ferrous scrap, while demand in India and Southeast Asia is expected to grow from the late 2020s onward due to addition of blast furnaces in the region. Global demand for metallurgical coal is expected to increase moderately from current levels through to 2050.

Transition Scenario:
Demand for metallurgical coal is expected to remain flat over the medium to long term and remain at current levels in 2050, due to further acceleration in the use of ferrous scrap and alternative raw materials in developed countries, as also expected in the Current Policy Scenario.

Current Policy

No change


As demand for metallurgical coal is expected to remain strong over the medium to long term, we will strive to strengthen the competitiveness of our assets while maintaining stable supplies to customers. We will closely monitor changes in the external environment, and strengthen our efforts such as utilizing the methane gas produced and shifting to alternative fuels and raw materials, with a view to realize a low-carbon/decarbonized society together with our business partners.
Under both the current policy and transition scenarios, demand for metallurgical coal is expected to remain flat or increase slightly, and the cost competitiveness of our assets will be maintained, and therefore business profitability is expected to remain strong. Continuous close attention must be paid to the business impact of policies and policy trends of respective countries.
Additionally, we are no longer adding new thermal coal projects to our existing assets.
Thermal Power Generation Business

Please scroll horizontally to look at table below.

Awareness of Business Environment Under Each Scenario Impact on Businesses Countermeasures
Current Policy Scenario:
Fossil fuel-based power generation will gradually decline over the long term. Meanwhile, demand for new power plants is expected to continue in the medium term in some emerging countries where electricity demand will continue to grow and where renewable energy alone is not sufficient to meet supply needs.

Transition Scenario:
Fossil fuel-based power generation is expected to decline at a faster rate in the medium to long term than under the Current Policy Scenario.

Current Policy

No change


Amid the global trend towards low carbon and decarbonization, we will work to transform our portfolio and improve quality in accordance with changes in the environment. Specifically, we intend to reduce our coal-fired thermal power footprint from our power generation capacity over the medium to long term, while increasing the ratio of renewable energy in our power generation portfolio, including hydroelectric power, to over 30% by 2030.
In addition, as a responsible power producer, we will continue to examine ways to improve the efficiency of our existing thermal power assets, including utilizing CCUS, ammonia co-firing, and other low-carbon and decarbonizing technologies.
We will consider new gas-fired power projects, taking into account the need for gas-fired power as a transition energy source and potential future carbon costs, as well as the power supply mix and electricity demand outlook for each region.
The impact of changes in the external environment on our existing business is limited, as most of our power asset portfolio is based on long-term power purchase agreements—in which consideration is paid for the generation capacity rather than for generated volume. However, under the Transition Scenario, the global trend towards low carbon and decarbonization will rapidly accelerate, which may affect the business viability of some assets after power purchase agreements expire, and therefore ongoing verification and monitoring is required.
Iron Ore Business

Please scroll horizontally to look at table below.

Awareness of Business Environment Under Each Scenario Impact on Businesses Countermeasures
Current Policy Scenario:
Although crude steel production in China, the world's largest producer, is expected to decline going forward, this is expected to be offset by increased production in India and Southeast Asia. We predict that global crude steel production will remain steady over the medium to long term.

Transition Scenario:
With higher rates of use of electric furnaces, and an increase in production of direct-reduced iron, which mainly uses high-grade ore, we expect an increase in demand for high-grade ore, and a corresponding increase in premiums/discounts for high-grade iron ore/low-grade iron ore.

Current Policy

No change


No change
For the foreseeable future, we will work to strengthen the competitiveness of our assets while providing stable iron ore supplies to customers, and continue to closely monitor the rate at which electric furnace production methods spread as a means of low-carbon and decarbonization in the steel industry, and the speed of change regarding new steelmaking technologies. In addition, we will strengthen efforts towards realizing a low-carbon society together with our business partners, while closely monitoring changes in the external environment.
Although crude steel production is expected to be affected by a peak-out in China in the mid-2020s, India and Southeast Asia are expected to offset the decline in China. Crude steel production and iron ore demand are expected to remain steady over the medium to long term under both the Current Policy and Transition Scenarios. The transition scenario incorporates an increase in premiums and discounts for high-grade and low-grade ore, but the impact on overall earnings will be limited. The business impact of policies and policy trends in each country will need to be continuously examined.
Offshore Oil and Gas Production Facilities Business

Please scroll horizontally to look at table below.

Awareness of Business Environment Under Each Scenario Impact on Businesses Countermeasures
Current Policy Scenario:
Demand will decline over the medium to long term in line with a slowdown in oil demand growth; however, the timeline of this will differ by region.

Transition Scenario:
Demand for oil infrastructure will decline earlier than under the Current Policy Scenario due to the promotion of electrification in developed countries.

Current Policy

No change


No change
Considering the scenario of declining demand in the medium to long term, we will work to transform our businesses into a field where we can utilize the expertise we have accumulated from our existing business (e.g., floating offshore wind power).
Most of the recent projects related to offshore oil and gas production facilities, such as FPSO facilities and drillships, are based on committed long-term use by customers under long-term contracts. Therefore, the impact of the Current Policy and Transition Scenarios on existing businesses is expected to be limited.
Gas Distribution Business

Please scroll horizontally to look at table below.

Awareness of Business Environment Under Each Scenario Impact on Businesses Countermeasures
Current Policy Scenario:
Demand is expected to increase steadily in line with rising gas demand in emerging countries.

Transition Scenario:
Demand is expected to grow at a slower pace than under the Current Policy Scenario due to the spread of renewable energy.

Current Policy

No change


No change
We will continue to work on improving asset value, including GHG emissions reduction and decarbonization. For new projects, we are working in consideration of potential future carbon costs.
Our gas distribution businesses are granted exclusive long term concession rights in each of the concession areas. Therefore, the impact of the Current Policy and Transition Scenarios on existing businesses is expected to be limited.
LNG Shipping Business

Please scroll horizontally to look at table below.

Awareness of Business Environment Under Each Scenario Impact on Businesses Countermeasures
Current Policy Scenario:
Demand for natural gas is expected to grow steadily over the long term for use in the power and industrial sectors in emerging Asian countries, and therefore, demand for operation of ships for natural gas is expected to increase.

Transition Scenario:
Demand for natural gas is expected to continue in the medium to long term as a substitute for coal-fired thermal power generation, and new demand is expected in the long term for hydrogen feedstock and other applications. Therefore, demand for operation of ships is expected to increase.

Current Policy

No change


No change
With consideration for medium- and long-term supply and demand and price trends, we will strive to maintain and improve the profitability of individual businesses, as well as working to ensure stable and streamlined operations, and at the same time identify new businesses including the establishment of a hydrogen supply chain and next-generation fuel tankers.
In the LNG shipping business, most of the recent projects have secured earnings based on long-term contracts. Therefore, the impact on the Company's earnings under the Transition Scenario will be limited.
Renewable Energy Business

Please scroll horizontally to look at table below.

Awareness of Business Environment Under Each Scenario Impact on Businesses Countermeasures
Current Policy Scenario:
Demand is expected to increase substantially over the medium to long term in response to global low carbon and decarbonization trends and energy security.

Transition Scenario:
Demand is expected to increase substantially at a faster rate than in the Current Policy Scenario.

Current Policy



In line with the global trend towards low carbon and decarbonization, we will work to transform and improve the quality of our asset portfolio in response to the changing environment. Specifically, in order to raise the ratio of renewable energy in our power generation portfolio to over 30% by 2030, we will engage in large-scale renewable energy projects including solar power, onshore wind power, and offshore wind power, as well as local production for local consumption type distributed renewable energy projects, to meet local demand.
In addition, in view of the potential for intensified competition among operators, we will aim to capture added value by establishing a renewable energy business cluster, leveraging our comprehensive strengths to engage in peripheral fields including the production and sale of green hydrogen, ammonia, and methanol using renewable energy, clean energy sales, EV infrastructure, and offshore wind power infrastructure.
While the renewable energy industry is expected to experience significant growth in demand, competition is likely to intensify as the number of operators in the segment grows.
Meanwhile, supply-demand balance adjustment needs are expected to expand in some regions in order to cope with grid instability caused by the rapid increase in the rate of renewable energy sources. In addition, the energy solution business utilizing digital technology is also expected to expand.
The Electric Vehicle (EV) market is also expected to grow with the support of government policy in various countries, and demand for clean power is expected to grow.
Next-Generation Energy Business

Please scroll horizontally to look at table below.

Awareness of Business Environment Under Each Scenario Impact on Businesses Countermeasures
Current Policy Scenario:
Demand for biofuels and other next-generation energy is expected to continue to grow strongly over the medium to long term, mainly as a replacement for liquid fossil fuels.

Transition Scenario:
Demand for biofuels is expected to grow rapidly in the medium term, and while the growth rate will slow over the long term, demand for biofuels for aviation and marine transportation is expected to continue to expand. Under this scenario, hydrogen and fuel ammonia are expected to grow rapidly, replacing natural gas in the medium to long term.

Current Policy



We are working to expand our biofuel business leveraging the technology and expertise of our existing investees. In addition, we are moving forward with initiatives in hydrogen and fuel ammonia, geothermal power generation projects, and other areas, as we view them as realistic solutions for realizing a low-carbon or decarbonized society. While these areas are expected to become next-generation alternative energy sources, further technological innovation is necessary for full-scale expansion. Accordingly, we have formed a specialized in-house team and are accelerating these efforts.
There is a significant expectation that demand for next-generation energy will grow, and promising next-generation energy technologies are in the process of being developed. Along with the development of new government programs, etc. in each country, we expect further accelerated investment in the development of new technologies and lower costs of producing low-carbon and decarbonized energy, stimulating further growth in demand and creating new business opportunities.
Forest Resources Business

Please scroll horizontally to look at table below.

Awareness of Business Environment Under Each Scenario Impact on Businesses Countermeasures
Current Policy Scenario:
Demand for forest resources is expected to grow in line with expansion in paper and housing markets in emerging nations.

Transition Scenario:
Growth in demand is expected for timber, a renewable natural material that absorbs CO2 emissions, and is also a source for generating emission credits.

Current Policy



We will expand our forest resources business by accumulating assets based on profitability/risk to serve as a foundation for the creation of environmental value and industrial solutions to social issues. We will aim to maximize the value of forest resources not only by expanding paper and housing applications and emission credit creation, but also by developing new needs for timber materials.
Under the Current Policy Scenario, an increase in demand is expected for renewable and natural materials that contribute to climate change response, especially timber. Under the Transition Scenario, demand for emissions trading is expected to increase and the price of emission credits is expected to rise, which we expect to boost profitability.

Physical Risk Assessments

We operate a wide range of businesses in various countries and regions, which may be affected by the manifestation of physical risks if climate change causes an increase in extreme weather events. In order to clarify the impact of physical risks on our business, we conducted analyses that refer to the RCP8.5 scenario and others, and for businesses with investable assets above a certain amount, we conducted research and impact analysis based on climate disasters that have occurred in the past five years. The major physical risks facing assets owned by Mitsui include the potential for localized storms, particularly strong tropical hurricanes and cyclones arising in the Atlantic and South Pacific, which could cause negative impacts on operations in our mineral and metal resources projects. Furthermore, in cases of severe damage to production plants, facilities or infrastructure, such as the roads, railways, and ports used for shipments, there is a risk that production or shipments could be suspended for long periods until these facilities are restored. On top of Mitsui's own investments, in cases where Mitsui suppliers suffer significant damage, there is a possibility of the risk of the overall supply chain failing, including failures to receive supplies of raw materials.

We place the highest priority on protecting human lives in the event of a disaster. In addition, we have established crisis management policies for business continuity that also takes into consideration coexistence with local communities. We have also taken measures to mitigate and adapt to risks, such as securing multiple suppliers, enhancing our facilities, and obtaining insurance coverage as necessary. We will continue to assess the adequacy of our risk management measures on a regular basis.

The major physical risks in our assets are as follows.

Physical Risk Assessments

Risk Management

We identify company-wide material risks across organizational boundaries and implement a wide range of initiatives to hedge and control risks. For this purpose, Mitsui has established an integrated risk management system that centrally manages company-wide risks, through the Portfolio Management Committee under the Corporate Management Committee. Under the integrated risk management system, the Corporate Staff Divisions, which act as the secretariat, manage risks from a company-wide perspective. Material risks we assume include those related to the environment, society and governance, such as risks from climate change, compliance, and infectious disease, disasters, terrorism, etc. We position risks regarding climate change (physical and transition) in particular as second in importance only to business investment and country risks and are taking corresponding measures. For details of our risk management structure, please refer to the following page.

Governance: Risk Management

For Mitsui & Co., which operates in countries and regions around the world, the policies of each country and region related to climate change have a significant impact on the profitability and sustainability of each of our businesses. We use the climate-change scenarios published by the IEA and other organizations when we analyze scenarios involving businesses that have significant impacts. In this way, we are gaining an understanding of business impacts both in terms of risk and opportunity. When considering investment projects, M&A, and other business decisions, we take these scenarios into account.

In conducting business, we have put in place a system to ensure that utmost consideration is given to the environment and society in projects at all stages, including at the launch of a new business, during operations, and even at the time of withdrawal from the business. Our Sustainability Committee discusses response policies and measures regarding environmental and social risks (including climate-change risk), then reports to the Corporate Management Committee and the Board of Directors, which then applies them following approval.

Metrics & Targets

GHG Reduction Targets

  • Scope 1 and 2, and Scope 3 Category 15 (Investments) of the Company and its consolidated subsidiaries (including un-incorporated joint ventures):
    Formulating Mitsui's goal to achieve net-zero emissions as our Vision for 2050, and aiming to reduce GHG impact by 2030 to half of what it was in the fiscal year ended March 2020, as the path to achieve the above goal.
  • Scope 1 and 2 of the Company and its consolidated subsidiaries:
    Halving GHG emissions by 2030 compared to the fiscal year ended March 2020.
  • The ratio of renewable energy in our power generation portfolio:
    Raising the ratio of renewable energy to over 30% by 2030, to achieve our goal of halving our GHG impact by 2030.

GHG Reduction Targets

GHG Reduction Targets

GHG impact refers to the amount of our emissions minus the GHG emission reduction contribution amount we achieved through our business activities. We not only focus on reducing our own emissions, but also on contributing to the transition to a low-carbon/ decarbonized society through our business activities. Going forward, we will accelerate our company-wide initiatives by setting specific goals, including our reduction contribution amount.
Net zero emissions in 2050 means to reduce our emissions to effectively zero by subtracting only the amount of absorption and offset from our emissions. The reduction contribution amount is not included in the 2050 target figures, though we will continue to actively contribute to GHG emissions reductions for society as a whole through our business.

We promote emission reduction (Reduction) and reduction contribution (Opportunity & Transition) in a variety of ways, taking advantage of the cross-industrial business structure that only a sogo shosha can offer.

GHG Reduction Targets

Roadmap to Halving GHG Impact by 2030

We aim to halve our GHG impact from 34 million tons in the FY Mar/2020 to 17 million tons in FY Mar/2030.

For the three-year period from FY Mar/2021 to FY Mar/2023, the GHG impact is expected to be approximately 33 million tons.
Although emissions are expected to increase slightly from FY Mar/2024 to FY Mar/2030 due to the start of operations of thermal power generation projects and other factors, we will aim to achieve our goal of halving of the GHG impact in 2030 through a robust combination of emission reduction and reduction contribution projects.

Internal Carbon Pricing System

At Mitsui, we introduced the internal carbon pricing system in April 2020 for the purpose of improving the medium to long-term resilience of businesses emitting large volumes of GHG, and to encourage the development of projects that are effective at reducing our, and society's, GHG emissions. Regarding new business projects, in projects with potential risks or opportunities from GHG regulations, etc., we have added analysis of the potential impact of a 2°C scenario to the project screening factors, as well as the adequacy of countermeasures in the event these risks are realized. We are also using the internal carbon pricing system to assess risks in existing projects. The pricing is based on definitions and prices published by the IEA and other external organizations, taking into account the location and time horizon of the assets, and over the period through 2050 we have applied prices generally in the $10 to $200 range for developed countries and $0 to $160 for the rest of the world.

Environmental ("Green") Business Assessment Working Group

As the transition towards a low-carbon or decarbonized society accelerates, we are working to reduce the GHG emissions from our operations while simultaneously engaging in business that contributes to reducing GHG for society. We aim to realize sustainable growth while helping to solve the challenges faced by society. For these reasons, we decided to establish the Environmental ("Green") Business Assessment Working Group, which launched on April 1, 2021. Its role is to carry out comprehensive evaluations as part of the screening process for new projects with the potential to turn climate change responses, such as the development of renewable energy, into opportunities. The evaluations include qualitative factors, such as the strategic significance of initiatives from ESG perspectives.

Making Electricity Use Carbon Neutral across All Business Locations in Japan (Using Renewable Energy-Derived Credits)

As one of the concrete measures aimed at realizing our 2050 vision, all power supplied to our new Head Office, which we relocated to in May 2020, is carbon neutral. This has been achieved by mainly procuring energy from the Fukushima Natural Gas Power Plant (Shinchi, Soma, Fukushima Prefecture), a facility which has Mitsui as one of its main investors, and by applying renewable energy-derived credits generated by the biomass power generation of our affiliate company Konan Utility Co., Ltd. ("Konan Utility"). We have also applied credits generated by Konan Utility and Mitsui's Forests to the electricity used in all offices and training centers in Japan, enabling us to make all business locations in Japan carbon neutral.

Initiatives in adaptation to climate change — controlled environment agriculture business in the Middle East

  • Nutrition & Agriculture Business Unit
A controlled environment agriculture facility operated by Zero of ItalyA controlled environment agriculture facility operated by Zero of Italy

In March 2022 we became involved in a controlled environment agriculture (CEA) business in the Middle East. Together with retailer Tamimi Markets of Saudi Arabia, and Zero SRL, an Italian CEA business operator, we established a joint venture and will launch a pilot project to verify the production and sales capabilities of facilities for growing crops in a controlled environment, in anticipation of future large-scale production. Although the consumption of fresh produce is on the rise in the Middle East, the harsh local environment is an issue in raising levels of food self-sufficiency.
CEA facilities use less water to grow plants by controlling the volume of water needed (resulting in about a 90% reduction in water use compared to open-field cultivation). They generate 45% less CO2 emissions, and offer stable supplies of produce without being affected by the weather. Due to the close proximity from farm to shelf, food loss during transportation, and CO2 emissions (food mileage) from food transportation can both be reduced.
Due to growth in the world population, it is said that the area of cultivated land per person will decline by around 25%* by the year 2050, compared with 2005. Given this background, the need for low-environmental-impact agricultural production is expanding, and with the growing awareness of environmental and social issues in agricultural production, such as the visualization of food chains, more sustainable agricultural productivity is needed.
By enabling the local production and consumption of fresh vegetables and fruit through the CEA business, we will contribute to improving the local levels of food self-sufficiency, quality, and safety and security.

Mainstream is, as a developer of wind and solar assets, one of the leading companies in the renewable energy sector, in particular in Latin America and Africa. It has a successful track record of having developed 6.5 GW of generation capacity to financial close-ready stage, including offshore wind farms in UK. Currently, Mainstream has a portfolio of approximately 16.6 GW of high-quality energy assets in Latin America, Africa, and Asia-Pacific, which are currently operating, under-construction or in development phases. Mainstream recognizes energy transition as an opportunity to expand its global portfolio and aims to develop 25 GW of energy assets over the next 10 years.
Aker ASA, the owner of Aker Horizons, was founded in 1841 and is an industrial investment company, the second-largest oil & gas major in Norway. Aker ASA established Aker Horizons as its platform dedicated to investing in, incubating, and developing companies within renewable energy and decarbonization technologies. In addition to Mainstream, Aker Horizons owns Aker Carbon Capture (a CO2 capture and storage development company), Aker Clean Hydrogen (a clean hydrogen and ammonia development company), and Aker Offshore Wind (an offshore wind power development company).
We will contribute to the growth of Mainstream and the enhancement of its corporate value by utilizing our know-how in the construction and operation of large-scale power plants around the world and our global customer network. Through this investment, we will promote the development of renewable energy power sources with a sense of scale, further improve the quality of our power generation portfolio, and accelerate the reduction of GHG emissions in society through our operations.

Investment in India's large-scale renewable energy business

  • Infrastructure Projects Business Unit

Through our wholly-owned subsidiary MIT Power India, we have invested in the development of a large-scale renewable energy project promoted by ReNew Power Private Limited, the largest renewable energy company in India. The project will consist of three newly built wind farms in India (900 MW in total) and one solar power plant (400 MW plus a battery storage farm with a capacity of up to 100 MW). The project will provide 400 MW of electricity to Solar Energy Corporation of India Limited ("SECI"), an entity owned by the Indian Ministry of New & Renewable Energy, based on a 25-year power purchase agreement. While it is difficult for conventional renewable energy projects to commit stable electricity supply due to the intermittent nature of winds and solar irradiation, this Project commits electricity supply of 400 MW with high capacity factor on a round-the-clock basis from a portfolio consisting of multiple wind and solar plus battery storage farms. This is the first of its kind in India ("round-the-clock scheme"). The total cost of the project will be around US$1.35billion. The commercial operations are scheduled to start by August 2023. Mitsui will contribute to the project by using its accumulated knowledge of the electric power business in Japan and other countries to ensure steady progress toward completion and the smooth start-up of commercial operations.
India, the third-largest emitter of GHG, declared its commitment to cut its emissions to net-zero by 2070 at the 26th Conference of Parties ("COP26") held in November 2021 and announced that it will raise its non-fossil energy capacity to 500 GW by 2030. This round-the-clock scheme Project, enabling electricity supply with 100% renewables, is in line with the Indian Government's policy and is expected to play an important role in the future to replace coal-fired generation currently dominant in India. Renewable energy is a business field that is likely to continue to expand in India, where continuous growth in population and GDP is expected. Through this project, we will contribute to solving the power shortage in India and encourage decarbonization.

Development of clean hydrogen production technology

  • Energy Solutions Business Unit

We have invested in EKONA Power Inc. of Canada, which has been developing a novel methane pyrolysis process for making clean hydrogen from natural gas.
Hydrogen will play a critical role in industrial decarbonization and has significant potential as a clean energy source, as hydrogen emits no CO2 when burned and can be used in power generation, mobility, and other industries. However, technical and economic challenges lie in clean H2 production such as CCS (Carbon dioxide capture and storage) needed for abating CO2 emitted from production process of hydrogen.
EKONA is developing a methane pyrolysis process, which enables the production of hydrogen and solid carbon from methane. This technology will achieve lower CO2 emissions in the production process, while curbing the production cost to the same level as other conventional hydrogen production technologies, such as a steam methane reforming. With this technology, the majority of carbon is generated in solid form, which eliminates the need for CCS. In addition, existing infrastructures for natural gas and LNG can be maintained, as natural gas is used as feed gas for this production process. Amid the rapid shift toward industrial decarbonization, we will explore a clean hydrogen business opportunity in Japan utilizing EKONA's technology.

* The method of producing hydrogen by of converting fossil fuels into gas through endothermic catalytic reaction and extracting hydrogen from the gas is called the "reforming method". In particular, the method to produce hydrogen by reforming methane is called the steam reforming method and has been widely used in industry. While the production cost is relatively low, the accompanying CO2 emissions are a challenge.

EKONA's methane pyrolysis process This technology can produce clean hydrogen by decomposing methane into hydrogen and solid carbon under high temperatures using a proprietary pyrolysis method that does not require any catalysts. EKONA's methane pyrolysis process

Delivering green hydrogen Delivering green hydrogen

On April 2022, we invested 10 million euros (approximately ¥1.35 billion) in French company Lhyfe SA, which produces green hydrogen in Europe using renewable energy through a production process that emits zero CO2. Lhyfe was established in 2017 by former employees of the French Alternative Energies and Atomic Energy Commission (CEA), to reduce GHG emissions through the production of green hydrogen. Its first commercial plant, to produce renewable green hydrogen using power from wind turbines, was inaugurated in 2021. The company is already active in ten countries in Europe and has over 90 pipeline projects, with production start dates between 2022 and 2028. Lhyfe's target markets are mobility and industry usage.
Under its "Green Deal" policy, the European Union has set a target of achieving net zero emissions by 2050, as well as installation of 40 GW of renewable hydrogen electrolyzers by 2030. Systems are being designed and introduced to encourage the use of hydrogen. Through our participation in Lhyfe, which produces green hydrogen locally for local consumption, we will become an insider in the European hydrogen market and will contribute to the enhancement of Lhyfe's corporate value by developing customers and leveraging synergies with its existing hydrogen-related business. Furthermore, we will establish a hydrogen earnings base in Europe and contribute to the accelerated reduction of GHG emissions via the development of the green hydrogen industry there.

Green hydrogen refueling station business for fuel cell-powered heavy vehicles in New Zealand

  • Energy Solutions Business Unit

Based on a strategic alliance agreement that we concluded with Hiringa Energy Limited ("HE") in June 2020, we invested in Hiringa Refuelling New Zealand Limited (a subsidiary of HE) in September 2021 to develop a network of green hydrogen refueling stations for fuel cell-powered heavy vehicles in New Zealand.
New Zealand is blessed with an abundance of renewable energy sources ("renewables") that include hydropower, geothermal energy, and wind power. The New Zealand government aims to increase the proportion of electricity generated by renewables from the current 85% to 100% by 2030. While the GHG emissions ("emissions") from the country's power generation sector are limited, the emissions from the transportation sector are relatively high and likely to further increase.
In its initial stage, Hiringa Refuelling New Zealand Limited will set up hydrogen refueling stations in New Zealand's four transportation hub cities by the end of 2022, to supply green hydrogen derived from renewable energy to large vehicles that have high emission levels. Although large vehicles only account for around 4% of all road vehicles registered in New Zealand, the emissions of the road transportation sector, to which large vehicles belong, are responsible for about 40% of emissions. The aim is to significantly reduce these emissions. In the future, we aim to expand hydrogen supply bases and accelerate the reduction of emissions in New Zealand's transportation sector.
Through our initiatives with HE to realize a sustainable system of local hydrogen production for local consumption to help promote a hydrogen-based economy in New Zealand, we will take on the challenge of the green hydrogen business, which is one of the solutions to the urgent and complex global issue of responding to climate change.

Rice straw processing at Kulbucharan Briquettes plant (Punjab state) Rice straw processing at Kulbucharan Briquettes plant (Punjab state)

In August 2021 we invested in Punjab Renewable Energy Systems Pvt. Ltd. ("PRESPL"), a biomass supply-chain management company in India.
India is one of the world's leading agricultural powers. One of the major causes of air pollution in India today is the practice of burning straw stubble and other agricultural residues left after crops have been harvested. To help address this problem, the Indian government has introduced policies to promote the effective utilization of non-edible resources such as biomass residue that does not compete with food. The biomass energy market in India is expected to further expand. Since its start in 2011, PRESPL has utilized the strong network that it has built up with local farmers. The company is expanding its operations in a range of businesses, from the collection and supply of agricultural biomass to the manufacture of briquettes from agricultural biomass and the supply of biomass fuels.
Through this investment, we will promote and enhance energy businesses in India that use agricultural biomass. Following this investment, we will use the synergies with our wide range of business assets to expand PRESPL's business and expand the biofuel business in India and around the world. This will help solve air pollution and other societal issues in India, and will also contribute to solving global issues such as global warming.

Joint feasibility study for the creation of a supply chain of CCS clean fuel ammonia in Western Australia

  • Energy Business Unit I

Mitsui & Co., Ltd. and Japan Oil, Gas and Metals National Corporation ("JOGMEC"), looking ahead to the commercialization of clean fuel ammonia production in Western Australia, reached an agreement in 2021 to conduct a joint feasibility study into carbon capture and storage (CCS). Our wholly-owned subsidiary Mitsui E&P Australia Pty. Ltd. ("MEPAU") concluded the agreement with JOGMEC.
In addition, MEPAU has also agreed with Wesfarmers Chemicals, Energy & Fertilisers Limited ("WesCEF") to jointly study the commercial and technical viability of building a low carbon ammonia production plant in Western Australia. The two companies exchanged memorandums of understanding.
MEPAU is developing the Waitsia gas field in Western Australia, in which it has a 50% working interest. MEPAU also holds a 100 percent working interest in depleted gas fields near the Waitsia gas field. By linking these two underground resources (natural gas production and CO2 storage) that are near to one another, we plan to not only be an operator of oil and gas production in Western Australia but also be involved in the production of clean fuel ammonia using our excellent gas assets and to export this fuel to Asia, including Japan.
Specifically, the study will consider the manufacture and export of clean ammonia in which the hydrogen made from the reformation of the natural gas produced by the Waitsia gas field is used to synthesize ammonia, and the CO2 generated in the synthesis is stored in the depleted gas field. In this joint study, we will look into the effectiveness of CCS in depleted gas fields.
MEPAU decided to work with WesCEF, as it has a wealth of knowledge in ammonia manufacturing and sales. MEPAU and WesCEF are planning to collaborate by utilizing the strengths and know-how of both companies, to achieve the supply of clean fuel ammonia to Australia and Asia (including Japan). The two companies will also contribute to the Australian economy through investment and job creation to establish a supply chain for clean fuel ammonia.
We will utilize our extensive knowledge of the upstream natural gas industry, as well as the knowledge gained through our investment in Storegga Limited (UK) in March 2021 to develop our CCS business globally. We aim to provide low-carbon energy and CO2 reduction solutions to the world to help achieve an "environmentally harmonious society."

Electricity Resource Development and Power Management

The Smart Grid and Distributed Electricity Resources

  • Infrastructure Projects Business Unit

Demand for energy has been growing throughout the world, especially in Asia and Africa, along with the steady economic growth of these regions. The power sector has seen a pronounced trend towards Decarbonization, Decentralization, and Digitalization (the "3 D's"), and a rapid shift is underway towards renewable energy, which is more environment-friendly. Mitsui & Co. is responding to the "3 D's" trend not only through the development of utility scale solar power and wind power projects, but also through the global roll-out of distributed power generation projects that provide service closer to the end-user. Globally, approximately one billion people—mostly in Asia and Africa—have limited access to electricity*, and for India also, this is a major problem. At the same time, mobile phone penetration rates tend to be very high even in the inadequately-electrified regions of India and Africa, making electricity necessary for communication purposes. In 2017, we invested in OMC Power Private Limited (OMC), which is specialized in a business model with a combination of solar power and batteries to implement a distributed electricity generation business in which electricity is produced and consumed locally. With mobile carriers' telecom towers being the anchor customers, OMC supplies reliable electricity to local businesses and communities as well. OMC provides stable and affordable electricity mainly through environment-friendly solar power, as well as enhancing the lives and economic prosperity of rural communities. Currently, OMC operates 280 power generation plants, which supply power to 238 telecom towers, 11,000 local businesses, and approximately 100,000 residents in 15,000 households. We will be working with OMC to deliver electricity to other inadequately-electrified regions.
We also help to supply electricity to sub-Saharan Africa through our investment and participation in M-KOPA Holdings Ltd. ("M-KOPA"). M-KOPA runs a business called the Solar Home System ("SHS"), through which solar panels are installed on the roofs of houses or small stores, and solar power generation is used to provide power for lighting, mobile phone chargers, and home appliances (radios and televisions). Up until recently, more than 600 million people living in sub-Saharan Africa have been using kerosene, which is a fossil fuel, for lighting and cooking, because of the delayed development of the power transmission grid. However, thanks to the SHS, there has been a reduction in kerosene use, helping to reduce the environmental load. In Africa, a large increase in demand for electricity is expected as a result of the improved living standards and lifestyle changes that will result from future rapid economic growth. By accelerating efforts to strengthen and expand the services M-KOPA provides, we will support more convenient and comfortable lives for people living in Africa.

EV (Electric Vehicles)

  • Mobility Business Unit I
  • Energy Solutions Business Unit

Among the mobility (transportation) fields that we have defined as our new growth fields, we expect electrification (the shift to electric vehicles) to be particularly promising. In Europe, where the introduction of EVs is gathering momentum, we are building a comprehensive business model that supports the changeover to EVs, including infrastructure, and are expanding it in other regions as well.
We are organically linking several companies in which we have an interest in order to build a new business model that can provide comprehensive solutions. These include EV makers (Lucid Group, CaetanoBus-Fabricação De Carroçarias S.A, Letenda Inc.), battery pack manufacturers (Forsee Power SA), and an energy management company that uses EV batteries (The Mobility House AG). For example, if a city considers switching its fixed-route buses to EV, we would like to help the city speed up its changeover to electric vehicles. In concrete terms, we can offer a comprehensive range of services including EV bus supply, battery leasing, and energy management. Furthermore, in future we are also considering businesses involved in the reuse and re-leasing of used batteries. We will begin these initiatives in Europe and the United States, and then expand them to Asia.

ZEV (Zero Emission Vehicle) Bus Operations in Europe

  • Mobility Business Unit I

In December 2017 we invested in Caetano Bus, S.A. of Portugal. This company has been involved in the development of electric buses since 2010. In 2016 they began the sale of ramp buses used to transport passengers within airports, and in 2017 the company started commercial production and sales of electric transit buses in Europe. We are using our global network to help in the expansion of sales of the company's buses. As an example of Caetano's global expansion, a total of 34 single-deck electric buses were delivered to two London routes in the spring of 2020. The company also completed the development of an FC (fuel cell-powered) transit bus at the end of 2020. Beginning with Germany and Saudi Arabia, we have started selling FC buses that use Toyota fuel cell systems. In our partnership with Caetano Bus, we will continue looking to provide the optimal solutions suitable for operations seeking to achieve a carbon-free society.

Participation in the CCS Business

  • Energy Business Unit I

CCS stands for Carbon Capture and Storage. We have invested in CCS company Storegga Limited ("Storegga") of the UK. Storegga is developing the Acorn CCS project to capture, transport, and store CO2 emitted from the UK and neighboring countries, to reduce CO2 emissions and achieve CO2 net-zero emissions by 2050, a target that has been set by the UK government. The Acorn CCS project will use depleted oil and gas fields where production has ceased as reservoirs for the storage of CO2. In this way, the project will reutilize existing infrastructure and will achieve cost competitiveness. Storegga is also working to commercialize its Direct Air Capture (DAC) technology to extract CO2 directly from the atmosphere, and Mitsui and Storegga have entered into an MOU for the commercialization of this technology. In addition to joint studies with Storegga to commercialize DAC technology, Mitsui will carry out the purchase and sale of carbon credits, and will assess the possibility for investment in the business.
We have also launched a joint feasibility study with Indonesian state-owned oil company Pertamina on CCUS commercialization in Indonesia. This study aims to evaluate the CO2 subsurface storage capacity of the oil and gas fields in Rokan Block, which is operated by Pertamina in Central Sumatra, and to examine the feasibility of establishing a CCUS value chain, including capture and transportation of CO2 emitted from industrial plants, power generation plants, and other facilities. The project aims to create new low-carbon solution business in Indonesia.
Leveraging our knowledge of upstream oil and gas businesses and our extensive business network, we aim to develop a global CCUS business that will include Asia and will provide CO2 reduction solutions to the world, utilizing our comprehensive strengths together with the knowledge gained in the UK and Europe where the development of governmental rules and regulations is advancing.

CCU — Producing Methanol in the U.S. that Effectively Uses CO2

  • Basic Materials Business Unit

Our affiliate, Fairway Methanol LLC, decided in March 2021 to expand its facilities to increase methanol production (approximately 130,000 tons per year) by purchasing and effectively utilizing by-product carbon dioxide (CO2) from surrounding plants (up to approximately 180,000 tons per year) as the source. The decision to expand its facilities was made to maximize the effective capacity of the existing plant, and carbon dioxide sourced from neighboring plants will be used as the raw material for the plant's newly added capacity. This is a CCU (Carbon Capture and Utilization) initiative, which involves separating and effectively utilizing carbon dioxide. Under this concept, CO2 is considered a resource that can be reused as a material or fuel, thus realizing carbon recycling to reduce emissions into the atmosphere.
Demand for methanol is expected to grow steadily in the future as a basic raw material for a variety of industries, including housing and construction materials, high-performance resins for automobiles and electronics, and pharmaceuticals. Recently, methanol has also been attracting attention as a key chemical substance that can be sourced from carbon dioxide. Mitsui has been engaged in the methanol trading business for many years. In addition to the business in North America where this expansion will take place, Mitsui is also involved in a methanol production business in Saudi Arabia.
Through the stable supply of methanol, Mitsui is supporting the development of a wide range of industries and contributing to the realization of a sustainable society. Furthermore, to achieve Net-Zero Emissions by 2050, which is the target set in our Medium-term Management Plan, we will make use of our existing businesses and the know-how we have accumulated through them to promote initiatives to realize a decarbonized society.


Development of a recycled polypropylene manufacturing business

Existing technology (The past), PureCycle technology (The future)

In September 2021, we signed a MOU with U.S. company PureCycle Technologies, Inc. ("PCT") to jointly develop a recycled polypropylene resin production project in Japan.
Further recycling and utilization of plastics are required in Japan to deal with ocean plastic pollution and climate change. Polypropylene ("PP") resin is widely used to produce packaging materials and automobile parts, but the recycled PP has limited application due to the residue of additives, such as colorants which is difficult to remove from the resin.
PCT holds IPs to produce a recycled PP resin called Ultra-Pure Recycled Polypropylene (UPRP) from waste plastic, which has similar qualities to virgin resin. At present, PCT is building a plant that will have an annual production capacity of 50,000 tons UPRP in Ohio, in the U.S., and is aiming to start its operation at the end of 2022. PCT has already sold more than 20 years' worth of recycled PP resin output from its upcoming plant, and is also planning to build a large-scale recycling plant in Augusta, Georgia, in the U.S.
By promoting this joint project, we aim to expand the use of UPRP for consumer goods, food containers, automobile interiors, and other applications. By establishing a supply chain that spans from the securing of supplies of waste plastic, to the manufacture of UPRP, and the supply to customers, we will help to reduce waste plastic and establish a circular economy.
