Long-Term Strategy on Climate Change

In accordance with the spirit grounded in “Fairness, Innovation and Harmony,” the Marubeni Group is proudly committed to social and economic development and safeguarding the global environment by conducting fair and upright corporate activities as our Management Philosophy. The Marubeni Group’s long-term strategy is to put our Management Philosophy into practice and to create value and grow by anticipating the challenges of customers and society and providing solutions.

The challenges faced by customers and society are diverse and constantly evolving. To stay ahead of these changes, the Marubeni Group continues to evolve, using four key aspects of diversity—1. human capital, 2. regions, 3. sectors, and 4. business models—as an important differentiator. This is major strength and source of value creation for the Marubeni Group. To further enhance this strength, we have identified the “Fundamental Materiality (1. Human Capital with High Social Value, 2. Robust Management Foundation, 3. Governance for Coexistence with Society)” and are committed to its continuous strengthening.

Climate change is a key factor that impacts the growth of the Marubeni Group and, as such, has been identified as one of the issues under “Environmental & Social Materiality.” To anticipate the societal issues posed by climate change and provide solutions, we have formulated “The Marubeni Long-Term Vision on Climate Change.” In alignment with the Paris Agreement, the Marubeni Group aims to reduce GHG emissions and views the transition to a low-carbon and decarbonized society, both within and outside the Group, as a growth opportunity.

Marubeni categorizes time horizons for its climate change initiatives into short-term (up to 3 years), medium-term (3 to 10 years), and long-term (10 to 30 years). Regarding the financial implications in the long term, the high degree of uncertainty in measurement renders quantitative information less useful. Therefore, qualitative information is provided in the sections “Long-Term Strategy on Climate Change” and “Marubeni Group’s Initiatives for a Low-Carbon and Decarbonized Society.”

For details on “Fundamental Materiality” and “Environmental & Social Materiality,” please refer to the Materiality for Marubeni Group.

The following is based on the information available as of December 2024.

Marubeni Group’s Initiatives Leading the Transition to a Low-Carbon and Decarbonized Society

Leveraging the strengths of the Marubeni Group, we present three examples of how the transition to a low-carbon and decarbonized society is being seized as an opportunity for growth.

Contribute to Low-Carbon/Decarbonization Through Our Businesses

We view GHG emissions across the value chain as opportunities to contribute to their reduction and have calculated all relevant Scope 3 categories. A distinctive characteristic of the Marubeni Group is that its Scope 3 emissions (89 million t-CO₂e) are more than 70 times greater than its Scope 1 and Scope 2 emissions (1.2 million t-CO₂e).

Scope 1, Scope 2, and the Main Categories of Scope 3 for Our Group (for details, please refer to the “Data” section)

The total of each category and the overall total may not match due to rounding.

Category 1: Includes fertilizers, grains, chemicals, and other products.

Category 11: Includes fossil fuels and other products.

Category 15: Includes power generation projects and other projects.

The entities responsible for Scope 3 emissions span a wide variety of sectors. Providing low-carbon and decarbonization solutions to these entities not only significantly contributes to climate change mitigation but also represents a transition opportunity to a low-carbon and decarbonized society, and a driver of growth for the Marubeni Group.
In the energy supply sector, solutions include the development of energy systems that serve as the foundation for a decarbonized society.
On the energy demand sector, efforts to reduce and mitigate GHG emissions over a broad range of industries are crucial. In the land use sector, initiatives such as sustainable agri-inputs businesses and forest management are also key solutions being promoted.
Furthermore, to quantitatively evaluate the effectiveness of these solutions, we calculate both avoided emissions and volume of carbon stocks. These also serve as indicators of how the Marubeni Group is capitalizing on business opportunities.

Specific Examples of Solutions

Avoided Emissions

Avoided emissions refer to a metric that quantifies how the company’s products and services contribute to the overall emission reduction of society.
In the calculation, actual data and publicly available information are used whenever possible. However, when such data is difficult to obtain, reasonable assumptions or scenarios are applied.
As a reference, we primarily use the “Guidance on Avoided Emissions” from the World Business Council for Sustainable Development (WBCSD). However, as international discussions on calculation rules continue, we will regularly review and update our calculation and disclosure methods in accordance with these developments.

Volume of Carbon Stocks

Financial Implications [Current] [Short Term]

Based on the financial results for the fiscal year ended March 31, 2024, an assessment was conducted on the financial implications (impact on financial position, financial performance, and cash flows) of climate-related risks (cash flows, its access to finance or cost of capital that could reasonably be expected to affect the Marubeni Group) in the current period (1. total assets: ¥8,923.6 billion, 2. net profit: 471.4 billion, 3. core operating cash flow^*1: ¥ 548.0 billion) and the short term (up to 3 years). This assessment, based on climate-related “transition risks” and “physical risks,”^*2 concluded that the direct impact on the Marubeni Group within the current and short-term time horizon is less than 1% in each of the categories 1.–3., indicating that the impact is limited.

1  Core operating cash flow: Operating cash flow excluding net increase/decrease in working capital and others

2  Climate-related "transition risks" related to the risks arise from efforts to transition to a lower-carbon economy, including policy, legal, technological, market, and reputational risks. "Physical risks" refer to the risks resulting from climate change that can be event-driven (acute physical risk) or from longer-term shifts in climatic patterns (chronic physical risk).
In assessing “transition risks,” we conducted calculations based on the trends in policies and laws related to carbon pricing in major countries where it has already been implemented. The calculations considered businesses that fall under carbon pricing systems currently in place or expected to be introduced within the next three years (short term) in the countries where the business operates, and where the risk of changes to these systems has not been hedged. As a result, the current financial implications are less than 1%, and even if the carbon pricing rate used for the calculation doubles within the short-term time horizon, the impact is still expected to be less than 1%.
As for the financial implications of “physical risks,” the impact in the current and short-term periods is limited. However, the Marubeni Group has implemented various risk mitigation measures in response to these risks. These measures include assessing potential impacts on business base facilities, logistics, and supply chains at each business site, developing Business Continuity Plans (BCP), disaster prevention strategies, subscribing to various insurance policies, and conducting disaster awareness activities for relevant stakeholders (including employees and local communities), such as initiatives for wildfire prevention. For more details, please refer to the “Policies and initiatives” section in the “Scenario Analysis.”

ACT FOR SKY

Marubeni is a member of “ACT FOR SKY”, an organization dedicated to the commercialization, dissemination, and expansion of domestically produced Sustainable Aviation Fuel (SAF). With the urgent need to reduce CO₂ emissions globally in order to tackle global warming, the aviation industry must accelerate the technological development, production, distribution, and use of SAF. Also, in response to the growing global demand for SAF, a stable supply of domestically produced SAF is essential in Japan. Marubeni has identified “contribution to climate change countermeasures” as one of four categories of our Environmental and Social Materiality, and through “ACT FOR SKY” we will accelerate the commercialization, dissemination, and expansion of domestically produced SAF. At the same time, companies, local governments and others are acting together in cooperation and collaboration to promote the importance of SAF, carbon neutrality, and resource recycling, and to bring about new behaviors through changing the thinking of citizens and companies.
