〈Scope 1 & 2 Greenhouse Gas Emissions〉

• CO₂ emission factors for fuels and steam
  CO₂ emission factors stipulated by the Act on Promotion of Global Warming Countermeasures (version before April 2024 enforcement) are used.
• CO₂ emission factors for electricity
  Emission factors (adjusted emission factors) for each electric power provider released by the Ministry of the Environment are used for Marubeni Corporation.
  Alternative emission factor stipulated by the Act on Promotion of Global Warming Countermeasures was replaced by Emission factors (adjusted emission factors) for each electric power provider for the domestic consolidated subsidiaries from FYE 3/2021. The impact on emissions due to the change in emission factors is a decrease of 7,627 metric tons of CO₂.
  Country-specific emission factors (CO₂ emissions per kWh from electricity generation) published by the International Energy Agency are used for the overseas consolidated subsidiaries. A zero emission factor is applied to purchased electricity derived from renewable energy in calculating Scope 2 greenhouse gas emissions since FYE 3/2021.
• Emission factors of non-energy-related GHG
  Emission factors stipulated by the Act on Promotion of Global Warming Countermeasures (version before April 2024 enforcement) are used.
• Non-energy-related GHG emissions are not included in GHG emissions before FYE 3/2020.
  From FYE 3/2021, non-energy-related GHG emissions are included in GHG emissions, however, Scope 1 emissions excluding non-energy-related GHG emissions and grand total emissions excluding non-energy-related GHG emissions are also presented separately.
• Since FYE 3/2022 Marubeni Corporation’s principal offices have achieved zero Scope 2 by purchasing 100% renewable energy for electricity at domestic offices of Marubeni Corporation and procuring J-credits derived from renewable energy heat for steam and cold water purchased as energy at the Tokyo Head Office.

〈Scope 1 Greenhouse Gas Emissions (Components of non-energy-related GHG emissions^*1)〉

• Non-energy-related GHG emissions cover carbon dioxide from the use of dry ice, carbon dioxide, methane, and dinitrogen monoxide from waste incineration or use in the manufacture of products and the use of waste fuels, methane and dinitrogen monoxide from the use of fuel in facilities and machinery used for fuel combustion, livestock waste management, methane from livestock feeding (fermentation in the digestive tract of livestock), hydrofluorocarbons in the recovery and encapsulation of HFCs in the maintenance of commercial refrigeration and air-conditioning equipment, and sulfur hexafluoride in the use of electrical machinery and equipment such as transformers. There are no emissions of perfluorocarbons and nitrogen trifluoride. For sulfur hexafluoride, there are no companies obliged to report based on the Act on Promotion of Global Warming Countermeasures.

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

〈Scope 3 Greenhouse Gas Emissions〉

Marubeni is voluntarily disclosing a part of the data by categorizing its supply chain activities and calculating the GHG emissions in each category in line with the GHG Protocol guidelines. The Scope 3 data is also submitted to the climate change questionnaire of CDP.

Energy and Electricity Consumption

＜Click here to view Tokyo Head Office’s targets to be achieved by FYE 3/2026＞

• 3.6 GJ/MWh is used for heat value per unit for electricity.
• For fuels, the heat values stipulated by the Act on Promotion of Global Warming Countermeasures (version before April 2024 enforcement) are used.
• Biomass energy is not included.
• From FYE 3/2022, Marubeni Corporation’s principal offices have been purchasing 100% renewable energy for electricity at domestic offices of Marubeni Corporation and procuring J-credits derived from renewable energy heat for steam and cold water purchased as energy at the Tokyo Head Office.

Environmental Impact of Transport

• This table shows the impacts associated with the domestic outsourced shipment (upstream transportation) of goods consigned by Marubeni Corporation.

• FSC^® (Forest Stewardship Council^®) (FSC^® C016260): An NPO established to promote responsible forestry around the world and operates systems of international forest certification.
• PEFC (The Programme for the Endorsement of Forest Certification) (PEFC/31-32-80): An international forest certification system, which endorses mutual recognition of forest certification systems of various countries.

Water Withdrawal

〈Water Withdrawal by Source〉

• The river water withdrawn by Mibugawa Power Company for hydroelectric power generation business is included in the figure.
• Mibugawa Power Company’s business is small and medium-sized hydroelectric power project, mainly using flow-in water (self-flowing water). Click here to view detail of the company.
• From FYE 3/2021, raw water withdrawn by companies engaged in water supply and sewerage services, as well as industrial water supply and wastewater treatment as part of their business, is included in the figure of water withdrawn.

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

Water Withdrawal from Water-Stressed Regions

By referring to Aqueduct tools and databases developed by WRI (World Resources Institute), the Marubeni Group identifies regions of which water stress level is “high” or more (“relevant areas”), and through internal reviews such as Sustainability Survey, we survey the amount of water withdrawal from the relevant areas.
Forty operation sites that have been identified by the Sustainability Survey with aggregated data as of the end of March 2024, operate in the watershed areas of Gulf Coast, Mississippi-Missouri, Rio Grande-Bravo, Saskatchewan-Nelson, Kansas, California, Texas, Minnesota, North Carolina, North Dakota, lowa in North America, Maipo in South America with relatively high water stress. There is a total water withdrawal of 94 thousand ㎥ in these regions, and we are aware that this is equivalent to 0.1% of 81,825 thousand ㎥, the amount of water withdrawal for the whole Marubeni Group excluding the portion used for hydroelectric power. (Furthermore, we have confirmed that no operation sites face comprehensively high water risk, such as the amount of physical water resources, pollution by wastewater, regulations, or assessment of nearby regions.)

Water Discharge

〈Water Discharge by Destination〉

• The quality of discharged water is appropriately managed based on the laws and regulations of each country and region.
• The river water used by Mibugawa Power Company for hydroelectric power generation business is included in the figures.
• Mibugawa Power Company’s business is small and medium-sized hydroelectric power project, mainly using flow-in water (self-flowing water). Click here to view detail of the company.
• From FYE 3/2021, the amount of water discharge includes wastewater from sewage treatment projects.

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

• The portion used for hydroelectric power are excluded from water withdrawal.

Number of Legal or Regulatory Violations Related to Water Withdrawal and Water Discharge

In FYE 4/2023, an incident related to wastewater treatment occurred at a domestic site; however, appropriate corrective action has been completed. Since the violation in FYE 3/2018, there has been one violation related to water withdrawal and discharge from FYE 3/2019 to FYE 3/2023.

Costs for water management in FYE 3/2024 are as follows:
・Costs associated with water-related risks: 3,686.4 million yen.
(These include maintenance and repair of water withdrawal and drainage systems and recycling treatment facilities, installation of water-saving equipment, purchase of water discharge treatment chemicals, emergency response training for scenarios assuming the outflow of hazardous substances, and implementation of cleanup activities in the areas surrounding water sources.)
・Investments in R&D to mitigate water-related risks: 3.6 million yen.
