Environmental Data

〈Scope 1 & 2 Greenhouse Gas Emissions〉

• The figures cover Marubeni Corporation and consolidated subsidiaries.
• Until FYE 3/2025, consolidated subsidiaries do not cover the subsidiaries that are designated to be liquidated or sold.
• CO₂ emission factors for electricity (market-based emissions)
  For domestic, until FYE 3/2024, the adjusted emission factors are used. From FYE 3/2025, the basic emission factors (revised in March 2025 and adjusted for non-fossil power sources) are used. For overseas, country-specific emission factors (CO₂ emissions per kWh from electricity generation) published by the International Energy Agency (IEA) are used. 2023 emission factors listed in the IEA Emissions Factors 2025 are used. A zero-emission factor is applied to purchased electricity derived from renewable energy.
• CO₂ emission factors for electricity (Location-based emissions)
  Country-specific emission factors (CO₂ emissions per kWh from electricity generation) published by the IEA are used.
• Emission factors other than electricity
  Until FYE 3/2024, emission factors stipulated by the Act on Promotion of Global Warming Countermeasures (version before April 2024 enforcement) are used. From FYE 3/2025, emission factors stipulated by the Act on Promotion of Global Warming Countermeasures (version after April 2024 enforcement) are used.
• Global warming potential (GWP) values used to calculate GHG emissions
  Until FYE 3/2024, GWP100 in the Intergovernmental Panel on Climate Change (IPCC), Fourth Assessment Report (AR4) are used. From FYE 3/2025, GWP100 in the IPCC Sixth Assessment Report (AR6) are used.
• GHG emissions quantification is subject to uncertainty when measuring activity data, determining emission factors, and considering scientific uncertainty inherent in the Global Warming Potentials.

〈Scope 1 Emissions Breakdown〉

• CO₂ emissions from the use of waste fuels are included in GHG emissions other than energy-derived CO₂.
• GHG emissions other than energy-derived CO₂ cover the production of limestone, CO₂ from the use of dry ice, CO₂ from waste incineration or use of waste fuels，CH₄ and N₂O, the use of fuel in facilities and machinery used for fuel combustion, CH₄ and N₂O from livestock waste management, CH₄ from livestock feeding (fermentation in the digestive tract of livestock), HFCs in the use, maintenance and disposal of commercial refrigeration and air-conditioning equipment etc., and SF₆ in the use, inspection and disposal of electrical machinery and equipment such as transformers. There are no emissions of PFCs and NF₃. For SF₆, 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 1 emissions cover energy-derived CO₂.

〈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 breakdowns of Category 15 and the total value for Category 15 may not match due to rounding.
• The total of each category and the overall total may not match due to rounding.
• The calculation categories: Until FYE 3/2023, the calculation included only Categories 2 to 9 and 15. Starting from FYE 3/2024, Categories 1 and 10 to 13 have been included in the calculation.

Applicable to Categories 1 to 14:

• The boundary of calculation: The calculation includes both Marubeni Corporation and consolidated subsidiaries. For Categories 3 and 4, the boundary has been expanded starting from FYE 3/2024.
• Double counting between companies included in the calculation is excluded when clearly identified.
• In trading, transactions with purchases from or sales to collectors, import/export agents, wholesalers, or intermediaries (i.e., transactions with traders) are excluded when clearly identified.
• Emissions factors: Primarily using the Inventory Database for Environmental Analysis (IDEA) from the National Institute of Advanced Industrial Science and Technology (AIST). Additionally, values from the IEA’s country-specific CO₂ emission factors (CO₂ emissions per kWh from electricity generation), the Ministry of the Environment's emission intensity database, and LCA literature for various industries are also used.
• References: Corporate Value Chain (Scope 3) Accounting and Reporting Standard (GHG Protocol), Technical Guidance for Calculating Scope 3 Emissions (GHG Protocol), Estimating Petroleum Industry Value Chain (Scope 3) Greenhouse Gas Emissions (International Petroleum Industry Environmental Conservation Association, IPIECA), The Product Carbon Footprint Guideline for the Chemical Industry (Together for Sustainability), etc.

Category 1: Includes fertilizers, grains, chemicals, and other products.
Category 4: Until FYE 3/2023, the calculation covered only domestic contracted transportation as a consignor for Marubeni Corporation within Japan. Starting from FYE 3/2024, the calculation includes international maritime transportation, both departing from and arriving in Japan, for Marubeni Corporation as well as its consolidated subsidiaries basis within Japan. Category 10: Sales of intermediate products and raw materials are excluded when the processing stages up to the final product cannot be traced. Category 11: Includes fossil fuels and other products.

Category 15:

• Category 15 covers Scope 1 and Scope 2 emissions for associate investees of the Marubeni Group accounted for using the equity method, (hereinafter, “associate investees”), which are not included in the Scope 1 and Scope 2 emissions of Marubeni Corporation and its consolidated subsidiaries. The emissions are calculated by multiplying by our equity share. Emissions from businesses designated to be liquidated or sold, renewable energy businesses, and businesses which consist of office operations only are not included.
• Generally, emissions are calculated using the same methods as Scope 1 and Scope 2 for Marubeni Corporation and its consolidated subsidiaries. However, in some cases, emissions reported by associate investees and estimated emissions are included.
• For overseas power generation projects, emission factors from the 2006 IPCC Guidelines for National Greenhouse Gas Inventories are used, including CO₂, CH₄, and N₂O. All emissions from coal are calculated assuming weight on an air-dried basis.

〈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 details 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 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 details 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.
