  • CO2 emission factors for fuels and steam
    CO2 emission factors stipulated by the Act on Promotion of Global Warming Countermeasures are used.
  • CO2 emission factors for electricity
    Emission factors for each electric power provider released by the Ministry of the Environment are used for Marubeni Corporation. Until FYE 3/2019, fundamental emission factors (actual emission factors) are used, from FYE 3/2020, adjusted emission factors are used.
    Alternative emission factor stipulated by 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 ton CO2.
    Country-specific emission factors (CO2 emissions per kWh from electricity generation) published by International Energy Agency are used for the international consolidated subsidiaries. Electricity derived from renewable energy is excluded from calculation of Scope2 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 are used.
  • Non-energy related GHG emission before FYE 3/2020 is not included in GHG emissions.
    For FYE 3/2021, non-energy related GHG emission is included in GHG emissions, but the GHG emissions other than non-energy related GHG emission are disclosed in the sub total of Scope 1 and grand total values.

Water Withdrawal from Water-Stressed Regions

By referring to Aqueduct tool 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 Data Survey,” we survey the amount of water withdrawal from the relevant areas.
19 operation sites that have been identified by the “Sustainability Data Survey” with aggregated data as of the end of March 2021, operate in the watershed areas of Gulf Coast, Mississippi - Missouri, RÃo Grande - Bravo, RÃo Lerma, Saskatchewan - Nelson, Columbia and Northwestern United States with relatively high water stress. There is a total water withdrawal of 68 thousand ㎥ in these regions, and we are aware that this is equivalent to 0.1% of 81,086 thousand ㎥ (excluding the portion used for hydroelectric power from the water withdrawal for the whole Marubeni Group). (Furthermore, we have confirmed that no operation sites face comprehensively high water risk, such as the amount of physical water resources, pollution by waste water, regulations, or assessment of nearby regions.)

Activities for Grasping and Managing the Supply Chain

In recent years, companies are required to further disclose information related to climate change and resource issues, toward creating a sustainable society. In calculating greenhouse gas (GHG) emissions that have significant effects on climate change, in addition to Scope 1 (direct emissions) and Scope 2 (energy-originated indirect emission), more and more companies are calculating and reporting GHG emissions for the overall corporate activities (Scope 3) such as resource procurement, production, logistics, sales, and disposal, as well as capital goods, business travel, and commuting. 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 Carbon Disclosure Project (CDP) climate change questionnaire.
