  • 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 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 are used.
  • Non-energy-related GHG emissions before FYE 3/2020 are not included in GHG emissions.
    From FYE 3/2021, non-energy-related GHG emissions are included in GHG emissions, but Scope 1 emissions excluding non-energy-related GHG emissions and grand total emissions excluding non-energy-related GHG emissions are also presented separately.
  • From 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.

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 Data Survey,” we survey the amount of water withdrawal from the relevant areas.
40 operation sites that have been identified by the “Sustainability Data Survey” with aggregated data as of the end of March 2023, 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 97 thousand ㎥ in these regions, and we are aware that this is equivalent to 0.1% of 82,645 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.)
