*1 [Standards/Guidelines for Scope1+2 calculation]
Consolidation : GHG Protocol Control Approach
Measurement : with reference to GHG Protocol "Emission-Factors-from-Cross-Sector-Tools (March2017)," International Energy Agency (IEA) Emissions Factors 2022, IPCC 2006 Guidelines for National Greenhouse Gas Inventories, Act on Rationalizing Energy Use and others
*2 Major consolidated subsidiaries and Un-incorporated JV
*3 Figure for FY Mar/2022 was revised
*4 · Mitsui and consolidated subsidiaries (including Un-incorporated JVs) are calculated according to the control standards (as with Scope 1 and Scope 2)
· Where the same emission source is clearly double-counted among the companies included in the scope of the data, only one is included in the calculation
· In cases where the final product into which an intermediary product is processed cannot be determined, it is excluded from the calculation
· Approx. 60% of total Scope 3 emissions (excluding Category 15 ) are derived from the trading of third-party products and approx. 40% from the production/manufacturing/processing of products at Mitsui
· Trading of third-party products is where Mitsui buys products produced/manufactured/processed by third parties to sell to processors, end users, etc. It does not include transactions with "traders" where the processor or end users cannot be determined
· Category 1 and 11 energy-related emissions are calculated in line with the International Petroleum Industry Environmental Conservation Association (IPIECA) guidelines
· For ferrous raw materials (iron ore and metallurgical coal), Category 10 emissions from production of crude steel are calculated proportionally by weight
*5 Referring to the supply chain emissions calculation database of the Ministry of the Environment
*6 Estimated values of emissions from mineral & metal resources, energy and thermal power generation businesses not included in Scope 1+2 and other affiliated company businesses using LCA databases (IDEA, Ecoinvent), input-output models, etc.
*7 FY 22/Mar : The breakdown of reduction contribution amount and absorption amount was not disclosed, and the total is calculated in units of 1 million t-CO2e.
*8 In some cases, data was obtained directly from project sites, while in other cases, data was only attainable via the head office (parent company/SPC) of the company or companies involved in the project.
*9 Water discharge volume is assumed to be equal to water withdrawal in case of no discharge data
*10 Infectious waste discharged from in-house clinic
