*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 Figures for previous years were revised
*3 ・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
*4 Referring to the supply chain emissions calculation database of the Ministry of the Environment
*5 [Scope3 Investment] 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.

Initiatives toward Environmentally-friendly Logistics

Improvement of Land Transport Efficiency We will use more energy efficient transportation methods.
· Using consolidated cargo
· Using larger transport vehicles to increase loading rates
· Reviewing transport routes and methods
Improvement of Sea Transport Efficiency We will continue to provide the following guidance for vessels chartered and/or operated by our affiliated companies.
· Increasing ship loading rates
· Economic cruise speed operation
