Note 1. Beginning in fiscal 2020, greenhouse gas emissions (under Scope 1 and Scope 2) and energy usage have been calculated according to the GHG protocol on a consolidated basis. 
Note 2.

・Regarding Scope 3
Categories 2, 3, 6, and 7 are for all consolidated companies.
Category 4 is for domestic consolidated companies.
Categories 1, 5, 11, and 12 are for companies with sales revenue of at least 1 billion yen and whose main business is the manufacturing of products.
・Other categories for which calculated values are not listed are as follows
Category 8, Leased Assets (upstream), is calculated under Scope 1 and Scope 2.
Category 9, Transportation and Delivery (downstream), is excluded from the calculation because the Group’s products are mainly raw materials, materials, and components for final consumer goods. It is difficult to make rational calculations because these encompass a variety of applications, and their transportation and delivery methods are diverse and complex.
Category 10 is excluded from the calculation because it is difficult to grasp the actual situation due to the wide range of products covered.
Category 13 is excluded from the calculation due to the small amount of leased assets involved.
Categories 14, Franchises and 15, Investments, do not encompass such activities.
Note 3. As of fiscal 2022, values for environmentally hazardous substances, waste, and water resources were expanded to include companies eligible for calculation. The targets are the same as the targeted companies of Scope 3. Prior to fiscal 2020, targeted companies were those that were judged to have a high environmental impact under our standards.。
Note 4. Data for FY2023, marked with a 〇, is guaranteed by a third-party organization. Click here to view the third-party report.
Note 5. Water consumption intensity: Freshwater consumption per unit of sales
Note 6. Containers and packaging are subject to recycling obligations under the Containers and Packaging Recycling Law. 
Note 7. Significantly decreased due to the deconsolidation of Air Water & Energia Power Yamaguchi, Ltd. as of January 18, 2023.
