[Calculation method]

1：Calculated by multiplying the figures shown in the material balance sheet by the relevant values retrieved from the database of emissions unit values built for the calculation of organizations’ greenhouse gas emissions across their supply chains

2：Calculated by multiplying the cost of acquiring tangible fixed assets (shown in the financial statements) by the relevant value retrieved from the database of emissions unit values built for the calculation of organizations’ greenhouse gas emissions across their supply chains

3：For power consumption, calculated by multiplying the amount used by the relevant value retrieved from the database of emissions unit values built for the calculation of organizations’ greenhouse gas emissions across their supply chains. For gases, etc., calculated by multiplying the amount used with the relevant value retrieved from the IDEA LCA database.

4：Extracted from the data notified (for products) by shippers specified under the Act on Rationalizing Energy Use

5：Calculated by totaling CO₂ emissions from the transportation of the company’s waste (extracted from the data notified (for waste) by shippers specified under the Act on Rationalizing Energy Use and CO₂ emissions from the treatment of waste (calculated by multiplying the cost of waste treatment (for fiscal years up to fiscal 2018) or the amount of waste treated (for after fiscal 2019) by the relevant value retrieved from the IDEA LCA database)

6：Calculated by multiplying the number of employees by the relevant value retrieved from the database of emissions unit values built for the calculation of organizations’ greenhouse gas emissions across their supply chains

7：Calculated by multiplying the result of multiplying the number of employees by the number of their working days by the relevant value retrieved from the database of emissions unit values built for the calculation of organizations’ greenhouse gas emissions across their supply chains

11：Calculated by multiplying the amount of CO₂ emissions per one ton of products calculated by using the Japan Auto Parts Industries Association’s LCA tool by the weight of shipped products

12：Calculated by multiplying the weight of shipped products by the relevant value retrieved from the IDEA LCA database

15：Calculated by multiplying the amount of CO₂ emitted by the five companies that are ranked in the top five in terms of the monetary value of the stocks owned by Niterra by the stockholding ratio
