* Notes:
* Emissions from purchased electricity in Japan are calculated using the market-based method.
* The calculation scope is the domestic Mizuno Group and overseas Mizuno Group.
* Scope 1: Greenhouse gas (GHG) emissions from a companyʼs direct operations, such as the in-house use of fuel.
* Scope 2: A companyʼs indirect GHG emissions from purchased electricity, heat, and steam.
* Scope 3: A companyʼs indirect GHG emissions coming from product manufacturing, transportation, employeesʼ business travel and commuting within the supply chain.
* For Scope 1 and 2, emissions are from energy sources.
For Scope 3, non-energy source greenhouse gases are partly included according to the guidelines from the Ministry of the Environment.
* The data marked with ☑ has been assured by a third party in Japanese version of report.
* Scope 1 and 2:
Direct and indirect GHG emissions from corporate activities as defined by the GHG Protocol.
* Scope 3 / Category 1:
The following three methods are used to calculate emission factors according to the characteristics of product categories.
* LCA of the representative model of the product sold by Mizuno in the relevant fiscal year was carried out and the emission factor of the product was calculated. GHG emissions were calculated by multiplying the sales volume with the emission factor. - ①
* In the manufacturing department, GHG emissions were calculated by multiplying the amount of substances used in manufacturing with the emission factor. - ②
* GHG emissions were calculated by multiplying the cost of products sold by Mizuno in the relevant fiscal year with the emission factor specified by the Ministry of the Environment. - ③
Total GHG emissions = ① + ② + ③
* For LCA calculation, the emission factor of LCI database IDEA version3.4 and Database on Emissions Unit Values for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain.
* Scope3 / Category 12
The following three methods are used for calculation according to the characteristics of product categories.
* LCA of the representative model of the product sold by Mizuno in the relevant fiscal year was carried out and the emission factor of the product for disposal specified by the Ministry of the Environment was calculated. GHG emissions were calculated by multiplying the sales volume with the emission factor. - ①
* In the manufacturing department, GHG emissions were calculated by multiplying the amount of substances used in manufacturing with the emission factor for disposal. - ②
* GHG emissions estimated from sales amount based on the GHG emissions calculated from ①. - ③
Total GHG emissions = ① + ② + ③
* For LCA calculation, the emission factor of LCI database IDEA version 3.4 and Database on Emissions Unit Values for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain.
LCA calculations use emission factors from the LCI database IDEA version 3.4 and the emission intensity database for calculating GHG emissions across the supply chain (ver. 3.4).
* Past GHG emission figures have been retrospectively revised due to updates in calculation methods based on the GHG Protocol.
