To help create a decarbonized world, the Mizuno Group will put effort into reducing energy consumption and energy-derived CO2 emissions. In addition, since it believes that reducing GHG emissions effectively requires doing so in collaboration with its entire value chain, Mizuno will put effort into reducing GHG emissions generated when developing products.
Mizuno currently makes various efforts with the aim of achieving its long-term environmental targets. Key examples include solar power generation at domestic factories and the installation of LED equipment at its offices in Japan and overseas. To reduce its energy consumption, Mizuno currently puts effort into strategically installing LED equipment at offices that have a higher risk of imposing environmental burden, such as its headquarters’ buildings and factories. In addition, Mizuno currently puts effort into switching its company cars from gasoline cars to hybrid and other fuel-efficient cars. Furthermore, electric cars have also been introduced and been proving to be safe and environment friendly. Mizuno’s company cars are equipped with Telematics, which allows visualizing how cars are being driven. This has proven to be useful in not only helping drivers pay more attention to driving safely but also improving fuel economy and reducing CO2 emissions.
Mizuno’s total domestic energy consumption in FY 2022 was 144,596 GJ. The intensity of energy consumption＊ was 110.0, a decrease of 13 points year on year.

＊ The breakdown of energy consumption includes non-renewable fuel sources, electricity, heating, cooling, and steam. At this point, fuel sources from renewable energy, such as biofuels, have not been identified.
＊ Energy consumption does not include external energy consumption within the organization.
＊ Intensity of energy consumption: Domestic energy consumption (GJ) / Total domestic sales revenue (hundred million yen)

Energy-derived CO2 emissions
In FY 2022, the Mizuno Group set a goal for its total energy-derived CO2 emissions of 14,111 t-CO2 (a 2.9% reduction compared to the previous fiscal year), but the actual result was 14,326 t-CO2. The increase in electricity and gasoline consumption, influenced by the relaxation of restrictions and the resumption of activities following COVID-19 both in Japan and overseas, affected the results for the fiscal year. Going forward, Mizuno aims to reduce its CO2 emissions through the introduction of energy-saving equipment and the promotion of efficient operations. Additionally, the occurrence of CO2 emissions from biological sources, such as the combustion of biomass, has not been identified.

Other indirect greenhouse gas emissions
Mizuno recognizes that to achieve a decarbonized society, it is essential not only to reduce greenhouse gas emissions generated by the company itself but also to engage in initiatives across the entire value chain. Therefore, Mizuno calculates emissions across the entire value chain based on the Scope 3 standards of the GHG protocol.
In FY 2022, Mizuno’s Scope 3 CO2 emissions accounted for 96.67% of its total CO2 emissions. To reduce the amount of Scope 3 CO2 emissions, Mizuno is making efforts such as collaborating with Sumitomo Warehouse, which operates Mizuno’s main warehouses, to promote the installation of LED lighting, and partially advancing a modal shift in transportation between its major warehouses in Western and Eastern Japan.
Among Scope 3, Category 1 "Purchased products and services" and Category 12 "End-of-life treatment of sold products," which together account for about 80%, were recalculated in FY 2021 using an LCA-based method, revising the traditional calculation approach. To reduce emissions in Category 1, Mizuno will continue to promote the use of environmentally friendly materials such as recycled and plant-based materials, while also considering additional measures for further reductions.

＊ Calculations of purchased electricity emissions are location based.
＊ The calculation scope is the domestic Mizuno Group and overseas Mizuno Group.
＊ Scope 1: Greenhouse gas (GHG) emissions from a company’s direct operations, such as the in-house use of fuel
＊ Scope 2: A company’s indirect GHG emissions from purchased electricity, heat, and steam
＊ Scope 3: A company’s indirect GHG emissions coming from product manufacturing, transportation, employees’ business travel and commuting within the supply chain
＊ For Scopes 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 check mark has been assured by a third party in Japanese version of report.
＊ Scope1, 2
Direct and indirect GHG emissions from corporate activities as defined by the GHG Protocol
＊ Scope3 / 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
