Reduction of energy consumption and GHG emissions

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 CO2 emissions effectively requires doing so in collaboration with its entire value chain, Mizuno will put effort into reducing CO2 emissions generated when developing products.

Energy consumption

Mizuno currently makes various efforts with the aim of achieving its long-term environmental targets. One characteristic example is installing 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 2021 was 141,347 GJ. The intensity of energy consumption* was 123.7, a decrease of six points year on year.

Energy-derived CO2 emissions

In FY 2021, the Mizuno Group strove to achieve an annual target of reducing its total CO2 emissions from energy consumption by 2.5% year on year to 13,900 t-CO2. However, the Group’s actual CO2 emissions from energy consumption in FY 2021 were 14,537 t-CO2 mainly due to an increase in electricity and gasoline consumption caused by the relaxation of COVID-19 restrictions and the resumption of business activities both in Japan and abroad. From now on, Mizuno will introduce energy saving equipment and strive to enhance the efficiency of its operations in order to reduce its CO2 emissions.

Other indirect greenhouse gas emissions

Mizuno recognizes that helping create a decarbonized world requires it not only to reduce CO2 emissions it generates itself but also collaborate with its entire value chain in cutting CO2 emissions. Therefore, its calculations include CO2 emissions generated by its entire value chain based on the standards defined in Scope 3 of the GHG protocol.

In FY 2021, Mizuno’s Scope 3 CO2 emissions accounted for 96.64% of its total CO2 emissions. To reduce the amount of Scope 3 CO2 emissions, Mizuno is currently making the following efforts: 1) collaborating with Sumitomo Warehouse, which manages Mizuno’s main warehouses, in installing LED equipment at its warehouses; and 2) promoting a partial modal shift of transportation between its main warehouses located in West Japan and East Japan.

To accurately monitor Category 1 "Purchased products and services" and Category 12 "End-of-life treatment of sold products" which account for about 80% of Scope3, in FY 2021, Mizuno replaced the calculation method it had so far used with a new LCA-based calculation method. To reduce its Category 1 emissions, Mizuno will not only use materials with low environmental impacts, including recycled materials and plant-based materials, but also devise measures for further emissions reduction.

Using 100% recycled paper for shoe boxes

Since November 2021, as part of its efforts toward sustainability, Mizuno has been successively replacing boxes for shoes marketed in each category around the world with shoe boxes made of 100% recycled paper. This initiative is predicted to contribute to an annual CO2 emissions reduction of about 160 tons* compared with conventional shoe boxes.

By using 100% recycled paper for packages for shoes, which constitute one of its main product categories, Mizuno will contribute to reducing environmental impacts and building a sustainable, circular economy.
