Basic Concept

To help create a decarbonized society, Mizuno is committed to reducing energy consumption and energy-related greenhouse gas (GHG) emissions across the entire Group. Recognizing the importance of reducing greenhouse gas (GHG) emissions throughout the entire value chain, Mizuno is also working to lower GHG emissions associated with its products.
In April 2024, Mizunoʼs reduction targets were officially certified by the international initiative, the Science Based Targets (SBT) Initiative.

Energy Consumption

Mizuno is actively engaged in a variety of initiatives aimed at achieving its long-term environmental targets.
Key efforts include the installation of solar power systems at domestic factories and the expansion of LED lighting at offices both in Japan and overseas.
In particular, facilities with relatively high environmental impact—such as the headquarters building and factories—are being prioritized for strategic implementation to reduce energy consumption.
Additionally, Mizuno is gradually replacing its company vehicles with hybrid and other fuel-efficient models, and has introduced electric vehicles in some areas to evaluate their safety and environmental benefits.
All company vehicles are equipped with telematics systems, which visualize driving behavior. This not only encourages safer driving but also contributes to improved fuel efficiency and reduced CO2 emissions.

In fiscal year 2025, Mizunoʼs total domestic energy consumption was 82,746 GJ. Energy intensity improved by 0.2 points from the previous year, reaching 53.3.*

* 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)

* The calculation uses coefficients from the LCI database IDEA version 3.5.

* Historical performance data have been retrospectively revised due to updates to certain data and emission factors used in the calculations.

Key Initiatives for Reducing Energy Consumption

Mizuno is progressively converting lighting to LED to reduce energy consumption. Equipment used in our buildings is being upgraded to energy-efficient models as they come up for replacement. However, due to the difficulty in tracking the reduction amounts and types of energy for individual initiatives, there are currently no plans to disclose this information.

Energy-derived GHG Emissions

In fiscal year 2025, the Mizuno Group set a target for total energy-derived greenhouse gas (GHG) emissions of 10,640 t-CO2e (market-based), and achieved actual emissions of 10,377 t-CO2e.
This result exceeded the reduction target, indicating steady progress in reducing GHG emissions across the entire group. In FY2025, we further advanced the reduction of greenhouse gas emissions through the use of non-fossil fuel certificates.
Going forward, Mizuno will continue working to further reduce emissions through the introduction of energy-saving equipment, operational efficiency improvements, and the use of renewable energy sources.
No GHG emissions from biological sources, such as biomass combustion, have been identified.

* Energy intensity: Greenhouse gas emissions (t-CO2e) / Consolidated net sales (100 million yen).

* Due to rounding, the sum of individual items may not exactly match the total figures shown.

* Market-based emissions are calculated using the emission factors for electricity utilities published by Japanʼs Ministry of the Environment. For sites where electricity procurement data are unavailable and for overseas sites, location-based emission factors are applied.

* For certain sites, FY2024 actual data were used for FY2025 performance calculations.

* FY2025 emissions data for Japan (market-based) reflect the environmental value derived from the purchase of non-fossil fuel certificates.

* Historical performance data have been retrospectively revised due to updates to certain data and emission factors used in the calculations.

Other Indirect Greenhouse Gas Emissions

Mizuno recognizes that achieving a decarbonized society requires not only reducing greenhouse gas (GHG) emissions from its own operations, but also taking action across the entire value chain.

Accordingly, Mizuno calculates GHG emissions throughout its value chain based on Scope 3 standards defined by the GHG Protocol. In fiscal year 2025, Scope 3 emissions accounted for 97.57% of Mizunoʼs total GHG emissions.

To reduce these emissions, Mizuno is working with partners such as Sumitomo Warehouse, which operates its main distribution centers, to promote the installation of LED lighting. Additionally, Mizuno is advancing a modal shift in transportation between major logistics hubs in western and eastern Japan.

Within Scope 3, Category 1 (“Purchased Goods and Services”) and Category 12 (“End-of-Life Treatment of Sold Products”) together account for approximately 80% of total emissions.

In fiscal year 2021, Mizuno revised its calculation method for these categories, adopting an LCA-based approach.
To further reduce emissions in Category 1, Mizuno continues to promote the use of environmentally friendly materials such as recycled and plant-based resources, while collaborating with supply chain partners to explore additional reduction measures.

Co-creation with Stakeholders

Osaka Prefecture: Supply Chain CO2 Emissions Visualization Model Project

In preparation for Expo 2025 Osaka, Kansai, Osaka Prefecture is implementing the “Supply Chain CO2 Emissions Visualization Model Project”, aimed at accelerating the visualization of CO₂ emissions across entire supply chains. This initiative is commissioned to Boston Consulting Group, Inc., and based on a comprehensive assessment of industry and product applicability, Mizuno was selected as a participating company for fiscal year 2023.

As part of this project, Mizuno calculated and reported CO₂ emissions with a focus on the carbon footprint (CFP) of its apparel and equipment product categories. Since 2018, Mizuno has been proactively assessing CFP, particularly in its footwear segment. To further advance CFP calculation across a broader product portfolio, it became increasingly important to establish a methodology that balances accuracy with operational efficiency.
As a company headquartered in Osaka, Mizuno remains committed to collaborating with Osaka Prefecture to promote sustainable business practices moving forward.
