Environmental Data List

GHG emissions (Scope 1 and 2)

We, Pioneer Group are working to achieve a 42% reduction in GHG emissions by the fiscal year ending March 31, 2031 (4.2% reduction/year based on a 1.5°C scenario) based on the fiscal year ended March 31, 2021, and this near-term target has been certified by SBTi.
Data for the fiscal year ended March 2026 has been subject to third-party assurance.

Third-Party Assurance

For Scope 1 emissions, emissions are calculated using the emission factors specified under the Japanese Ministry of the Environment's Greenhouse Gas Emissions Calculation, Reporting, and Disclosure System, based on the quantity of each fuel consumed. For Scope 2 emissions, under the location-based method, the national average emission factor of the same system is applied to domestic sites, while country- and region-specific emission factors published by the International Energy Agency (IEA) are applied to overseas sites. Under the market-based method, emission factors specific to electricity suppliers and electricity supply plans are used.

For fiscal year 2026 (ended March 31, 2026), Scope 1 emission factors for both domestic and overseas sites were based on the Ministry of the Environment's List of Emission Factors by Gas Suppliers (for FY2026 Reporting) and Greenhouse Gas Emissions Calculation and Reporting Manual (Ver. 6.1, March 2026). For Scope 2 emissions, country-specific emission factors from the IEA Emission Factors 2025 database were used under the location-based method. Under the market-based method, domestic sites applied electricity product-specific emission factors published by retail electricity suppliers, as listed in the Ministry of the Environment's List of Emission Factors by Electricity Suppliers (for FY2026 Reporting). Overseas sites used emission factors associated with their contracted electricity products where available; otherwise, location-based emission factors were applied. For certain sites where the necessary data could not be obtained, intensity data from representative sites were used as proxies.

We started conducting Scope 1 and 2 emissions calculations since 2008, and recalculated them in 2024 after reviewing the target boundary and calculation method. As a result, data for the fiscal years ended March 31, 2022 and 2023 are not available.

Unit: ton-CO₂

Scope 1: An organization’s direct GHG emissions (fuel combustion, industrial processes, etc.)
Scope 2: Indirect emissions associated with the use of electricity, heat, or steam supplied from another company.

GHG emissions (Scope 3)

To reduce environmental impacts across the supply chain, we calculate and disclose Scope 3 greenhouse gas (GHG) emissions.
Emissions are calculated based on the GHG Protocol and the Ministry of the Environment, Japan's Basic Guidelines on Accounting for GHG Emissions Throughout the Supply Chain. Emission factors are sourced from the Ministry of the Environment's Emission Factor Database and the IDEA database.

For FY2026 (the fiscal year ended March 2026), we used Version 3.6 of the Ministry of the Environment's Emission Factor Database and LCI Database IDEA Version 3.5 (AIST).

In addition, for Scope 3 Category 1, we promote emissions reductions across our supply chain through supplier engagement. We encourage key suppliers representing 10% of our Category 1 emissions to establish SBTi-aligned emission reduction targets and provide support to help them achieve those targets.

This near-term target has been validated by the Science Based Targets initiative (SBTi).
In addition, data for the fiscal year ended March 2026 has been independently assured by a third-party assurance provider.

Categories 8, 10, and 13-15 are excluded from the calculation and assurance scope, as no relevant activities exist within our business operations.

Third-Party Assurance

We have been calculating Scope 3 since 2011, and as with Scope 1 and 2, we have recalculated in 2024 after reviewing the target boundary and calculation method.
As a result, data for the fiscal years ended March 31, 2022 and 2023 are not available.
In addition, since reduction targets for Scope 3 GHG emissions are set by Category 1 and 11 activities, we have not set targets for each category. No past results are available for supplier engagement in Category 1, as the target was set in 2024.

Unit: t-CO₂e

Scope 3: Indirect emissions other than Scope 1 and 2 (emissions by other companies related to the activities of the business)

Note: The impact of revisions to calculation methodologies and improvements in data quality implemented in fiscal year 2026 (ended March 31, 2026) was evaluated against the base year emissions and confirmed to be below the Company's recalculation threshold of ±5%. Accordingly, no recalculation of base year emissions has been performed in accordance with the principles of the GHG Protocol and SBTi. The impact of such changes will continue to be monitored and managed on a cumulative basis, and the base year emissions will be recalculated as appropriate if the established threshold is exceeded.

Calculated as a percentage of the Group's total component procurement spend.

To promote decarbonization across our supply chain, we launched a supplier engagement initiative to encourage our suppliers to reduce the CO₂ emissions. In FY2026 (ended March 31, 2026), we engaged in direct dialogue with suppliers representing approximately 15% of the Group's total procurement spend, discussing topics such as the establishment of decarbonization targets and the calculation of CO₂ emissions. Following these discussions, suppliers representing approximately 1% of the Group's total procurement spend established emissions reduction targets aligned with the SBTi framework.

We monitor emissions across all Scope 3 categories and are driving reduction initiatives focused on Categories 1 and 11, which together account for more than 90% of our total Scope 3 emissions. Going forward, we plan to review and update our targets as appropriate while monitoring emissions reduction progress and changes in our business activities and operations.

Energy Consumption

We actively promote the introduction and utilization of renewable energy through purchasing electricity derived from renewable energy sources, implementing power purchase agreements (PPAs), and introducing green electricity plans etc.

Covering domestic and international sites where relevant data can be obtained.

The renewable energy ratio is calculated as the one of the renewable energy purchased/generated amounts to the electricity used amounts.

Environmental Data of Major Sites

Data on “Energy Consumption,” “Waste and Valuables,” “Chemical Substances Emissions,” and “Water Usage” are collected for each major business site, and progress is managed.

ISO14001 Certification Status

Employee coverage calculated as the ratio of the number of employees at ISO 14001 certified sites divided by the total number of employees.

The current list of applicable sites is provided on the Environmental Management page.
