What does "investment-based carbon neutrality" mean?

It refers to achieving a net-zero carbon balance by investing in environmental values, such as non-fossil certificates and carbon credits, equivalent to the amount of GHGs emitted by the organization.

Why did HIOKI include Scope 3 in the third-party verification?

To improve the reliability and comprehensiveness of the company's total environmental footprint, ensuring that calculation methods for categories like 'Purchased Goods' and 'Use of Sold Products' meet international standards.

What is the difference between Market-based and Location-based Scope 2 emissions?

Market-based emissions reflect the specific electricity contracts and renewable energy certificates purchased, while Location-based emissions reflect the average carbon intensity of the local power grid.

HIOKI has announced the early achievement of its 2025 target for Scope 1 and 2 carbon neutrality, with transparency ensured through rigorous third-party verification.

HIOKI E.E. Corporation (Headquarters: Ueda, Nagano; President: Takahiro Okazawa) has declared its commitment to achieving carbon neutrality for Scope 1 and Scope 2 emissions by 2025, marking the company’s 90th anniversary.

HIOKI recently underwent a third-party verification by SGS Japan Inc. based on ISO 14064-3:2019 regarding its greenhouse gas (GHG) emissions for fiscal year 2025. The company has successfully obtained a verification statement covering its consolidated organizational boundaries. This process confirmed the reliability of HIOKI's GHG emission calculations and independently certified the achievement of investment-based carbon neutrality for Scope 1 and Scope 2 (market-based).

Furthermore, the scope of verification was expanded this time to include non-energy-related Scope 1 emissions. By investing in an equivalent volume of non-fossil certificates, carbon-neutral certificates, and cancellation notices for the total GHG emissions identified, the company has secured its investment-based carbon neutral status. HIOKI also extended verification to all relevant categories of Scope 3, ensuring that calculation methods are appropriate and enhancing overall data transparency.

1. Details of Verified GHG Emissions (Consolidated) - Scope 1 (Energy-related): 746 t-CO2 - Scope 1 (Non-energy-related): 38 t-CO2 - Scope 2 (Market-based): 295 t-CO2 - Scope 2 (Location-based): 2,657 t-CO2 - Scope 3 (Relevant Categories 1-12): Totaling approximately 109,000 t-CO2 (Mainly Category 1: 52,256 and Category 11: 38,601)

2. Investment Volume for Carbon Neutrality - Non-fossil certificates (Scope 2): 317 t-CO2 - Carbon neutral certificates/Cancellation notices (Scope 1): 1,082 t-CO2

3. Reduction Initiatives - Scope 1: Electrification of the company fleet (EVs), investment in carbon-neutral gas, and acquisition of forest-derived J-Credits and VCS-certified credits. - Scope 2: Transitioning to 100% renewable energy at the Head Office and Sakaki Factory. A 2MW solar carport at the Head Office, completed in 2025, now provides approximately 40% of the site's electricity.

HIOKI remains committed to investing in energy-saving and energy-creating technologies to address emissions on a location-based scale while maintaining its verified market-based carbon neutrality.
