The DIC Group Receives Third-Party Certification that the Methodology It Uses
to Calculate Product Carbon Footprint Conforms with International Standards —Creating a global system for providing credible product carbon footprint data—

Tokyo, Japan—DIC Corporation announced today that the methodology it, along with wholly owned subsidiary Sun Chemical Corporation, uses to calculate product carbon footprint¹ for DIC Group products has received third-party certification. This certification confirms conformance with key international standards such as ISO 14067:2019² and the TfS PCF Guideline.³ This third-party certification - conducted by the Ramboll Group A/S headquartered in Copenhagen, Denmark, which boasts multidisciplinary expertise in the area of environmental impact assessment - verifies that the product carbon footprint data provided by the DIC Group aligns with global criteria for reliability, transparency, and comparability.

Given the heightened awareness of achieving carbon neutrality, companies are working to lower greenhouse gas emissions across their supply chain and to disclose related information with a high degree of transparency but most importantly accuracy. Product carbon footprint, which measures product-specific greenhouse gas emissions, is an important indicator in decision making regarding, for example, the reduction of greenhouse gas emissions, product procurement and sustainability disclosure. However, differences in methodologies and calculation scope would lead to inconsistencies and errors in results, undermining both reliability and comparability.

In response, the DIC Group developed a methodology for calculating product carbon footprint, for which it has now received third-party certification. This third-party certification validates that the methodology conforms with ISO 14040:2021,⁴ ISO 14044:2018,⁵ ISO 14067:2019 and Version 3.0 of the TfS PCF Guideline. It also confirms that the methodology is scientifically valid, highly transparent, and aligned with global best practices in life cycle assessment and carbon accounting.

The DIC Group has identified “contribution to the realization of carbon neutrality” as a material issue that it must address. Obtaining this third-party certification for its product carbon footprint calculation methodology ensures the Group’s ability to provide more reliable product carbon footprint data, thereby assisting customers and other stakeholders in their efforts to make more sustainable product choices.

¹　Product Carbon Footprint (PCF) is an indicator that represents the amount of greenhouse gas emissions— measured in CO₂ equivalent—generated over the life cycle of a product, from raw material procurement through disposal and recycling. The DIC Group provides PCF data for processes from raw material extraction to product shipment, covering the “cradle-to-gate” stage.
²　ISO 14067:2019, published by the International Organization for Standardization, is the international standard for calculating the carbon footprint of products.
³　The TfS PCF Guideline was developed by Together for Sustainability (TfS), a nonprofit established principally by leading European chemicals companies, to standardize product carbon footprint (PCF) calculations across the chemicals industry.
⁴　ISO 14040:2021 is the international standard for principles and frameworks for life cycle assessments.
⁵　14044:2018 is the international standard for requirements and guidelines for conducting life cycle assessments.
