PSP Achieves SET ESG Rating “A” for 2025, Reinforcing Commitment to Sustainable Growth Preparing to Integrate AI into Sustainability Data Management and Advance Toward FTSE Russell ESG Scores

P.S.P. Specialties Public Company Limited (PSP) has announced its 2025 sustainability assessment results from the Stock Exchange of Thailand (SET), achieving a SET ESG Rating of “A” with a total score of 71 points. PSP is one of only five companies within its industry group to receive an “A” rating this year. The achievement reflects the Company’s continued progress in sustainability development in line with its strategic objectives and serves as a key driver in maintaining its “A” rating while advancing toward FTSE Russell ESG Scores.

The Company continues to drive its sustainability agenda through green business strategies, greenhouse gas reduction initiatives across the supply chain, and the implementation of its ESG roadmap, alongside ongoing efforts to enhance the quality of life for employees, communities, and society. AI and technological innovations are also being integrated to strengthen sustainability data management and operational efficiency.

Mr. Sakesan Krongphanich, Deputy Chief Executive Officer of P.S.P. Specialties Public Company Limited (PSP), a leading integrated lubricant solutions provider, stated that this year’s assessment clearly demonstrates PSP’s commitment to good corporate governance, transparency, and accountability toward all stakeholder groups.

Achieving an “A” rating serves as an important milestone in reinforcing stakeholder confidence and encouraging the Company to further strengthen its environmental, social, and governance (ESG) practices. In particular, PSP delivered outstanding performance in the Environmental dimension, achieving a score of 89 points, significantly higher than the market average. The Company also achieved a full score of 100 points in Product Stewardship and 97 points in Resource Efficiency.

“Although PSP achieved scores above industry and market averages in the Environmental dimension, there remain opportunities for further enhancement in several key areas, including broader disclosure of environmental policies and impacts, the establishment of quantitative targets for hazardous waste reduction, and clearer disclosure of the Board’s oversight role in climate-related risks,” Mr Sakesan said.

“At the same time, the Social dimension remains an area requiring accelerated improvement, as the Company’s score this year remained significantly below both industry and market averages. Strengthening performance in this area will be a critical factor in PSP’s advancement toward higher sustainability standards under the SET ESG Ratings framework.”

In the Governance and Economic dimension, PSP also recognises opportunities for further development in several areas, including enhancing Board diversity and expertise, particularly in accounting and governance, strengthening enterprise risk management systems and emerging risk monitoring, as well as broadening oversight of sustainability-related risks across Environmental, Social, and Governance dimensions. The Company also aims to further improve transparency in governance and sustainability disclosures to reflect robust corporate governance standards and meet long-term investor expectations.

Mr. Sakesan added that achieving an “A” rating not only reflects PSP’s current operational standards, but also marks “the beginning of a new phase in sustainability advancement.” The Company plans to continue implementing its evolving sustainability roadmap in the coming years through initiatives such as the development of innovative products designed to reduce greenhouse gas emissions and minimise environmental impacts.

PSP is also integrating AI technologies into its manufacturing operations and data management processes to improve production efficiency and enhance the accuracy and speed of quality analytics. In addition, AI will support Sustainability and ESG Disclosure processes by consolidating, analysing, and managing environmental, social, and governance data from multiple sources within a unified system, reducing data duplication and errors while improving transparency and traceability.

These initiatives will support sustainability reporting and disclosure in accordance with both domestic and international reporting standards, including FTSE Russell ESG Scores, GRI, TCFD, and other recognised ESG frameworks.

The integration of AI into both manufacturing operations and sustainability data management will not only improve operational efficiency and product quality, but also strengthen competitiveness, customer and investor confidence, and support the Company’s long-term sustainable growth in a tangible manner.

In parallel, PSP is developing a human rights risk assessment framework aligned with the UN Guiding Principles on Business and Human Rights (UNGPs), including processes for identifying, assessing, preventing, and mitigating human rights risks, as well as establishing transparent and equitable grievance and remediation mechanisms.

The Company is also developing a Supply Chain ESG Due Diligence system to assess ESG-related risks among suppliers in accordance with international standards.

Looking ahead, PSP aims to further enhance its sustainability reporting practices to support FTSE Russell ESG Rating assessments and align with international standards. The Company will continue strengthening its Environmental, Governance, and Economic dimensions, while placing particular emphasis on improving its Social dimension.

These efforts are intended not only to improve sustainability assessment scores but also to create meaningful and sustainable positive impacts for employees, suppliers, stakeholders, communities, and society as a whole.
