CEO Message
CH. Karnchang Public Company Limited operates with a steadfast commitment to creating high-quality engineering and infrastructure, supporting the nation’s sustainable economic and social development.
CH. Karnchang recognizes that in today’s business landscape, success is no longer measured solely by financial performance, but must encompass environmental impact, social responsibility, and robust corporate governance. Consequently, the Board of Directors is dedicated to driving the organization under the ESG (Environment, Social, and Governance) framework and the United Nations Sustainable Development Goals (SDGs). These principles serve as a roadmap for steering the company toward sustainability and creating long-term value for our shareholders, stakeholders, and society throughout our entire value chain.
The past year, 2025, was another period where the business sector faced challenges from global economic volatility, climate change, resource risks, and the transition toward international sustainability regulations and standards. Nevertheless, through a clear vision, strong corporate governance, and the collective efforts of our Board, executives, and employees at all levels, CH. Karnchang has maintained stable, continuous, and responsible operations. We have elevated our sustainable development framework to align with the evolving expectations of all stakeholder groups.
In the Environmental dimension (Environment), CH. Karnchang prioritizes energy management, resource efficiency, and climate change mitigation. We strive to develop Green Construction processes by integrating innovation, technology, and best practices. Key initiatives include controlling and reducing greenhouse gas (GHG) emissions, systematic waste and construction material management, recycling and the use of circular resources, and monitoring air and water quality within project sites. These efforts reflect our commitment to sustainable business practices and align with SDG 7 (Affordable and Clean Energy), SDG 12 (Responsible Consumption and Production), and SDG 13 (Climate Action).
In the Social dimension (Social), CH. Karnchang is committed to human capital development—equipping our workforce with the knowledge and readiness to adapt to industry shifts—while placing the highest priority on occupational health and safety. We ensure a secure environment and a high quality of life for our employees and related parties. Furthermore, we promote a business approach that considers stakeholders in all dimensions through continuous community engagement. One of our flagship projects is the "Community Craftsman Innovation" project, now in its fifth consecutive year in collaboration with the National Innovation Agency (NIA) and the ChangeFusion Institute. This project aims to enhance skills, knowledge, and innovation among local artisans, creating business value alongside social and environmental responsibility, which leads to increased vocational capabilities, income generation, and the strengthening of the grassroots economy. This aligns with SDG 8 (Decent Work and Economic Growth) and SDG 11 (Sustainable Cities and Communities).
In the Governance dimension (Governance), CH. Karnchang adheres to the principles of good corporate governance, transparency, fairness, and comprehensive disclosure in line with international standards. We have systematically integrated ESG principles into our business operations, which reinforces stakeholder confidence in our sustainable management and oversight.
In 2025, CH. Karnchang received widespread recognition from leading organizations, including being rated "AA" in the SET ESG Ratings by the Stock Exchange of Thailand. We were honored with Outstanding CEO, Outstanding CFO, and Outstanding IR awards in the Property & Construction category at the IAA Awards for Listed Companies 2025, and selected as one of the ESG 100 for the ninth consecutive year by the Thaipat Institute. Additionally, we received an "Excellent" rating (CGR) from the Thai Institute of Directors (IOD), an "Excellent" score for our Annual General Meeting (AGM Checklist) from the Thai Investors Association, and environmental awards from the Mass Rapid Transit Authority of Thailand (MRTA). These accolades serve as tangible evidence of our commitment to responsible and sustainable business practices.
CH. Karnchang regularly conducts and reviews Materiality Assessments by considering business risks, opportunities, and stakeholder expectations across the value chain. This process leads to the definition of clear strategies, targets, and operational guidelines. In 2026, the Company will continue to enhance its systematic sustainability drive and improve data disclosure to align with international reporting frameworks, ensuring long-term trust and value creation.
On behalf of the Board of Directors and all employees, we would like to express our gratitude to our shareholders and all stakeholders for your continued trust and support. CH.
