Climate Change Action
The company is committed to transparency in its climate change initiatives by aligning its disclosures to the guidelines of the Task Force on Climate-Related Financial Disclosures (TCFD) and prioritizing sustainable environmental management. Additionally, the company aims to reduce greenhouse gas emissions per unit of output and enhance resource efficiency through various ongoing initiatives. This includes assessing its organizational carbon footprint to develop strategic plans for reducing greenhouse gas emissions. In 2024, the company engaged Advance Energy Plus Co., Ltd. as a consultant, with validation conducted by Bureau Veritas (Thailand) Co., Ltd.. As part of this effort, the company will achieve ISO 14064-1:2018 certification and receive official certification from the Thailand Greenhouse Gas Management Organization in March and May 2025, respectively.

Climate-Related Risk Management Procedures
In recognition of climate change, in 2024, CH. Karnchang conducted a Climate Change Risk Assessment in collaboration with its business partners. This study aimed to identify climate change-related risks (and opportunity) that could impact the business and the company’s operations, including both physical and transition risks. Examples of physical risks include rising average temperatures and increased rainfall, which may reduce construction productivity. The findings from this risk assessment will be integrated into CH. Karnchang business strategies, operational, and risk management plans to identify new opportunities and implement risk mitigation measures in both the short and long term. Additionally, the company will address a climate adaptation plan, integrating efforts across its risk management, business development, and sustainability teams. Governance oversight will be provided by the board of directors to enhance business resilience and maintain competitiveness. This approach also ensures alignment with stakeholder expectations, particularly those of investors. Furthermore, this initiative supports the goals of the Paris Agreement, aiming to limit global temperature increases to no more than 2°C. CH. Karnchang is aligning its efforts with the Nationally Determined Contributions (NDC).
Following the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), CH. Karnchang has identified five operational sites most vulnerable to climate-related risks across its value chain. These sites have been assessed for their physical and geographical characteristics using specialized risk assessment software. Key physical risks include heatwaves, sudden temperature drops, floods, thunderstorms, droughts, and wildfires. In terms of transition risks, significant challenges include regulatory and policy shifts, market dynamics, changing demand in the construction sector, and the growing impact of digital technology. The entire assessment process was conducted using scenario analysis based on the Shared Socioeconomic Pathways (SSP) framework, which evaluates factors such as population trends, economic growth, education, political developments, and technological advancements. The framework categorizes future scenarios into five possible pathways.
In its scenario analysis, CH. Karnchang evaluated 2 degree scenario in relation to business planning: A long term scenario where greenhouse gas emissions remain high or very high, with emissions nearly doubling by 2050. A long term scenario where greenhouse gas emissions are significantly reduced, ultimately reaching Net Zero by 2050. CH. Karnchang has identified key climate change risks and/or opportunities, both physical and transitional, integrating them into the company-wide risk management. Additionally, the company has outlined preliminary management strategies as follows:
The Risks of Climate Change | The strategy to incorporate climate change risks and opportunities |
---|---|
Physical risk | |
Risk of Water Shortage CH. Karnchang must consider the risk of water shortages within its supply chain and among its business partners, as water is a crucial resource in the production of construction materials. A shortage could reduce the availability of materials, disrupting construction activities and potentially delaying projects. Such disruptions may undermine stakeholder confidence in the company’s ability to meet project deadlines. To maintain production standards, additional costs may arise from securing alternative water sources. Furthermore, reliance on natural water supplies carries risks, as these sources are shared by multiple industries and projects. Types of Risks
|
|
Transition Risk | |
Changes in Laws and Carbon Pricing Changes in domestic laws and international cooperation are leading to the implementation of carbon taxation as a regulatory mechanism to mitigate the effects of climate change. If multiple countries adopt cross-border carbon pricing adjustments, such as the Carbon Border Adjustment Mechanism (CBAM), this could drive up construction material costs or cause delays in transportation when trading partners fail to meet the required standards or regulations. Types of Risks

Investment in Infrastructure The country’s current infrastructure investment presents a significant opportunity for Ch. Karnchang, as much of the existing infrastructure still requires continuous development and improvement. The primary focus is on transportation systems, including roads, expressways (highways), rail systems, air travel, and ports. Additionally, this project has the potential to lead to further investment in sustainable finance options, such as Green Bonds and Green Loans. Types of Risks
