Tah Hsin Industrial's 2024 greenhouse gas inventory third-party assurance was conducted by Crowe (TW) CPAs, and the assurance report was obtained on 2025.6.6.

In 2024, the company's total group greenhouse gas emissions amounted to 4,631.155 metric tons CO₂e, representing a reduction of 128.136 metric tons CO₂e (a 2.69% decrease) compared to 4,759.291 metric tons CO₂e in 2023. The emissions for each category are as follows:
• Direct GHG emissions and removals (Category 1): 1,264.8129 metric tons CO₂e equivalent
• Indirect GHG emissions from imported energy (Category 2): 2,834.4722 metric tons CO₂ equivalent
• Indirect GHG emissions from transportation (Category 3): 110.9607 metric tons CO₂e equivalent
• Indirect GHG emissions from the use of products by the organization (Category 4): 420.9089 metric tons CO₂e equivalent
• Total emissions: 4,631.155 metric tons CO₂e equivalent

Compared to 2023, except for Category 3 (which was newly disclosed in 2024), Categories 1, 2, and 4 all recorded reductions in CO₂e emissions equivalent.

After two consecutive years of conducting voluntary GHG inventories and obtaining third-party assurance, Tah Hsin Industrial's future objectives in voluntary inventory and disclosure will focus on improving:
• The presentation of emissions data
• Communication with stakeholders
• Analysis of emission sources and formulation of reduction strategies

(Note: In the corporate news release dated May 14, 2025, regarding the “2023 Greenhouse Gas Inventory Third-Party Verification and Assurance,” it was stated that “…in 2024, the total direct and indirect greenhouse gas emissions across all Tah Hsin Industrial facilities amounted to 4,634.514 metric tons CO₂e, representing a 2.62% reduction from the base year.” The difference from the actual figures is due to the fact that, at the time of publication, the data had not yet undergone completion of third-party assurance.)
