Water resource management also achieved measurable results: compared with the 2022 baseline year, total group-wide water withdrawal decreased by 46.76 million liters, representing a reduction of 15%, reflecting the Company’s continuous efforts to enhance process efficiency and water recycling and reuse. In addition, compared with the baseline year, group-wide Scope 1 and Scope 2 greenhouse gas emissions were reduced by 9,037 metric tons of CO₂-equivalent, a reduction of as much as 37%, demonstrating significant achievements through the adoption of energy-saving technologies, equipment improvements, and the use of green electricity.
The Company also continues to maintain IECQ QC 080000 certification, demonstrating high standards in hazardous substance management and the implementation of comprehensive controls across design, procurement, and manufacturing processes. Overall, through systematic management and continuous innovation, the Company is steadily advancing the reduction of its environmental footprint and taking more resilient steps toward sustainable operations.

Responsible unit
The Company has set up a responsible unit to control, dispose of and report the business waste generated from the Company's operations, and disposes of waste in accordance with the local waste regulations of each site. The waste disposal methods are all implemented in accordance with local laws and regulations.
The waste management responsible departments of Sunon are:
-
Waste Classification: Each department
-
Waste Storage: Occupational Safety Team, Administration Department, Management Department of each factory
-
Waste Data Collection: Occupational Safety Team, Administration Department, Management Department of each factory
-
Waste Reporting: Occupational Safety Team, Management Department of each factory
-
Waste Treatment - Self-treatment: Each department
-
Waste Treatment - Outsourced Treatment: Occupational Safety Team, Administration Department, Management Department of each factory
The Company records the types, quantities and tracks the flow of hazardous business waste through paper forms, and measures the amount of waste generated by production capacity estimation and actual measurement. Hazardous business waste cannot be self-disposed in the factory due to technical or regulatory requirements, so it is entrusted to qualified external companies for transportation and disposal. For outsourced waste, after obtaining the documents issued by the external transportation company, the consistency with the measurement weight in the factory must be checked, and the tracking system in accordance with local government regulations must be followed to ensure that the transportation and disposal company disposes of the business waste according to the Company's requirements.
Other waste, such as employee domestic waste, is cleared and disposed of by qualified clearance and disposal agencies.
