Annual performance
The Company has continued to demonstrate a strong commitment to environmental management and sustainable governance, responding to global climate action demands with tangible results. During the year, the Company conducted a comprehensive group-wide greenhouse gas inventory and obtained external third-party verification, ensuring data transparency and reliability, and laying a solid foundation for the formulation of subsequent carbon reduction strategies and performance tracking.
In terms of energy transition, the group-wide proportion of green electricity usage increased to 42.19%, with a total of 17.55 million kWh of renewable energy adopted, effectively reducing the Company’s operational carbon footprint and supporting the development of the renewable energy market. 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.

Water Withdrawal and Consumption
To meet customer requirements, all of Sunon’s production facilities use 100% tap water as their source, with a total water withdrawal of 265.044 million liters in 2024. Due to the nature of the production processes, no industrial wastewater is generated—only domestic wastewater is discharged, which does not negatively impact the environment or cause water pollution.
Despite this, Sunon has proactively implemented several water-saving measures, including the installation of automatic sensor water dispensers, water-saving faucets, low-flow toilets, and adjustments to toilet tank fill volume. The company also continuously promotes water conservation awareness among employees. As a result, compared to the base year of 2022, total water withdrawal across the group has been reduced by approximately 15%.
Moving forward, Sunon will continue to comply with relevant local government regulations, subject itself to strict oversight, and fully embrace the environmental protection principles of sustainable water resource management.

Note 1: The disclosure scope was all sites in this report and U.S. subsidiary and European subsidiary. However, the Indian subsidiary was not included in the inventory because it is a leased office and unable to obtain water consumption information.
Note 2: Identification method for water-stressed regions: Using the WRI (World Resources Institute) Water Risk Atlas mapping tool, if the water stress of the region is identified as medium-high or above, it is considered a water-stressed region. This year's assessment of water-stressed regions includes Kunshan Guangxing Factory and U.S. subsidiary.
