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 43.94%, with a total of 21.05 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 22.29 million liters, representing an approximately 27% reduction of water use intensity, 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 9,872 metric tons of CO₂-equivalent, a reduction of as much as 40%, 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.

Reducing Energy Consumption
With the steep rise in energy costs, how the company implements effective energy management and reduces energy expenses will be a critical issue in the years ahead.
In recent years, Sunon has launched several energy-saving initiatives. These include upgrading or replacing high energy-consuming equipment with newer, energy-efficient technologies, introducing energy-saving air compressors, and installing heat pump systems in burn-in chambers used for thermal cycling tests, which require continuous high-temperature operation.
All operating locations are actively implementing comprehensive energy management measures. Notably, in 2024, the Kaohsiung headquarters became the first site to adopt the ISO 50001 Energy Management System, which was successfully certified by an independent third-party verification provider.
Looking ahead, Sunon plans to gradually roll out the ISO 50001 Energy Management System across all operational sites. This will enable more precise monitoring and control of energy usage, strengthening the company’s overall energy management capabilities.
• Energy Saving Promotion
The Company actively promotes energy conservation in its office spaces through a variety of initiatives. These include turning off non-essential lights for one hour during lunch breaks, maintaining air conditioning at optimal temperatures, and encouraging the use of LED lighting and energy-efficient equipment. Employees are regularly reminded to switch off unnecessary devices—such as lights, air conditioning, and copiers—when leaving the office. Through these practical energy-saving actions, unnecessary energy consumption is reduced, and employees gradually develop long-term habits of energy-conscious behavior.
Every year, on the last Saturday of March, Sunon’s headquarters leads the participation of its global offices and factories in the “Earth Hour” event. From 8:30 PM to 9:30 PM, all non-essential power is turned off as part of a worldwide initiative to protect the planet. Employees, along with their families and friends, are encouraged to join this meaningful event to take action for the Earth and our shared home.
Renewable Energy Use
The Kunshan Guangxing Plant installed a solar power generation system in 2013 and introduced renewable energy through self-generation and self-consumption in order to reduce the use of conventional electricity and lower GHG emissions. In addition, the Beihai Sunon Plant and Beihai Lizhun Plant began purchasing renewable energy in 2023 to gradually increase the proportion of renewable energy used.
This year, Sunon's total self-generated and purchased renewable energy use reached 21,051,685 kWh, accounting for 43.96% of the Company's total electricity consumption and reducing emissions by approximately 11,170 tCO2e. Going forward, the Company will continue to increase the proportion of renewable energy used and gradually expand the adoption of low-carbon energy in order to reduce the environmental impacts of its operating activities.
Note 1: All renewable energy used by the Company is solar power.
Note 2: The 2024 usage data for the Beihai Sunon Plant and Beihai Lizhun Plant have been revised based on the GHG inventory results.
Note 3: Carbon reduction benefit = renewable energy use (kWh) × the latest electricity emissions factor published in China for the relevant year / 1,000.
