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.

Consumption Analysis
The types of energy used by Sunon vary depending on the nature of each factory or office and include purchased electricity, photovoltaic power, diesel, gasoline, compressed natural gas, liquefied petroleum gas, and self-generated solar energy. Among these, purchased electricity is the primary source, accounting for approximately 55.47% of total energy consumption, followed by purchased photovoltaic power, which makes up around 40.64%. In 2024, Sunon’s total energy consumption reached 149,801.945 GJ, with an energy intensity of 10.244 GJ per million NT dollars of revenue.
Although the Company’s energy intensity slightly decreased in 2024 compared to the previous year due to increased annual revenue, it remained higher than the levels of the previous two years. This was mainly because, with the easing of the COVID-19 pandemic, employees made more frequent business trips using company vehicles, leading to higher consumption of gasoline and diesel. To address this, Sunon is considering the adoption of alternative energy vehicles when replacing company cars, in an effort to reduce reliance on gasoline and diesel fuels.

Note 1: Except for the calorific value of gasoline, diesel, and liquefied petroleum gas used in China factories, which adopts the calorific value announced locally in China, other energy uses the calorific value announced by Bureau of Energy, Ministry of Economic Affairs of Taiwan. Energy consumption is calculated by coverting energy usage x unit calorific value x 4.187 ÷ 1,000,000 into gigajoules (GJ).
Note 2: The company's sites are mostly manufacturing factorys, so each million revenue is selected as the energy intensity denominator.
Note 3: The 2023 data has been revised due to errors in the conversion values for purchased non-renewable energy sources (gasoline, diesel, compressed natural gas, and liquefied petroleum gas). As a result, the energy intensity and energy consumption percentages for that year have been adjusted accordingly.
