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.

Reduction Actions
Starting in 2022, Sunon has conducted annual greenhouse gas (GHG) inventories to regularly monitor and assess emissions at the organizational level. The year 2022 has also been designated as the base year, during which Scope 1 emissions totaled 2,148.659 tCO₂e, Scope 2 emissions were 22,281.1582 tCO₂e, and Scope 3 emissions amounted to 158,673.764 tCO₂e.
In 2023, Sunon submitted its commitment to the Science Based Targets initiative (SBTi) under the 1.5°C pathway. The Company has set a goal to reduce combined Scope 1 (direct emissions) and Scope 2 (indirect emissions from energy use) by 6.25% annually, aiming for a 50% reduction by 2030 and achieving net-zero emissions by 2050.
To reach net-zero emissions by 2050, Sunon has developed the following low-carbon transition plans:
- Actively engaging in voluntary carbon reduction by continuously developing energy-saving processes and equipment to enhance energy productivity and efficiency
- Gradually increasing the use of renewable energy each year and encouraging supply chain partners to participate in and support energy transition efforts.
- Investing in zero-emission technologies and participating in carbon offset programs to mitigate residual emissions that are currently unavoidable due to technological limitations.
- Incorporating recycled and low-carbon materials while continuously investing in research and development to improve motor efficiency and energy-saving capabilities.
As of 2024, Sunon has focused on replacing major energy-consuming equipment and increasing the use of renewable energy. Compared to the 2022 baseline, the company has already achieved a 37% reduction in carbon emissions, surpassing the reduction targets set by SBTi.
Looking ahead, Sunon will not only continue its own carbon reduction efforts, but also actively engage, communicate with, and encourage supply chain partners to join the mission—working together toward a net-zero future.
Internal carbon pricing
To achieve net-zero emissions by 2050, Sunon has developed a range of low-carbon transition plans. In formulating its internal carbon pricing mechanism, the company takes into account global carbon market prices, carbon fees and taxes imposed by greenhouse gas-related regulations, as well as the internal cost of carbon reduction. This internal carbon pricing tool is integrated into the assessment process for new equipment procurement. It considers the projected energy consumption over the equipment’s expected lifespan, as well as potential fugitive emissions from built-in refrigerants. By quantifying the carbon emission cost associated with each piece of equipment, the company can make more informed and rigorous investment decisions. This approach supports Sunon's efforts to effectively reduce greenhouse gas emissions through smarter procurement and planning.
