Greenhouse Gas Management
Since 2009, NTC has established a greenhouse gas inventory mechanism by following ISO 14064-1 greenhouse gas inventory standards and the "Guidelines for Greenhouse Gas Emission Verification and Registration" issued by the Environmental Protection Administration. The company regularly inventories Scope 1 and Scope 2 emissions within the wafer fab and obtains verification from third-party verification agencies.In 2023, Nuvoton implemented several measures to reduce greenhouse gas emissions . Consequently, according to third-party verification, the total Scope 1 and Scope 2 greenhouse gas emissions for Nuvoton in 2023 were 138,144 t-CO2e, a reduction of 35,728 t-CO2e (20.5%) compared to 2022. The total Scope 1 emissions in 2023 were 39,794 t-CO2e; the total Scope 2 emissions were 98,350 t-CO2e; the total Scope 3 emissions were 724,911 t-CO2e.
Based on the fact that emissions from the process gases generated by NTC account for more than 90% of the carbon emissions in Scope 1, the reduction of greenhouse gas emissions from the processes has been set as the primary reduction target. The main reduction strategy has evolved from initially optimizing processes by replacing process gases to the current approach of installing fluorinated gas reduction equipment at the process end, while also improving the processing efficiency of the reduction equipment and gradually increasing its quantity each year.

| Item | 2023 Target | 2023 Actual Results | Future Goals |
|---|---|---|---|
| Fluorinated Gas Reduction Equipment at Process End | Complete the installation of three fluorinated gas reduction units at the process end, with plans to increase the reduction amount annually | Achieve a 48% annual reduction in fluorinated gas emissions | Plan to add the fourth and fifth units in 2024, achieving a 60% annual reduction compared to the 2020 baseline |
Since 2023, NTCJ has been conducting third-party verification in accordance with the ISO 14064-1 standard, similar to Taiwan, and has obtained a verification statement to ensure the credibility and quality of the inventory data and reports. From 2023 to early 2024, NTCJ will conduct carbon emission surveys of suppliers in preparation for ISO 14064-1 certification in 2024.
