According to the results of the Company's greenhouse gas inventory, the boundary set covers the plant building of the Company's Nanke Plant, the geographical location range is the plant of the Science Park in the new urban area of Tainan City, and the scope of the inventory is Both Category 1 and Category 2. As the annual greenhouse gas emissions are lower than the EPA's control standards, they are exempt from the requirement of entrusting third parties to conduct verification, but for self-management requirements, they still conduct in-plant self-inventory on an annual basis according to the industrial greenhouse gas inventory form provided by the Southern Science and Industrial Park Authority。

The Company's total greenhouse gas emissions in 2017 were 2,706.52 metric tons of CO2e, as explained below (in 2017, due to the increase in order production capacity, the purchased electricity part increased from the previous year)：

• Direct greenhouse gas emissions, such as official vehicles, generator testing, etc., have a direct emission of 38.83 metric tons of CO2e. Approximately 1.43% of total emissions。
• Indirect greenhouse gas emissions, the main source of emissions is purchased electricity, indirect energy emissions of 2667.69 metric tons of CO2e. Approximately 98.57% of total emissions。

The Company's total greenhouse gas emissions in 2018 were 2,935.22 metric tons of CO2e, as explained below (in 2018, due to the increase in equipment demand for orders, the purchased power part increased compared with the previous year)：

• Direct greenhouse gas emissions, such as official vehicles, generator testing, etc., have a direct emission of 40.15 tons of CO2e. Approximately 1.36% of total emissions。
• Indirect greenhouse gas emissions, the main source of emissions is purchased electricity, indirect energy emissions of 2895.07 metric tons of CO2e. About 98.64% of total emissions。

Specific actions to reduce the Company's greenhouse gas emissions：

• Specific actions to reduce the Company's greenhouse gas emissions。
• Replace the water equipment with a provincial water label product。
• Encourage colleagues to take stairs instead and reduce elevator use to reduce electricity use and carbon dioxide emissions。
• Implement a traffic car ride-sharing system, and prohibit official vehicles from traveling between The Shugu Factory in Tainan City and the Tucheng Headquarters in New Taipei City。
• The heat exhaust and cooling equipment in the factory area is improved to reduce the temperature in the factory and reduce the energy consumption of air-conditioning equipment。
• The roof is fully coated with thermal insulation paint, which effectively improves the sweltering heat in the factory。
• Replace mercury projection lighting with LED lights。
• The air conditioner in the office building is automatically turned off at regular intervals, and the temperature in each district is fixed at 27 °C。
• The whole plant air compressor pipeline leakage maintenance, to avoid the air compressor excess energy consumption。
• The cooling water tower strengthens the amount and frequency of cleaning, and increases the cooling efficiency。

Total water consumption and total waste are revealed：

• Total water consumption in 2018 was 49,219 metric tons; The total waste was 5,115 tonnes。
• Total water consumption in 2019 was 62,956 tonnes; The total waste was 6,240 metric tons。
