Greenhouse Gas Inventory
To ensure transparent operations and targeted carbon reduction, Juoku conducts annual greenhouse gas inventories to accurately record carbon emissions generated by its operational activities. Guided by the principles of “promoting resource recycling” and “reducing material consumption,” we systematically pursue reduction targets—from basic electricity usage to process improvements—and are taking concrete steps toward a low-carbon transition.
Juoku actively responds to the global trend toward net-zero emissions by conducting annual greenhouse gas inventories. Since our emissions primarily stem from electricity consumption, we have established an “Energy Conservation Task Force” specifically dedicated to promoting energy efficiency improvement projects.
To effectively promote energy-saving measures, Juoku has set a target of reducing energy consumption by 2% annually and aims to achieve a 14% reduction by 2030 compared to the base year (2023).
Total emissions for 2025 were 6,000.441 metric tons, a decrease of 1,197.7030 metric tons (16.64%) compared to the 7,198.144 metric tons recorded in the base year. The total emission intensity also decreased from 3.59 to 2.90, a reduction of 19.24%.
With our outstanding performance in 2025 and the early achievement of our 2030 carbon reduction targets, we will continue to optimize our energy mix, review our energy conservation goals, and move forward proactively and steadily toward our low-carbon transition goals.

Note 1: The inventory scope includes the Tainan Tech Park Plant, Tainan Plant, and Taipei Plant.
Note 2: Scope 1 refers to direct emission sources (e.g., gasoline, diesel, refrigerants); Scope 2 refers to energy indirect emission sources (electricity).
Note 3: Intensity = Emissions / Million NTD Revenue
Note 4: GWP values are based on the IPCC AR6 version; the electricity emission factor is based on the latest announcement by the Administration of Energy, Ministry of Economic Affairs. |
