Green Operations
Actron is committed to the implementation of environmental protection in the production process. For the production value chain, products from the stages of incoming raw material to production completion are within the scope of our environmental protection. To realize our principles, we integrate the environmental safety and health policy into our operational strategy, and we aim to reach the goal of zero emissions starting from pollution control. Actron has obtained ISO 14001:2015 certification and uses it as the framework for the company's environmental management. In response to the carbon reduction demands arising from climate change, Actron continues its efforts towards energy conservation and carbon reduction. We also initiated the implementation of ISO 14064-1:2018 Greenhouse Gas Inventory Standard. This involves the design, development, management, and reporting of greenhouse gas inventories, in line with principles and requirements. These measures are aimed at managing carbon emissions resulting from organizational operations, thereby enhancing environmental performance and operational efficiency.
Energy Management
Taiwan has limited energy resources, making energy conservation a key focus of government policy. As a major energy user regulated by the Energy Administration, Ministry of Economic Affairs, Actron adopts the PDCA cycle to strengthen its energy management system and improve energy efficiency, while enhancing regulatory compliance and internal oversight.
Due to the nature of the manufacturing industry, Actron’s energy consumption is primarily attributable to production and facility utility equipment. In 2025, electricity consumption totaled 33,178,468 kWh (119,442 GJ). The Company’s energy sources included electricity, diesel, and gasoline, with total energy consumption of 120,372 GJ, of which grid electricity accounted for 99%. To reduce energy consumption and the environmental impacts of its operations, Actron monitors electricity intensity as a key performance indicator. In 2025, electricity consumption per NT$ million of revenue was 4,093.093 kWh, down 5.3% from 4,319.889 kWh in 2024 and 62.31% from 10,859.69 kWh in the 2019 base year.
- Stage 1- Energy Saving: We actively promote energy saving and power saving actions in the factories in terms of the lighting, air conditioning, production energy and air compressor, in order to reduce the unit product power consumption. We further centralized the machines and time to perform production according to the order demands, thereby integrating the energy saving and production operations of Actron.
- Second Stage- Energy Creation: In response to the “Renewable Energy Development Act”, we voluntarily constructed solar power equipment with a total capacity of 464kW at Nankan Plant I-III. In 2025, Actron generated 523,707 kWh of solar power, all of which was sold to the grid under a feed-in tariff (FIT) scheme. Actron uses high-efficiency monocrystalline solar modules with VPC certification (Note 1). The solar panels are installed in a dual-slope configuration, reducing the need for maintenance walkways and allowing more space for solar panel installation. In 2025, the average daily solar power generation was 3.09 kWh per kW of installed capacity.
- Stage 3- Energy Storage Control: We utilize smart electric meter to “visualize power consumption” to understand the state of power consumption, in order to perform electricity saving, adjusting the time of use for electricity bill and usage amount feedback, in order to facilitate the management of power usage and effectively achieve electricity saving. The power consumption at peak time is moved to off-peak time, achieving an electricity load of “peak reduction with off-peak addition”. In support of the government’s electricity conservation initiatives, Actron participates in Taipower’s Planned Demand Reduction Program (8 Days per Month) during its annual maintenance period. In August 2025, Actron achieved an actual demand reduction of 12,796 kW. In addition, Actron utilizes its generators to participate in Taipower’s Electricity Trading Platform – Fast Response Reserve Service, achieving an actual demand reduction of 72,420 kW in 2025 and helping Taipower manage peak electricity demand.
- Stage 4- Green Energy: To cope with international carbon reduction trends, Actron is committed to using 50% green energy by 2030. The annual green electricity demand is 28,224,720kW, and the demand for the purchase of offshore wind power generation for 20 years (2030-2049) is 7.5MW.
Greenhouse Gas Inventory
In the realm of environmental, health, safety, and energy policies, Actron has declared that greenhouse gas reduction is the company's responsibility and strategy for sustainable operation. In order to ensure the effectiveness of the environmental system, Actron has been promoting the ISO 14064-1:2018 standard for greenhouse gas inventory. The company voluntarily disclosed the results from 2015 to 2020, covering categories one and two. In 2021, Actron established the ISO 14064-1:2018 Greenhouse Gas Inventory Standard, with the inventory year being 2021, and expanded the inventory to include categories three to six. Consequently, 2021 became the new baseline year for greenhouse gas inventory. The inventory follows the guidelines of the Ministry of Environment for greenhouse gas emission reporting and management, using the operational control method and emission coefficients for calculation. Through annual assessments of carbon reduction efforts and long-term tracking of energy consumption, Actron monitors five types of greenhouse gases: CO2, N2O, CH4, HFCS, and PFCs, while SF6 and NF3 are not utilized.
Actron conducts its greenhouse gas (GHG) inventory using the emission factors published by Taiwan’s Ministry of Environment and the Global Warming Potential (GWP) values from the IPCC Sixth Assessment Report (2021). In 2025, Actron’s total GHG emissions amounted to 76,042 metric tons of CO₂e (Categories 1–6). GHG emissions intensity per NT$ million of revenue was 9.381 metric tons CO₂e, down 11.70% from 10.624 metric tons CO₂e in 2024.
Since its product transformation in 2018, Actron has gradually reduced the use of CF₄ and N₂O in dry etching. While these gases are used in the production of conventional rectifier diodes, the mass production of high-efficiency diodes (LLD) and ultra-high-efficiency diodes (ULLD) does not require CF₄ or N₂O for etching. As the product mix continues to shift toward LLD and ULLD, the use of CF₄ and N₂O will gradually decrease, significantly reducing GHG emissions.
In 2025, Category 1 emissions totaled 54,886 metric tons CO₂e (72.18%), while Category 2 emissions totaled 15,050 metric tons CO₂e (19.79%). By GHG type, perfluorocarbons (PFCs) accounted for the largest share at 53,962 metric tons CO₂e (70.96%), followed by carbon dioxide (CO₂) at 21,225 metric tons CO₂e (27.91%).
Note: PFCs emissions mainly result from the use of CF₄ in the dry etching process, with CF₄ consumption set at 0.0508 kg per unit of product. GWP values are based on the IPCC Sixth Assessment Report (AR6).
To effectively reduce greenhouse gas emissions, Actron has developed a GHG reduction strategy with short, medium, and long-term targets to minimize environmental impacts through measurable goals and product transformation. The Company is gradually phasing out equipment using CF₄ and N₂O. In 2025, CF₄ and N₂O emissions decreased by 5,305 metric tons CO₂e compared with 2024. In addition, CF₄ and N₂O abatement equipment was installed for the dry etching process in 2025, which is expected to reduce related GHG emissions by 90%. Actron aims to reduce total GHG emissions by 50% by 2030 from the 2021 baseline.
