Creating Positive Environmental Impact

Total water withdrawal in 2025 was 368.59 million liters (ML). As the global business expanded, total production hours increased significantly, resulting in a rise in total water withdrawal of approximately 21.5% compared to the 2023 base year (303.36 ML). Regarding water discharge, the total discharge volume in 2025 was 271.18 ML, a slight increase of 2.62 ML (approximately 0.98%) compared to 2023 (268.56 ML). Regarding the calculation methodology, the discharge volumes for METC and MEVN were calculated based on metering data from external water treatment plants, while for other operational sites, a scientific estimation was made by adopting 90% of the water withdrawal volume as the discharge volume, in accordance with guidelines from the Ministry of the Environment. In terms of water resource recovery and reuse, the Taiwan Headquarters has installed a rainwater harvesting system and uses the collected rainwater directly for irrigation of campus vegetation to improve water resource efficiency. However, due to its single-purpose use and exclusion from formal water management systems, there are currently no statistics available on the volume of recycled water.

 

The water intensity for 2025 (calculated as the Groupʼs total water intake L/the Groupʼs total annual working hours) was 13.38, a 12.72% decrease from the 2023 baseline yearʼs water intensity of 15.33, indicating that water conservation efforts have yielded tangible results despite increases in production capacity and working hours. The proportion of water abstracted in water-stressed areas was higher than
in 2023 due to the continued growth in revenue at MEVN; its water intensity in 2025 was 8.56, which is still 30.35% lower than its baseline year (12.29).

With the implementation of UL 2799, waste classification and statistics have become more comprehensive and accurate. In 2025, total waste generation amounted to 2,328.16 metric tons (all disposed off-site), an increase of 1,610.69 metric tons (compared to the base year of 2023 a 224.5% increase). The primary reason being that, in addition to revenue in 2025 grew by 26.71% compared to 2023 the number of employees in 2025 also increased by 87.24% compared to the base year. Furthermore due to the implementation of the UL 2799 mechanism, which improved the quality of waste inventory and statistical data the output of municipal solid waste and on-site food waste was measured using actual weighing methods. Consequently the actual waste output significantly increased compared to the estimated figures from the base year. The waste intensity (metric tons / million yuan in revenue) was 0.0501, an increase of 0.0305 (an increase of 156.09%) compared to the base year. By disposal method, a total of 1,803.28 tons were recycled and reused, achieving a recycling rate of 77.46%.
