Water Consumption Statistics
With the shortage of global energy, Edison Opto places great emphasis on energy management to avoid unnecessary waste. The main types of energy used at its primary operating sites include liquefied petroleum gas, electricity, diesel, and gasoline. Regarding renewable energy, apart from Yangzhou Edison Opto adopting photovoltaic power generation, no other operating sites currently use renewable energy.

Note 1: Data coverage: All plants of Edison Opto Taipei (standalone entity) and all plants of the consolidated subsidiary Edison-Litek Opto.
Note 2: In 2023, ISO14064-1 guidance was launched and set as the base year, so the figures are more accurate compared to previous years; 2022 data was based on internal self-check results, and water intensity is not applicable.
Water Resource Reduction Quantitative Management Target
- Water resource reduction quantitative management: Setting 2023 as the base year, water intensity (water consumption per NT$1 million in production value) will decrease by 1.5% by 2025.
- Measures to achieve the target:
The Company internally implements water-saving measures, including installing sensor faucets and adjusting the water flow rate to reduce water consumption.
Water Resource Reduction Target Implementation Status
- Setting 2023 as the base year, water intensity decreased by 18.20% in 2024.
