Water Resource Management
Coretronic primarily sources its water from municipal supplies, with usage mainly for air conditioning, domestic needs, and catering services. Water users include employees, visitors, and contractors. Since there is no process water demand, the environmental impact is relatively low. However, considering that water resources are a globally significant sustainability concern, Coretronic conducts a comprehensive water risk analysis using the Aqueduct Water Risk Atlas developed by the World Resources Institute (WRI). The analysis results indicate that Taiwan plants are classified as low to medium water risk areas (levels 1~2), while China plants face high water risk levels (levels 3~4). In light of the potential exacerbation of water scarcity risks due to climate change, Coretronic will continue to monitor water usage and water stress levels, regularly assess and revise water optimization strategies to ensure effective management and sustainable use of water resources. Currently, all sites implement water recycling and conservation measures to mitigate water-related impacts. The Company also promotes water-saving awareness to proactively prevent potential water shortages during dry seasons.
Water Resource Management Strategies
- Maximize water use efficiency
- Enhance awareness and water conservation efforts throughout the upstream and downstream value chain
- Set water-saving targets and regularly review progress to ensure achievement of these goals
- Continuously promote and implement various water conservation initiatives to realize tangible results
- Identify feasible water-saving measures through routine management and inspections
- Promote water resource education to improve stakeholders’ water literacy
Water Quality Management
Coretronic’s manufacturing process mainly focuses on product assembly, which does not require water usage and generate no process wastewater. The wastewater primarily originates from employee domestic sewage. In 2024, Coretronic discharged 0.27 million cubic meters of wastewater. All wastewater discharges comply with local regulatory requirements. Wastewater is strictly treated by local laws and regulations, with regular water quality testing conducted to monitor discharge conditions. This ensures that the discharge quality meets local regulatory standards. If any non-compliance is detected, a corrective action plan will be immediately implemented to prevent any adverse impact on natural water bodies and the ecological environment.
Water Usage Status
Although water resources are not a major environmental impact area in Coretronic’s operations, water issues have become a global concern. Coretronic has set water reduction targets and promoted water conservation through awareness campaigns and various saving and recycling measures. In 2024, water consumption at Taiwan plants decreased by 3% compared to 2023 and by 9% compared to 2021. At plants in China, water usage in 2024 dropped by 18% from 2023 and by 45% from 2021, both achieving short-term targets. Overall, total water consumption across Taiwan and China plants fell by 16% from 2023 and by 40% from 2021. Looking ahead, the Company will continue implementing proactive water-saving measures to mitigate the impacts of climate change.
Water Conservation Measures—Recycling Systems and Water-Saving Devices
- All Taiwan plants and Coretronic Optics (Suzhou) are equipped with recycling systems that primarily collect surface water, raft foundation water, air conditioning condensate, and rainwater for landscape irrigation and secondary domestic use. Each plant also implements water-saving measures such as adjusting the concentration of water replacement in air conditioning systems, installing water-saving devices on faucets (aerators and motion-sensor taps), monitoring water use in catering services, and reducing cleaning-related water consumption to achieve short-term water reduction targets.
- Since 2018, Coretronic has promoted various recycling and water-saving initiatives. As of 2024, the total volume of water saved and recycled reached 207,000 metric tons, resulting in a carbon reduction of 223.6 metric tons.
- In the 2024 Carbon Disclosure Project (CDP) “Water Security” questionnaire, Coretronic received an “A” leadership rating (A List).
