Water Resources Management

Obtained ISO 46001:2019 Water Efficiency Management Systems Certification 

Chunghwa Telecom, an industry leader, took the initiative in March 2025 to obtain full-scale ISO 46001 Water Efficiency Management Systems certification. Following international standards, the Company systematically completed the inventory and assessment of high-risk water resource areas, established water usage performance indicators, and developed a comprehensive water efficiency management plan. Although Chunghwa Telecom is not a manufacturing enterprise, we recognize that implementing water resource efficiency management is a crucial step in addressing the uncertainties posed by climate change. By understanding the structure and sources of water usage, we will lay a significant foundation for enhancing the resilience of industrial water use in the future.

To ensure the effective utilization of water resources, we have established two conditions: setting a baseline year and cumulative reduction requirements. Through data management and continuous improvement mechanisms, we aim to enhance water efficiency, achieve sustainable resource utilization, and strengthen overall competitiveness.

Establishment of Baseline Year: 2020 is set as the baseline year, with a target of achieving a 1% reduction in water usage each year.

Cumulative Reduction Requirements: As of this year, if the cumulative reduction has reached 5%, the unit's annual water consumption must not exceed that of the previous year and should be maintained or further reduced.
