Water Resource Management

As climate change exacerbates the occurrence of extreme weather events, water-related issues such as droughts and floods are increasingly emerging across regions, indirectly impacting business operations. Consequently, water resource management has become a crucial sustainability issue for businesses in recent years. Our company also prioritizes water resource issues, establishing its first water conservation target in 2022, aiming to achieve an annual water conservation rate of 1.5% compared to the previous year. Annual water usage data compiled by our company and its subsidiaries must be verified by a third-party agency to ensure its reliability and validity. Data from 2022 to 2025 was audited in accordance with ISO14064-3 and certified by SGS.

Water Source and Water Conditions Analysis

As climate change intensifies extreme weather events, issues related to water resources—such as droughts and floods—have become increasingly frequent across various regions, indirectly impacting corporate operations. Consequently, water resource management has emerged in recent years as a critical sustainability issue for businesses. GIS also places strong emphasis on water-related issues. Using the “Aqueduct Water Risk Atlas” developed by the World Resources Institute, the Company identifies water risk levels at the locations of its factories and formulates corresponding management strategies and contingency plans based on the assessed risk level, in order to mitigate the potential impacts of water scarcity on business operations. Based on the 2025 assessment, no material water-related risks were identified.

Water Resource Usage

The primary water source used by GIS is municipal tap water, and all withdrawals comply with local regulations without causing significant environmental impact. In 2025, the Company's total water withdrawal was approximately 1,533.72 million liters, primarily for production processes, representing a 1.1% increase from 1,517 million liters in 2024.

Wastewater Management

Wastewater discharges at all GIS facilities comply with local discharge standards and are regularly tested by third-party agencies. No significant negative environmental impact has been caused by wastewater discharge at any factory.

Water Conservation Projects

GIS implements water conservation projects on an annual basis. In 2022, the Company established its first water-saving target, aiming to improve the water conservation rate by 1.5% each year compared with the previous year. Based on this target, a minimum rate of 42.23% should be achieved by 2025. In 2025, GIS launched 11 water-saving projects, which included wastewater and RO concentrate recovery and reuse, MAU condensate recovery, and adjustments to domestic water supply. These initiatives resulted in a total water savings of 692 million liters, achieving a water-saving rate of 45.12% thus meeting the set target, exceeding the 2025 target by 2.89%.

Water Resource Targets and Performance

From 2022 to 2025, the company implemented 40 water conservation projects, saving a total of 2,534 million liters of water. GIS's water conservation projects over the years are as follows:
