Water Management

TCC has established Water Management Commitment, committed to pursuing sustainable water resource utilization, enhancing water resource management, and improving water efficiency. Pledged to reduce water withdrawal and consumption, comply with relevant regulatory standards, rigorously monitor the quality of discharged water to prevent harm to ecosystems, water bodies, and human health due to wastewater, and ensure that employees and local residents have access to clean water

Water Risk Management Programs

Assessment of Future Water Availability and Water-Related Dependency and Impact Risks：Although the cement industry utilizes a dry process and is not considered water-intensive, TCC proactively strengthens its water management systems. To comprehensively grasp water resource risks, TCC follows the TNFD framework, prioritizing the Cement and Environmental Protection Business (Asia) and Cement and Environmental Protection Business (Europe-Africa) groups to identify the dependencies and impacts of its global quarries and operating sites on water flow and quality. Using the WRI Aqueduct tool, TCC assessed water stress across sites in Taiwan, Mainland China, Europe, Türkiye, and Africa, identifying 108 sites in high water stress regions. Physical risks primarily involve potential shortages leading to rationing and production halts; transition risks encompass stricter wastewater discharge regulations, where non-compliance could result in fines or operational suspensions. Poor management could also disrupt surrounding domestic, agricultural, and ecological water supplies, impacting local communities and the environment. To effectively manage consumption, TCC's cement plants in Taiwan and Mainland China have utilized a dedicated water footprint platform since 2022 to monitor supply, consumption, recycled water, and wastewater discharge data in real time, enabling instantaneous recycling rate calculations. TCC also actively implements ISO 46001 water efficiency management certification and ISO 14046 water footprint verification. Cement plants in Taiwan and Molicel (Tainan plant) are subject to water consumption fees. In 2025, their water recycling rates reached 98.6% and 51.8%, respectively, both exceeding the Water Resources Agency's industry benchmarks.

Assessment of future water quality-related risks：TCC utilizes the internationally recognized nature risk assessment tool, ENCORE, to evaluate "Ecosystem Service Dependencies" and "Ecosystem Service Impacts" across all group-owned operating sites (including quarries, cement plants, concrete plants, grinding stations, port areas, power plants, etc.):
1. Assessment of Operational Dependency on Water Quality: Evaluates each site's level of dependency on "water flow regulation services," "water quality purification services," and "water supply" via ENCORE to identify operational dependencies and requirements related to water quality.
2. Assessment of Operational Impact on Water Quality: Assesses the extent of impacts during operational processes—including "freshwater use area," "seabed use area," "discharge of nutrient pollutants to water and soil," "discharge of toxic pollutants to water and soil," and "water consumption"—to evaluate potential risk levels to surrounding water quality and ecosystems.

Assessment of impacts on local stakeholders：
1. Client Satisfaction Survey

TCC conducts annual client satisfaction surveys. The 2025 survey covered cement, concrete, and mineral powder product customers across Taiwan, Mainland China, and Hong Kong, as well as cement, concrete, aggregate, and dry mortar customers of CIMPOR, and cement customers of OYAK Cement. The survey also incorporates "Sustainable Products" and "Quality and Safety," including indicators such as product carbon reduction levels, process water conservation, product safety traceability, and human health and safety. Through these interactions, TCC also engages with customers to discuss climate change and water resource management, gaining insights into their opinions and needs. 

2. Engage with Stakeholders

Communicate environmental policies,  requirements, and progress to all internal and external stakeholders. This is achieved through multiple channels, such as: Sustainability Newsletter, Supplier Conference Product Promotion Events and Conferences.

Assessment of future potential regulatory changes at a local level: We ensure compliance with all applicable local, regional, national, and international regulations related to water resources. Depending on the conditions of our operational sites, we take environmental actions that exceed legal standards.
