Sustainable Water Management

The Company is conscious of the problems and risks of water scarcity. Understanding that water is a fundamental resource essential to life and business operations, the Company implemented efficient management of water resources throughout the supply chain with the following projects.

In order to prevent water scarcity in areas with communities and impact to processes in business operations, the Company has implemented efficient management of water through the risk assessment on water stress using the Aqueduct tool from the World Resource Institute in all areas with business operations. The results of the risk assessment showed that 17.26% of operation areas are in areas with Extremely High risk and 17.44% are located in areas with High risk as shown in the image.

Water Stress

In response, the Company has planned to mitigate these risks through the appointment of the Water Management Committee tasked with establishing a water consumption reduction plan and implementing projects to support the reduction of water consumption as appropriate.

Additionally, the Company has conducted an evaluation on the risk of water scarcity for 129 Critical Tier 1 Suppliers using the Aqueduct tool. The result of the assessment revealed that 39 Critical Tier 1 Suppliers were in areas with Extremely High and High risks. In sequence to the assessment, the Company has continuously monitored and reassessed the risks to these suppliers.

Concurrently, the Company has partnered with its suppliers to mitigate water-related risks through suitable and efficient means according to the law, such as collaborating with relevant agencies and communities to establish plans for mitigating risks related to water and reusing water. The collaboration extended to the restoration and development of water sources in communities to prevent any conflict with the communities. At present, the project has gained cooperation from Critical Tier 1 suppliers and 100% of the suppliers have continuously implemented projects to mitigate the risks and impact related to water.

Water Conservation Project

The Company continuously executed the Zero Wastewater Discharge project which raised awareness of the value of water resources and efficient water management. Moreover, the scope of the project encompassed the management of wastewater for reuse to reduce wastewater discharge into the public. The various projects that have been executed are as follow.
