The policy regulates ASEH's management of environmental aspects with business partners and stakeholders, including suppliers, contractors, customers, joint venture partners, and the community. It is also used as a guideline for due diligence in merger and acquisition transactions.

Managing water resources is a top priority at ASEH. We strive to improve and optimize water usage efficiently. With ISO 46001 Water Efficiency Management Systems, we identify risks, opportunities, and develop water-saving measures.

ASE Technology Holding will conduct a survey on the risks and opportunities related to climate change and water through questionnaires distributed to key department heads.

At ASEH, we prioritize managing our water resources. We aim to improve and optimize water usage by adopting ISO 46001 Water Efficiency Management Systems. This helps us identify risks, opportunities, and develop water-saving measures, risk mitigation strategies, and action plans.

ASEH implements source reduction measures, uses eco-friendly materials, and promotes ISO14001 certification and environmental data collection. Facilities failing to meet targets must propose improvement plans.

ASEH promotes biodiversity and responsible environmental activities. We are committed to meeting NNL and achieving NPI on biodiversity. We collaborate across our value chain to achieve the UN Convention on Biological Diversity’s vision of a harmonious world with nature.
