Environmental Footprints of Supply Chain

ASUS identified that greenhouse gas and water footprints are the key risks in product production. In order to reduce the environmental impacts from them, ASUS has established supply chain environmental footprint management to survey greenhouse gas and water footprints to collect data and analyze the trends, providing reference for planning short, mid and long term reduction strategies.

Greenhouse Gases, Water, and Waste management

We follow the “Corporate Value Chain (Scope 3) Accounting and Report Standards" and "Carbon Disclosure Project - Water Disclosure” to conduct annual inventories with suppliers having continuous business relationships.


The key performances in 2019 were as follows:

  • Energy and Resource Emission and Usage

  • Proportion of suppliers with greenhouse gas emission and water usage reduction targets increase gradually

  • The proportion of suppliers using renewable energy increased from 16% in 2018 to 20% in 2019. The type of renewable energy was solar energy

  • Suppliers had commissioned qualified waste treatment plants to handle industrial waste, and the test data of wastewater was in compliance with legal requirements.

  • To fulfill the commitment in the Greenhouse Gas Reduction, we execute the following measures of management:
    • Provide a priority list of suppliers showing good environment practices, such as receiving ISO 50001 energy management system certification and using of renewable energy, to the procurement unit.
    • Set the greenhouse gases science based target (SBT) for 90% of suppliers by annual spend, and review the reduction performance year by year.
  • The manufacturing process of ASUS products is assembled by machinery, there is no process water, and no manufacturing waste water is discharged to surface water bodies.
  • All operational and manufacturing sites are not exposed to areas of high water stress classified by World Resources Institute (WRI).
