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.ASUS identified that greenhouse gas and water footprints are the key risks in product production.

Greenhouse Gas Management

ASUS conducts greenhouse gas inventory on suppliers and OEMs with significant greenhouse gas emission according to "Corporate Value Chain (Criterion 3) Accounting and Report Standards". The inventory parameters were as follows:

Scope of Inventory:

  • Duration of data collection: January to December 2017
  • Business boundary: Scope I and II
  • Data allocation: based the proportion of ASUS products in total shipment
  • Global warming potential (GWP) emission coefficient: 2007 IPCC AR4 100-yr

 

Data Analysis:

In 2017, greenhouse gas inventory was done for 160 component suppliers and OEM providers, and the results were showed below:

  • Total emission volume of Scope 1 and 2: Scope 1 was 4% when Scope 2 was 96%. The primary source of Scope 2 indirect emission was the procured electricity.
  • Greenhouse gas verification: 37% implemented external verification.
  • Greenhouse gas reduction management: 50% of them had established GHG reduction programs and targets
  • Renewable energy management: 14% of them had used renewable energy, 8% of them had planned to introduce the renewable energy.

The analysis result will be the basis for developing the short-term and mid-term management strategies of greenhouse gas:

  1. Request the OEM providers and suppliers with the highest greenhouse gas emissions ratio to set energy saving plans and targets.
  2. Encourage OEM providers and suppliers to introduce renewable energy, and for those who have been using renewable energy should receive more weighting for QBR.

Water Resource Management

Water management is another concerned issue of environmental footprint. The consumption of water resources are mainly from component manufacturing process and product assembly process in supply chain. The parameters of water resource inventory were consistent with the greenhouse gas inventory.

Data Analysis:

In 2017, water resource inventory was done for 160 component suppliers and OEM providers, and the results were showed below:

  • Risk identification: 86% of them performed the risk identification. 96% of them identified no risk when 4% (4) of them did.
  • Equipment invested for water treatment: 26% of them had deployed water treatment equipment.
  • Reduction plan of water resource: 62% had setup reduction plan and target to decrease the use of water.

The analysis result will be the basis for developing the short-term and mid-term management strategies of water resource:

  1. Request the OEM providers and suppliers with the water usage ratio to set water saving plans and targets.
  2. Monitor the risk on delivery for those who had identified water risks.
  3. In line with the environmental profit and loss project, the wastewater pollution survey would be conducted next year.
