Environmental Profit and Loss

Environmental Profit and Loss

2025 Sustainability Goals and Implemented Management Plans



For Greenhouse Gas: Ensure that our key suppliers achieve a 30% reduction in carbon emissions intensity rates by 2025



For Water resources: Help all suppliers receive ISO 14001 certification by 2025


Waste to Landfill

For Waste: Extend the Zero Waste to Landfill program from ASUS headquarters to key suppliers and set the waste diversion rate

The concept of an EP&L assessment is to map the impact of business activities on the environmental and social impact pathway and then monetize the environmental impact, such as the amount of agricultural ecological loss caused by greenhouse gas of climate change, and the impact of water pollution in reducing regional recreational value. The EP&L assessment facilitates the comparison of different environmental impacts and optimizes the quality of decision-making.

In 2018, ASUS and PwC collaborated on the first EP&L assessment project for laptops. According to the characteristics of the product manufacturing process, four environmental indicators —greenhouse gas, water resources, waste, and water pollution — were selected, and the total environmental impact of the product life cycle from extraction to component manufacturing, product assembly, and ASUS operations was calculated. ASUS became the first tech company in the world to publish an EP&L report. To fully understand the overall environmental impact of ASUS' operations and suppliers, we have added one category of major products in the data coverage each year to expand the scope to 90% of the products revenue.

We calculated the EP&L of the main representative revenue products of ASUS in 2022, including : laptops, desktop computers, mobile phones, motherboards and screens. The total environmental impact of greenhouse gases, water resources, waste, and water pollution was approximately US$625 million.



Energy resources required for business activities.

  • Examples: 8,000 tonnes of water, 100 million kWh electricity, etc.



How much environmental pollution emissions

  • Examples: 300 million tonnes of greenhouse gas, 2,000 kilograms of phosphorus pollutants, etc.



Changes to the environment

  • Examples: Global warming, eutrophication, etc.



Impact on society

  • Examples: Human health loss, ecosystem loss, etc.


Value of Impact

The Value lost due to the impact

  • Examples: Reduced Property, reduced entertainment value, etc.

Supplier Environmental Impact Survey

By analyzing the impact of environmental indicators, we identified water pollution as the most severe impact. It is followed by greenhouse gas, and the water resources accounted for the smallest share.


Based on the results, we identified the impact of hot spot in the product life cycle as the water pollution in the extraction of raw materials. We thus decided to invest management resources and formulated management strategies:

  • New suppliers must have ISO 14001 certification, and we will assist continuous trading suppliers who do not have it to obtain the ISO 14001 system.
  • Motherboard manufacturers are required to provide the annual wastewater test reports and make sure that it meets the environmental standard.

For greenhouse gases, we identify significant emission sources from the manufacturing of 9 key components to develop our management strategies:

  • 2022: Map manufacturing processes for key components and identify hotspots for emissions such as equipment with high energy consumption and processes with high carbon emissions
  • 2023: Map a carbon reduction pathway for key components based on emission hotspots and suppliers' carbon reduction capabilities
  • 2024 to 2025: Collaborate with suppliers on projects with low-carbon materials, process optimization, equipment energy efficiency improvement, and renewable energy to promote technology-based carbon reduction

Reduce Environmental Impact

By analyzing more than 100,000 data entries from environmental footprint surveys over the years, we identified significant sources of emission in the production of 9 catagories of key components, including display panels, motherboards, IC, cables, power supplies, mechanical components, keyboards, batteries, and hard drives, as well as OEMs for 4 categories of products in laptops, desktop computers, display monitors, and motherboards.

We referenced the "Greenhouse Gas and Water Security Questionnaire" of the Carbon Disclosure Project (CDP) to conduct an inventory of the 149 key suppliers. The results of the inventory in 2022 were as follows:

Greenhouse Gas

Water Resources

Hazardous Industrial Waste



29% of our suppliers use solar energy as renewable energy



62% of key suppliers have set greenhouse gas reduction targets



33% of key suppliers have ISO14064 third-party verification



29% of key suppliers have ISO50001 certification



58% of key suppliers have set water resource reduction targets



100% of key suppliers have contacted with quailed waste disposal providers



7% of key suppliers have zero waste certification
