Greenhouse Gas Inventory

ASUS has implemented greenhouse gas inventory since 2007, and the scope includes direct greenhouse gas emissions, indirect greenhouse gas emissions from imported energy, indirect greenhouse gas emissions from products used by organization (Purchased goods and services, supply chain), indirect greenhouse gas emissions associated with the use of products from the organization (Use of sold products), indirect greenhouse gas emissions from transportation (Business travel, Downstream transportation and distribution). ASUS also completed third-party certification in accordance with ISO14064-1:2018. The data from the inventory in 2021 showed that ASUS' total carbon emissions amounted to 1,477,368 tons CO2e.

Category 1: Direct greenhouse gas emissions

ASUS does not have an assembly plant, and the main direct emission sources are the use of firefighting equipment, backup generators and office vehicles.

Type of Source Type of Energy Activity Data Carbon Emission(ton CO2e) Total Carbon Emission(ton CO2e)
Stationary Source (Emergency generator) Diesel 7,500 L 19.61 93.98
(Boiler) Natural gas 20,874 M3 45.69
Mobile Source (Office vehicle) Diesel 823 L 2.18
(Office vehicle) Gasoline 11,253 L 26.50

Emission intensity: 0.0052 tons CO2e/USD million

Category 2: Indirect greenhouse gas emissions from imported energy

According to the list in the financial report, after excluding companies that ASUS does not have control rights, the total carbon emissions fell by 15.8% from the previous year.

Taiwan China Overseas Total
Electricity Usage (MWH) 19,188 7,984 5,425 32,597
Carbon Emission(ton CO2e) 9,767 4,431 2,963 17,161

Emission intensity: 0.9430 tons CO2e/USD million

Category 3: Indirect greenhouse gas emissions from transportation

Reduction Goal: Reduce 10% of carbon emissions from downstream transportation of products per year

Business travel and downstream transportation of products were material.

  • Business Travel
    The total carbon emissions from employees' business travel in 2021 amounted to 260 tons CO2e. Due to the impact of the COVID-19 pandemic, the total carbon emissions fell by 57% from the previous year. (Domestic business travel and foreign business travel on land were not included in the calculation due to low significance)
  • Downstream Transportation of Products
    The carbon emissions of notebook computer, desktop computer, all-in-one PC, and monitor product lines shipped from factories to global markets amounted 15,363 tons CO2e.

Reduction Progress: Compared to 2020, reduction of carbon emissions from downstream transportation of products reached 28.1%

Category 4: Indirect greenhouse gas emissions from products used by organization (Purchased goods and services)

The total carbon emissions of key suppliers from nine types amounted to 1,076,291 tons CO2e, and the emission intensity was 126.41 tons CO2e/USD million.

Category 5: Indirect greenhouse gas emissions associated with the use of products from the organization (Use of sold products)

The total carbon emissions from the use of sold products in countries/regions that account for 90% of global revenue amounted to 368,198 tons CO2e, and the emission intensity was 27.77 tons CO2e/USD million.
