Emissions from upstream product transportation and distribution
The carbon emissions from laptops, desktop computers, all-in-one computers, and monitors product lines from the parts factory to the HUB, and finally to the OEM factory, are 63,961.95 tonnes CO2e
Emissions from downstream product transportation and distribution
The carbon emissions from laptops, desktop computers, all-in-one computers, and monitors product lines from the parts factory to the HUB, and finally to the OEM factory, are 58,345.42 tonnes CO2e
Emissions from employee commuting includes emissions
In 2022, the carbon emissions generated by commuting of employees at ASUS Taiwan were 6,308.83 tonnes CO2e
Business travels
In 2022 , the total carbon emissions from business travels5 of employees at ASUS Taiwan were 1,361.32 tonnes CO2e
Supply chain (Purchased goods and services)
The total carbon emissions from our key suppliers are 1,062,862.96 tonnes CO2e with emissions intensity of 88.34 tonnes CO2e/ Million USD which is about 30% lower than last year's emission intensity
Fuel and energy related activities
The total carbon emissions from upstream fuel and electricity procurement are 3,672.07 tonnes CO2e
Emissions from the use stage of the product
ASUS has expanded its recognition of carbon emissions during the usage stage, with a total carbon emissions of 1,296,320.23 tonnes CO2e and an emission intensity of 97.03 tonnes CO2e / Million USD (a one-year emission intensity of 23.83 tonnes CO2e / Million USD), based on the 4-year service life of the products sold. This represents a decrease of approximately 12.64% in emission intensity compared to last year.
Emissions from end of life stage of the product
The final disposal of products sold globally includes the transportation stage from recycling stations to treatment plants, as well as the disposal stage. Total carbon emissions are 9,262.36 tonnes of carbon dioxide equivalent
In practice, the methods for greenhouse gas inventory can be classi fied into two approaches: ISO 14064-1 and GHG Protocol. ISO 14064-1 emphasizes the disclosure of greenhouse gas inventory information, It is suggested that corporate should identify the emission sources which is material to operation and conduct GHG inventory focusing on these catogories while GHG Protocol focuses on the comprehensiveness of the greenhouse gas inventory calculation scope.
