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 EMS factory, are 64,157.24 tonnes CO2e
Emissions from downstream product transportation and distribution1
Reduction Target : Reduce absolute product transport GHG emission 5% by 2025 from a 2021 base year.
The carbon emissions from laptops, desktop computers, all-in-one computers, and monitors product lines from shipping products from EMS factories to global destinations, are 71,891.27 tonnes CO2e
Emissions from employee commuting includes emissions
In 2023, the carbon emissions generated by commuting of employees at ASUS Headquarters were 5,989.06 tonnes CO2e
Business travels2
In 2023, the total carbon emissions from business travels of employees at ASUS Headquarters were 1,956.15 tonnes CO2e
1. ASUS refers to the method in "EPEAT-CCM-2023_4.1.3 Optional-Product transport carbon footprint and goal", and takes the emission coefficient verified by ISO 14064-1 for each transportation mode from well-to-wheel, to evaluate the weight and distance of the transported products to calculate the carbon emissions.
2. Business travels on land are not included in the calculation due to low significance on results.
Supply chain (Purchased goods and services)
The total carbon emissions from our key suppliers3 amount to 675,953.33 4 tonnes CO2e, with an emissions intensity of 86.26 tonnes CO2e per million USD, representing a reduction of approximately 26% in emissions intensity compared to the baseline year.
Capital goods
In 2023, ASUS’s procurement of capital goods resulted in carbon emissions of 4,068.53 tonnes CO2e.
Fuel and energy related activities
The total carbon emissions from upstream fuel and electricity procurement are 4,241.59 tonnes CO2e.
Operational waste generated
In 2023, ASUS' operational waste resulted in carbon emissions of 0.11 tonnes CO2e.
3. Key suppliers are makers of ICs, PCBs, mechanical components, cables, panels, HDDs, adapters, batteries, keyboards or assembly plants.
4. Total GHG emissions amount to 110,814.57 tonnes CO2e from Scope 1 and 565,138.76 tonnes CO2e from Scope 2, generated from energy use, including fuel, natural gas, and electricity usage. The total energy use is 1,433,732.98 MWh.
Emissions from the use stage of the product
ASUS has expanded its recognition of carbon emissions during the usage stage, with a total carbon emission of 1,069,442.93 tonnes CO2e and an emission intensity of 83.04 tonnes CO2e / Million USD. This represents a decrease of approximately 13.81% 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 7,767.24 tonnes CO2e.
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.
