Inventory of Greenhouse Gas Emissions
Inventory of Greenhouse Gas Emissions
Inventory of greenhouse gas emissions
The Company regularly checks greenhouse gas emission in accordance with ISO 14064-1. The boundary range includes plants in Taiwan and in China, so as to grasp the overall greenhouse gas emission status and to review and set our yearly goals. Our results of the greenhouse gas inventory in 2021, in 2022 and in 2023 were 197,445.978 tons CO2e / year, 173,929.290 tons CO2e / year and 167,093.377 tons CO2e / year, respectively. That in 2022 was 12% lower than that in 2021 and that in 2023 was 15% lower than that in 2022. In response to the requirements of the government and customers, Scope 3 will be included in the scope of inventory of greenhouse gas emissions in 2023. The results of the Scope 3 inventory are 83,651.663 tons CO2e/year, and the total emissions in 2023 will be 250,745.040 tons CO2e/year. We will continue to implement carbon reduction measures to meet the emission targets expected by our customers and the government.
The scope of inventory is as follows:
Category |
Scope |
Execution Method |
Scope 1 Direct greenhouse gas emission |
1. Direct emissions from stationary combustion, such as electricity generators, boilers 2. Direct emissions from mobile combustion, such as official vehicles, stackers, etc., which consume petrochemical raw materials to produce greenhouse gases. 3. Direct fugitive emissions from the release. |
Qualitative and quantitative examination. |
Scope 2 Energy indirect greenhouse gas emission |
Imported electricity |
Qualitative and quantitative inspections. |
Scope 3 Other indirect greenhouse gas emission |
Employees’ commuting, outsourcing, such as: waste removal, air/sea/land transportation contractors, etc. |
No inventory was carried out in 2021, and its inventory begun in 2022. |
