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 2021and in 2022 were 197,445.978 tons CO2e / year and 173,929.290 tons CO2e / year, respectively. That in 2022 was 12% lower than that in 2021. We 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. |
Verification not carried out. |

Note:
- The above data are rounded to the third decimal place.
- In April 2023, the greenhouse gas inventory inspection has been completed and verified by a third-party, and its verification certificate is expected to be obtained in June 2023.
- Greenhouse gas emission factors are based on "2006 IPCC Guidelines for National Greenhouse Gas Inventories ", "Electricity Carbon Emission Factor for 2020" by the Bureau of Energy, Ministry of Economic Affairs, Taiwan, and "Greenhouse Gas Emissions Factors Management Table Version 6.0.4" by the Environmental Protection Administration, Executive Yuan, Taiwan, "Baseline Emission Factors for Regional Power Grids in China " and "China Energy Statistical Yearbook 2016".
- The Global Warming Potential (GWP) values for various greenhouse gases in 2021 were based on the IPCC's fifth assessment report in 2013 (GWP 100-year). The GWP values for various greenhouse gases in 2022 were based on the IPCC's sixth assessment report in 2013 (GWP 100-year).
- The greenhouse gas include CO2, CH4, N2O, HFCs, PFCs, SF6 and NF3.
- The Company’s inventory of the greenhouse gas emissions is based on the emissions in the production of printed circuit boards, which is characteristic of the PCB industry where the Company is.
