Inventory methods include ISO 14064-1:2018, the GHG Protocol - An Enterprise Accounting and Reporting Standard, GHG Inventory Registry Operation Guidelines. GWP values are based on 2021 IPCC AR6. Emissions factors are based on Environmental Protection Administration's GHG Emission Factor Management Table v. 6.0.4. 5. Carbon emissions from the second headquarters location have been included since 2022. 6. The GHG emissions have been verified by an independent third party (SGS Taiwan Ltd.). 7. Scope 1 & 2 are named Category 1 & 2 in ISO14064-1:2018. 8. Greenhouse gas include CO2、CH4、N2O、HFCs、PFCs、SF6 and NF3 9. No biogenic greenhouse gas emissions were generated from Scope 1 and Scope 2 in 2025. 10. The operational control approach is adopted for the quantification method. |

Note: 1. Scope 3 emissions inventory is done based on the "Corporate Value Chain (Scope 3) Accounting and Reporting Standard," developed by WRI & WBCSD in 2011. 2. Beginning from 2022, CTCI will carry out Scope 3 GHG inventory, coverage is 100%. The emissions data 2021 is based on Scope 3 screening results. 3. The foreign carbon emission coefficients used in EEIO are sourced from international databases: https://www.exiobase.eu/、https://websites.umich.edu/~mingxu/ceeio.html 4. The carbon emission coefficients for goods are from the carbon footprint database of the Ministry of Environment. 5. According to ISO 14064-1:2018, indirect greenhouse gas emissions require significant identification. Categories 1, 3, 5 (general waste), and 8 have been verified based on the identification results, and the data has been verified by the third party. |
