GHG emissions are a major cause of the climate emergency, and corporate GHG management is one of the main concerns of stakeholders. Since 2021, the Company has established a mechanism of GHG inventory standards according to ISO 14064 and the Operation Directions for GHG Validation of the Environmental Protection Administration, Executive Yuan. We conduct regular GHG inventories from all company facilities each year and underwent verification by a third-party verification body (Metal Industries Research& Development Centre) in 2022 to fully understand the current status of GHG usage as a way of verifying the effectiveness of reduction efforts. Operating controls are used as the organizational inventory boundary, the Company inventoried all manufacturing processes and facilities managed by all factories (Taipei Head Office, Hsinchu Factory, Xinying Factory, Kaohsiung Factory, and Container Terminal No. 7). The greenhouse gases emitted by the Company include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and hydrofluorocarbons (HFCs). No ozone-depleting substances (ODS) were used in the factories.
