Environmental Performance

Since the introduction of ISO14064-1 greenhouse gas inventory in 2012, third-party verification has been adopted to ensure data quality each year. The new version of ISO 14064-1: 2018 was completed In 2019.

The main emission source is electricity (97%), the remaining sources include company vehicles, generators, refrigerants, fire extinguishers, septic tanks, etc.

Project 2017 2018Note 1 2019
Scope1 (Direct Emissions) (ton-CO2e) 4,846.90 4940.26 6,327.10
Scope 2 (Indirect Emissions) (ton-CO2e) - Location BasedNote 2 247,829.57 229,672.62 229,792.43
Scope 2 (Indirect Emissions) (ton-CO2e) - Market BasedNote 2 - 226,973.51 229,611.74
Total Carbon Emissions (Scope1+2) (ton-CO2e) - Location BasedNote 2 252,676.47 234,612.88 236,119.53
Total Carbon Emissions (Scope 1+2) (ton-CO2e) - Market BasedNote 2 - 231,913.77 235,938.84
Emission intensityNote 3 = total carbon emissions geographically / combined revenue (ton-CO2e / NTD million) 3.02 3.07 3.21
Note 1Scope 2 carbon emissions for 2018 was retrospectively revised according to the 2018 Electricity Factor announced by the Energy Bureau of the Ministry of Economic Affairs.
Note 2From 2018, according to the GHG Protocol Scope 2 Guidance, the certificate of renewable energy purchase for category 2 should be calculated according to "Location Based" and "Market Based".
Note 3Revenue from momo was deducted from the consolidated revenue in 2019, and the emission intensity values for 2017 and 2018 was retroactively revised.

GHG inventory (scope 3)

Note 1 No intermediate products are processed and remanufactured, so NO.10 is not applicable. Since they have been included in the scope 1 and 2 GHG greenhouse gas, NO.15 is not applicable.
Note 2Due to changes in the purchase quantity and amount of mobile phone products, as well as EEIO coefficient update in 2018, a total of 4 items including NO.1, NO.2, NO.8, and NO.9 were retrospectively revised to facilitate the SBT annual target tracking and inspection.
