Environmental Performance

Since 2012, the introduction of ISO14064-1 GHG examination ensures data quality pass third-party verification every year.

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

Note1Wheeling” means that an electricity transmission and distribution corporation installs power grids through Taipower to transmit and distribute electricity for TWM.
Note2In 2020, TWM were generated total 588.93 MWh solar energy, due to some power stations have not yet completed the application for T-Rec, so TWM obtained 519 T-Rec in 2020, which were declared to Data center.
