Environmental Performance

TWM have introduced the ISO14064-1 greenhouse gas inventory since 2012 and have passed third-party verification each year to ensure data quality. The TWM business is expanded to telecommunications and media industries. The main source of emissions is the electricity used for operations (98%), and the electricity consumption in base station rooms is the main source. Other emission sources are refrigerants, fire extinguishers, septic tanks, and official vehicles.
