Environmental Performance

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

Since 2012 when TWM adopted the ISO14064-1 standard, GHG inventories have undergone third-party verification annually to ensure the quality of the data. The main source of emissions is electricity (98%); the remaining sources include company vehicles, generators, refrigerants, fire extinguishers, and septic tanks.

Note 1Used the 2021 emissions factor for electricity issued by the Bureau of Energy under the Ministry of Economic Affairs to calculate Scope 2 carbon emissions for 2022

Note 2According to the GHG Protocol Scope 2 Guidance, reporting of Scope 2 emissions related to the purchase of renewable energy certificates has been required to be done two ways since 2018: one based on the location-based method, and one based on the market-based method.
