Greenhouse Gas Management

In order to measure GHG emissions more accurately, SYSTEX conducts GHG Inventory according to the guidelines of “ISO 14064-1: 2018” and collects the inventory results to plan for future improvement plans. For the inventory, SYSTEX has set up a “GHG Inventory Committee” to prepare audit reports and to conduct data audit according to the “Internal Audit Management Procedures”, and then entrusted an independent 3-party to conduct external audit, ensuring its correctness and completeness. The boundary of GHG inventory is the headquarters building.

In 2021, the total GHG emissions of the SYSTEX headquarters building was 3,353.6 tonCO₂e, of which the electricity consumption accounted for the highest proportion of emissions, reaching 82.88%.

SYSTEX conducts GHG verification every year according to the “Internal Audit Management Procedures” with the operation management unit as the internal auditor, and then entrusts a 3-party organization to conduct sampling verification. Therefore, the GHG inventory results are used to evaluate GHG emission reduction and improvement measures.

• Category 1: Direct GHG emissions

SYSTEX counts emission sources in the headquarters building, including the sources of stationary combustion, mobile combustion and fugitive.

• Category 2 – 6: Indirect GHG emissions

All emission sources of category 2 – 6 have been discussed by the “GHG Inventory Committee” according to the guidelines of “ISO 14064-1: 2018”, and should be defined as

significant emissions with a score over 30.

• Emission Factor

The emission factors are based on the latest data published by the IPCC, EPA or relevant authorities.
