Greenhouse Gas Management
In order to measure GHG emissions more accurately, SYSTEX has introduced GHG Inventory since 2021 and conducts GHG Inventory every year according to the guidelines of “ISO 14064-1: 2018”, to formulate improvement plans accordingly. 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 third-party to conduct external audit, ensuring its correctness and completeness. The boundary of GHG inventory is the headquarters building.
In 2022, the total market-based GHG emissions of the SYSTEX headquarters building was 3,347.446 tCO2e, of which the electricity consumption accounted for the highest proportion of emissions, reaching 82.54%.
SYSTEX conducts Headquarters GHG inventory of category 1-6, using the parameters released by the IPCC, EPA or relevant authorities. The inventory covers:
- 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.
Category 2 emissions are generated by imported energy.
Category 3-4 emissions are calculated from business travels, indirect carbon footprint of electricity and disposal of general waste.
- Emission Factor
The emission factors are based on the latest data published by the IPCC, EPA or relevant authorities.

Greenhouse Gas Management Performance
Through the ISO 14064-1 GHG inventory, SYSTEX found that purchased electricity produced the highest proportion of emissions. Therefore, in addition to implementing various environmental and energy management measures, SYSTEX purchases and rents equipment with environmentally-friendly labels, replaces power-consuming equipment every year, regularly checks pipelines, and sets the office temperature to no less than 26°C, thereby reducing electricity consumption and environmental load. Furthermore, SYSTEX also supports the development of renewable energy. In addition to purchasing T-REC every year, SYSTEX plans a “Power Wheeling Contract” program in 2022 and is expected to use green electricity in 2023.
3-year GHG Emissions of Category 1-2 [Scope: SYSTEX headquarters building]
In 2022, due to the increase in the business scale, SYSTEX increased electricity consumption, which also increased the category 2 emissions compared to the previous year. However, the GHG emissions per unit revenue in the past 3 years has a continuous downward trend, showing that SYSTEX earns more revenue while using each kWh of electricity, thereby utilizing electricity more efficiently. Considering the increased emissions caused by larger business scale, SYSTEX signed a green-energy contract in 2022 to mitigate the impact of power usage.
