GHG Inventory

Climate warming actions have become an important concern for the world. Ardentec conducts GHG inventories of all the Group’ s operational sites and fabs in accordance with inventory guidance, such as ISO 14064-1:2018 and GHG inventory protocols. According to the results of the inventory, the main source of emissions is indirect carbon emissions of purchased electricity derivative scope 2 for 24-hour test machine operation. Direct emission scope 1 is fugitive emission of HFCs from refrigerant of air conditioning system and a small amount of PFCs gas (CF4) used in the test machine, and CO2 and CH4 and N2O emissions caused by the use of gas and diesel vehicles. The data-based indicators from the inventory results are used to understand the impact and influence of operational activities on the environment as the basis of planning GHG reduction strategies.


GHG Reduction

Ardentec’s GHG scope 1 is mostly CO2 emissions from fixed sources with a very small amount of PFCs that are mixtures for refrigerant filling, accounting for about 2% of the total emissions from scope 1 and 2.


Ardentec headquarters’ GHG scope 1 and scope 2 reduction method is mainly based on the use of renewable energy to reduce the emission of scope 2, together with carbon rights procurement to reduce GHG emissions ratio.


Headquarters’ reduction goal:



 Reduction Goal








100% carbon neutrality



Carbon Reduction and Renewable Energy Targets Reached in 2022

2022 goals and achievements


Achievements in carbon reduction

In 2022, the headquarters have been implement energy-saving measures, use renewable energy and purchase 14,500 tons of carbon rights, reducing category 1 and category 2 emissions by 5.9% compared with 2020, achieving the goal of reducing 4% in 2022 compared to 2020.

Renewable energy achievement

Climate change and greenhouse gas reduction continue to receive high attention from the international community, and the use of low-carbon energy has become an indispensable part of the industry. The headquarters started using renewable energy in 2021, expanded to subsidiaries in 2022.


  • Use of renewable energy and purchase REC:


The whole group usage of 6,850 thousand kWh of renewable energy or purchase REC, which is 3.2% of the total electricity consumption in 2022, achieving the goal of 3%.



  • Solar power generation:


The headquarters were completed construction of solar power generation facilities on the top floors of TingShin site in 2022. The total power generated by the solar power generation facilities were 503,000
kWh. In 2023, the headquarters and its subsidiaries will continue to build 980kW solar power generation facilities to increase the energy of solar power generation.



Target for 2023

Carbon Footprint Management
