GHG Inventory

Climate change action has become a significant global focus. Ardentec, in accordance with ISO 14064-1:2018 and the Greenhouse Gas Protocol, conducts greenhouse gas inventories at all operational sites and plants within the Group. The data from these inventories are used to assess the environmental impact and effects of operational activities and to formulate greenhouse gas reduction strategies. According to the inventory results, the primary source of emissions is the indirect carbon emissions (Category 2) derived from the purchased electricity used for the operation of 24-hour testing machines. Direct emissions (Category 1) are caused by refrigerant leakage of HFCs from air conditioning systems, a small amount of PFCs (CF4) from test machines, and CO2, CH4, and N2O emissions from gasoline and diesel vehicles. Ardentec does not use ozone-depleting substances in its processes.

Greenhouse Gas Reduction

 

Ardentec's Category 1 greenhouse gas emissions primarily consist of fixed-source CO2 and HFCs refrigerant filling mixtures, accounting for approximately 3.9% of the total emissions from Categories 1 and 2. In 2024, the headquarters and subsidiaries reduced 10,702 metric tons of CO2 equivalent through the use of renewable energy and the procurement of renewable energy certificates, along with the purchase of 15,705 tons of carbon credits. This resulted in a 13.3% reduction in emissions from Categories 1 and 2 compared to the base year of 2020. Ardentec's greenhouse gas reduction targets for Categories 1 and 2 are as follows: 10% reduction by 2025, 20% by 2030, 60% by 2040, and achieving carbon neutrality by 2050.


The primary reduction pathway is to reduce Category 2 emissions through the use of renewable energy. If, due to market factors, renewable energy cannot be successfully acquired in the future, the purchase of renewable energy certificates will be used as an alternative.

 

 

 

 

 

Energy Use

 

Amid the global trend toward low-carbon energy development, governments and corporations worldwide are increasingly investing in carbon reduction and renewable energy transitions. According to the International Energy Agency (IEA), although oil demand continues to grow, the global energy market is accelerating its shift toward low-carbon energy sources. In response to this trend, Ardentec is actively engaging in the global low-carbon energy transition by implementing a series of energy management and carbon reduction measures.

 

In the 2024 energy consumption structure, electricity accounted for 99.7% of the total energy consumption. Non-renewable electricity consumption totaled 702,070 GJ, followed by renewable electricity consumption at 81,148 GJ, and gasoline consumption at 1,364 GJ, contributing to a total energy consumption of 785,715 GJ for the reporting year.

 

As part of its concrete actions, Ardentec has continued to expand its deployment of renewable energy. Since 2021, the Company has been procuring renewable energy certificates. With the expansion of solar power generation facilities and increased renewable energy procurement, the share of renewable energy is expected to rise further in the coming years. In 2024, the combined use of renewable electricity and renewable energy certificates totaled 22.54 million kWh, accounting for 10.4% of total electricity consumption, successfully achieving the 7% target. Through these proactive measures, Ardentec not only aligns with the global low-carbon energy transition trend but also demonstrates its strong commitment to sustainable operations and environmental stewardship, contributing to global carbon reduction and energy transition efforts.

    The headquarters and subsidiaries have set plans to establish solar power generation facilities at their respective plants. In 2022, the headquarters completed the installation of a 499 kW facility. In 2023, the headquarters and subsidiaries completed solar power generation facilities totaling 980 kW. In 2024, the headquarters generated a total of 900,000 kWh, which was sold to Taiwan Power Company, while the subsidiaries generated a total of 967,000 kWh for self-consumption.
