Climate Change and Energy Management

The Company supports the carbon reduction goals of the Paris Agreement. In response to climate change and the implementation of green operations, since 2011, the Company has been conducting an annual GHG emissions inventory through the Ministry of Environment of the Executive Yuan with the Greenhouse Gas Protocol tool provided by the Intergovernmental Panel on Climate Change (IPCC) of the United Nations. The Company also passed the verification against the ISO 14064-1:2018 standards.

Greenhouse Gas Management

In 2023, the Company's direct emissions (Category 1) and indirect energy emissions (Category 2) totaled 15,676.301 metric tons of CO2e, an increase of 334 metric tons of CO2e compared with 2022. The Company has no manufacturing operations, so the main emissions come from purchased electricity. Our emissions intensity in 2023 increased to 0.325 metric tons of CO2e per million dollars of revenue, up 27.45% from 2022, mainly due to decreased operating revenue as a result of the market's demand adjustment. Every year the Company launches different energy-conservation programs and purchases renewable energy, constantly heading toward the goal of net zero emissions.

Statistics of Energy Consumption

To review and improve our energy usage efficiency, the Company inventories our energy consumption amount every year. In 2023, the Company's total energy consumption was 116,305.30 GJ, and our energy use intensity was 2.412 GJ per million dollars of revenue. Energy intensity soared by 33.55% from the previous year, mainly due to the reduced operating revenue due to the market's correction of demand.

Since 2021, the Company has been purchasing renewable energy (electricity generated from wind power). By 2023, the renewable energy usage accounted for 3.11% of total electricity consumption. In order to carry out our energy transformation in a steady pace and to reduce the GHG emissions during operations, we aim to increase such percentage to 10% by 2025, and 20% by 2030.

The Company purchases a certain proportion of renewable energy based on monthly electricity consumption. Due to Taipower's settlement date, only data from January to November 2023 is currently available. The company reduced 375.9 metric tons of CO2 emissions in 2023 due to the use of renewable energy.

In addition, the company obtained a total of 613 T-REC certificates from January to October 2023 (the T-REC certificate operation period is two months, and it will take until mid-February 2024 to fully obtain the number of certificates for 2023).
