▍Energy Management
In 2023, the Company’s total energy consumption is approximately 498.33×10³ GJ, of which purchased electricity accounts for 55%. Compared with 2022 (626.93×10³ GJ), the total energy consumption was reduced by 128.60×10³GJ (21%). This was mainly due to the replacement of outdated equipment (such as chillers, air compressors, ice makers) and the implementation of various energy-saving improvement measures, with an investment of around NTD 30 million. As a result, the consumption of electricity, diesel, natural gas and steam decreased by 17%, 12%, 21% and 30%, respectively, compared to the previous year. Overall energy intensity also decreased by 4% (68 and 72 GJ/million NTD in production value in 2023 and 2022, respectively). Everlight Plant II obtained self-generated solar power usage on March 1st, 2023, with an installation cost of 21.4 million NTD. By the end of 2023, our utilization rate (renewable energy/total energy) is 0.26%, with an estimated annual generation of 450,000 kWh, reducing carbon emissions by approximately 229 tCO2e.
Everlight planned to implement ISO 50001 in Plant I, II, III in 2022 and achieved certification in 2023. Some unplanned plants also sent seed members to participate in this study to gradually expanded to the subsidiaries. This is expected to help identify areas for improvement related to energy supply risks, continuously enhance overall performance, reduce energy consumption and costs. The Company also plans to obtain ISO 50001 certification for Everlight Plant IV and Trend Tone Imaging in 2024.
▍Historical Greenhouse Gas Emission Intensity Information
With the implementation of various energy consumption improvement measures, the greenhouse gas emission intensity in 2023 was 8.55, rounded to 8.6 tCO2e/million NTD in production value. Although there was no significant decrease compared to 2022 (8.6 tCO2e per million NTD in production value), it still met the 2023 target (8.7 tCO2e/million NTD in production value). Thanks to the efforts of all employees, the total greenhouse gas emissions for the year were 62,318 tCO2e, a decrease of approximately 17% from 2022 (75,286 tCO2e). Overall, we continue to work diligently according to the Group’s carbon reduction plan, including replacing high-energy-consuming equipment and continuously improving processes.

▍Energy Saving and Carbon Reduction Results
★ Special Report
Through continuous efforts and innovation, we have made significant progress in reducing greenhouse gas emissions and improving energy management efficiency. We have not only achieved excellent results in reducing energy consumption and greenhouse gas emissions, but also improved overall operational efficiency and made positive contributions to achieving our sustainable development goals.
Climate change and issues posed by climate policy, emerging technologies and carbon pricing are all bringing changes and impacts to operations. Everlight has set a 25% emission reduction target by 2030 with reference to the 2030 emission reduction target proposed by the National Development Council at the end of 2022. We also conduct climate change-related financial disclosures (TCFD) and promote various carbon reduction plans and initiatives to support the 2050 net-zero carbon emission target.
Firstly, we optimized processes and equipment, and implemented ISO 50001 energy management system to more effectively monitor and control energy consumption. We also followed the ISO 14064-1 standards and continuously promoted greenhouse gas reduction measures to reduce emissions. Additionally, we actively adopted energy-saving equipments, systematized energy management, and invested in renewable energy infrastructure to reduce dependence on traditional energy sources.
Starting in 2021, we promoted energy-saving and carbon reduction projects, including the replacement of outdated equipment (such as chillers, air compressors and ice makers) and the implementation of various energy-saving measures and process and equipment improvements. The target of these energy-saving and carbon reduction measures is to save at least 1% of electricity annually【Note 1】. In 2023, we saved a total of 1,231,000 kWh of electricity, reducing carbon emissions by approximately 609 tCO2e, which is equivalent to the annual carbon absorption of 50,750 trees【Note 2】. This equates to approximately 4,435 GJ of energy saved, a total electricity savings of 1.5%.
Note 1:
The calculation of electricity savings and carbon reduction in 2023 is based on the latest “2022 Electricity Carbon Emission Factor = 0.495 kg CO2e/kWh” and the relevant energy coefficient values from the 2022 Energy Statistics Handbook announced by Energy Administration, Ministry of Economic Affairs.
Note 2:
According to the article “Contribution of trees to the environment” published by Environmental Quality Protection Foundation,
Note 1:
Heat Value Saved (kcal) = [Electricity Saved (thousand kWh) × Electricity Heat Value (8.6 × 10⁵ kcal/thousand kWh)]
Note 2:
Carbon Emissions Saved (tCO2e) = [Electricity Saved (thousand kWh)×Latest Annual Electricity Carbon Emission Factor (0.495 tCO2e/thousand kWh)].
Note 3:
Energy Saved (GJ) = [Heat Value Saved (kcal)×Heat Value Coefficient (4.187 × 10³ joules (J)/kcal)]÷109
Note 4:
All statistics in the table are rounded to the nearest integer.
Note 5:
The scope of the above carbon emission reduction performance conversion is Scope 2.
Historical Ozone-Depleting Substances (ODS) Emission Information
Everlight has gradually reduced the use of ozone-depleting substances (ODS) refrigerants over the years
Note 1:
The ODP value of R22 refrigerant is 0.055 (according to the Montreal Protocol), and the ODP value of CFC-11 is 1. The usage of R22 refrigerant is converted to CFC-11 equivalent (tons) as shown in the above data.
Note 2:
The ODS emissions are calculated based on the Ozone Depletion Potential (ODP) coefficients listed in the annex of the Montreal Protocol.
▍Greenhouse Gas Management Performance
Regarding greenhouse gas inventory and energy use management, Everlight has established three management indicators: (1) Power Saving Percentage, (2) Greenhouse Gas Emission Intensity (tCO2e/million NTD in production value), and (3) Energy Intensity (GJ/million NTD in production value). In 2023, Everlight Group continued to demonstrate progress towards the Net-Zero mid-term target set for 2025, as declared in 2022.
Historical Management Indicators and Mid-term Target Achievement
Note 1:
In 2022, external consultants assisted in planning energy saving and carbon reduction, and adjustments were made to the short, medium, and long-term reduction targets for energy intensity and greenhouse gas emission intensity.
Note 2:
The reduction in production capacity due to the COVID-19 pandemic and the increase in the production of some energy-intensive products are the main reasons.
Note 3:
The verification method for refrigerant emissions in 2022 was based on equipment refrigerant leakage, differing from the previous selfinventory method that used refrigerant purchase and replenishment amounts. Therefore, the inventory was standardized to the verified equipment refrigerant leakage method. Although the revised historical carbon emission data differ slightly from previously disclosed figures, they do not affect the previously set medium and long-term targets.
Note 4:
Considering the significant differences in product combination/process characteristics over the past two years compared to 2021, the medium and long-term targets for energy intensity have been adjusted .
