Energy Management
In 2023, the primary energy sources used were natural gas and non-renewable electricity purchased from external power companies, followed by diesel. The total energy consumption in 2023 was 6.1462 million cubic meters of natural gas, 63.3785 million kilowatt-hours of electricity (including both non-renewable and renewable electricity), 13,400 liters of gasoline, and 1,800 liters of diesel. Converted to energy units, this totaled 470,280.43 GJ (gigajoules), a decrease of 45,179.30 GJ (8.76%) compared to 2022. When calculated per revenue, the total energy consumption in 2023 had an energy consumption intensity (energy consumption per million NTD revenue) of 27.46 GJ per million NTD, a reduction of 5.71 GJ per million NTD (17.22%) compared to 2022.

Note 1: The scope of energy management disclosure in 2023 includes the following operational sites: BenQ Materials headquarters, Taoyuan Plant, Longke Plant, Yunke Plant, Suzhou Plant, Wuhu Plant, Sigma Medical Materials, Hailu Plant, BMC (Dormitory), BMM, and DTB.
Note 2: The energy disclosure data for 2021-2022 has been updated (excluding subsidiaries). The disclosed data does not include subsidiaries (Web-pro, Cenefom, Genejet Biotech ), which are expected to complete third-party verification and be included in the disclosure scope in 2024.
Self-developed renewables
Since 2021, various plants have been constructing solar power generation equipment to supply electricity internally, thereby reducing external electricity purchases and carbon emissions. In 2023, new solar power generation equipment projects were completed and put into use at the Yunke Plant and the Taoyuan Plant. The total annual power generation for all plants reached 2.796 million kWh in 2023. In 2024, the company plans to continue expanding the solar power generation equipment at the Yunke Manufacturing Plant 1. It is estimated that the total power generation for all plants will reach 3.6 million kWh in 2024.

Action and Performance of Reduction
To mitigate global warming and reduce the operational risks brought by climate change while enhancing green production effectiveness, we continue to take actions in energy saving, emission reduction, green manufacturing, and circular utilization. Through various means, we aim to reduce the use and consumption of energy resources. In 2023, we implemented a total of 23 electricity-saving projects, with an annual electricity savings of 1.4136 million kilowatt-hours, reducing carbon emissions by 732.75 tons of CO2e. Additionally, we executed 5 natural gas-saving projects, with an annual natural gas savings of 87,800 cubic meters, reducing carbon emissions by 178.40 tons of CO2e. In 2024, we will focus on introducing large equipment for steam boilers, waste heat recovery systems for air compressors, high-efficiency motors, replacing lighting fixtures with energy-saving LED types, and upgrading fan filter units to DC energy-saving motors. We will continue to promote energy-saving and carbon-reduction measures to reduce energy consumption.
