Energy Management
In 2025, the main energy sources used were natural gas and purchased nonrenewable electricity, followed by automotive gasoline. In 2025, total energy consumption consisted of 8.7239 million cubic meters of natural gas, 113.4993 million kWh of electricity, including non-renewable electricity and renewable electricity, 10.8 thousand liters of gasoline for vehicles, and 8.2 thousand liters of diesel. Converted into heat units, total consumption amounted to 737,614.56 GJ, consisting of 697,393.82 GJ of non-renewable energy and 40,220.74 GJ of renewable energy, including 20,720.33 GJ of self-used renewable electricity, 19,785.38 GJ of purchased renewable electricity, and negative 284.97 GJ of renewable electricity sold. This represented an increase of 243,910.84 GJ compared with 2024, consisting of an increase of 233,604.75 GJ in non-renewable energy and 29,914.65 GJ in renewable energy, or an increase of 49.40%.
Using revenue as the denominator for total energy consumption, energy consumption intensity in 2025, defined as energy consumption per NT$1 million in revenue, was 41.33 GJ/NT$1 million, an increase of 14.78 GJ/NT$1 million, or 55.67%, compared to 2024.

Energy Transition – Use of Renewable Energy
In 2023, BenQ Materials followed Qisda Group’s renewable energy strategy target and moved up the original timeline for achieving RE100 from 2050 to 2040, while formulating a specific RE100 strategic pathway. In addition to continuously investing in self-built solar power generation systems for self-consumption, the Company actively cooperates with renewable energy retailers to gradually expand renewable electricity procurement, fulfilling its commitment to energy transition and net-zero carbon emissions.
In 2025, BenQ Materials’ annual renewable energy use reached 19,669.7 MWh, or 19.6697 million kWh, including:
• 5,755.7 MWh, or 5.7557 million kWh, generated by self-built solar power generation systems for self-consumption
• 5,496.0 MWh, or 5.496 million kWh, of externally purchased renewable energy.
• 8,418 MWh, or 8.418 million kWh, of China-issued GEC / I-REC renewable energy certificates purchased by China sites. The above renewable energy use has been used to offset carbon
emissions generated from purchased electricity at each plant during operations in 2025 as part of voluntary carbon reduction actions. Looking ahead, the Company will continue to increase investment in self-built solar power generation systems for self-consumption and further expand external procurement of renewable energy, steadily advancing toward the RE100 target set by the Group and the ESG Committee.
Self-developed renewables
Since 2021, the Company has successively built solar power generation equipment at each plant to provide electricity for plant use through self-generation and self-consumption, reducing purchased electricity and carbon emissions. In 2025, new solar power generation equipment projects were completed and put into operation at Yunlin Manufacturing Plant I, Manufacturing Plant II, and the recycling area of Manufacturing Plant III. Total electricity generation across all plants reached 5.1321 million kWh for the year. In 2026, the Company will continue to expand the scale of solar power generation equipment at the parking lot of Yunlin Manufacturing Plant I.

Emission Reduction Actions and Outcomes
To mitigate global warming and reduce operational risks arising from climate change, and to enhance green production performance, we continue to take action in energy conservation, emission reduction, green manufacturing, and circular use. Through various approaches, we reduce the use and consumption of energy and resources. In 2025, a total of 13 electricity-saving projects were implemented, with annual electricity savings totaling 652.7 thousand kWh and a reduction of 309.37 metric tons CO2e in carbon emissions. In 2025, a total of three natural gas-saving projects were implemented, with estimated annual natural gas savings totaling 493.6 thousand cubic meters and a reduction of 927.42 metric tons CO2e in carbon emissions.
Energy Review and Energy Performance Improvement
BenQ Materials conducts periodic energy reviews in accordance with its energy management system. Energy consumption and efficiency data for major processes, equipment, and systems are analyzed to identify Significant Energy Uses (SEUs) and opportunities for energy savings and energy performance improvement. The results of the energy reviews serve as a basis for energy-saving initiatives and continuous improvement in energy performance, with relevant improvement opportunities incorporated into energy management and energy-efficiency improvement plans for follow-up.

Internal Carbon Pricing and Carbon Fee
BenQ Materials has long supported national greenhouse gas reduction policies and actively invested in energy-saving and carbon-reduction initiatives. Since 2021, the Company has introduced an internal carbon pricing mechanism to manage potential future carbon emission risks and enhance internal carbon management awareness. Each year, reduction targets are established and implementation performance is reviewed through the ESG Committee governance platform.
During 2025, BenQ Materials reviewed and approved seven carbon reduction projects under its internal carbon pricing mechanism, with total approved funding of approximately NT$12.74 million. Projects with quantified GHG reduction benefits are expected to reduce at least 279.4 tCO₂e annually. In addition, one approved solar photovoltaic project is expected to generate approximately 408,985 kWh of renewable electricity per year.
