Implementation Status of Environmental Management Policies
I. Sustainable Governance and Oversight
LeadSun Greentech has established a Corporate Governance and Sustainability Committee responsible for overseeing and supervising the implementation of the Company’s environmental management initiatives, including progress on greenhouse gas (GHG) inventory activities. Through regular meetings, the Committee reviews the status of key environmental management initiatives and provides discussion and guidance on related issues to ensure the continuous implementation and effective execution of environmental management measures. In 2025, the Corporate Governance and Sustainability Committee convened four meetings, with a 100% attendance rate among committee members.
II. Sustainable Environmental Management of Suppliers
LeadSun Greentech Group has formulated a “Supplier/Contractor Management Policy” and “Contractor Occupational Safety and Health Management Guidelines” to define key environmental management requirements for suppliers and contractors. Suppliers and contractors are also required to sign the Company’s “Corporate Social Responsibility Commitment,” which includes commitments to comply with international environmental management laws and standards, avoid the use of hazardous materials, properly handle or recycle waste, and adopt appropriate environmental management mechanisms to reduce the environmental impact of their operations. To date, a total of 62 suppliers and contractors have signed the above commitment. In addition, no incidents occurred in 2025 in which cooperation was terminated due to suppliers’ or contractors’ violations of environmental management regulations.
III. Greenhouse Gas Emissions and Resource Management
Since 2021, the Company has conducted annual greenhouse gas inventories. The results indicate that the primary source of GHG emissions is energy consumption at the headquarters office. In response, the office has progressively adopted high-efficiency lighting equipment and continues to review and optimize energy management measures. At the end of 2025, the Company initiated a Scope 3 greenhouse gas inventory to comprehensively establish baseline emissions data, which will serve as a reference for future carbon reduction planning.
The office has also gradually adopted environmentally friendly office supplies, such as FSC-certified copy paper and paper towels. Internal announcements and communications are primarily conducted via email or messaging platforms to reduce paper usage. Office waste is managed in accordance with the building’s waste management regulations, with recyclable materials sorted and collected by on-site environmental staff and subsequently processed by legally qualified environmental service providers.
IV.Air Quality Management
The dedicated unit responsible for air pollution control at our project sites is the Operations Department. All construction sites comply with relevant environmental protection regulations, including the Air Pollution Control Act, the Regulations for Air Pollution Control Facilities at Construction Projects, and local environmental requirements at each project location. During construction, perimeter fencing is installed around the site to reduce the dispersion of construction dust and its impact on the surrounding environment. Water spraying measures are applied to exposed surfaces to suppress dust generation. In addition, vehicle high-pressure washing facilities are installed at site entrances and exits to clean the bodies and tires of incoming and outgoing vehicles. Road cleaning operations are also carried out as needed based on construction conditions to maintain the surrounding air quality.
V.Stakeholder Engagement and Information Disclosure
In 2025, the Company published its first Sustainability Report in accordance with the GRI Standards, disclosing its management approaches and performance in the areas of environmental management, sustainable society, and corporate governance. At the same time, the Company established a dedicated “Sustainability” section on its official website as a platform for stakeholder engagement, proactively disclosing its responses to sustainability-related issues and relevant information to enhance transparency and deepen stakeholders’ understanding of the Company’s sustainability initiatives.
VI.Environmental Management and Environmental Benefits
Through the development of renewable energy projects, the Company generated approximately 2.21 million kWh of green electricity in 2025, resulting in an estimated carbon reduction of about 940 metric tons of CO2e. Based on the current government carbon fee of NT$300 per metric ton, this corresponds to approximately NT$280,000 in external environmental benefits.
Greenhouse gas, energy and water resource reduction management policies
I. Greenhouse Gas Management
The Company has designated the Sustainability Office as the dedicated unit responsible for greenhouse gas (GHG) management. This unit is responsible for formulating GHG management policies and promoting emissions reduction. The relevant policies and implementation status are outlined as follows.
(I) Reduction Target: Since 2025, our company has included greenhouse gas inventory in the consolidated financial statements of significant subsidiaries; therefore, the base year has been adjusted to 2025. Our company is committed to continuously promoting greenhouse gas management, setting a reduction target of 5% in greenhouse gas emissions (Category 1 and Category 2) by 2030 (5 years later) compared to the base year, and will gradually reduce greenhouse gas emissions generated during operations.
The guidelines aim to gradually reduce greenhouse gas emissions generated during operation.
(II) Promotion Measures
1. Promotion of energy-saving and carbon-reduction behaviors
(1) Promote the turning off of lights during lunch break to reduce office electricity consumption.
(2) Promote the practice of turning off computer mainframes and screen power after get off work to avoid long-term standby power consumption.
(3) Enhance the awareness of energy conservation and carbon reduction among all employees through internal promotion.
2. Management of official vehicles and office procurement
(1) Gradually replace fuel vehicles and give priority to electric vehicles as the choice for official vehicles.
(2) Prioritize the purchase of electrical equipment and office supplies with environmental protection labels.
(III) Circumstances of Completion
-
The scope of the 2023 greenhouse gas inventory audit covered the consolidated parent company and its major subsidiaries: Lisheng Energy Technology Co., Ltd., Xiangyin Sustainable Energy Co., Ltd., and Liwei New Energy Co., Ltd., establishing organizational boundaries with 100% operational control.
-
The 2023 greenhouse gas inventory audit results have passed the third-party verification (ISO14064-1:2018) by ARES International Certification Co., Ltd..
-
The company's greenhouse gas emissions from 2023 to 2024 are shown in the table below. Greenhouse gas emissions increased in 2023 compared to 2024; this is mainly because the scope of the greenhouse gas inventory audit was included in the consolidated financial statements of subsidiaries starting in 2023, while the audit scope in 2023 only covered the parent company, hence the difference.

II. Energy Management
The dedicated unit responsible for the Company’s energy management is the Administration Department, which is responsible for formulating energy management policies and promoting energy reduction. The relevant management policies and implementation status are as follows.
(I)Reduction Target: Our company operates as an office, uses all externally purchased electricity, and improves energy efficiency by aiming to reduce total energy intensity by 1% annually or per capita energy consumption by 1% annually.
(II) Promotion Measures
1. Air conditioning system optimization
(1) Set air conditioner temperature and time control
(2) Regularly maintain the equipment to keep the system running in optimal condition.
2. Promote energy conservation
(1) Turn off the lights when you are done using the meeting room.
(2) Encourage employees to take public transportation to work.
(3) Promote energy conservation by turning off the lights during lunch break.
(III) Circumstances of Completion
(1)Please see the table below for the company's energy usage in 2023 and 2024. The target of a 1% reduction in per capita energy consumption compared to 2024 has been achieved by 2025.
(2)Given that office energy consumption is the primary source of energy consumption (accounting for over 60% of total energy consumption), to reduce the environmental impact of electricity use, green electricity transfer was implemented in the Xizhi office starting in 2024, increasing the green electricity usage rate to 7.07%.
(3)Further assessment of the impact of energy on the company's operations reveals that the company's electricity consumption is mainly in the office, with stable consumption levels. Electricity price fluctuations have a limited impact on operating costs, and power outages have a short-term and recoverable impact. Furthermore, the increasing demand for low-carbon energy will help expand the company's renewable energy business and increase the potential market size. Overall, energy-related risks have a low impact on operations.
Note 1: 1 kilowatt-hour of electricity = 3.6 million joules (J) of energy consumption.
Note 2: 1 gigajoules (GJ) = 1,000,000,000 joules (J).
Note 3:The energy conversion coefficients are calculated based on fuel calorific values (gasoline: 7,586 kcal/L; diesel: 8,636 kcal/L) and the joule conversion factor (1 kcal = 4.186 kJ).
Note 4: To reflect monthly changes in employee numbers, the energy consumption per employee in this report is calculated based on the "average number of employees per month" for the current year. The formula is as follows:
Energy consumption per employee = Total energy consumption / Average number of employees per month for the current year.
III . Water Resources Management
The Company has designated the Administrative Management Department as the dedicated unit responsible for water resource management. This unit is responsible for formulating water management policies and promoting water conservation. The relevant policies and implementation status are outlined as follows.
(I)Reduction target: The company’s water resource management is guided by the annual water intensity reduction target of 1% , and promotes water conservation in the office.
(II) Promotion Measures
Our company operates as an office. The Taipei headquarters employees use tap water, primarily for office use and domestic purposes. Water consumption...
This is not a material issue for the company, and all wastewater generated from water use is domestic sewage, discharged through the building's plumbing system; the main management measure is to promote awareness on a daily basis.
Reduce unnecessary water waste in daily work and raise employees' awareness of water conservation.
(III) Circumstances of Completion
-
Please see the table below for details of our company's water resource usage in 2024 and 2025. In 2025, we achieved our goal of reducing per capita water consumption by 1% annually.
-
Our company is committed to reducing water resource usage based on corporate social responsibility. However, our assessment revealed that our company's per capita daily water consumption in 2024 was only approximately 23 liters, far lower than the average daily domestic water consumption of 337 liters per person in Taipei City in 2024 (referencing publicly available data from the Water Resources Agency, Ministry of Economic Affairs). Therefore, water consumption is not significant to our company.
Note 1: Water resource usage estimates are based on the Taipei City Water Department's official website.
Note 2: The amount of tonnage used is calculated based on the monthly share of fees paid to the management committee.
Note 3: Considering the office is located in a building with a well-developed water supply network and there is no process water usage, the estimated water intake is approximately equal to the total water consumption, and the water consumption is close to at zero.
IV . Waste Management
The dedicated unit responsible for the Company’s waste management is the Administration Department, which is responsible for formulating waste management policies and promoting waste reduction. The relevant management policies and implementation status are as follows.
(a) Reduction target: Our company implements measures to reduce waste generated during operations from the source, aiming to effectively reduce the total amount of waste emissions. We have set reduction targets of "reducing waste generation intensity by 1%" or "reducing per capita waste generation by 1% per year".
(II) Promotion Measures
As the Company operates primarily in an office-based environment, the main type of waste generated is general municipal waste. Waste management at the Taipei headquarters is conducted in accordance with the building management committee’s waste disposal regulations (Farglory Financial Center). Waste is sorted and managed accordingly, and collected and processed by legally authorized third-party environmental service providers commissioned by the building management.
In addition, the Company promotes environmentally friendly practices in daily operations, including encouraging employees to bring reusable bags, cups, and utensils, reducing the use of single-use items, and properly sorting waste into three categories: recyclables, food waste, and general waste.
Our company values the environment and has established our own "Waste Management Regulations and Decommissioning Procedures upon Expiration of the Operation Period" for sites under development or operation, serving as the management basis for the development and operation process. Our management procedures ensure compliance with relevant environmental protection and resource recycling regulations; contracts also require construction contractors and related units to entrust waste disposal companies approved by the competent authorities to handle optoelectronic modules in accordance with government regulations, ensuring proper recycling and disposal of waste.
(III) Circumstances of Completion
(1)Please see the table below for the total waste emissions of our company in 2024 and 2025. The difference between 2024 and 2025 is likely due to a significant increase in waste from gifts and gift boxes generated during the Lunar New Year and Dragon Boat Festival. Furthermore, the 2024 data was calculated using data from the second half of the year, not monthly, hence the discrepancy.
(2)Based on the average number of employees per month, the per capita office waste generation in 2024 is estimated at 0.0487 metric tons, and in 2025 at 0.0394 metric tons, achieving the set annual reduction target.
The total amount of waste generated in 2024 and 2025 is presented in the table below. The difference between the two years is assessed to be primarily due to increased waste from gift packaging during major holidays, such as the Lunar New Year and Dragon Boat Festival. In addition, the 2024 data was extrapolated from the second half of the year rather than calculated on a monthly basis, which may have contributed to the variance.
(3)The Company remains committed to waste reduction as part of its corporate social responsibility. Based on internal assessment, the Company’s average daily general waste generation per employee in 2024 was approximately 0.075 kg, which is significantly lower than the Taipei City average of 1.16 kg per person per day (based on publicly available data from the Taipei City Department of Environmental Protection). Therefore, waste generation is not considered a material issue for the Company.
(4)As the Company operates primarily in an office-based environment, no hazardous or toxic waste has been generated in the past two years. The Company expects to maintain zero hazardous waste generation in the coming years.
Note 1: The Taipei headquarters is an office-based facility and generates only general municipal waste. Waste is regularly handled and processed by the building management committee. The total waste volume is estimated based on the proportion of the Company’s office area relative to the total floor area of the building.
Note 2:There are no statistics on the items to be reclaimed from the 113-year-old building.
Note 3: For 2024, waste collection by the building management committee commenced in July; therefore, the reported amount only includes the period from July to December, totaling 0.6816 metric tons. When annualized, the estimated total for the full year is 1.3632 metric tons.
