Sustainable issues
AOT pays attention to global climate action-related trends and follows the government’s net-zero transformation goals. We adopted The Climate-related Financial Disclosure (TCFD) framework in 2024 to integrate climate change risks into our risk management governance. We included climate change risk in ESG material topics and aligned it with business strategy. We analyze policies, market and technology changes, and reputation and physical risks to develop adaptation and mitigation strategies. We also disclose climate-related financial information to showcase our resilience and responsibility while enhancing stakeholder communication.
The implementation of climate-related information
| Fram | Item | Action Plan |
| Governance | The board’s oversight of climate-related risks and opportunities. | The highest responsibility unit for overseeing and governing the company’s climate-related risks is the board of directors, which approves the risk management policies and relevant regulations. The audit committee is responsible for overseeing and ensuring the implementation of risk management, reporting the climate risk management results to the board of directors. In the fourth quarter of each year, it oversees the implementation results of the current year and the work plan for the next year. |

||
| Impacts of Climate-Related Risks and Opportunities on Business, Strategy, and Financial Planning. | 1. Transition Risks: | |
| 1.1 Changes in customer behavior: ▪ Due to policy and regulatory requirements, switching to low-carbon energy results in higher product and operational costs. Therefore, the company simultaneously adjusts resource use efficiency (optimizing distribution processes, using recyclable materials, etc.) to help reduce operational costs. ▪ On the other hand, the company focuses on its climate change adaptation capabilities by implementing risk management and seizing opportunities. This includes using a low-carbon supply chain (green packaging, green circular manufacturing technologies, etc.), expanding product applications in green industries (electric vehicles, smart grid industry chain, etc.), and leveraging this as a green marketing strategy to enhance its image, ensure competitiveness, and increase customer base and exposure. 1.2 Rising raw material costs: ▪ Reduce the number of suppliers and control costs through bulk pricing. ▪ Evaluate and verify the use of recycled materials (e.g., reusing plastic from board material recycling). |
||
| 2. Physical Risks: | ||
| 2.1 Increased severity of extreme weather events such as typhoons and floods: ▪ Identify climate-related risks and transfer risks through insurance. The company purchases commercial fire insurance with additional typhoon and flood coverage. The coverage includes buildings, business renovations, business operations, machinery and equipment, and goods, to mitigate operational damage caused by climate change and extreme weather events. ▪ Assess flood and drought risks at the factory site, develop and implement risk mitigation measures to prevent site disruptions or impact on work safety. ▪ In accordance with the company’s “Emergency Response Plan,” fully utilize all available resources to ensure the handling of principles in the shortest time. This ensures that in the event of a climate disaster, the impact on personnel and financial losses is minimized. In case of a disaster, each unit should immediately report and take necessary rescue actions according to the emergency response process, followed by a post-incident investigation, analysis, review, and improvement. ▪ Each year, based on the established emergency response plan, relevant training should be conducted, and disaster drills should be held at least once. After the drill, the applicability of the emergency response plan should be reviewed in a timely manner to minimize losses caused by accidents. 2.2 Changes in rainfall (water) patterns and extreme shifts in climate patterns: ▪ Establish a comprehensive water monitoring system and emergency response procedures, with regular drills. ▪ Build backup water reservoirs and transport water to the factory site via water trucks during water shortages to maintain operations. ▪ In response to drought and water shortage risks, implement water-saving measures, prepare water trucks, and set up backup water reservoirs at each factory to ensure a 3-day supply of water. |
||

||
| Resilience in strategy, considering different climate-related scenarios. | 1. Referencing the 2°C Scenario by the International Energy Agency (IEA): Simulate and analyze the potential impacts of future climate change and set greenhouse gas reduction targets based on this scenario. This will help estimate future carbon reduction amounts and inform adjustments to operational strategies. 2. “Increased Severity of Extreme Weather Events such as Typhoons and Floods”: ▪ Under climate change, typhoons and heavy rainfall are expected to become more severe, potentially exposing company operations to natural disasters, causing operational disruptions or personnel casualties. ▪ SSP1-2.6: By mid-century and the end of the century, Taiwan’s average annual total rainfall will increase by approximately 12% and 16%. The average annual maximum one-day rainfall intensity will increase by about 15.7% and 15.3% by mid-century and the end of the century. ▪ SSP5-8.5: By mid-century and the end of the century, Taiwan’s average annual total rainfall will increase by approximately 15% and 31%. The average annual maximum one-day rainfall intensity will increase by about 20% and 41.3%. ▪ SSP5-8.5: By mid-century and the end of the century, the number of typhoons affecting Taiwan will decrease by approximately 15% and 55%, while the proportion of strong typhoons will increase by about 100% and 50%, respectively. The rate of change in typhoon-related rainfall will increase by about 20% and 35%. 3. “Average Temperature Rise”: ▪ SSP1-2.6: The average annual temperature by mid-century and the end of the century may rise by 1.3°C and 1.4°C, respectively. The number of days with temperatures above 36°C will increase, with an increase of about 6.8 days and 6.6 days by mid-century and the end of the century. ▪ SSP5-8.5: The average annual temperature by mid-century and the end of the century may rise by more than 1.8°C and 3.4°C, respectively. The number of days with temperatures above 36°C will increase, with an increase of about 8.5 days and 48.1 days by mid-century and the end of the century, with urban areas experiencing a more significant increase compared to other regions. 4. Scenario Simulation: ▪ The company refers to both SSP1-2.6 and SSP5-8.5 scenarios. The risk management team discusses the definitions of short, medium, and long-term periods, setting “1-3 years” as the short term, “3-5 years” as the medium term, and “6-10 years” as the long term, and conducts climate risk and opportunity assessments accordingly. Climate risk types include transition risks and physical risks, which are further divided into categories such as policy and regulation, technology, market, and reputation, along with immediate and long-term risks. Opportunities are categorized into resource efficiency, energy sources, products and services, market, and organizational resilience. ▪ Physical risks are simulated using the SSP5-8.5 scenario, which represents a high greenhouse gas emissions scenario, with greater likelihood and higher risk for physical risks. ▪ Transition risks are simulated using the SSP1-2.6 scenario, where temperatures are closer to a 2.0°C scenario, aligning with net-zero emissions and current trends. This scenario could lead to regulatory risks, such as amendments to the Greenhouse Gas Reduction and Management Act, which could increase regulatory risks for businesses. ▪ Regarding the financial impact of physical risks, extreme weather events that lead to workplace stoppages and production line shutdowns, as well as water shortages caused by extreme drought, would increase operational costs due to water transportation and storage. Based on scenario simulations, the financial impact of these physical risks is limited, with an estimated annual impact of no more than 0.5% of revenue. ▪ In terms of transition risks, since the company’s combined Scope 1 and Scope 2 greenhouse gas emissions do not exceed 10,000 tons, it is currently below the carbon tax threshold. Additionally, the company’s contract capacity of 2100 kW does not meet the renewable energy development regulation’s contract capacity standards. Therefore, transition risks are expected to have limited financial impact in the short term, but the company will continue to monitor regulatory changes to comply with legal requirements. |

Considering factors such as risk tolerance, cost-effectiveness of risk responses, and the potential reduction in likelihood and impact, appropriate risk management measures are implemented to keep the risks within acceptable levels. 2. Climate Risk Supervision and Management: The corporate governance leader plans, leads, and supervises the risk management team in climate risk identification, assessment, control, and monitoring. Each year, the team regularly reports climate risk management information, execution status, and subsequent follow-up improvements, response measures, and strategic objectives to the audit committee and the board of directors. 3. Risk Reporting and Disclosure: In addition to disclosing relevant information as required by regulatory authorities, the risk management team also publishes information related to corporate risk management in the annual report and on the company’s website to provide external stakeholders with reference materials. |
|
| How the identification, assessment, and management process of climate-related risks can be integrated into the company’s overall risk management system. | The company’s audit committee is responsible for overseeing climate risk management. The risk management team follows the “Risk Management Policies and Procedures” to identify, analyze, assess, and control operational risks within the group. Climate risks are integrated into the overall risk management framework, where they are identified and assessed according to established procedures. After formulating appropriate response policies and strategies, the relevant departments implement these measures and report the execution results to the board of directors. | |
| Indicators and targets | Explain the indicators used by the company to assess climate-related risks and opportunities following its strategy and risk management process. | In terms of climate change mitigation, the company uses greenhouse gas emissions per unit as the main quantitative evaluation key indicator, along with other indicators such as electricity intensity, waste intensity, water intensity, and greenhouse gas emission intensity. |
| Scope 1, Scope 2, and Scope 3 Greenhouse Gas Emissions and Associated Risks: | Starting from 2023, the company will continue to conduct inventory of greenhouse gas emissions for Scope 1, 2, and 3, following the ISO 14064-1 standard. The greenhouse gas emissions (in metric tons of CO2e) for 2024 are as follows: | |
| Scope 1: 477.4790 (metric tons CO2e). Scope 2: 6,687.5042 (metric tons CO2e). Scope 3: 1,679.8791 (metric tons CO2e). |

Greenhouse Gas (GHG) Verification Statement
Waste Management
Our company has implemented an ISO 14001-certified waste management system to minimize our environmental footprint. We categorize our waste into two main types: general waste and industrial waste. General waste, which includes employee household waste and non-process-generated waste like paper, plastic, and aluminum cans, is managed by certified disposal companies.
Industrial waste primarily includes waste solvents, anti-static metal bags, wiping cloths, and sludge resulting from wastewater treatment. Our company has implemented measures for resource recycling and waste classification for many years. We have entrusted all scrap materials to qualified recycling vendors for processing. In terms of packaging materials, we strive to use recycled materials to minimize environmental impact. For example, anti-static metal bags are reused until their anti-static properties diminish, after which they are disposed of.
All waste removal and processing vendors possess the necessary clearance and handling permits, and we have signed contracts with them. The company conducts regular annual visits to waste processing facilities to understand the waste treatment processes. Additionally, each year, we perform TCLP tests on hazardous industrial waste (C-0301 & D-0902).
The specific waste management measures are as follows:
1. Promote various management programs through the ISO 14001 Environmental Management System, such as integrating operational checklists into an electronic format to achieve 100% paperlessness.
2. Implement resource recycling and reuse to enhance waste management and increase the resource recovery rate.
3. Design products that reduce volume and material usage to decrease waste generation.
4. Prioritize the use of recycled materials to achieve waste reduction and implement circular reuse.
5. Commission licensed vendors to handle waste disposal.
Waste reduction target: A 1% decrease in waste intensity per million unit compared to the previous year.
Waste reduction status: In 2024, waste totaled 61.22 tons, a decrease of 3.43 tons compared to 2023, representing a reduction rate of 5.31%.

Water Resource Management
According to the Environment Sustainable Index (ESI), Taiwan ranks among the top 18 water-scarce countries globally. To address the risks of water shortages, the management of water resources is a significant issue.
Our company is located in the Hsinchu Industrial Park in Hukou Township, Hsinchu County, with water sourced primarily from the Shimen Reservoir, First Baoshan Reservoir, Second Baoshan Reservoir, and the Toucian River. The water supply comes from the Taiwan Water Corporation Third District Management Office. Wastewater is discharged into the sewer system of the Hsinchu Industrial Park and treated at the central wastewater treatment plant before being released into the Qiedong River, meeting regulatory discharge standards.
According to the World Resources Institute’s (WRI) Aqueduct Water Risk Assessment Tool, a water pressure assessment was conducted for each of Rong Chuang Energy’s facilities. The results indicate that by 2030, even under the most pessimistic climate scenarios, the water resource pressure in the areas where our facilities are located will remain low to moderate (10%-20% Low – Medium risk), with no operations situated in “high” or “very high” water-scarce regions.
For water resource management, we ensure the reuse of process water without compromising quality, continuously maximizing water efficiency in our facilities, and increasing output with the same water usage. We have installed water meters in our production areas and buildings to monitor water consumption and reduce water use risks. Our company has set up wastewater treatment equipment, appointed personnel to manage environmental affairs, and obtained wastewater discharge permits. We have also been certified under the ISO-14001 Environmental Management System to effectively reduce negative impacts on the ecological environment.
The specific water resource management measures are as follows:
1. Install additional water storage facilities to implement water-saving management.
2. Establish a comprehensive water monitoring mechanism and emergency response procedures, with regular drills.
3. In response to drought risks, implement water-saving measures and prepare water tankers, establishing backup water pools with a three-day supply at each facility.
4. Sign contracts for water tanker services during drought periods to ensure water source allocation during dry seasons.
Water saving target: Achieve a 1% reduction in water intensity per million unit compared to the previous year.
Water reduction status: In 2024, water consumption was 22.13 ML, a decrease of 1.04 ML, representing a reduction rate of 4.5%.
