In line with the Company's operational characteristics and risk management policies, it systematically identifies, analyzes, assesses, and responds to potential impacts arising from climate change, thereby enhancing organizational resilience, ensuring operational stability, and achieving strategic objectives. Through this climate management framework, Quanta consolidates observations and evaluations from business units on climate risks and opportunities, and categorizes them according to factors such as timing, severity of impact, likelihood, and scope, to identify short-, medium-, and long-term risks and opportunities. Identified risks include physical risks (such as extreme climate events and water resource shortages) and transition risks (such as regulatory changes, market demand shifts, and low-carbon technology challenges), while potential opportunities include changes in customer behavior, alternative transportation models, and renewable energy adoption. The overall management process follows five key stages: risk identification, measurement, monitoring, reporting and disclosure, and response. Under the corporate governance structure, the Sustainable Development Center reports directly to the President's Office to ensure that climate risks are integrated into corporate decision-making. Relevant identification results and management outcomes are disclosed annually in the Sustainability Report, Annual Report, and on the Company's official website, with proactive engagement with stakeholders to strengthen transparency and external trust.

To address the potential impacts of climate change on business operations, Quanta has established a systematic risk and opportunity assessment process, which includes four major steps: data collection, identification, materiality assessment, and response strategy.

Climate Risk and Opportunity Assessment Process

  1. Collection Phase: Quanta regularly monitors international climate policies, industry trends, and market developments, and integrates operational data and project experience from various internal departments. These serve as the foundational inputs for assessing climate-related risks and opportunities.
  2. Risk and Opportunity Identification: Through internal cross-functional discussions and with reference to the four core disclosure pillars of the Task Force on Climate-related Financial Disclosures (TCFD)-governance, strategy, risk management, and metrics and targets-Quanta systematically identifies potential climate-related risks and opportunities that are closely tied to its operations. This includes short-, medium-, and long-term physical risks (both acute and chronic) as well as transition risks.
  3. Materiality Assessment: Prioritize various risks and opportunities based on their likelihood of occurrence and potential impact, identifying material issues to serve as the basis for the Company's sustainability strategy and action planning.
  4. Response Strategy and Financial Impact Assessment: For each identified risk and opportunity, the relevant specialized departments shall formulate concrete management approaches and mitigation strategies, continuously monitor the effectiveness of management and progress of improvements, and regularly report to senior management and the Board of Directors to ensure the effective operation of decision-making mechanisms and governance performance.

3.1.2. Climate Commitments and Actions

Climate Response Strategy

Aligned with the TCFD framework, Quanta systematically identifies and assesses the risks and opportunities arising from climate change. The Company collects analyses from business units regarding potential climate impacts, considering factors such as timing, impact severity, probability, and scope. Based on these factors, climate-related risks and opportunities are identified across short-term (1-3 years), medium-term (3-5 years), and long-term (more than 5 years) time horizons. The risk categories are primarily divided into two types: Physical risks include short-term climate events (e.g., extreme rainfall, droughts, tropical cyclones) and long-term climatic trends (e.g., changes in average precipitation) that may pose potential threats to operations and supply chains. Transition risks include regulatory pressures associated with the shift to a low-carbon economy (such as carbon taxes, cap-and-trade programs, and emissions trading schemes), market changes (such as demand and price volatility for low-carbon products), and technological challenges (such as investments in new technologies and the associated transformation costs).To strengthen the integration of climate risk management, Quanta has established a series of climate-related policies, including the "Greenhouse Gas Policy," "Environmental Protection Policy," and "Net Zero Emission Climate Declaration". These serve as the common foundational guidelines for the entire Group's sustainable governance and action implementation, guiding all sites to advance carbon reduction and climate resilience efforts under a unified strategic direction. Conversely, the climate transition may also present potential opportunities. Quanta has identified key opportunity areas such as shifts in customer preferences towards sustainable products and green supply chains, exploration of low-carbon alternative transportation modes, and operational advantages from adopting renewable energy and low-carbon manufacturing processes. The aforementioned risks and opportunities have been incorporated into Quanta's climate strategy assessment process and are continuously reviewed on a rolling basis to evaluate their potential financial and operational impacts. The detailed identification results are listed in the table below.

Regarding the physical risks associated with climate change, Quanta assesses the potential impacts of extreme weather events and long-term climatic shifts on its operations, drawing on climate data and international scenario simulation results. Shortterm risks primarily stem from extreme rainfall, drought, and tropical cyclones, which may lead to damage at operational sites, supply chain disruptions, or increased operating costs. According to simulation data, the probability of such events occurring before 2040 is approximately 33% to 50%, with a moderate impact intensity and an effect range across Quanta's major operational locations.

Additionally, Quanta has conducted an analysis of physical risks that may arise under scenarios of extreme rainfall and drought, including flooding, landslides, debris flows, and water shortages. The analysis references multiple sets of international climate scenario combinations, such as SSP and RCP, to examine temperature rise pathways and socioeconomic assumptions under cross-scenario variations. This simulation of the frequency of different extreme climate events and their potential impacts on operational sites serves as a critical basis for Quanta's climate adaptation strategies and mediumto long-term infrastructure planning. In the scenario analysis of extreme climate events, Quanta has incorporated multiple international standard scenarios including SSP1- RCP2.6, SSP2-RCP4.5, SSP3-RCP7.0, and SSP5-RCP8.5 to assess the exposure levels of its global operational sites to acute physical risks such as flooding, debris flows, and landslides. The assessment results indicate that the majority of Quanta's global sites and assets are located in areas classified as no-risk zones, with the overall level of physical risk assessed as relatively low.

Regarding the physical risks related to water resources, Quanta has conducted a mediumto long-term trend assessment specifically focusing on water scarcity risks. The results indicate that under the scenarios SSP2-RCP4.5, SSP3-RCP7.0, and SSP5-RCP8.5, the Taoyuan and Kaohsiung regions in Taiwan are identified as facing medium to high levels of water scarcity risk (as indicated by the color blocks in the figure). Moving forward, Quanta will continue to closely monitor the extent of the impact and the trend of changes. In the overall physical water resource risk analysis conducted under baseline conditions, it was shown that QMB (Quanta Manufacturing Bangkok) is identified as being in a higher-risk area under the SSP1-RCP2.6, SSP3-RCP7.0, and SSP5-RCP8.5 scenarios. QSMC (Shanghai plant) is categorized as a high-risk level, while other plants such as QCI (Taiwan) and QCMC (Chongqing) are mostly classified as medium to low risk (indicated by triangles in the figure). Quanta will continue to strengthen its short-, medium-, and long-term physical risk monitoring mechanisms based on international climate scenario simulation results and the risk levels of each operational site. Additionally, by integrating water resource management strategies, the Company aims to reduce the potential impact of climate risks on operations, thereby enhancing overall corporate resilience.

From 2024 through the first half of 2025, the Group Headquarters' Sustainable Development Center is leading a series of educational training and gap analyses for sites that had not yet undertaken GHG inventories. A total of 17 project sessions were held to assist these locations in rapidly enhancing their management capabilities and operational foundations. Quanta plans to complete greenhouse gas inventories for all major operational sites across the entire Group, including subsidiaries, by 2026, and to obtain third-party verification. These efforts are designed to strengthen the foundation of carbon management and respond to international sustainability disclosure and carbon reduction trends.

Additionally, in response to the carbon emission control policies of local governments at various operational sites, Quanta actively monitors and complies with the carbon emission regulations applicable to each operational location and cooperates with local governments in reporting emission volumes. In Taiwan, the carbon fee system has been officially announced and implemented. Carbon fees are imposed on emission sources at any single operational site with annual emissions exceeding 25,000 metric tons of CO₂e. Quanta has also initiated internal audits and potential cost estimations to support inclusion in cost assessments and carbon reduction strategy planning, continuously enhancing the low-carbon transition capabilities of each operational site.

In 2024, Quanta conducted its greenhouse gas (GHG) inventory in accordance with the ISO 14064-1:2018 standard, covering both qualitative and quantitative assessments of Category 1 (direct GHG emissions) and Category 2 (energy indirect GHG emissions). The inventory included seven types of gases: carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF₆), and nitrogen trifluoride (NF₃). The primary sources of emissions include natural gas, diesel, gasoline, liquefied petroleum gas (LPG), CO₂ fire extinguishers, methane emissions from septic systems, refrigerant leakage, and purchased electricity. According to the analysis of historical statistical data, purchased electricity remains the primary source of the company's carbon emissions. In 2024, greenhouse gas emissions generated from purchased electricity based on market benchmarks account for more than 89.44% of the total emissions in Scope 1 and Scope 2 categories.

The year 2024 marks Quanta's first group-wide greenhouse gas inventory, with the scope expanded to cover all subsidiaries within the Quanta Group. The inventory was aligned with the Group's financial reporting boundaries to ensure greater completeness and consistency in disclosure. At the same time, the 2023 inventory data was also adjusted to align with the same boundary criteria, facilitating subsequent trend tracking and annual comparisons. In 2024, Quanta's total carbon emissions (market-based) amounted to 276,122.3273 metric tons of CO₂ equivalent. The carbon emission intensity was approximately 0.1957 metric tons per million NTD in revenue. Compared to 2023, the total carbon emissions decreased by approximately 13.34%.

For Scope 3 greenhouse gas emissions (other indirect emissions), as 2024 marks the Group's first completion of a comprehensive Scope 1 and Scope 2 inventory, internal efforts are currently underway to develop methodologies and consolidate data for Scope 3 assessment. The Group expects to finalize a standardized Scope 3 inventory framework and calculation methodology by 2025, with formal disclosure planned in the 2026 Sustainability Report. This will serve as a significant step toward expanding the carbon management boundary, addressing supply chain risks, and responding to international disclosure trends.

Wastewater Management

Quanta places great importance on the treatment of wastewater (including sewage) and its potential environmental impact. Domestic sewage contains organic pollutants as well as nutrients such as nitrogen and phosphorus. If not properly treated, it can easily lead to eutrophication of water bodies, thereby adversely affecting the aquatic ecological environment. To mitigate this risk, certain manufacturing sites with specific needs have installed primary wastewater treatment facilities, incorporating processes such as filtration, sedimentation, and flotation. Additionally, dedicated personnel conduct regular inspections and maintenance to effectively remove pollutants, ensuring that the water quality meets standards before discharge.

In addition, Quanta has also commissioned qualified third-party testing agencies to conduct regular water quality sampling and analysis at the manufacturing sites requiring monitoring, in accordance with local regulatory standards. In 2024, the wastewater treatment results at all factory sites complied with the local regulations. All sampling operations strictly follow the technical specifications issued by local authorities to ensure that the monitoring results are scientific and representative. Through standardized processing procedures and institutionalized monitoring mechanisms, Quanta continuously strengthens its responsibility for wastewater management, implements sustainable water resource utilization, and safeguards environmental quality.

Highlight Story 1

Safeguarding Water Sources through Adoption Initiatives, Corporate Practice of Local Sustainability

To reinforce its commitment to water resource conservation and ecological sustainability, Quanta Headquarters R&D Center, in collaboration with Huaya Park Management Consulting Co., Ltd., actively supported the local government's water co-governance initiative. They proactively adopted the upstream detention basin of Nankan River from the Taoyuan City Government Water Resources Department, working together to promote a governance model that is water-friendly and environmentally harmonious.

The detention basin was originally designed as a hydraulic facility to regulate stormwater runoff and mitigate flood risks. Following the launch of the adoption initiative, the project team embraced an ecology-oriented design approach, introducing native vegetation, creating ecological habitats, and constructing pedestrian walkways. As a result, the site was transformed from a single-purpose flood control installation into a multifunctional community water space that integrates ecological conservation, recreational use, and environmental education.

The implementation of this initiative not only enhances the water quality and retention capacity of the detention basin but also attracts the return of birds, insects, and other wildlife through habitat improvement, thereby strengthening ecosystem diversity. At the same time, it allows local residents to have close contact with natural water bodies, fostering a community consensus and sense of participation in water resource conservation, thereby realizing the sustainable concept of harmonious coexistence and mutual benefit between enterprises and local society.

Safeguarding Water Sources through Adoption Initiatives.

Waste Reduction

The Company upholds the principles of effective management and continuous reduction, systematically promoting waste management and reduction initiatives. Each operational site implements waste classification, collection, and recycling in accordance with local regulations. Through three major action directions-source waste prevention, third-party supervision, and data monitoring-Quanta applies and continuously refines a multi-faceted strategy aimed at reducing waste generation intensity, improving resource recycling efficiency, and increasing waste-to-resource conversion rates year over year.

In terms of source waste prevention, the Company focuses on equipment selection, process optimization, and supply chain management, implementing lean production and extending the lifespan of consumables. In 2024, the QCI saved 19.8400 metric tons of waste by improving the carrier cleaning operation process and reusing discarded wiping paper. On the other hand, Quanta requires suppliers to provide material certifications that comply with RoHS and REACH regulations, in order to restrict the use of highrisk chemical substances. Regarding third-party supervision, the Company selects qualified vendors holding waste disposal permits and establishes clear contractual terms requiring that no illegal cross-border disposal occurs. Additionally, the vendors must provide traceable waste treatment reports. Additionally, by conducting compliance audits annually, the quality and legality of contracted services are ensured. In terms of data monitoring, the Company has established a waste classification monitoring system covering packaging waste, domestic waste, and defective products from the manufacturing process. Through the use of weighbridge measurements and an automatic data uploading system, semi-annual summaries and annual cross-sectional comparative analyses are conducted to support ongoing improvement efforts. Through these initiatives, the Company has obtained UL2799 "Zero Waste to Landfill" certification for multiple manufacturing sites, with some achieving the highest platinum level standard, demonstrating the Company's efforts and achievements in resource circularity and waste reduction.

Air Pollution Management

The Company is committed to air pollution prevention and control, strictly managing waste gas emissions at its operational sites in accordance with relevant environmental protection regulations. This includes the control and monitoring of pollutants such as volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM). By installing appropriate treatment equipment and conducting regular maintenance, ensure that the emission concentration complies with regulatory standards. In addition, the Company has completely eliminated substances containing ozone-depleting substances (ODS) in all manufacturing processes, achieving zero ODS emissions each year. In 2024, the Company reported zero major environmental pollution incidents and received no related penalties.

Highlight Story 1

Milestone Towards Zero Waste Landfill-QCI, QSMC, and QCMC Achieve UL2799 Platinum Certification

To enhance waste management effectiveness, Quanta has actively adopted international certification standards and progressively implemented the "Zero Waste to Landfill Program" across its manufacturing sites. The program is guided by the globally recognized UL ECVP 2799 Zero Waste to Landfill standard, which emphasizes full transparency and traceability of all waste streams. All waste must be properly handled through recycling, reuse, or energy recovery, and is subject to stringent compliance controls, on-site inspections, and third-party audits to verify that landfill disposal is not used at the end of its lifecycle. When the overall waste conversion rate reaches 80% or above, the enterprise can obtain certification. In 2024, the Company successfully led multiple plants to obtain this international certification. The QCI, QSMC, and QCMC achieved platinum-level certification with a 100% waste conversion rate, while the QMB earned silver-level certification. In the future, Quanta will continue to advance toward achieving the goal of zero waste to landfill across all manufacturing sites, establishing a model that aligns with the vision of sustainable development.

Highlight Story 2

Implementation of Automated PCB Cleaning Equipment to Achieve Organic Solvent Recycling

To enhance process efficiency and reduce waste generation, QCMC has implemented fully automatic PCB cleaning and drying equipment in 2022. In the traditional process, cleaning excess solder paste from the PCB required multiple steps, including manual alcohol wiping, ultrasonic cleaning, hot water rinsing, and air gun drying. After switching to fully automated equipment, washing and drying can be completed in an integrated process, and organic solvents can be recycled and reused through the system, significantly reducing the generation of waste liquid. Using the year 2022 as the baseline (with 28.86 tons of waste organic solvent disposed), this improvement measure has achieved an actual reduction of 21.3610 tons in 2023, and a further reduction of 19.21 tons in 2024, demonstrating Quanta's ongoing commitment to process optimization and advancing toward green manufacturing.
