Climate change and energy transition are critical challenges that require global collaboration. PTI has established an Environment, Health, and Safety Committee composed of top-managers and cross-departmental representatives, to take charge of developing, coordinating, and implementing initiatives related to environmental sustainability and climate change. Moreover, to enhance resource efficiency, we have formed a cross-functional Energy Conservation Task Force with members from facilities, equipment, production, and environmental safety units. This task force sets performance indicators and proposes practical energy-saving measures. Through continuous validation of these initiatives, we strive to effectively and sustainably reduce energy consumption and improve operational efficiency.

Energy Management

PTI’s operating sites use electricity, natural gas, gasoline, and diesel as energy sources, with electricity accounting for the majority of consumption. No heat or other energy sources are used. The energy consumed is supplied by government-owned power generators, public natural gas utilities, and fuel stations. To monitor energy usage and enhance efficiency, we have implemented energy management and obtained ISO 50001 energy management systems certification for 8 plants. New facilities are designed with green building concepts to reduce energy and resource consumption. Environmentally friendly refrigerants with low global warming potential are utilized, while high-efficiency motors (IE3 or higher) are selected for rotating equipment. Site-wide energy-saving measures, such as cooling system upgrades, dryer replacements, water recycling, optimized machine settings, computer renewal, improved lighting, and after-hours shutdown protocols, have been adopted to reduce energy losses.

In 2025, an estimated 20,255,665 kWh of electricity was saved, reducing approximately 9,439.14 MTCO₂e emissions. This achievement met the energy-saving target of 1.5%.

PTI also evaluates the efficiency of its energy consumption. On the basis of a recent comparison of revenue and energy consumption, the energy intensity in 2025 was 0.053 GJ/NT$1,000, which was a 2.58% decrease compared to 2024. In the future, PTI will continue to pay close attention to energy efficiency, use renewable and alternative energy sources to protect the Earth.

PTI Energy Consumption and Energy Intensity

GHG Inventory

PTI has established a greenhouse gas (GHG) inventory management system with reference to the ISO 14064-1 GHG inventory standard and relevant domestic and international guidelines. The Company also refers to the GHG Protocol framework for disclosing Scope 1, Scope 2, and Scope 3 greenhouse gas emissions. In 2025, PTI completed its GHG inventory based on actual operational data from each operating site. The disclosed emissions cover direct GHG emissions (Scope 1), energy indirect GHG emissions (Scope 2), and other indirect GHG emissions (Scope 3). The total Scope 1 and Scope 2 emissions amounted to 329,818.51 MTCO₂e, with Scope 1 and Scope 2 accounting for 3.11% and 96.89%, respectively. Purchased electricity was the primary source of emissions.

To reduce greenhouse gas emissions and mitigate climate change impacts from operations, PTI continues to implement energy management and energy efficiency improvement initiatives, with an annual electricity-saving target of 1.5%. The 2025 GHG inventory was conducted in accordance with ISO 14064-1:2018 and verified by an independent third party. [GHG Verification Statement Link]

GHG Reduction for 2050 Net-Zero

In response to the global climate crisis and carbon reduction initiatives, PTI has set short-, medium-, and long-term greenhouse gas reduction targets based on the 2020 baseline year. These targets include a 5% reduction by 2025, 15% by 2030, and achieving net-zero emissions by 2050.

To fulfill this vision, we have actively promoted multiple strategies such as energy conservation, renewable energy deployment, and low-carbon product innovation. In 2025, a total of 161 energy-saving and carbon-reduction measures were implemented across factory operations and production facilities to reduce energy consumption and GHG emissions.

PTI continues to set annual energy-saving goals and improve electricity efficiency, supported by internal programs and incentive mechanisms that encourage active participation from both management and employees. All initiatives are carried out under the principles of measurability, reportability, and verifiability, and are aligned with the United Nations Sustainable Development Goal (SDG) 13: Climate Action, as we move steadily toward a low-carbon and sustainable future.

Climate Change Response (CDP and TCFD Disclosure)

In support of the Paris Agreement's goal of limiting global warming to within 2°C while striving to achieve the 1.5°C target, PTI has participated in CDP's Climate Change program since 2015 by responding to both the Climate Change and Water Security Questionnaires. In 2025, the Company received a B rating in the Management Band for the Climate Change and Water Security Questionnaires.

Since officially becoming a supporter of the Task Force on Climate-related Financial Disclosures (TCFD) in July 2020, PTI has proactively advanced its climate adaptation and mitigation efforts. The Company conducts annual assessments of climate-related risks and opportunities in accordance with the TCFD framework, covering both transition risks and physical risks. By evaluating the potential impacts of climate change on its operations and financial performance, PTI develops environmental management policies and corresponding response measures.

To address the impacts of climate change, reduce environmental risks, and ensure sustainable operations, PTI collaborates closely with employees, customers, and suppliers to accelerate the transition to a low-carbon economy. Together, we are committed to achieving net-zero emissions by 2050 and creating a sustainable future. For more details, please refer to the 2025 TCFD Report.

EHS Awareness Promotion

PTI recognizes that cultivating environmental protection awareness requires a deeply rooted and long-term approach. To continually enhance employees’ understanding of safety, environmental protection, and health promotion, we organize a series of educational campaigns starting from the theme of environmental sustainability. These efforts include multimedia exhibits, on-site demonstrations, and health-focused content aimed at deepening the concept of sustainability and reinforcing our corporate responsibility.
