Environmental Sustainability Policy and Management
THSRC established the Environmental Management Committee with the President serving as the chair and heads of relevant departments as members to assist the Chairman in fulfilling environmental management responsibilities. The Committee supervised the implementation and communication of environmental management systems from a corporate perspective to ensure the suitability, adequacy, and effectiveness of the system. The Committee conducted 21 environmental quality management audits in 2025 to verify the performance of environmental management systems at all depots and stations. THSRC convened quarterly environmental management work meetings to monitor the implementation progress and status of environmental goals and implemented measures to mitigate environmental impact while complying with environmental regulations to improve the quality of the environment. Environmental protection remains a critical component of THSRC's corporate social responsibility. THSRC established the "THSRC Environmental Policy", which was approved by the Chairman for public disclosure, to implement comprehensive environmental protection work.
To respond to global initiatives for attaining net zero, THSRC obtained ISO 14001 Environmental Management System certification and became the first company in Taiwan's rail service industry to attain ISO 14001 certification in 2020 and received the recertification in 2023 (valid until September 24, 2026). THSRC completed the inventory of company-wide GHG emissions (Scope 1, 2, and 3)and passed external third-party verification to obtain the ISO 14064-1:2018 certificate each year. THSRC is also committed to environmental protection, GHG emission reduction, waste reduction, and enhancing environmental awareness among employees and suppliers. THSRC invested a total of NT$127,241 thousand in environmental projects in 2025. The expenditure increased by approximately 44.88% compared to 2024 due to the construction of the TK41 west noise barrier and the design of the TK141+250 east noise barrier. THSRC will continue to minimize environmental impacts from operations and use regular GHG inventories, carbon reduction initiatives, water conservation, and waste recycling management to achieve environmental sustainability goals.
Environmental Protection Expenditure in 2024–2025
Environmental Sustainability Targets and Strategies
Strategies
- Established operation safety and environmental risks relevant units (e.g., Environmental Management Committee) to strengthen the management and supervision mechanism and effectively implement implementation measures.
- Established Greenhouse Gas Inventory Audit List, conduct total inventory and verification, and study and formulate reduction measures and priorities.
- Through the Task Force on Climate-related Financial Disclosures (TCFD), climate risks were identified, and the resilience of high-speed rail in response to climate risks was assessed.
- Continue to promote the equipment optimization, personnel education and training, to improve energy conservation and carbon reduction.
2025 Goals and Results
- The company-wide greenhouse gas (GHG) inventory (with 100% coverage) has been verified and obtained ISO 14064-1: 2018 certificate.
- The total carbon emissions from electricity and fuel consumption in 2025 were 317,285.15 metric tons. The carbon emission per passenger-kilometer was 23.079 grams of CO2e, representing a 5.45% decrease compared to 24.409 grams in 2024.
- Through equipment elimination and optimization and Energy Saving Driving Program, electricity consumption in 2025 was reduced by 17,548 thousand kWh compared to the base year (2010).
Targets (Short Term: 2026; Mid-Long Term: 2027-2028)
Short Term
- Continue to conduct company-wide greenhouse gas inventory and verification every year.
- Continue to operate Energy-saving Train Operation plan.
- "Carbon emissions per person-kilometer" aims to reduce by more than 1.5% per year.
Medium-Long Term
- THSRC will continue to advance its net-zero transition, implement deep energy-saving initiatives, and enhance the utilization of renewable energy, in response to the government's "2050 Net-Zero Carbon Emissions" goal.
Strategies
- Establish resource use and management policies (including electricity consumption, water resources, and waste management), regularly review targets, and promote green initiatives such as renewable energy adoption and circular resource practices.
- Establish a dedicated resource use and management taskforce to strengthen management mechanisms and ensure effective implementation of related measures.
- Organize environmental training program to strengthen employees and environmental management representatives of each unit familiarity with environmental laws and regulations and environmental protection awareness and deepen environmental sustainability development concept.
- Continuously enhance environmental management practices through an environmental management system (EMS) and obtain external verification to ensure management effectiveness and compliance.
2025 Goals and Results
- Continuously pass the ISO 14001:2015 environmental management system re-examination (valid until September 2026).
- In 2025, electricity consumption per passenger trip was 1.14 kWh, representing a 5.03% reduction compared to 1.20 kWh in 2024.
- Water consumption per passenger trip decreased by 3.40% compared to 2024 (0.0095 m³ per trip).
- In addition, water footprint inventories were expanded and completed for 12 stations in 2025, and ISO 14046:2014 verification statements were obtained.
- The recycling rate of natural waste is 24.5%, and there are no oil, fuel, chemical substances, or waste leakage.
Targets (Short-Term: 2026; Mid-Long Term: 2027-2028)
Short Term
- Continue to conduct company-wide greenhouse gas inventory and verification every year.
- Continue to operate Energy-saving Train Operation plan.
- "Carbon emissions per person-kilometer" aims to reduce by more than 1.5% per year.
Mid-Long Term
