Energy Management Plan & Internal Carbon Pricing
Energy Management Plan
Policies
Environmental protection is an important part of THSRC's social responsibility. We treat the environmental issues such as environmental management, energy saving, water saving, waste reduction, green building, ecological conservation, environmental education, green procurement and local environmental care seriously. With the integration of international trends on environmental protection, THSRC pursue a sustainable business operation.
- Define our core business as 4T of Transportation, Technology, Taiwan and Touch, as we strive to provide green and intelligent service and seek to be the platform for advancement and enjoyment.
- Ensure that all corporate activities comply with environmental regulations and fulfill the commitments of environmental impact assessment.
- Strengthen the environmental protection concept for employees, contractors and passengers.
- Promote the effectiveness of green and low-carbon transportation services.
- Commit to improving environmental performance, developing and regularly reviewing environmental objectives to ensure that daily operations are carried out with appropriate processes and resources to prevent or mitigate environmental impacts.
Energy-Saving Targets
THSRC emphasizes energy conservation and carbon reduction, and continues to promote four major energy-saving schemes (autonomous energy conservation management, reduce electricity consumption, transfer peak electricity usage, and use electricity reasonably) at the Company's 5 maintenance depots and 12 stations. We also formulated plans to improve energy efficiency and build low-carbon stations, and established an annual electricity-saving target threshold of 0.86% per passenger trip for all sites (stations and maintenance depots). In 2024, our average electricity consumption per passenger trip (1.20 kWh) was reduced by 4% compared to 2023 (1.25 kWh). As of the third quarter of 2025, our average electricity consumption per passenger trip was 1.182 kWh, a reduction of 1.50% compared to 2024.
Energy-Saving Actions
Stations: Implement green building designs
THSRC station designs are based on sustainable “ecology, energy conservation, waste reduction, and health” concepts, and our stations implement various energy-saving measures based on local geographical conditions and environments to reduce impacts from building materials and air-conditioning. Miaoli Station, Changhua Station, and Yunlin Station were planned and designed using green building indicators, and were built by local vendors to reduce carbon footprints during construction periods. The stations also implemented greenery, energy conservation, solar power generation, and water retention measures based on the nine major green building indicators. The aforementioned three stations have all received green building certificates issued by the Ministry of the Interior (Miaoli Station received a Diamond Level certificate, Changhua Station received a Gold Level certificate, and Yunlin Station received a Gold Level certificate) as well as Green Building Certification Plaques.

Stations and Maintenance Depots: Replace Energy-consuming Equipment
All THSRC stations and maintenance depots continue to incorporate a number of energy-saving and equipment-upgrading measures, which include replacing traditional chillers, split-type air-conditioners, hydraulic elevators, and lighting equipment to lower the average electricity consumption per passenger trip in stations (not including public electricity consumption in areas shared with TRC) and maintenance depots.
Trains: Energy Saving Driving Program
The THSRC “Train Energy Conservation Team” has implemented the Energy Saving Driving Program since 2010. The Energy Saving Driving Program advocates appropriate use of train traction and brakes to reduce energy consumption during train operations while maintaining safety, punctuality, and comfort. This program reduces equipment wear and extends equipment life, striking an optimal balance between train operations and energy conservation to maximize energy efficiency. As of year-end 2024, we have reduced electricity consumption by 26,909 MWh and carbon emissions by 13,293 tCO2e。
Advanced Energy Conservation Programs
THSRC has initiated “Advanced Energy Conservation Programs” spanning from 2024 to 2030 to replace energy-consuming equipment and incorporate new energy-saving equipment through several phases, thereby generating energy-saving benefits. The seven programs are:
| Project | Summary | Implementations in 2025 | Project Timeline |

Renewable Energy Usage
THSRC has installed solar power generation equipment at all maintenance depots and stations in accordance with government energy transition initiatives. We generated 8,964.01 MWh of solar power in 2024. Total power generated at our four maintenance depots amounted to 6,566.75 MWh, which was all sold to Taipower. Our six stations generated 2,397.26 MWh, of which 176.292 MWh was used by the stations, and the remainder was sold to Taipower.

Regular Review of Energy-Saving Achievements
THSRC has established an Environmental Management Committee which is chaired by the President and composed of the highest-ranking managers of all departments. The Committee supervises THSRC's internal formulations and implementations of environmental policies and goals, convenes quarterly “Environmental Management Meetings” to track progress and achievements on all department environmental projects, and also reviews the energy management promotions and energy savings of all maintenance depots and stations.
Future Prospects
THSRC continues to adopt strategies centered around energy conservation and carbon reduction, energy efficient enhancements, and renewable energy usage in combination with innovative technologies to form systemic and continually improving energy management models. We will continue to uphold our environment responsibilities and social commitments, track progress, improve relevant measures, and work with the government, supply chain, and passengers to promote long-term developments in green transportation as part of our contributions to corporate sustainability, so that THSRC can be an important leader in driving Taiwan towards low-carbon transformations.
Internal Carbon Pricing
THSRC has incorporated internal carbon pricing (ICP) in the corporate carbon reduction governance tools in alignment with one of the Company's six major strategies (“implement carbon reduction actions and fulfill corporate social responsibilities”). We formulated and began implementing ICP mechanisms in 2025, adopting the shadow pricing methodology and referencing the Ministry of Environment Standard Carbon Fee Rate under the Regulations Governing the Collection of Carbon Fees. We set our internal carbon price as NT$300/tCO2e, with implementation scope encompassing Scope 2 greenhouse gas emissions, and regularly review the rationality of our internal carbon prices in consideration of impacts from international and domestic standards, laws, carbon taxes, and carbon prices.
THSRC's ICP mechanisms are applied to all on-site “Advanced Energy Conservation Programs,” which include replacement of energy-consuming chillers, split-type air-conditioners, hydraulic elevators, and lighting equipment (please refer to our Energy Management Plan for further details). Evaluations conducted using our ICP mechanisms estimate that our equipment replacements implemented in 2025 will save 4,193 MWh of electricity, equivalent to 1,987 tons of carbon emissions, which would potentially reduce NT$596,100 in external carbon costs. We aim to continue lowering overall carbon emissions in accordance with our six main strategies.
