Environmental Protection
To pursue the goal of building a green energy homeland, fulfill international carbon reduction commitments, and respond to the rapid changes and challenges in domestic and international political, economic, and energy environments, the government has promoted new energy policies and initiated an energy transformation to drive the development of an independent green energy industry. As global warming accelerates, how to balance environmental protection with energy production has clearly become a significant issue around the world, and it has also underscored the importance of energy transition.
Based on its social responsibility and sustainable management objectives, CT upholds the concepts of energy conservation and carbon reduction, and all employees work together to promote an international standard energy management system and establish energy policies to encourage compliance.

The reasons for the differences in the energy consumption proportion data of each energy system at Century Iron & Steel’s Taoyuan Plant in 2025 compared with 2024 were that projects successively commenced in 2025, and factors such as increased on-site processes and adjustments to plant production lines caused energy consumption to increase. In the future, we will continue to measure data and track the energy consumption of each item and items requiring improvement.
The main energy used by each plant includes purchased electricity and non-renewable fuels (including liquefied petroleum gas, diesel, and electricity). No renewable electricity or renewable fuel was used. According to statistical calculations, the energy consumption of the three plants in 2025 was 37486.37 GJ, representing an 11.0% increase compared to 2024.

Establishment of Management System
In the second half of 2021, CT established an ISO 50001 energy management system at its Taoyuan Plant, and each year it has been verified by a third party certification body.
Through an energy equipment inventory, the energy consumption proportions of each system at the Taoyuan Plant were analyzed, from the air conditioning systems to the lighting equipment, and based on the evaluation results of the prioritized improvement items, the Company’s financial, operational, and business conditions, the selection of energy efficient technologies, and the feasibility of renewable energy use were considered item by item. The sequence for improving the energy efficiency of Company equipment was scheduled, an energy improvement action plan was drafted, and energy management targets for the following year were set accordingly.

Implementation of Energy Saving Measures
In 2025, the Company continued the electricity-saving target established in previous years of “an average annual electricity-saving rate of 1%” and proposed an energy management action plan. In response to issues such as on-site air compressor leakage, the Company worked together with colleagues in the maintenance team to inspect pipelines to reduce pipeline air leakage, and replaced cooling tower motors that had been used for many years, replacing the old with the new to improve efficiency. The energy savings were approximately 2172kWh, and progress was controlled and tracked in accordance with the action plan and the target was completed.
1. Promote energy conservation awareness among employees
Conduct energy conservation awareness sessions for all company personnel. Unplug equipment that will not be used for a long time, and turn off lights and air conditioning when leaving office areas or restrooms.
2. Promote renewable energy power generation equipment
In addition to purchasing renewable energy, solar panel power generation systems have been installed at all plants, generating renewable energy that is zero carbon and free of pollution, thereby indirectly helping to reduce GHG emissions across Taiwan. Additionally, we have also participated in the supply chain for manufacturing wind power generation equipment, offering the people of Taiwan more renewable energy options.
Facing continuously growing production capacity, CT noticed that the energy at its plants was not being fully utilized for production. For this reason, the Company began updating its equipment, gradually phasing out old welding machines and replacing them with models that save energy and increase production capacity. Regular maintenance is performed on all equipment in the administrative buildings of each plant, for example, copiers, computers, air conditioners, and water dispensers, and the lighting tubes in the buildings are gradually being replaced with LED tubes to reduce electricity waste and make more meaningful use of energy.

Item | Implementation |
Newly Purchased Electric Forklift | In recent years, the Yunlin Plant purchased 2 electric forklifts. Compared with diesel forklifts, electric forklifts have less environmental impact because they do not emit exhaust gas and are more environmentally friendly. They also feature higher energy efficiency and conversion efficiency, providing superior steering performance and load handling stability. In addition, electric forklifts have longer operating times and superior battery life. |
Mobile Circumferential Weld Seam Milling Machine (Automated Edge Milling Machine) | Through a highly efficient automated control system, precise load management, and high‑precision machining characteristics, production efficiency is improved and energy consumption is reduced, thereby achieving lower carbon emissions. |
Initiate the Machinery and Equipment Replacement Plan | All welding machines have been replaced with Germany’s top-grade EWM welding machines, improving welding efficiency and reducing energy consumption. Traditional flame cutting machines commonly used for steel plate processing require combustion of gas or acetylene, which not only consumes energy but also causes air pollution and carbon emissions. In addition, the edges produced by flame cutting may not be smooth. Compared with traditional flame cutting machines, the CNC flame cutting machine newly purchased by the Company greatly reduces power consumption and improves production efficiency and machining precision, achieving significant energy savings. The on-site 4-axis drilling machine was too old and was replaced. In 2024, a fully automatic dual axis drilling machine was purchased. The dual spindle model has two spindles with completely independent positioning, improving production efficiency, reducing machine standby time, indirectly lowering energy consumption and achieving higher energy efficiency for energy conservation and carbon reduction. In 2025, the cooling tower motor was replaced to improve usage efficiency and reduce energy consumption, and inspections were carried out on the air compressor pipelines to reduce energy consumption from air leakage. |
4. Implementing Green Procurement
When purchasing new machinery or selecting office supplies, we prioritize environmentally friendly options that offer energy-saving and carbon reduction benefits. For example, purchasing low‑carbon equipment with environmental protection or energy‑saving labels, or purchasing products manufactured by suppliers that reduce packaging waste or have made environmental commitments. Start from the details, implement the concept of sustainability, and reduce environmental impact.
