Occupational safety and health is one of the important components of corporate sustainability. Paying attention to the work safety and health of workers is the responsibility of the company, and it can also get the recognition of employees.
When occupational accidents occurring, it might result in the consequences as follow:

• suspension and fines
  It will increase the cost of production.
• Affect production
  By improving the manufacture to be safer, but it may affect product quality or cost.
• Reputation damaged
  It may lead to the lost of customers.

In order to achieve energy conservation and carbon reduction and respond to mandatory greenhouse gas reductions in advance, CSC started the "Energy Saving Action Plan" in 2005. To date, four phases of the five-year plan have been completed, with each phase successfully achieving its total targets. During the fourth phase (2021-2025), CSC completed 1,308 energy-conservation projects, reaching 295% of the phase's total target. The fifth phase (2026-2030) of the plan will continue to be promoted. Furthermore, the 2025 annual achieved electricity saving rate reached 2.77%, exceeding the requirement of the Energy Administration, MOEA, that "energy users shall achieve an annual and average annual electricity saving rate of at least 1.5% for the period 2025-2028." In 2025, CSC completed 204 energy-saving projects, which saved a total of 949,000 GJ, and saved energy cost by 861 million TWD. These initiatives help mitigate rising energy costs, improve operational efficiency.

CSC implements "hot metal charging technology" in EAF processes to optimize thermal efficiency. By overcoming key technologies—"thermal compensation" and "rapid melting"—CSC surpasses the conventional 30% scrap utilization limit, enabling the development of high-recycled-content low-carbon steel products certified under UL 2809. Based on the benchmark that recycling 1 ton of steel scrap reduces 1.5 tons of CO₂ emissions, CSC translates R&D excellence into low-carbon competitiveness, helping customers reduce product carbon footprints and strengthen competitiveness in green supply chains.
In 2025, high recycled content steel products generated NT$1,728,657,000 accounting for 1.07% of revenue.

In addition, the steel-chemical co-production pilot facility has a carbon capture capacity of 4,900 tons per year. Although currently is a R&D platform, if the scale reaches 100,000 tons in the future, it will capture approximately 125,000 tons of CO₂e, reducing carbon costs and production costs.

• strengthen personnel hazard identification:
  We offer many courses to educate employees and contractors, to understand occupational hazard and accidents, such as “Basic training on safety management of explosion-proof electrical equipment.”
• deepen inspection levels:
  During daily inspections, in addition to observing the work process, workers will also be asked about what hazards in this work process and how to prevent them.
• implement improvement measures
  When an accident occurs, the unit that happened accident should immediately find out the cause of the accident and establish preventive measures based on the cause. In the future, in addition to track whether the preventive measures are still implemented or not. We will also review whether the preventive measures can be improved or not.

CSC mainly implements energy management through the Energy Conservation Committee and control of the energy management system (ISO 50001) to achieve the goals of energy conservation, carbon reduction and continual improvement. The Committee was formed and chaired by VP of Production Division. The Committee has three teams be responsible for energy saving and emission reduction in CSC's plants. The Committee also regularly holds meetings to review the achievement of current targets, share information on energy conservation projects, communicate relevant important topics, bring up appeals or consultations, propose interim motions, and publicize the records of the meeting.

"Increasing scrap use" is one of the key strategies in CSC's carbon reduction pathway. To implement this strategy, CSC focuses on developing high recycled content steel products and advancing circular resource utilization technologies.
By using molten metal technology in electric furnaces, CSC has surpassed the 30% scrap limit for basic oxygen furnaces. CSC continues to develop the RC series (RC12, RC20, RC40, and RC60) high-recycled-content steel products, increasing the proportion of scrap to 60%, obtaining the UL2809 Recycled Content Validation.

In addition, CSC is developing a steel-chemical co-production pilot facility to capture and purify CO and CO₂ from by-product gases in steel plants, supplying it to downstream petrochemical industries as raw materials for chemical synthesis.

• no fatality
• LTIFR of employees is 0.25
• LTIFR of contractors is 0.23

In 2025:
• no fatality
• LTIFR of employees under 0.18
• LTIFR of contractors under 0.28

• The carbon emission was reduced 71,500 tons in 2025, compared to the base year of 2018.
• A pilot plant, costing NT$200 million, was completed in 2022. This is equivalent to 4,900 tons of carbon dioxide.
