External Initiative Participation

With the government encouraging participating external initiatives, Tang Eng Iron Works have taken part in the following activities.

Gender equality promotion program

Respond to and support the gender equality program by ministry of labor, we actively construct female friendly job site, and provide lactation room and child care service, striving for gender equality work environment to ensure the benefits and rights of female workers.

Concentrated burning of spirit money

Spirit money is usually burned in rather small furnace burner or just in the open. Under a condition of ventilation poor, temperature and environment not friendly for spreading, incomplete combustion would produce particulate matter, carbon monoxide, bad smell and dust which would pollute the air. Thus, in response to the concentrated burning of spirit money by Environmental Protection Bureau, Kaohsiung City Government, we collected all the spirit money for ghost festival and take all of it to the recyclables depot to be burned in the furnace with pollution prevention equipment to reduce the air pollution for Kaohsiung city and to maintain the health of the residents and the living quality of the environment.

Establishment of the energy saving goals and implementation plans

Tang Eng Company is committed to pursuing the control measures with high efficiency, high output value, low emission and low consumption, so as to achieve the green effect of saving energy and effectively reducing environmental load. From 2015 to 2024, in coordination with the "Energy Saving Target and Implementation Plan" formulated by the Ministry of Economic Affairs, the average annual energy saving rate should reach more than 1% since the implementation of the plan. The "Demand Response Load Management Measures" and related energy-saving measures (Including recognition for 2023) implemented by Tang Eng Company in 2024 reduced the electricity consumption by about 14,860,280 kWh/year; The 3000KW solar energy field with an investment of NT$ 135 million was also built in July 2023 and connected to the grid. By the end of 2024, the solar energy field generated a total of 3,179,700 kWh of green electricity, which was used by itself to reduce the power purchased. In 2024, the overall energy-saving rate was 11.34%, and the average energy-saving rate from 2015 to 2024 was 6.42%, which reached the "Energy users set energy-saving targets and implementation plans" set by the Ministry of Economic Affairs.

In 2024, process electricity consumption totaled 116.15 million kWh (including solar and other renewable energy). Natural gas usage was approximately 15.9867 million cubic feet, and steam was about 28,730 metric tons. The unit energy consumption indicator for electricity per ton of steel coil production slightly decreased, with electricity intensity at 622.41 kWh/metric ton, a drop of approximately 13.896% compared to 2023. Other energy intensities, such as natural gas and steam, decreased by 3.24% and 2.27% respectively. As steel coil electricity consumption is directly related to capacity and production scheduling, Tang Eng Company continues to diligently seek further energy-saving opportunities, hoping to continuously demonstrate effective results.

In 2024, six energy-saving projects were completed: "Pump Renewal," "Steelmaking HVAC Water System Piping and Management Improvement," "Steelmaking Cooling Water Electrical Control System Upgrade to Variable Frequency Control," "Steelmaking Water Treatment Electrical Control System Upgrade," "Tang Eng Company Rolling Mill Plant Lighting Renewal," and "Rolling Mill Building 2F Central Air Conditioning System Renewal." Specifically: "Pump Renewal" involved replacing old pumps to increase their efficiency to over 74%. "Steelmaking HVAC Water System Piping and Management Improvement" involved piping modifications and management improvements, allowing for the shutdown of one 60HP pump operating 360 days a year, thereby increasing the utilization rate of HVAC water pumps. "Steelmaking Cooling Water Electrical Control System Upgrade to Variable Frequency Control" and "Steelmaking Water Treatment Electrical Control System Upgrade" involved adding variable frequency control to pump electrical control systems, allowing for real-time adjustment of water pressure and consumption based on on-site load changes. "Tang Eng Company Rolling Mill Plant Lighting Renewal" replaced 83 traditional high-wattage light fixtures with highefficiency LED lights. "Rolling Mill Building 2F Central Air Conditioning System Renewal" involved replacing old equipment to improve overall efficiency. The total investment for these six equipment updates and improvements was NT$19.95 million, resulting in an annual saving of 2,111,114.22 kWh of electricity and a reduction of 1,042.89 metric tons of CO2e in greenhouse gas emissions.

Implementation of Voluntary Greenhouse Gas Reduction Plans

Since the announcement of the Climate Change Response Act (Note 1), the Company has continued to cooperate with the control objectives of each stage. Currently, the control is carried out in five-year stage. The first stage of the control target period is from 2016 to 2020. Emissions of the 2005 base year will be reduced by 2%. The second phase of the control target period is from 2021 to 2025. The target is to reduce emissions by 10% compared with the base year. The ultimate goal is to achieve net zero carbon emissions by 2050.

In order to achieve the reduction target of the Climate Change Response Act, the Company cooperates with the Industrial Development Administration of the Ministry of Economic Affairs to implement the Greenhouse Gas Voluntary Reduction Plan every year, and updates and replaces old energy-consuming equipment every year, and submits a report on the current year's energy saving plan and previous year's energy saving performance of the industrial greenhouse gas voluntary reduction platform to the Industrial Development Administration of the Ministry of Economic Affairs every year. The Company has achieved the control targets in the first phase of the temperature control law, and the control targets in the second phase are also being implemented. The Company will continue to work hard and refine various energy-saving plans to continuously achieve control goals.

The Climate Change Response Act (referred to as the temperature control law, which was revised and renamed The Climate Change Response Act on February 15, 2023) is mainly a climate change adaptation strategy formulated in response to global climate change. The purpose is to reduce and manage greenhouse gas emissions, implement environmental justice, fulfill the responsibility of jointly protecting the earth's environment, and ensure the country's sustainable development.
Carbon Reduction and Carbon Fee

In response to the regulations announced by the Ministry of Environment on August 29, 2024, including the “Carbon Fee Collection Regulations,” the “Voluntary Reduction Plan Management Regulations,” and the “Designated Greenhouse Gas Reduction Targets for Carbon Fee Collection Entities,” Tang Eng Company is currently actively promoting a voluntary reduction plan to obtain preferential carbon fee rates and is applying for recognition as a high carbon leakage enterprise to further reduce the impact of carbon fee collection. We continuously improve our processes, replace energy-consuming equipment, increase the use of green energy, and enhance the utilization rate of waste in the circular economy to reduce greenhouse gas emissions. The company will actively implement the above measures. Without submitting a voluntary reduction plan, the annual carbon fee would be approximately NT$36.09 million; however, by applying for high carbon leakage enterprise recognition and using the preferential rate, the carbon fee can be reduced to approximately NT$2.91 million. Going forward, we will continue to promote energy-saving and carbon-reduction measures, with a mid-term goal of reducing emissions by about 47% by 2030 and a long-term goal of achieving net-zero emissions.

Renewable Energy Installation Plan

To align with the government's green energy policy and the potential adjustment of the “Major Electricity Users Clause” in 2026, and based on the company’s energy-saving and carbonreduction roadmap to achieve its goals, Tang Eng Company allocates an annual capital expenditure budget for energy-saving and equipment renewal, and implements accordingly.

To actively promote the development of renewable energy, the company has planned a “Solar Power Plant Construction Project,” to be carried out in two phases:

Phase One was approved by the Board of Directors on December 29, 2021, and the bidding process was completed in August 2022. An actual investment of NT$134.96 million was made to construct a solar power plant with an installed capacity of 3,000KW. The plant was completed and connected to the grid in July 2023. As of the end of 2024, the plant had generated a total of 3.1797 million kWh of green electricity, which was used for self-consumption to reduce the need for purchased electricity.

Phase Two was approved by the Board of Directors on February 24, 2025, and is planned to be constructed in two areas. Area One is located on the east side of the company’s rolling mill plant. The bidding process is expected to be completed by the end of June 2025, with an investment of NT$165.10 million to build a solar power plant with an installed capacity of 3,100KW, scheduled for completion and grid connection by the end of 2026. Once completed, the plant is expected to generate approximately 3.5053 million kWh of green electricity annually, using a self-consumption model, reducing carbon emissions by approximately 1,731.616 tons per year, and saving about NT$21.031 million in renewable energy costs and NT$519,000 in carbon fees annually. Area Two is planned to be located in the company’s parking lot. However, due to pending issues related to partial land acquisition by the Kaohsiung MRT and public parking facilities, a suitable alternative plant site will be identified for planning. Grid connection and power generation are expected to be completed by the end of 2027.

In summary, the company will continue to promote energy-saving, carbon reduction, and the development of renewable energy (or low-carbon power), and plans to complete the installation of solar power plants or related renewable energy facilities with a total installed capacity of 8 MWp (including mandatory capacity) by 2030, using a self-consumption model. This will increase the proportion of renewable energy in total electricity consumption to over 8%, ultimately achieving the goal of net-zero carbon emissions (or carbon neutrality) by 2050.
