- Taiwan Mask Corporation (TMC) is not only continuing to replace old equipment with energy-efficient alternatives to reduce energy consumption, but is also planning to utilize renewable energy sources. By the end of 2022, TMC installed solar power generation equipment with a total area of 2,677.5 m² at its FAB One, Two, and Six. In 2023, this installation generated 86,380 kWh of electricity, reducing carbon emissions by 42.76 tons CO2e, which is equivalent to planting 3,563 trees. Note: According to research data from the Forestry Bureau, each additional tree on Earth can reduce carbon dioxide by 12 kilograms per year.
In recent years, in response to the global trend of energy conservation and carbon reduction, TMC has actively implemented measures such as organization and streamlining, industrial waste reduction, and resource conservation. The company has internalized the concepts of energy conservation and carbon reduction, as well as environmental protection, into the work environment. This ensures that employees incorporate these principles into company decision-making, execution, and daily life. TMC continues to implement waste reduction initiatives with the ultimate goal of achieving an environmentally non-polluting environment.
Energy Usage at Operational and Production Sites Primarily Relies on Purchased Electricity
Taiwan Mask Corporation (TMC) primarily relies on purchased electricity as its energy source, with indirect energy usage accounting for approximately 99% of TMC's total energy consumption. Direct energy usage includes diesel and gasoline, which are mainly used for generators, official vehicles, and high-precision machinery. In 2023, following the full-scale production launch of new equipment, TMC's total energy usage reached 127,406.97 gigajoules (GJ), an increase of 16,040.93 GJ compared to 2022. The energy intensity was recorded at 6.38 GJ per kilogram, reflecting an approximate 18% increase from the energy intensity in 2022. Despite the increase in energy usage due to higher production capacity, TMC achieved an energy-saving rate of about 2% in 2023. Since 2017, this has accumulated to a total electricity saving rate of 16%, allowing TMC to meet its short-term energy-saving goals ahead of schedule. This demonstrates the effectiveness of TMC's energy-saving measures and the promotion of energy conservation concepts.
2017-2023 Energy Consumption and Savings
Taiwan Mask Corporation (TMC) is not only continuing to replace old equipment with energy-efficient alternatives to reduce energy consumption, but is also planning to utilize renewable energy sources. By the end of 2022, TMC installed solar power generation equipment with a total area of 2,677.5 m² at its FAB One, Two, and Six. In 2023, this installation generated 86,380 kWh of electricity, reducing carbon emissions by 42.76 tons CO2e, which is equivalent to planting 3,563 trees. Note: According to research data from the Forestry Bureau, each additional tree on Earth can reduce carbon dioxide by 12 kilograms per year.
Taiwan Mask Corporation (TMC) obtained ISO 14064-1:2018 greenhouse gas inventory certification this year. In 2023, TMC's total greenhouse gas emissions amounted to 16,406.53 tons CO2e, with the majority of emissions coming from indirect energy emissions related to electricity usage (Scope 2), which accounted for 99% of the company's total emissions. The remaining direct emissions (Scope 1) included diesel from generators, gas from process cylinders, gasoline and diesel from official vehicles, septic systems, and air conditioning equipment, making up 1% of total emissions. Due to the introduction of new equipment into production in 2023, the emissions intensity was recorded at 0.82 tons CO2e per kilogram, representing an increase of 0.09% compared to the previous year. Additionally, using 2017 as the baseline year, TMC has been comparing the annual reduction rates of greenhouse gas emissions against the baseline. The results indicate that greenhouse gas emissions in 2023 increased by 0.65% compared to the baseline year, slightly reducing the cumulative reduction rate to 22.30%. TMC is actively establishing a greenhouse gas inventory mechanism, conducting regular assessments of greenhouse gas emissions at all facilities, and continuously developing and implementing strategies to reduce energy consumption.

In 2023, the main reduction initiatives were divided into two categories: the installation and replacement of energy-efficient equipment, and the completion of lighting upgrades across the facilities. The total energy savings amounted to approximately 1,195,141 kWh per year, resulting in a reduction of greenhouse gas emissions by about 591.60 tons CO2e. Additionally, Taiwan Mask Corporation (TMC) established an ecological landscape garden of over 1,000 ping (approximately 3,306 square meters) at its Zhunan facility in 2023. This garden provides a comfortable and elegant green environment for employees to relax, with an estimated annual carbon absorption of 2.75 tons. This initiative reflects the company's commitment to promoting green living and enhancing the ecological environment of the technology park, as well as its emphasis on employee well-being and healthy lifestyles.
