- In 2022, the completion of solar power generation equipment is projected to yield an annual output of 356 kWh, equivalent to planting 1,282 trees.
- In 2022, the implementation of four energy-saving projects resulted in a total energy savings of approximately 2,289,804 kWh/year. This corresponds to a greenhouse gas emission reduction of approximately 1,133.45 tons of CO2e, equivalent to the carbon absorption capacity of three Daan Forest Parks for a whole 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
In 2022, despite an increase in factory production capacity, TMC experienced a decrease of approximately 2% in energy intensity compared to 2021. Taking 2017 as the baseline year, TMC has achieved an accumulated energy savings rate of about 14% by 2022. This effectively demonstrates the success of TMC's energy-saving measures and the effective promotion of energy-saving principles within the company.
2017-2022 Energy Consumption and Savings
TMC has been actively replacing old equipment with energy-efficient ones to reduce energy consumption while plans to adopt renewable energy are underway. By the end of 2022, solar power generation facilities with a total area of 2,677.5 m2 will be installed at TMC's Fab 1, Fab 2, and Fab 6 in Taiwan. It is expected to generate 356 kWh of electricity, serving as a measure for TMC to address and adapt to the operational impacts of climate-related risks in the future.
In 2022, TMC's total greenhouse gas emissions amounted to 15,528.89 tons of CO2e. The primary contribution came from indirect energy emissions related to electricity usage (Scope 2), accounting for 98% of the company's total emissions. The remaining 2% comprises direct emissions (Scope 1) from sources such as diesel generators, process steel cylinders, government vehicle fuels (gasoline and diesel), septic tanks, and air conditioning equipment.
