Waste Reduction

In response to the international energy price and the rising importance of energy consumption to climate change, it is predictable that efficiency enhancement and effective management of energy will be the major issues for corporate sustainable development, and enhancing energy efficiency is the most economical and effective way.

Yoke introduced the ISO 50001:2018 energy management system in 2022, establishing a systematic management process for continuous improvement of energy performance. In 2024, three energy-saving improvement projects were implemented, achieving a power reduction rate of 3.1% and meeting the target of reducing plant-wide electricity consumption by 1% compared to the baseline indicator. A total of 18 energy-saving improvement cases were implemented, accumulating 81.39 metric tons CO₂e in reductions.

Through the establishment and operation of the carbon reduction team, in 2024 the Company continued to strengthen inter-departmental cooperation and communication, initiated evaluation of real-time monitoring systems to identify potential energy-saving opportunities, and accelerated the calculation of product carbon footprint information. The third factory invested in renewable energy construction, which was completed in the fourth quarter of 2024. As of January 2025, the cumulative total power generation reached 22,744 kWh, achieving carbon reduction of 11 metric tons CO₂e. Additionally, Yoke’s first factory is expected to install a second solar power generation system in the third quarter of 2025, with an estimated power generation capacity of 119kW.

In 2024, Yoke’s annual energy consumption converted to thermal energy was 45,356.86 GJ (10⁹ joules), an increase of 4,005.35 GJ compared to 2023, mainly due to increased energy consumption resulting from additional production machinery and equipment and enhanced production capacity. Energy consumption intensity decreased from 13.78 GJ per million in revenue to 13.03 GJ per million in revenue.

In 2024, process improvements were introduced and under the internal improvement proposal system, the power saving rate significantly increased compared to previous years. Going forward, the company will continue to promote ongoing inventory of energy-consuming equipment and processes, and develop improvement measures. Through the installation of variable frequency equipment or timer devices, the calculated annual energy saving benefit is approximately 318,000 kWh, which can reduce greenhouse gas emissions by approximately 157,247.60 Kg CO₂e (calculated based on the 2023 power emission factor of 0.494 Kg CO₂e/kWh for public power utilities published by the Energy Administration, Ministry of Economic Affairs, in 2024). Over the past 5 years, the company has also achieved the Ministry of Economic Affairs’ target of 1% annual power saving for energy users.
