Environmental Safety Value
GHG Inventory
In 2025, total Scope 1 and Scope 2 emissions amounted to 5,574.66 metric tons of CO₂e, an increase of 192.13 metric tons of CO₂e compared with 2024. The increase was primarily attributable to the inclusion of Factory 3 in the inventory boundary beginning in 2025, as well as the addition of production machinery and increased production capacity, which resulted in higher energy consumption. Yoke continues to inventory energy-consuming equipment and improve manufacturing processes, with greenhouse gas emission intensity decreasing compared to 2024 (from 1.55 to 1.45 metric tons of CO₂e per NT$1 million in revenue).
Energy Management
Since 2022, YOKE has implemented the ISO 50001:2018 Energy Management System, establishing a systematic management framework to continuously improve energy performance.
In 2025, Yoke's annual energy consumption converted to thermal energy was 44,905.9 GJ (109 joules), an decrease of 450.88 GJ compared to 2024, mainly due to increased energy consumption resulting from additional production machinery and equipment and expanded factory operations. Due to continuous energy-saving initiatives, energy intensity decreased from 13.02 GJ per NT$1 million in revenue to 12.41 GJ per NT$1 million in revenue.
