Goals and achievement
YOKE’s first step towards climate change response began with our risk assessment and inventory of GHG emissions. The risk assessment enabled us to gain a preliminary understanding of the risks involved. At the same time, we sought to establish a functional set of performance indicators that we can rely on for climate change mitigation and adaptation through a standardized collection procedure of quantified data taken from our GHG inventory.
GHG Inventory
The total emissions of Scopes 1 and 2 in 2022 were 7,672.50 tCO2e as verified by third-party assurance. With 2019 as the base year, total 2022 emissions increased by 42.36% or 2,283.01 tCO2e. Scope 1 emissions included by 42.88% or 95.47 tCO2e, and Scope 2 emissions by 42.34%% or 2,187.53 tCO2e. Carbon emissions increased mainly because of the increased energy consumption due to the increased factory utilization rate after the global economic recovery, the increased self-production rate, and factory equipment expansion. The 2022 intensity GHG emissions was 2.10 tCO23/NTD million revenue.
Additionally, we inventoried Scope 3 emissions for the first time in 2021. Through assessment in compliance with ISO 14064-1:2018, we included the upstream emissions from “purchased goods” in the inventory. The 2022 emissions were 1,185.82 tCO2e.

---|---|---|---|---|
Operation Site | Factory 1, Factory 2 | Factory 1, Factory 2 | Factory 1, Factory 2 | Factory 1, Factory 2 |
Scope 1 (direct greenhouse gas emissions and removal) | 222.68 | 187.35 | 193.54 | 318.15 |
Scope 2 (indirect greenhouse gas emissions from imported energy) | 5,166.81 | 4,342.92 | 4,811.26 | 7,354.34 |
Scope 1 and 2 combined | 5,389.49 | 4,530.27 | 5,004.80 | 7,672.50 |
Greenhouse emission intensity (metric tons of CO2e/million NT$) | 1.75 | 1.91 | 1.77 | 2.10 |

Note 1: Scopes 1, 2, 3 of the unit: metric tons of CO2e
Note 2: The greenhouse inventory was implemented in accordance with ISO 14064-1:2018 version, and SGS has been commissioned to conduct the third-party verification.
Note 3: Category 2 emissions are attributed to electrical power, and in 2022 we adopted the latest emission factor of 0.509 tCO2e/GWh as published by the Energy Bureau in 2021.
Note 4: For fuel and refrigerant emission coefficients, we referred to Emission Factor Table 6.0.4 from the research summary of greenhouse gas emissions published by the Environmental Protection Agency, Executive Yuan.
Note 5: We adopted the global warming potential as stated in the IPCC AR5 for the GWP in 2013.
