Greenhouse Gas Emissions
Indicators and Targets
Greenhouse gas emissions are a major cause of climate emergencies, and corporate greenhouse gas management is one of the key issues of concern to all stakeholders.
Since 2023, our company has established a greenhouse gas inventory standard mechanism in accordance with ISO14064-1 and the Greenhouse Gas Inspection Guidelines of the Environmental Protection Administration, Executive Yuan, and regularly inspects the greenhouse gas emissions of all plants in the company every year.
The 2024 Greenhouse Gas Inventory results for Scope 1 and Scope 2 have been verified by Crowe (TW) CPAs under limited assurance, with an assurance report issued in accordance with Standard on Assurance Engagements 3410.

Note 1: Based on emissions statistics for 2023 and 2024
Note 2: Greenhouse gas emission intensity = Total emissions (metric tons of CO₂e ) / million-tonne turnover; turnover is sourced from the consolidated profit and loss statement of the annual report.
Note 3: The Category III emissions inspection was not carried out in 2023, therefore no relevant data is available for that year.
Note 4: The scope covers the entire Arizon Group, including the Taipei Operations Headquarters, Taipei Manufacturing Plant, Arizon China, Arizon Japan, Arizon USA, and Arizon Vietnam.

To better understand other indirect greenhouse gas emissions, identify major emission sources, and develop effective carbon reduction strategies, Arizon plans to calculate key categories of other indirect greenhouse gas emissions in the future by referencing ISO 14064:2018, the Environmental Protection Administration’s Carbon Footprint Database, and the greenhouse gas accounting technical documents issued by the World Business Council for Sustainable Development (WBCSD).
The Company’s greenhouse gas (GHG) emissions within the assured scope for the period from January 1 to December 31, 2024 are as follows:

The Company defines its organizational boundary for greenhouse gas accounting using the operational control approach, which includes the parent company and its subsidiaries. Under this approach, the Company accounts for 100% of the greenhouse gas emissions from operations that it owns and controls.
Reduction measures
Our company is a committed enterprise to participate in science-driven carbon reduction initiatives. STBi's carbon reduction targets are:
Using 2024 as the base year, we commit to reducing total greenhouse gas emissions in Categories I and II by 42% by the near-term target year of 2035, while reducing Category III economic intensity emissions by 66.3%. In addition, for the emission reduction actions in Category III carbon emissions, we will require suppliers to gradually provide information on the carbon footprint of their products or carbon emission data related to production as a reference for future carbon emission management in Category III.
To achieve its emission reduction targets, the Company regularly monitors and tracks progress through its Sustainability Committee. In addition to continuously strengthening energy conservation and carbon reduction performance at the manufacturing stage, the Company is also actively investing in renewable energy generation, including the installation of solar panels and other facilities, to enhance overall carbon reduction effectiveness through diverse means. Furthermore, the Company is implementing carbon reduction measures across various aspects, including material design and selection, local supplier procurement strategies, energy-efficient production, and green transportation, based on a product lifecycle approach. The Company will continue to negotiate the purchase of renewable energy to achieve its carbon reduction goals at each stage. Through these carbon reduction measures, carbon emissions in Category I and Category II will have been reduced by 4.2% in 2025 compared to the base year.
