Introduction

As sustainability becomes a global priority, organizations are expected to better understand and manage their greenhouse gas (GHG) emissions. Carbon footprint verification helps quantify emissions, identify key sources, and support long-term reduction planning. As part of its ESG commitment, AEWIN conducts annual carbon footprint verification to ensure transparent reporting and responsible environmental management.

Carbon Footprint Verification

Carbon footprint verification involves identifying, measuring, and reporting the greenhouse gases (GHGs) emissions generated by an organization’s activities. This process not only helps identify the sources of emissions but also sets a foundation for developing effective reduction strategies. For AEWIN, it aligns with the company’s ESG roadmap, reinforcing its commitment to sustainability and responsible governance.

GHS Verification Methodology

AEWIN’s carbon footprint verification for the year 2025 follows the standards of ISO 14064-1:2018. It ensures comprehensive documentation and accurate reporting of all GHG emissions within the company’s operational boundaries covering its headquarters, factory, and warehouses in New Taipei City, Taiwan.

The emissions are categorized as:
–        Category 1 (Direct Emissions): These direct emissions come from fixed and mobile combustion sources, such as company vehicles and on-site fuel usage. AEWIN also accounts for emissions from equipment like fire extinguishers, refrigeration units and CO2 cylinder (for soda water machines), providing a complete picture of its direct GHG impact.
–        Category 2 (Indirect Emissions): Purchased electricity source from Taiwan Power Company is the primary of indirect emissions.
–        Category 3 (Indirect Emissions): It covers employee commuting and business travel.
–        Category 4 (Indirect Emissions): Generated by the use of products or services by the organization, it involves upstream emissions including purchased electricity and water resources.

Carbon Footprint Calculation
AEWIN used the following standard formula based on ISO 14064-1:2018 and 2021 IPCC Sixth Assessment Report (AR6):
GHG Emissions = Activity Data × Emission Factor × Global Warming Potential (GWP)
–        Activity Data represents the quantity of an activity, such as the amount of fuel burned, or a product produced.
–        Emission Factor is the amount of greenhouse gas emitted per unit of activity, e.g., the amount of CO₂ produced per liter of gasoline.
–        Global Warming Potential (GWP) is a measure of the relative warming impact of a greenhouse gas compared to carbon dioxide. For the values of GWP, AEWIN applied the latest IPCC AR6 standards.
By this calculation, the total greenhouse gas emissions could be determined in terms of carbon dioxide equivalents.

Statement of AEWIN’s 2025 Carbon Footprint

The results of AEWIN’s carbon footprint verification reveal critical insights into the company’s environmental impact. For the period from January 1, 2025, to December 31, 2025:

–        Direct GHG Emissions (Category 1): AEWIN’s direct GHG emissions amounted to 39.4086 metric tons of CO2, accounting for 2.89% of the company’s total emissions.

–        Indirect GHG Emissions (Category 2+3+4+5): Indirect emissions totaled 1326.2019 metric tons of CO2, making up 97.11% of the overall emissions.

This comprehensive breakdown helps AEWIN understand the relative impact of different activities and identify potential areas for future improvement.

Conclusion

AEWIN conducts annual carbon footprint verification as part of its commitment to ESG transparency and environmental responsibility. By establishing a comprehensive and certified GHG inventory, the company gains a clearer understanding of its emission sources and the opportunities for improvement. Through continuous monitoring and responsible operational management, AEWIN aims to deliver sustainable value to both the environment and society.
