Environmental Protection：
Greenyn Biotechnology continues to integrate environmental sustainability into its business operations and risk management. The Company addresses climate change, nature, energy, water resources, and waste through resource efficiency improvements and environmental management measures to reduce the environmental impacts of its operations.

The Company continues to identify climate-related risks and opportunities in line with the TCFD framework and officially became a TCFD supporter in 2023. In 2025, Greenyn Biotechnology further introduced the TNFD framework to progressively assess its dependencies, impacts, risks, and opportunities related to nature across its operations and value chain, incorporating nature-related issues into environmental sustainability management and future strategic planning.
 

• Climate Change Management

Since 2022, Greenyn Biotechnology has referenced the TCFD framework to identify climate-related risks and opportunities across governance, strategy, risk management, and metrics and targets, while using greenhouse gas inventories to monitor major emission sources.

In 2025, total GHG emissions were 840.56 tCO2e, and GHG emissions intensity was 0.9183 tCO2e per NT$ million of revenue, representing a decrease of approximately 2.4% from 2024.
 

Categories of Emission Sources	2023	2024	2025
Scope 1 direct emissions	50.97	94.56	118.17
Scope 2 Indirect emissions from purchased electricity	644.07	727.42	722.40
Total	695.05	821.98	840.56
Emissions intensity (tCO2e/million dollars in revenue)	0.8683	0.9413	0.9183
		Unit:	tCO2e

Note: Statistics cover Plants 1–3 and the headquarters; water expenses for the north/south offices and logistics center are included in rental fees and thus excluded.
 

• Energy Management

Greenyn Biotechnology continues to implement energy conservation and efficiency measures across R&D, production, and equipment management. In line with the development of the new facility, planning and tendering for solar panel installation were completed in 2025, laying the groundwork for future renewable energy deployment.

Total energy consumption in 2025 was 6,596.37 GJ, with electricity remaining the primary energy source.

Energy Consumption

Category (unit: GJ)		2023	2024	2025
Direct Energy	Natural gas energy consumption	232.93	843.08	1,011.96
	Fuel energy consumption	31.35	53.86	50.23
	Diesel energy consumption	56.17	64.03	46.89
Indirect Energy	Electricity consumption	4,693.64	5,524.72	5,487.28
Total energy consumption		5,014.10	6,485.69	6,596.37

 

• Water Resource Management

Water is an important operational resource for Greenyn Biotechnology’s manufacturing, production, and R&D activities. The Company continues to improve water use efficiency through water management, process improvements, and recycling and reuse measures.

In 2025, total water withdrawal was 6.166 million liters, recycled and reused water reached 0.680 million liters, and water use intensity decreased to 0.00674 million liters per NT$ million of revenue.

• Waste Management

Greenyn Biotechnology continues to reduce waste generation and resource consumption through process improvements, resource reuse, and the digitalization of administrative processes, while implementing waste sorting, collection, transportation, and treatment in accordance with applicable regulations.

No hazardous industrial waste was generated in 2025. General industrial waste was appropriately managed through recycling, reuse, incineration, and other treatment methods.

Statistics of Industrial Waste Processing at Greenyn

Period	Waste Processing Method	Recycling	Reuse	Incineration	Other	Total
2025	General industrial waste (ton)	4.23	14.4	83.23	19	120.86
	Hazardous industrial waste (ton)	0	0	0	0	0
	Proportion of processing method (%)	3.5%	11.9%	68.9%	15.7%	100%
2024	General industrial waste (ton)	2.4	14.4	83.03	5	104.83
	Hazardous industrial waste (ton)	0	0	0	0	0
	Proportion of processing method (%)	2.3%	13.7%	79.2%	4.8%	100%
2023	General industrial waste (ton)	3.6	12	43.43	19.4	78.43
	Hazardous industrial waste (ton)	0	0	0	0	0
