GHG Inventory

Greenhouse Gas Inventory and Disclosure

Since 2022, Daxin has conducted greenhouse gas inventories in accordance with ISO 14064-1:2018. The inventory boundary is consistent with the Company's financial reporting scope, covering headquarters, the Chungke plant, and the Chungkang plant. Subsidiaries are excluded due to the absence of actual operational activities. The operational control approach is used to quantify Scope 1, Scope 2, and Scope 3 emissions, with annual third-party verification conducted and verification statements obtained.

• Unit: metric tons CO₂e.

Organizational Operational Emissions (Scope 1 and Scope 2)

According to the 2025 greenhouse gas inventory, Scope 2 emissions (purchased electricity) account for approximately 90% of total operational emissions and represent the primary emission source. The Company reduces Scope 2 emissions through energy efficiency improvements, on-site solar PV systems, and green power purchase agreements.
Scope 1 emissions (direct emissions) account for approximately 10% of total emissions, primarily from HFC refrigerant leakage in process cooling and refrigeration systems. Given the high global warming potential (GWP) of HFCs, the Company references the COP28 Global Cooling Pledge and relevant regulatory frameworks in Europe and the United States to progressively adopt low-GWP refrigerants, combined with equipment management measures to reduce direct emissions and ensure alignment with mid- to long-term carbon reduction targets.
