Organizational and Product Carbon Footprint Assessment (Headquarters and Construction Sites)：

Ancang actively enhances corporate environmental and energy efficiency performance, reduces environmental impact, continuously optimizes system operation management and internal operational carbon reduction, and implements an organizational greenhouse gas verification system in accordance with the company's mid-term sustainable development goals. Through mandatory statistics and improvements, we progressively achieve the target of reducing greenhouse gas emissions, demonstrating our company's commitment to environmental protection. Furthermore, the company regularly sends personnel to participate in external training courses to obtain the latest carbon accounting information and meet the expectations of the Financial Supervisory Commission and the general public.
