纺织服装原材料阶段碳足迹评价及碳减排措施——以棉花为例

Carbon footprint evaluation on raw materials stage of textile and garment carbon emission reduction measures:In case of cotton

纺织服装产品的碳足迹研究一直以来多集中在对工业加工环节的探讨,对其原材料的获取阶段的碳足迹研究则相对较少.作为产品的全生命周期碳足迹的探讨,原材料阶段的碳足迹也应该加以重视.鉴于棉纤维是我国产量最大的天然纤维,重点探讨棉纺织品原材料--棉纤维的碳足迹,在理解生命周期评价理论的基础上,基于PAS2050指南规范,确定棉花获取的碳足迹评价,在界定系统边界的前提下,给出了各环节碳足迹的计算方法,最后,提出纺织服装产品原材料阶段的碳减排措施.

The study about carbon footprint of textile and garment products is mostly concentrated in the industrial processing sector, and the research on carbon footprint of its raw material acquisition phase is relatively small. As a full life-cycle carbon footprint of the product, the raw material stage should also pay attention. Since the cotton fiber is China′s largest production of natural fiber, the carbon footprint of raw materials for cotton textile-cotton fiber is discussed. Based on the understanding of the life cycle assessment theory, in view of PAS2050 Guide specification, the carbon footprint evaluation of cotton is determined. Under the premise of defined system boundaries, the method to calculate the carbon footprint of various sectors is given. At last, the carbon emission reduction measures for the raw materials stage of textile and garment products are proposed.
