Abstract:The decarbonization of copper-processed products has emerged as a critical agenda across the non-ferrous metals, mining, and industrial sectors. Amidst China′s steadily escalating copper demand, the copper industry confronts substantial pressure to mitigate emissions, lagging behind the carbon peaking timeline. To comprehensively assess the greenhouse gas emissions within the copper industry chain, this paper introduces the evaluation system of the carbon footprint of copper products and the research differences at home and abroad, employing a life cycle assessment methodology, unfolds the application process of the carbon footprint evaluation of copper processed products, identifies the industry chain upstream and core links, 3 stages of raw and auxiliary materials, along with their transportation, manufacturing, and subsequent processing stages, and calculates the carbon footprint of the copper-chromium electrical contacts and copper water pumps to be 1.146 kg CO2 e/ piece and 8.526 kg CO2 e/ kg, respectively. The study shows that over 70% of carbon emissions are attributed primarily to the manufacturing of raw and auxiliary materials, and the contribution of transport to the overall carbon emissions (<0.15%) is found to be negligible. The paper also describes the influencing factors, challenges and low carbon recommendations for the carbon footprint of copper processing products, which are important for sustainable development.
