Abstract: The non-ferrous metal industry is a high-energy-consumption and high-emissions industry that is fundamental to the national economy. As a crucial component of China’s low-carbon transformation, it plays a vital role in achieving carbon peak and carbon neutrality. Achieving green and low-carbon development in the non-ferrous metal industry is essential for prolonging the time for reaching carbon peak, and analyzing the development path of non-ferrous metal enterprises towards this goal is of practical significance. Employs accounting analysis of historical greenhouse gas emissions data from a non-ferrous joint enterprise, and uses scenario analysis to create three future development models. Predicts the peak greenhouse gas emissions of the non-ferrous metal joint enterprise under three scenarios: baseline, moderate, and peak. The carbon reduction potential accounting method is then used to discuss energy structure adjustment, industrial transformation and upgrading, and carbon reduction trends under the path of energy saving and carbon reduction, such as process energy saving, potential tapping, electrification level improvement, and comprehensive resource utilization. The results indicate that greenhouse gas emissions from the non-ferrous metal joint enterprise will peak in 2028 under the peak scenario, and the carbon emission growth rate will decline year by year after 2028 under the moderate scenario. However, the baseline scenario cannot achieve a carbon peak. Based on the actual situation of the enterprise, proposes main paths and measures to achieve carbon peak, provides a methodology and reference for the non-ferrous metal industry to reach carbon peak goal.
