Abstract: The detrimental effects of climate change require countries and regions to use green and low-carbon strategies as the basis for economic development. Agriculture and livestock industry have become among the main industries that emit greenhouse gases. Yongchang County is suitable for the development of large-scale livestock operations due to its unique geographical advantages. However, the potential effects of the carbon dioxide emissions and the environmental impact potential of various farming and animal husbandry farming models on human well-being need to be considered. The purpose of this paper is to use life cycle assessment (LCA) to comprehensively assess the carbon emissions and environmental impact of circular agriculture and livestock industry and to provide important decision support for the establishment of a low-carbon circular agriculture and animal husbandry model. It uses a 75 kg dairy sheep as a functional unit to combine a noncircular farming model (S1) and a circular farming model (S2). The degree of carbon emissions, environmental impact potential and human well-being environmental effects are compared. The results show that the carbon dioxide emission of S1 is 891.3 kg, while the emission of S2 is 647.3 kg, and the difference between the two is 244 kg. S2 has a lower global warming potential than the S1 model; hence, the S2 model, which uses biogas for power, has lower carbon emission than the S1 model. From the perspective of human well-being and environmental benefits, the S2 model of biogas power generation is a low carbon emission and high-benefit model. The biogas power generation model lays the foundation for the realization of the “peak carbon dioxide emissions” and “carbon neutralization” goal, strengthens ecological protection on the north side of the Qilian Mountains and improves human well-being in the region.
