[Objective] With the establishment of the food security strategy and the dual carbon goals, examining the carbon emission patterns of the livestock industry—the main contributor to agricultural carbon emissions—is of great value for the supply of livestock products in the future and the establishment of a systematic carbon emission reduction mechanism for agriculture and other industries. [Methods] In this study, we estimated the carbon emissions of the livestock industry in 31 provinces of China from 2000 to 2020 using the life cycle approach. The carbon emissions of China’s livestock industry was divided into three stages—a highly fluctuating rising stage, a sharp falling stage, and a slowly rising and then falling stage. [Results] It was found that (1) from 2000 to 2020, the total carbon emission of China’s livestock industry fluctuated between 638.6458 million ton to 795.2947 million ton with an average annual growth rate of 0.95%, and 3 stages characterize it. That is high fluctuation rise, precipitous fall, and slow rebound and fall back. (2) The spatial pattern of carbon emissions from China’s livestock industry has changed significantly, gradually forming a significant carbon emission belt of the livestock industry extending from the northeast to the southwest. (3) The production efficiency was high in southern China and low in the north. Most regions with high economic efficiency were in the southeastern coastal areas or grain-producing regions in central and western China. The economic and production efficiencies of animal husbandry in Tibet, Qinghai, and Xinjiang were low. (4) The carbon emissions of the livestock industry across China were at a relatively equitable level. The contribution in the overall Gini coefficient is as follows: the contribution of inter-regional differences > the contribution of intra-regional differences > the contribution of hypervariable density. [Conclusion] Both in terms of economic efficiency and production efficiency, carbon emissions from China’s livestock industry are generally in a fair state, but the emission efficiency in areas such as Qinghai and Tibet is still at a low level. Differentiated measures should be taken to improve the efficiency according to the development characteristics of specific regions. |
