Abstract: The Chinese government has planned to hit the carbon emission peak before 2030 and achieve carbon neutrality by 2060. In this case, it is a high demand to reduce emissions, especially greenhouse gas (GHG) emissions. Among them, the livestock industry has been the greatest GHG emission source in agriculture sectors, accounting for 80% of total agricultural non-carbon dioxide emissions. The Emissions Gap Report 2021 has released that the methane emissions can be reduced from fossil fuels and agricultural wastes, further, slowing down global warming in the shortterm. Therefore, a low-carbon livestock industry can also make a great contribution to achieving the carbon neutrality. In this study, a systematic review was made on the agricultural carbon emissions in China, with emphasis on the sources of GHG emissions in animal production systems. Some suggestions were also proposed to reduce the GHG emissions from the livestock and poultry. The carbon emission of the agriculture sector has been the third-largest source of GHG emissions, accounting for about 6.7% of the total emissions in China. The GHG emissions of animal respiration, ruminant intestinal fermentation, and manure are regarded as the direct sources, whereas, the indirect GHG emissions include feed production and processing, the energy consumption of equipment and facilities, as well as animal product processing and transportation. Enteric fermentation has been the largest source of GHG emissions from livestock, according to the global livestock environmental assessment model. Finally, some technologies were also summarized to reduce the GHG emissions from the livestock and poultry. The low-carbon path contained three parts, the source, the process, and the end, according to the whole life cycle of animal husbandry production. Correspondingly, there was a gradual increase in the indirect GHG emissions via energy consumption during the breeding process of livestock and poultry, particularly with the increase in the production and demand of livestock. Moreover, one of the key strategies is necessary to conduct the financial investment and the national incentive mechanism, thereby achieving carbon neutrality. Therefore, this review can greatly contribute to promoting carbon neutrality for the sustainable development of the livestock industry. Four recommendations were made as follows: 1) To monitor the GHG emissions from the livestock industry throughout the entire process and scientifically evaluate GHG emissions and reduction potential of each link; 2) To strengthen the clean production in animal husbandry, including basic and innovative research, further to promote the animal husbandry in a green, low-carbon, and efficient way; 3) To develop the green and low-carbon utilization of manure resources from the livestock and poultry production; and 4) To integrate the modern information technology for the low-carbon emission reduction in the digitally empowered livestock industry.
