The evaluation of the livestock and poultry production of carbon emissions in China based on life cycle assessment
Due to the lack of carbon emission accounting methodology in China's livestock and poultry industry,it is difficult to meet the needs of the evaluation of the livestock and poultry production of carbon emissions in China.The accounting method of this paper referred to the Intergovernmental Panel on Climate Change(IPCC)national greenhouse gas inventory guidelines and life cycle assessment(LCA).The carbon emission rate was based on the Meta-analysis data of domestic livestock and poultry breeding literature research and the relevant data in the Ecoinvent database(GABI 10SOFTWARE),the default value or reference value of the emission factor was re-determined,and the carbon emission accounting method for the whole life cycle of livestock and poultry'feeding-clearing-storage-waste treatment'was constructed.The results show that the carbon emissions of livestock and poultry breeding industry mainly come from manure treatment and energy consumption.For ruminants,the emissions from intestinal fermentation in feeding are the most important sources.Through the error transfer equation analysis,the uncertainty of the method is low,and the method can be realized.
