Taking Tianshui Huaniu apple as the research example, we draw a conclusion that carbon footprint in a kilo of Huaniu apple is 0.069 824 9 kg Ce by calculating carbon footprint in Huaniu apple LCA, that is, CO2 emissions in Huaniu apple LCA is 0.256 024 6 kg. And the discharge hot spots are fertilizing and power consumption in producing, which account for 52.20% and 29.82% of the total respectively. In the end, this paper proposes to build Huaniu apple carbon labeling on the basis of domestic carbon labeling research developments. Ke...
