本文探讨了澳大利亚奶牛生产的牛奶的碳足迹，并遵循国际乳业联合会和国际生命周期评估标准的共同碳足迹方法指南。主要数据收集和分析来自139个农场代表在澳大利亚的主要乳品地区。研究范围涵盖了2009年7月至2010年6月（2009/2010年）12个月期间从摇篮到农场大门的所有投入和产出。2009/2010年澳大利亚牛奶的平均碳足迹计算为1.11千克二氧化碳当量千克（-1）脂肪和蛋白质校正牛奶。每公斤牛奶的温室气体排放量的差异可以追溯到生产实践的差异。饲料转化效率被认为是减少肠道甲烷排放的最重要驱动因素。还确定了粪肥管理做法的减排潜力。(C)2014爱思唯尔有限公司版权所有。
This paper explores the carbon footprint of milk produced by dairy cows in Australia and follows the common carbon footprint approach guidelines of the International Dairy Federation and the International Standard for Life Cycle Assessment. Primary data were collected and analysed from 139 farms representing the main dairy regions in Australia. The scope of the study covers all inputs and outputs from cradle to farm gate for the twelve month period from July 2009 to June 2010 (2009/2010). The carbon footprint of average Australian milk for 2009/2010 was calculated to be 1.11 kg carbon dioxide equivalents kg(-1) fat and protein corrected milk. Differences in GHG emission per kg of milk produced could be traced back to differences in production practices. The feed conversion efficiency was identified as the most important driver for the reduction of enteric methane emissions. Reduction potentials were also identified for manure management practices.
