It has often been claimed that non-carbon dioxide greenhouse gases (NCGGs), such as methane, nitrous oxide and fluorinated greenhouse gases, are significant contributors to climate change. Here we nvestigate emission estimates of methane and nitrous oxide from livestock and poultry production, which is recognized as a major source of those NCGGs, in Korea over the period of 1990 through 2010. Based on the data on livestock and poultry populations, emission estimates of methane and nitrous oxide are first derived based on the Tier 1 approach. Then, the Tier 2 approach is adopted to obtain emission estimates of methane and nitrous oxide from cattle, which are known to be the largest sources of these NCGGs and account for about 70% of emissions from livestock and poultry in Korea. The result indicates that the Tier 2 estimates of methane and nitrous oxide emissions from enteric fermentation and manure management are significantly different from the Tier 1 estimates over the analysis period.
人们常常声称，甲烷、一氧化二氮和含氟温室气体等非二氧化碳温室气体是气候变化的重要促成因素。在此，我们调查了1990年至2010年期间韩国畜禽养殖产生的甲烷和一氧化二氮排放估算情况，畜禽养殖被认为是这些非二氧化碳温室气体的主要来源。基于畜禽数量数据，首先采用一级方法得出甲烷和一氧化二氮的排放估算值。然后，采用二级方法来获取牛产生的甲烷和一氧化二氮排放估算值，牛是这些非二氧化碳温室气体的最大来源，约占韩国畜禽排放的70%。结果表明，在分析期内，肠道发酵和粪便管理产生的甲烷和一氧化二氮排放的二级估算值与一级估算值存在显著差异。
