This study analyzed the emission trends of greenhouse gases and the measures against global warming in the New Zealand (NZ) agriculture sector. The NZ agriculture sector has the largest impact for greenhouse gas emission in NZ. Especially, methane emissions from enteric fermentation of sheep, dairy cattle, and non-dairy cattle are significant sources. In accordance with the Kyoto Protocol, NZ’s target is to reduce its greenhouse gas emissions to the level they were in 1990.Measures against global warming in the NZ agriculture sector include reduction in breeding numbers (short-term) and the cutting of greenhouse gas emission factors for livestock through research and development (long-term). However, it is believed that the short-term reduction measure will have a large impact on farmers, such as agricultural income reduction, and the long-term reduction measure will take considerable time to reduce the effects of greenhouse gases.
