New Zealand agriculture is required to achieve a 10% reduction in its methane emissions by 2030. I mentioned in a recent article that methane emissions per kg of New Zealand lamb meat are estimated to have decreased by 31% since 1990/91. These biological efficiency gains then flow through directly to the same efficiency gains in terms of lower methane emissions per unit of product. I then looked at what would happen if Milksolids production per kg of liveweight increased from the 2019/20 figure of 0.8 kg of Milksolids per kg liveweight to 1.0 kg Milksolids for each kg of liveweight. Bringing this all together, achieving 10% reduction in methane emissions by 2030 looks feasible but challenging.
