Download Reducing uncertainty of the enteric methane emissions inventory

The current estimate of uncertainty in the national enteric methane emission inventory is far greater than that of other countries. The objective of this review was to quantify the variability of CH4 yield and other factors, then use the determined variability of CH4 yield to re-assess the uncertainty of the methane emission inventory, and finally compare the NZ inventory uncertainty analysis with Australia, Ireland and the USA to make recommendations for a NZ inventory process.
