New Zealand is required to maintain an inventory of its GHG emissions as part of its obligations under the United Nations Framework Convention on Climate Change (UNFCCC). The inventory is an annual report of all human-induced emissions and removals of GHGs in NZ. The first formal inventory was submitted in 1994 as part of New Zealand’s first national communication to the UNFCCC, and annual reporting started in 1998. The inventory is coordinated by the Ministry for the Environment (MfE), while MPI produce estimates of agricultural GHG emissions and supports forestry sink estimates particularly from planted forests. While a national inventory uses some assumptions and generalisations to estimate emissions from different sources, it is designed to reflect as much as possible the eventual emissions reductions in agriculture that could arise from current mitigation research.

For more information about estimating emissions for a national inventory, see the NZAGRC-PGgRc factsheet: Reducing New Zealand’s agricultural greenhouse gas emissions: How we measure emissions (pages 11-14).

There is funding to support research on agricultural greenhouse gas emissions reporting, and projections of future emissions from land use. Direct investment in inventory projects comes from MPI and all projects have a domestic focus to ensure New Zealand can continue to comply with UNFCCC rules.
