This report is the second of two reports commissioned by He Waka Eke Noa, as part of their five-year programme to implement a framework by 2025 to reduce agricultural greenhouse gas emissions and build the agriculture sector's resilience to climate change.
In order to achieve these milestones, a draft set of minimum specifications for methods was developed by the Emissions Reporting Workstream of He Waka Eke Noa. In addition, a set of recommendations on presentation of the results were developed.
An initial report was commissioned to assess the performance of seven models and calculators capable of calculating biological greenhouse gas (GHG) emissions against the set of draft minimum requirements for methods, and the recommended presentation of results. A further four models are assessed in this report. Three of these models were assessed in 2021 and an additional model was added to the updated report in 2022.
Although the He Waka Eke Noa process has now been wound up, this report provides a useful way for farmers, advisors, processors, regulators and others to understand the capabilities and limitations of the assessed GHG tools.
