Latest updates to the EAP
The AIA Environmental Accounting Platform (EAP) is regularly updated to reflect changes to the National Greenhouse Accounts emissions factors, based on recommendations from the EAP Technical Advisory Panel . The Panel, made up of leading Australian experts in GHG accounting, emissions reductions, soil carbon management and climate science, ensures the AIA EAP remains on the cutting edge of science and research and stays up-to-date with relevant standards.

This update includes emissions factor changes as per the below. In addition, this update means the EAP is already consistent with the very latest versions of the GAF Tools - which will be published on the Primary Industries Climate Challenges Centre website shortly.
Emissions Factor ChangesThe two emissions factor changes that are now live in the EAP are:
The crop residue emission factor has been updated to 0.503%
The nitrous oxide emission factors for inorganic fertiliser have been updated to:
Production system Irrigated pasture
Irrigated crop
Non-irrigated pasture
Non-irrigated crop
Sugar cane
Cotton
Horticulture
Emission factor (a) (Gg N2O-N/Gg N)
0.0059
0.007
0.0018
0.0041(b)
0.0199 (c)
0.0053
0.0064
(a) Based on (Grace, et al. 2023)
(b) Weighted EF assuming 77 percent of non-irrigated crops occur on low rainfall areas. Low rainfall EF=0.0029 and high rainfall EF=0.008. The threshold between low and high rainfall areas is annual rainfall = 600mm.
(c) Based on Scherbak and Grace (2014).
