Changes in sector emissions estimates since the previous net position update in April 2021 are summarised in the table below.
The largest change is in the contribution from forestry activities. This is mainly due to being able to calculate and include the contribution from forest management activities in pre-1990 forests. New Zealand chose to apply period end accounting for our 2020 target. The forest management reference level, against which forest management activities are accounted for, was calculated for the full period. Forest management activities are subject to fluctuations over time which impacts emissions, and therefore unsuited to annual assessments against a commitment period reference level. Since the 2020 Net Position update has inventory estimates for all commitment period years, the accounting quantity from forest management activities is now able to be quantified for inclusion in the net position.
