10.2 Recalculations in response to the review
process and planned improvements
10.2.1 Response to the review process
The recommendations from the review of the 2013 Inventory submission (UNFCCC,
2013) and New Zealand’s responses are included below in table 10.2.1. The Expert
Review Team (ERT) report for the 2014 Inventory submission was not published in time
to be taken into account for this submission.

Expert review team
recommendation (including report
paragraph number)
Para 38. Review the carbon dioxide
(CO 2 ) emission factor (EF) for solid
fuels and report the findings.
Para 40. Disaggregate liquefied
petroleum gas from natural gas
liquids.
Para 46. Improve the transparency of
the information on the CO 2 and CH 4
EFs used for geothermal energy and
on the consistency of the time series,
and reassess the country-specific
unique emission factor when more
data becomes available.
Para 49. Include additional
information on how the CO 2 EFs
used for solid fuels were calculated
and the applicability of total solid
fuels used in New Zealand across the
entire time series.
Para 23. Include more background
information on each recalculation
with a view to enhancing the
transparency of the GHG Inventory.
Para 26. Apply greater rigour in its
investigation of underlying reasons
for the differences over the time
series, especially for the later years
when it is greater than 2.0 per cent.
Para 29. Addresses the
inconsistency between CRF table 1.A
(b) and table 1.C
Para 31. Clarity where emissions
from methanol production are
reported.
Para 32. Investigate the
appropriateness of the 2007 EF for
use in the earlier years of the
Inventory time series, and report
thereon.
Para 34. Report estimates of
emissions from venting and flaring
New Zealand response
Work in progress. This will be
implemented in future submissions. Note
that the EF for solid fuels is well within the
IPCC range and is only 2 per cent below
the IPCC medium.
Work in progress. New Zealand will
provide further information in the future
Inventory submissions.
Work in progress. New Zealand will
report the information when more data
becomes available in the future Inventory
submissions.
Work in progress. New Zealand will
report the information when more data
becomes available in the future Inventory
submissions.
Completed. Recalculation explanations
have been entered into the 2014 CRF
tables where applicable.
Completed. New Zealand has undertaken
a systematic and rigorous investigation
into differences between the reference and
sectoral approaches. Explanations of
differences have been reported in the
2014 Inventory submission. Sources of
differences have been identified for a more
accurate and useful comparison with the
reference approach.
Completed. This is addressed in section
3.2.2 of the 2014 Inventory submission,
and also in section 3.3.8 of the 2014
Inventory submission.
Completed. This has been addressed and
the reporting of emissions from methanol
production now follows IPCC guidelines.
Completed. The emissions factors for
solid fuels have been revised for the time
series 1990–2007. Values are now
calculated by interpolation between 1990
and 2008.
Completed. New Zealand has included
this information in the 2014 Inventory
