Reporting software:
Requirements, challenges and opportunities
(1) https://www.ipcc-nggip.iges.or.jp/software/index.htmlCRTs for GHG Inventories │Lorenz Moosmann│CCXG│ 25 November 2020
Opportunities
Use CRF reporter
concepts, but update
technology
Take into account the
experience of CRF
reporter users
(interface, import etc.)
Arrange for direct
import from the IPCC
Inventory Software (1)
Requirements
Create tables and
forward data to the
UNFCCC secretariat
Reliable software
Sufficiently easy to
use
Available in time for
first reporting under
the transparency
framework
Challenges
More Parties
Many new users
More diverse
inventories
Higher load of data to
be processed;
possibly peak times
close to the reporting
deadline

Thoughts on the structure of CRTs (I)
● Hierarchy of tables
To ensure transparency, it is particularly important to report sectoral background
information, i.e. activity data and emissions per category.
Sectoral background information is generated during inventory preparation.
The availability of this information is key for the technical expert review.

Thoughts on the structure of CRTs (II)
● Accommodating for different configurations of national inventories
CRTs for GHG Inventories │Lorenz Moosmann│CCXG│ 25 November 2020
Common reporting tables
Provide for options to add categories
under “other”
Options to use notation keys
Parties may have additional categories in
their inventories
There are no entries for certain
categories and/or certain gases
Examples
from current
CRF tables

Use of inventory information
CRTs for GHG Inventories │Lorenz Moosmann│CCXG│ 25 November 2020
● CRTs are one specific way of providing inventory information.
● They are a central element of the transparency framework – as
templates for electronic reporting, to be used for fulfilling part of the
reporting obligations under Article 13.7 of the Paris Agreement.

Conclusions
CRTs for GHG Inventories │Lorenz Moosmann│CCXG│ 25 November 2020
● Common Reporting Tables (CRTs) are one specific way of providing
inventory information. They are a central element of the transparency
framework under the Paris Agreement and promote transparency and
comparability of inventory data.
● Time available for the development of CRT reporting software is limited;
experience from current electronic reporting should feed into this
development.
● In order to have reporting software available in time for the reporting
deadline under the transparency framework, a timely agreement on the
CRTs is central.
