presentación oral invitada en el workshop REMEDIA 2012 en la temática de mitigación de GEi transversal

1. Reporting GHGs emissions by sources
and removals by sinks under the
UNFCCC: GHG inventories
M. J. S
REMEDIA Workshop, 8-9 March 2012, Bilbao

2. The global estimates integrate or
average regional, national and
subnational estimates of
GHGs….
The global portafolios of measures need to be
scale down to regions, countries and sub-national
levels….

6. Details inventory cycle – UNFCCC
In 1999 the COP decided that:
•All Annex I Parties‘Common Reporting Format’
annually, using the
were required to report an inventory
•The reviews were also strengthened and had to team of
be
conducted under the collective responsibility of a
experts nominated by Parties and coordinated by the
UNFCCC secretariat.
For the two-year trial period (2000–01) the new review procedures were
voluntary but from 2003 they became mandatory.
Annex I must use ‘Revised 1996 IPCC guidelines’ and are also
encouraged to apply IPCC’s ‘Good practice guidance and uncertainty
management in national GHG inventories’

7. Details inventory cycle – UNFCCC
Non-Annex I Parties should use the ‘Revised 1996 IPCC
guidelines’ and are also encouraged to apply IPCC’s
‘Good practice guidance and uncertainty management in
national GHG inventories’ – and should include an
analysis of key sources along with estimates of
uncertainties.
Countries should provide estimates on a gas-by-gas
basis for carbon dioxide, methane and nitrous
oxide, though they are also encouraged to provide
information on fluorinated gases as well as on precursor
gases such as carbon monoxide, non-methane volatile
compounds, and other oxides of nitrogen. They can also
include other gases not controlled by the Montreal
Protocol, such as oxides of sulphur.

9. IPCC Guidelines and Guidance
Inventory agencies, when preparing the national greenhouse gas inventory for the LULUCF Sector for annual
reporting under the UNFCCC, should follow steps:
1. Use the approaches in Chapter 2 (Basis for Consistent Representation of Land Areas), singly or in
combination, to estimate land areas for each land-use category relevant to the country. For each land-use
category, inventory agencies should complement the advice in Chapter 2 with the more detailed guidance in
Chapters 3 and 4 on the preparation of specific emission and removal estimates and, if relevant, the
reporting on the activities under the Kyoto Protocol.
2. Follow the good practice guidance in Chapter 3 (LUCF Sector Good Practice Guidance) to estimate the
emissions and removals of greenhouse gases for each land use, land-use change and pool relevant to the
country. The decision trees in this chapter guide choices of method in terms of tiers. The tier structure used
in the IPCC Guidelines (Tier 1, Tier 2 and Tier 3) is hierarchical, with higher tiers implying increased accuracy
of the method and/or emissions factor and other parameters used in the estimation of the emissions and
removals. Key categories should be identified following the guidance in Chapter 5 and the results taken into
account in the application of the decision trees.
3. If necessary, in some cases, collect additional data (if required to implement a particular tier) to improve
emission factors, other parameters and activity data.
4. Estimate uncertainties at the 95% confidence level, using sectoral advice and the detailed guidance in
Chapter 5.
5. Report the emissions and removals in the reporting tables provided in Chapter 3 Annex 3A.2 taking into
account any modifications by SBSTA15 and any additional information as specified under each category.
6. Implement QA/QC procedures as described in the generic guidance in Chapter 5 and specific advice
under each category, including documentation and archiving of the information used to produce the national
emission and removal estimates.

10. IPCC Guidelines and Guidance
Inventory agencies, when preparing the supplementary information for annual reporting of carbon stock
changes and emissions and removals of greenhouse gas emissions resulting from the activities under Article
3.3 and Article 3.4 of the Kyoto Protocol, should additionally:
7. Assess the extent to which the data assembled for the existing national inventory (following steps 1 to 6
above) can meet the supplementary data requirements set out in the supplementary guidance provided in
Chapter 4 of this report, taking into account national choices on definitions and activities elected under Article
3.4, and the requirements in geographical location.
8. Following this assessment collect or collate any additional information necessary to meet the supplementary
data requirements, using the advice in Chapter 4 and the references it contains to other Chapters.
9. Follow the advice in Chapter 4 on reporting and documentation when providing the supplementary
information in the national inventory report.

16. Inventories are tools……
• To track emissions by sources and
removals by sinks.
• To track progress on the
implementation of policies and
measures to mitigate climate change
(mitigation portafolios).
• That can be used at different scales.

17. Inventories need to be….
• Consistent in their time series.
• Transparent in their estimates.
• Comparable.
• Complete.
• Accurate, not overestimate or
underestimate.
• Spatially consistent at different scales.
• If used for compliance purposes,
conservative in their estimates.
• And constructed in a cost effective way.

18. Inventory linkages with overall
production cycles….
• Inventories are compiled and reported by
categories within sectors.
• Policies and measures aim to reduce
emissions and enhance sinks.
• Ground actors, producers and consumers,
require information about the associated net
emissions related to their activities (overall
cycle emissions and food prints).
• Linking inventories with such information it
will be necessary in the future.
