Reporting GHGs emissions by sources and removals by sinks under the UNFCCC: GHG inventories M. J. SREMEDIA Workshop, 8-9 March 2012, Bilbao
The global estimates integrate oraverage regional, national andsubnational estimates ofGHGs….The global portafolios of measures need to bescale down to regions, countries and sub-nationallevels….

Details inventory cycle – UNFCCCIn 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 beconducted under the collective responsibility of aexperts nominated by Parties and coordinated by theUNFCCC secretariat.For the two-year trial period (2000–01) the new review procedures werevoluntary but from 2003 they became mandatory.Annex I must use ‘Revised 1996 IPCC guidelines’ and are alsoencouraged to apply IPCC’s ‘Good practice guidance and uncertaintymanagement in national GHG inventories’
Details inventory cycle – UNFCCCNon-Annex I Parties should use the ‘Revised 1996 IPCCguidelines’ and are also encouraged to apply IPCC’s‘Good practice guidance and uncertainty management innational GHG inventories’ – and should include ananalysis of key sources along with estimates ofuncertainties.Countries should provide estimates on a gas-by-gasbasis for carbon dioxide, methane and nitrousoxide, though they are also encouraged to provideinformation on fluorinated gases as well as on precursorgases such as carbon monoxide, non-methane volatilecompounds, and other oxides of nitrogen. They can alsoinclude other gases not controlled by the MontrealProtocol, such as oxides of sulphur.

IPCC Guidelines and GuidanceInventory agencies, when preparing the national greenhouse gas inventory for the LULUCF Sector for annualreporting under the UNFCCC, should follow steps:1. Use the approaches in Chapter 2 (Basis for Consistent Representation of Land Areas), singly or incombination, to estimate land areas for each land-use category relevant to the country. For each land-usecategory, inventory agencies should complement the advice in Chapter 2 with the more detailed guidance inChapters 3 and 4 on the preparation of specific emission and removal estimates and, if relevant, thereporting on the activities under the Kyoto Protocol.2. Follow the good practice guidance in Chapter 3 (LUCF Sector Good Practice Guidance) to estimate theemissions and removals of greenhouse gases for each land use, land-use change and pool relevant to thecountry. The decision trees in this chapter guide choices of method in terms of tiers. The tier structure usedin the IPCC Guidelines (Tier 1, Tier 2 and Tier 3) is hierarchical, with higher tiers implying increased accuracyof the method and/or emissions factor and other parameters used in the estimation of the emissions andremovals. Key categories should be identified following the guidance in Chapter 5 and the results taken intoaccount in the application of the decision trees.3. If necessary, in some cases, collect additional data (if required to implement a particular tier) to improveemission factors, other parameters and activity data.4. Estimate uncertainties at the 95% confidence level, using sectoral advice and the detailed guidance inChapter 5.5. Report the emissions and removals in the reporting tables provided in Chapter 3 Annex 3A.2 taking intoaccount 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 adviceunder each category, including documentation and archiving of the information used to produce the nationalemission and removal estimates.
IPCC Guidelines and GuidanceInventory agencies, when preparing the supplementary information for annual reporting of carbon stockchanges and emissions and removals of greenhouse gas emissions resulting from the activities under Article3.3 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 6above) can meet the supplementary data requirements set out in the supplementary guidance provided inChapter 4 of this report, taking into account national choices on definitions and activities elected under Article3.4, and the requirements in geographical location.8. Following this assessment collect or collate any additional information necessary to meet the supplementarydata 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 supplementaryinformation in the national inventory report.

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.
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.
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.
