129. Diversity in the coverage of sectors and gases across the communicated INDCs
poses a key challenge to assessing the aggregate effect of the INDCs in terms of global
GHG emissions, as the aggregate level of emissions resulting from the INDCs in 2025 and
2030 is only a partial estimate of global emissions, excluding emissions from sectors and
gases not covered by the communicated INDCs.
130. Differences in the coverage of gases across the INDCs do not have consequences for
the evaluation of their aggregate effect itself, as long as such coverage is transparently
presented ex ante, but it could affect the estimated total emission reductions and the
calculation of the overall impact on increasing the total level and concentration of GHG
emissions in the atmosphere.
5. Assumptions and methodological approaches, including those used for estimating and
accounting for anthropogenic greenhouse gas emissions and, as appropriate, removals
131. Most Parties communicated some information on the assumptions and
methodological approaches used for estimating and accounting emissions and removals,
with varying level of detail. Most of those assumptions and methodologies relate to the
estimation and projection of GHG emissions and removals. The quality and quantity of the
information varied greatly, depending primarily on the communicated mitigation target and
national capacity. Some Parties also provided information on the source of their data,
including references to national studies, their GHG inventory and national communications.
Reporting guidelines
132. To respond to the requirements to prepare and communicate national inventories of
GHGs, Parties use guidelines prepared by the IPCC, including: the Revised 1996 IPCC
Guidelines for National Greenhouse Gas Inventories; the IPCC Good Practice Guidance
and Uncertainty Management in National Greenhouse Gas Inventories (hereinafter referred
to as the IPCC good practice guidance); the IPCC Good Practice Guidance for Land Use,
Land-Use Change and Forestry (hereinafter referred to as the IPCC good practice guidance
for LULUCF); and the 2006 IPCC Guidelines.
