Notes on data changes

Here we list notes explaining important emissions changes for the country. ’' means that the following text only applies to the TP time series, while  means that it only applies to the CR scenario. Otherwise the note applies to both scenarios.

General note: We have no country reported data for Comoros, thus the CR and TP time-series are identical except for LULUCF.

• 1.A, CO2: emission in CDIAC 2023 data are higher than in earlier versions. As Comoros is not included in the EI dataset EDGAR 7.0 data was used to extend CDIAC 2020 in PRIMAP-hist v2.5. EDGAR 7.0 shows a decline in emissions in 2020 which CDIAC 2023 does not show. Thus the increase in 2022 emissions is high. Data for 2021 and 2022 are estimated using numerical extrapolation.
• 1.A, CH4: Emissions are consistently higher as EDGAR 8.0 emissions are consistently higher than EDGAR 7.0
• M.AG.ELV, CH4: 2022 emissions are lower because new FAO and EDGAR data show a continuation of the recent emissions plateau while the numerical extrapolation still factored in the steep emissions rise between 2007 and 2015.

Changes by sector and gas

For each scenario and time frame the changes are displayed for all individual sectors and all individual gases. In the sector plot we use aggregate Kyoto GHGs in AR6GWP100. In the gas plot we usenational total emissions without LULUCF. ## country reported scenario
