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.

• The 2024 EEA inventory data has been included.
• The change in 2022 energy CO2 data comes from an emissions decline in the 2024 EEA data where EI2023 showed an emission increase.
• N2O from agriculture without livestock is lower in the EEA2024 data than in CRF2023.
• F-gas emissions remained flat in 2022 in contrast to the declining trend of the previous years.
• Cumulative emission in the CR scenario are almost unchanged.
• The lower emissions in M.AG.ELV, N2O are from generally lower emissions estimates in EEA2024.
• We have fixed an extrapolation issue for CO2 from chemical industry (2.B).
• Emissions in the TP scenario have changed only slightly and mainly for f-gases in 2022 with the same reasons as for the CR scenario.
• 2022 emissions and growth rates for cement CO2 are lower for both scenarios as 2022 emissions in the EEA data and the new Andrew cement data are lower than in the Andrew cement data used in v2.5.1
• Changes in sectors 4 and 5 in the TP scenario are due to the removal of FAOSTAT data.

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
