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.

• We have added EEA 2024 inventory data.
• The high reduction in energy CO2 comes from EEA2024 data which does not show the steep 2022 increase in emissions EI2023 shows. (CR)
• For HFCs EEA2024 data replaces the extrapolated value from v2.5.1 leading to lower emissions in 2022 (CR and TP)
• CH4 from waste is lower for all years in EEA2024 than in CRF2023 leading to lower emission in PRIMAP-hist v2.6 (CR)
• N2O from Chemical industry was 0 since 2002 in CRF2023 and PRIMAP-hist v2.5.1. In EEA2024 it is marked as NaN and thus takes from EDGAR 8.0 for PRIMAP-hist v2.6 leading to higher emissions (CR).
• More changes to 2022 emissions due to the updated country reported data (F-gases, CO2 in 1.B.3) (CR, TP)

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
