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.

• 1.A, CO2: CDIAC 2023 data show a decline in emissions for 2019 and 2020. This decline is not present in the EI data used for these years in PRIMAP-hist v2.5. Thus 2022 emissions ar elower in PRIMAP-hist v2.5.1.
• 1.B.2, CH4: EDGAR 7.0 emissions showed a steep increase for 2021 while EDGAR 8.0 only shows a slight increase. This leads to lower 2022 emission in PRIMAP-hist.

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
