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:  Updated CDIAC data show higher emissions than the CDIAC data used in PRIMAP-hist v2.5.  The steep decline in emissions in the EI dataset (2021 and 2022) leads to lower emissions in 2022.
• 1.B.1, CH4: EDGAR 8.0 data are lower than EDGAR 7.0 after year 2000.
• 1.A, CH4: EDGAR 8.0 data are higher than EDGAR 7.0

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
