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: The new CDIAC data shows relatively constant emissions for 2016-2019 while the EI data shows a decline in emissions. This leads to higher emissions in PRIMAP-hist as CDIAC replaces EI for 2018-2020. In the CR scenario the effect is smaller as country reported data are available until 2018.
• 1.B.2, CH4: The 2019-2021 emissions decline is smaller in EDGAR 8.0 than in EDGAR 7.0 leading to higher emissions for the last years.
• 2, CO2:  EDGAR 8.0 data replaces numerical extrapolation for 2022 leading to higher emissions.

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
