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 has higher emissions for 2015-2017 leading to higher emissions in PRIMAP-hist especially in the TP time-series. The CR and TP time-series are very similar in PRIMAP-hist v2.5.1 as CDIAC and country reported data are very similar.
• 1.B.2, CH4: Extrapolated data for 2022 has been replaced by EDGAR 8.0
• 1.B.1, CH4:  Extrapolated data for 2022 has been replaced by EDGAR 8.0.
• M.AG.ELV, N2O: New FAO data are lower for 2020 leading too lower emissions for the latest years in PRIMAP-hist.
• M.AG.ELV, CH4: New FAO and EDGAR data change 2021 and 2022 emissions.
• M.AG.ELV, CO2: EDGAR 8.0 emissions are lower than EDGAR 7.0 starting 2013 leading to much lower post 2013 emissions in PRIMAP-hist. This also affects (to a lesser extent) the CR time-series as the last year with country reported data is 2013.

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
