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.

• “Other” N2O is much higher because we now use EDGAR instead of FAOSTAT as originally intended (CR, TP). This also leads to changes in the waste sector.
• We have removed 1993 agricultural data from UNFCCC DI data because it is inconsistent with data for other years. This has reduced cumulative agricultural emissions in the CR scenario.
• The high 2022 change in energy CO2 is from updated EI data (CR and 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
