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:  EI 2023 data shows a deep emissions drop in 2020 and 2021 which is not as pronounced in CDIAC 2023 leading to higher emissions in 2020-2022 which also affect cumulative emissions.
• 2, N2O:  EDGAR 7.0 data has very high emissions in 2.B (chemical industry) for 2019-2021 which are not present in EDGAR 8.0 leading to much lower emissions in PRIMAP-hist v2.5.1 for 2019-2022.

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
