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.B.2, CO2 is much higher in 2022 because of a scaling problem in v2.5.1 (EDGAR 8.0 data is almost zero). this also affects cumulative emissions. (CR)
• Cement CO2 is higher in 2022 due to a rise in emissions not modeled by the Andrew cement data used in v2.5.1 (CR)
• Small changes to N2O from agriculture without livestock due to changes from CRF2023 to EEA2024 (CR)

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
