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.

General note: We have no country reported data for Brunei Darussalam, thus the CR and TP time-series are identical except for LULUCF.

• 1.A, CO2: Updated CDIAC emissions lead to higher emissions after 1990
• 1.B.2, CH4: EDGAR 7.0 showed an emission decline in 2020 which is not present in EDGAR 8.0, thus 2022 and cumulative emissions are higher in v2.5.1 than in v2.5.

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
