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: There are no country reported data for Saint Helena, Ascensions and Tristan da Cunha. Thus the CR and TP time-series are identical.

• 1.A, KYOTOGHG (AR6GWP100): The changes are due to higher CDIAC emissions for the last years which were not modeled by the EI data based extrapolation used in v2.5. Changes in cumulative emissions are due to the changes in the latest years. Additionally pre 1980 emissions have changed as many data points have beel replaced by 0 in CDIAC data.
• 1.B.1, KYOTOGHG (AR6GWP100): Higher emissions both in 2022 and cumulatively are due to higher emissions in eDGAR v8.0. compared to v7.0 used in PRIMAP-hist v2.5.
• 2, KYOTOGHG (AR6GWP100): EDGAR 8.0 includes CO2 emissions in 2.D for the first time which explains the high changes. Before emissions in category 2 were near zero.

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
