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 Hong Kong, thus CR and TP time-series are identical.

• 1.A, CO2: Emissions in recent years are higher due to the inclusion of CDIAC 2023 data.
• 2.D, CO2: Emissions in 2.D (non-energy products from fuels and solvent use) are much lower in EDGAR 8.0 than in EDGAR 7.0 and thus emissions in PRIMAP-hist v2.5.1 are lower 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
