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.

• M.AG.ELV, N2O:  Emissions in FAO 2023 are higher than in FAO 2022.
• 1.B.2, CH4: Emissions in EDGAR 8.0 are much lower than in EDGAR 7.0.
• 1.A, CO2: A change in downscaling of CDIAC data for the former Soviet Union to its member states has lowered pre-1990 emissions. The shares are now calculated based on the shares in the first year with data for the individual states instead of a multi year average. This is more realistic as the rapid emissions decline after 1990 differs by country.

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
