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.A, CO2: New CDIAC data differ from older data for most years including pre-1990. Emissions for the latest years and 2022 are lower because data for 2017 is lower in CDIAC 2023 than in CDIAC 2020.
• 3.A, CH4: 2022 data are lower due to updated FAO and EDGAR data. Data for several other recent years are also lower.
• M.AG.ELV, N2O: 2022 data are lower due to updated FAO and EDGAR data. Data for several other recent years are also lower.

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
