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.B.2, CH4: Emissions for 2019-2021 are lower in EDGAR 8.0 than in EDGAR 7.0 leading to lower 2022 emissions in PRIMAP-hist v2.5.1
• 3.A, CH4: FAO 2023 emissions are slightly lower for 2020 then FAO 2022 leading to lower 2022 emissions in PRIMAP-hist.
• 1.A, CO2: CDIAC 2023 data are lower for 2017 than CDIAC 2020. This leads to lower 2017 to 2022 emissions in the TP scenario and lower 2018-2020 emissions in the CR scenario.
• M.AG.ELV, CH4:  New FAO data are much lower starting in 2016.

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
