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.

• Overall 2022 emissions in the CR scenario are 3.9% lower than in PRIMAP-hist v2.5.1. Cumulative emissions are 1.2% higher (CR scenario). The main reason is the inclusion of BUR3 and NC4 which adds country reported data for 2017 and 2018.
• Some inconsistencies in the downscaling od UNFCCCDI data were fixed.
• The main contributions come from energy CO2, CO2 from mineral and chemical industry, and fugitive CH4 from solid fuels for both 2022 and cumulative emissions.
• Total agricultural emissions have only slight changes, because higher CH4 from livestock mostly cancel with lower N2O from agricultural emissions excluding livestock.
• Changes in the TP scenario are small and mainly in sectors 4 and 5 due to the removal of FAOSTAT data.

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
