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.

• Changes in energy, flaring and cement CO2 are due to updated third party data. Changes in TP and CR time series are very similar.
• Changes in sectors 4 and 5 are due to the removal of FAOSTAT data.
• The high change in post-2016 N2O emission from chemical industry (2.B) comes from the shorter extrapolation trend period.

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
