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.

• No new country reported data was included for Singapore.
• Overall changes are below 1% and due to updated EI energy CO2 data.
• Because the latest year with country reported data is 2018 and some subsectors and gases in IPPU are not covered by EDGAR data the change in trend period for numerical extrapolation influences several sectors and gases for post 2018 in the CR scenario.

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
