Notes on data changes

Here we list notes explaining important emissions changes for the country.

• CRT data has been included but replaces official data reported to the EU which does not show noteworthy differences. The main changes in 2023 are due to EDGAR growth rates replacing numerical trend calculations.
• Changes in the TP time-series have the same origin.

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.
