Notes on data changes

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

• CRT data covering 2010-2022 has been added. It is the first country reported data source with sufficient coverage. Thus the CR scenario differs from the old version in most sectors and gases.
• The TP scenario has high changes for several sectors as well because of changes in EDGAR data most importantly for fugitive CH4 from oil and gas (1.B.2).
• The TP time series is also impacted by the CRT data e.g. for CO2 in 2.B because no third party data exists for this sector and gas.

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.
