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.

• The 2024 inventory report has been included.
• The change in CH4 from 1.B.2 comes from strongly increased emissions factor for venting of CH4 in oil and gas production.
• Fugitive CO2 emissions from solid fuel production are included as 0 in the new inventory and are now 0 in the CR time-series.
• Higher CH4 emissions from fossil fuel combustion (1.A) are mostly due to higher CH4 emissions factors for gaseous fuels.
• Changes in HFCs come from replacing numerical trends with data from the 2024 inventory.
• In the TP scenario the main reason for 2022 changes are the f-gas trends.

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
