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.

• 2024 EEA data has been added.
• HFCs data is much lower in EEA2024 than in CRF2023 after 2010 leading to much lower 2022 f-gas emissions and lower cumulative emissions in the CR scenario. The origin of the changes is mainly sector 1.F.1 (Refrigeration and air conditioning).
• The lower cement CO2 emissions in 2022 are due to a decline in EEA2024 while Andrew cement data shows constant emissions.
• Lower N2O in M.AG.ELV in 2022 comes from a decline in emissions that is not as strong in FAOstat data use in v2.5.1. The TP scenario shows changes for 2022 for several sectors and gases which are due to changes in input data (EI2024 for 1.A, 1.B.2, CO2) and replacement of numerical trends with actual data (f-gases, CH4 in 1.B.3). cumulative emissions in the third party priority scenario only show very small changes.
• Changes in sectors 4 and 5 in the TP scenario are due to the removal of FAOSTAT data.

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
