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.

• We have added data from the official 2024 release of the US GHG inventory.
• The USA report non-energy use of fuels under 1.A.5 in CRF. We have mapped the non-energy use of fuels data reported in the 2024 inventory to 2.D (Non-energy products from fuels and solvent use). Thus we have changes for categories 1.A and 2.D which don’t affect the totals, as emissions are moved from 1.A to 2.D (CR scenario).
• F-gas emissions estimates are higher in the 2024 inventory than in CRF2023 data and in consequently higher in PRIMAP-hist v2.6 than in v2.5.1 (CR scenario).
  
• 2022 changes in the TP scenario are due to updated 2022 data (E I2024, and for f-gases the 2024 inventory which is used for 2022 growth rates)

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
