Notes on data changes

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

• CRT data for 1990-2022 has been included. It replaces and extends NC3 and DI data which only covered some sectors and gases
  • CO2 emissions in 1.A are lower because the post 20202 growth rates in CRT data are lower than those in EI data which was used to extrapolate country reported data in PRIMAP-hist v2.6
  • N2O emissions in M.AG.ELV are available from country reported data for the first time leading to lower emissions in PRIMAP-hist CR.
  • Similarly, country reported data replaced EDGAR for CH4 in 1.B.2 leading to higher emissions.
  • Lower HFC emissions are also due to the newly available country reported data.
  • Higher CO2 from 2.A is also due to the new country reported data.
  • High removals in LULUCF CO2 data come directly from CRT data.
• Changes in the TP time-series come from updated EDGAR and FAO data. FAO has adjusted data for the latest years while EDGAR has updated full time-series with the main change coming from the waste sector.

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.
