Notes on data changes

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

• CRT data has been included but replaces official data which shows only small differences which might come from different regional definitions underlying the reporting.
  • The small change in energy CO2 comes from a slight change in country reported energy CO2 emissions for 2022.
  • Further changes for 2023 emissions in the CR scenario are form updated EDGAR data.
  • N2O emissions in sector 5 (other) are now non-zero, because they are reported as missing in CRT and thus takes from EDGAR.
• 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 changes coming from the fugitive CH4, waste CH4, other N2O, and HFCs
• Pre-1990 changes come from changed pre-1990 EDGAR emissions (e.g. N2O in 2.B) (EDGAR)

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.
