Notes on data changes

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

• CRT data has been included which replaces official data.
• The CRT data is consistently higher for energy CO2 and consistently lower for CO2 in 2.D. This is due to different accounting of non-fuel use of fossil fuels which is reported under 1.A.5.a in CRT data instead of 2.D.
• The lower HFC emissions are likely also due to an accounting difference as the CRT data is in line with CRF2023.
  • Other 2023 changes in the CR time-series are mostly due to updated EDGAR data which is used to extrapolate country reported emissions.
  • For N2O in sector 5 there are no country reported emissions and the changes in EDGAR emissions are directly reproduced in the CR time-series.
• In the TP time-series the main changes are due to updated EDGAR 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.
