Notes on data changes

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

• CRT data from BTR1, which covers 1990-2022 replaces and extends BUR1 data.
• In the CR time-series we have several high changes.
  • Livestock emissions are down by 50% (CH4) to 90% (N2O) in 2023 and 29-90% for cumulative emissions. The NIR states that “The drop in 2022 is due to revision of national agricultural statistics”
  • Fugitive emissions from oil and gas have been revised downwards for CH4 and upwards for CO2.
  • CO2 emissions from several industrial sectors have been revised.
• In the TP scenario the changes are due to updated EDGAR data with high changes in sectors 1.B.2 and 4.

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.
