Notes on data changes

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

• CRT data from BTR1 has been added which covers 2019, 2020, and 2021 and extends the data from NC4 and UNFCCCDI. As the last data year of the NC and DI data was 2016 the new data changes emissions estimates for recent years for many sectors and gases.
  • The by far most important change for 2020 to 2023 is an increase in energy CO2 emission of over 20%. The reason is that CDIAC data used for 2017-2020 in v2.6.1 showed a steep emission decline from 2019 to 2020 which is not present in the country reported data. For cumulative emission the impact is much smaller.
  • Further sectors with high relative changes for recent years are: M.AG.ELV, (N2O, CH4), 3.A (CH4, N2O), IPPU (CH4, CO2), 1.B.2 (CH4)
• Changes in the TP scenario are very small, limited to 2023, and come from the updated EI data for energy CO2.

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.
