Notes on data changes

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

• CRT data from BTR1 covering 1990-2022 has been included. It replaces and extends data from BUR4. The new data leads to changes for several sectors and gases.
• The main 2023 chnages in the TP time-series, CH4 and N2O in M.AG.ELV are both due to a decline in emissions for 2022 in the new FAO data. Further changes come from the new EDGAR data and the new FAO data. Cumulative emissions changes have the same origin.

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.
