Notes on data changes

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

• CRT data from BTR1 covering 2000-2022 has been added. It replaces and extends data from BUR5.
  • Total emissions changes are smaller than individual sector changes because these partly cancel.
  • The new data significantly differs from older submissions for many sectors and gases and over the full time-period.
• Changes in the TP time-series come directly from 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.
