Notes on data changes

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

• No new country reported data has been included. Changes in the CR time-series are relatively small and come from updated third party data (EDGAR, FAO) which is used to extrapolate the country reported data.
• Changes in the TP time-series come from updated EDGAR data where full time-series have been updated. The main changes come from the waste sector and the energy sector (non-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.
