Notes on data changes

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

• There is no usable country reported data for Cameroon, thus the CR and TP time-series are identical.
• The main change is for waste CH4 and due to updated EDGAR data.
• Additional larger contributions come from fugitive CH4 and CO2 (from EDGAR) and CH4 in M.AG.ELV (from FAOSTAT)

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.
