Notes on data changes

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

• No new country reported data has been included. country reported data does not cover all sectors and gases, thus for some sectors third party data is used directly.
  • The main change for the CR scenario is CH4 in 1.B.1 and comes directly from EDGAR because we have no country reported data.
  • Other CR scenario changes are small and come from EDGAR and FAO data either used to extrapolate country reported data or filling in for missing country reported data.
• In the TP scenario the changes are for similar sectors with the addition of a high reduction of waste CH4 emissions from EDGAR data.

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.
