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 covers only 2000-2017 thus the third party data has a high influence on the CR time-series. Changes in the CR time-series come from updated third party data (EDGAR, FAO) which is used to extrapolate the country reported data.
  • Emissions in some sectors (e.g. waste, M.AG.ELV, CH4, 5) have no country reported data and changes come directly from EDGAR and FAO data.
  • In M.AG.ELV, N2O we have changes before 1990 which come from updated FAO data.
• In the TP time-series changes in M.AG.ELV are higher as the are scaled to the lower country reported data in the CR scenario.

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.
