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 1994, 2000, and 2006 thus the third party data has a high influence on the CR time-series. Many sectors are not covered by country reported data and third party data is used directly. Changes in the CR time-series are small in terms of total emissions and come from updated third party data (EDGAR, FAO).
• In the TP scenario the changes are for similar sectors with the addition of an increase in waste CH4 emissions from EDGAR data.
• pre-1990 emissions are lower because the EDGAR waste CH4 time-series have changed pre-1990 and pre-1980 emissions are now lower while post-1980 emissions are lower than in the last EDGAR version.

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.
