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 1994-2007, thus the third party data has a high influence on the CR time-series.
• The most important changes come from FAO data which has changes post 2017.
• The EDGAR update also contributes with waste, IPPU and fugitive emissions changes.
• For the TP time-series the changes are in the same sectors but waste CH4 plays a larger role.

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.
