Notes on data changes

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

• No new country reported data has been included
• The high relative change in SF6 emissions comes from EDGAR data which shows increasing emissions and replaces numerical extrapolation which continued the downward trend in emissions. For HFCs the situation is similar, but with decreasing EDGAR emissions replacing a slightly increasing trend.
• For 1.B.2, CH4 there is no country reported data and EDGAR emissions have increased by four orders of magnitude thus the relative change is very high.
• 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.
