Notes on data changes

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

• CRT data from BTR1 has been added allowing the use of country reported data for the first time. Consequently this introduces completely new time-series as the CR time-series was identical to the TP time-series in PRIMAP-hist v2.6.1 and earlier versions.
  • The changes are much higher for recent years as especially recent emissions differ between country reported and third party data especially CO2 in 2.A.
  • Many of the differences that affect the full time-series are for sectors and gases which have high uncertainty, such as agriculture, waste, and CH4 from energy.
• The TP time series has only changed for energy CO2 because of the new EI data and waste CO2 which has been added from country reported 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.
