Notes on data changes

Here we list notes explaining important emissions changes for the country. ’' means that the following text only applies to the TP time series, while  means that it only applies to the CR scenario. Otherwise the note applies to both scenarios.

• 1.A, CO2: /CR/ The new CDIAC data differs from the data used in v2.5 especially in the period before 2010. This impacts harmonization to country reported data which are only available until 2008 leading to higher post 2008 emissions in v2.5.1. /TP/ While the new CDIAC data continues the old CDIAC 2020 data with constant emissions until 2020 the additional years change the point of harmonization of EI data and thus 2022 emissions. cumulative emissions change mostly due to changes in CDIAC emissions for earlier years.
• 2, CO2: Emissions in 2.D (non-energy products from fuels and solvent use) are much lower in EDGAR 8.0 than in EDGAR 7.0 and thus emissions in PRIMAP-hist v2.5.1 are lower than in v2.5. As there are no country reported data for 2.D, CO2 the CR time-series are affected as well.

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. ## country reported scenario
