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.

• We have included EEA 2024 data for Portugal. 2022 changes are mostly due to this new data replacing data / growth rates from third party sources.
• Sector 1.B.2 (oil and gas) has very high relative change. PRIMAP-hist v2.5.1 showed a steep decline for 2022 while we have increasing emissions in EEA data. The very low 2022 data point in v2.5.1 likely comes from a scaling problem due to the almost zero EDGAR 8.0 data.
• Waste N2O emissions in the CR scenario are over 140% higher cumulatively and over 270% higher in 2022. This increase is due to an increase in estimates for emissions from domestic wastewater treatment and discharge.
• Cumulative CH4 emissions from waste are roughly 10% lower than in v2.5.1 due to lower country reported emissions. HFCs emissions are lower in the CR scenario after 2000 because emissions from refrigeration and air conditioning are lower in EEA 2024 than in CRF 2023.
• 2022 changes in the TP scenario are due to updated input data and affect more sectors than energy and cement CO2 as country reported data are used for f-gas 2022 growth rates and some sectors which are not covered by EDGAR data for Portugal.
• Changes in sectors 4 and 5 in the TP scenario are due to the removal of FAOSTAT 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. ## country reported scenario
