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 added the 2024 release of the official greenhouse gas inventory for the UK.
• The 2022 change in energy CO2 is due to a decrease in emissions in the official inventory while EI2023 shows increasing emissions for 2023.
• HFC emissions are lower in 2022 and in cumulative emissions because EEA2024 data is lower than CRF2023.
• In the CR scenario there are further smaller changes from the new country reported data.
• In the TP scenario the energy CO2 change for 2022 is from a slight reduction in emissions from EI2023 to EI2024.
• 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
