<0>Notes on the methodological differences and differences in categorisation between local authority estimates and UK estimates in table 4.1 <0>This sheet contains information about the statistics presented in Methodological differences and differences in categorisation between local authority estimates and National End User Emissions Inventory table in table 4.1 in this document. <0>The fuel specific totals for the Industrial sector show a large difference for solid fuels and non-fuel emissions. This is because of a difference in definition of blast furnace gas between these two datasets. This gas is aggregated into the solid fuel column for the national total end user dataset because it is derived from coke. However for the local authority dataset it has been classified as a process gas and hence aggregated into the non-fuel column. The total end user emission from blast furnace gas is 9,027 kt CO2e in 2023. <0>For gas and electricity there is a difference in the method for splitting between domestic and non-domestic consumption, and in splitting non-domestic between agriculture, industrial, commercial and public sector. The local authority dataset uses the domestic/non-domestic splits presented in the DESNZ sub-national fuel consumption datasets, and additional splits for non-domestic derived from the local authority greenhouse gas IDBR employment based mapping methdology, while the national inventory uses the split presented in DUKES. More detail on this can be found in the Technical Report. <0>The other differences in the domestic line are due to differences in classification of fuels between these two datasets: petroleum coke (213 kt CO2e) is classed as oil in the national end user dataset and peat (5 kt CO2e) is classed as non fuel. Both of these fuels are classed as solid fuel in this local authority dataset. <0>The 52 kt CO2e difference in the transport line is due to a difference in classification of engine lubricant emissions. This is classified as non fuel in the National end user reporting and as an oil based emissions for the local authority dataset. A 197 kt CO2e difference in emissions from gas also arises due to LNG use in road transport, classified as liquid fuel in this local authority dataset and gas in National end user reporting. <0>The remaining differences in the industrial, commercial and public sector amount to 4,186 kt CO2e in 2023 across solid fuel, oil and non-fuel emission. These differences are the only actual differences in total emissions between these two datasets as opposed to differences in aggregation and exclusions. They are due to the differences between the estimates of emissions at large point sources and those in the national totals. An explanation for these differences is provided in Section 4 of the Technical Report.
