Explanation for the various totals of UK greenhouse gas emissions reported to different authorities
There are various totals of UK greenhouse gas emissions reported to different authorities depending on the reporting requirements.
The main reason for this comes from different geographical coverages used when estimating the UK greenhouse gas emissions. Overseas Territories and Crown Dependencies that are associated with the UK are sometimes included or excluded from the emissions totals. The main geographical coverages used are:
UK National Statistics - The geographical coverage of these statistics is based on the UK and the Crown Dependencies of Jersey, Guernsey and the Isle of Man.
Kyoto Protocol commitment - The UK’s progress against the Kyoto Protocol commitment is based on a geographical coverage of the UK, the Crown Dependencies of Jersey, Guernsey and the Isle of Man and the Overseas Territories that have ratified the Kyoto Protocol (Cayman Islands, Falkland Islands, Bermuda, Montserrat and Gibraltar).
Commitment under the EU Monitoring Mechanism - Coverage only includes parts of the UK which are also parts of the EU: the UK and Gibraltar. All Crown Dependencies and Overseas Territories are excluded.
Domestic carbon budgets set under the UK Climate Change Act are based on the UK only, excluding all emissions from the UK’s Crown Dependencies and Overseas Territories.
Differences in the reported totals can also arise from different definitions of emissions from the Land Use, Land Use Change and Forestry (LULUCF) sector. Under the UNFCCC, all emissions and removals from this sector are included, whereas the Kyoto Protocol uses narrower definition of emissions from this source.
It is important to understand the differences between reported emission to ensure that the correct data are used for specific purposes of reporting or analysis.
This publication explains differences between coverages of reported UK emissions in both the National Statistics publications and the UK’s other international and national reporting requirements for greenhouse gases.
