Inventory Report (NIR) submitted in the year 2005 to the United Nations Framework Convention on Climate Change (UNFCCC) It contains national greenhouse gas emission inventories for the period 1990 to 2003, and the descriptions of the methods used to produce the estimates A CD on the back flap of the report contains tabular data in the Common Reporting Format (CRF) covering the United Kingdom’s greenhouse gas emissions for the same period The report is compiled in accordance with the new UNFCCC Inventory Reporting Guidelines agreed by the Conference of Parties at its eighth session (COP8), which took place in New Delhi from 23 October to November 2002 As agreed at COP8 in Decision 18/CP8, 2004 was the first year during which Parties were expected to use these Guidelines, which are set out in document FCCC/CP/2002/8 The UK used these Guidelines for its NIR submitted in the year 2004 and the present report follows the same reporting structure as that used in the 2004 NIR The greenhouse gas inventory (GHGI) is based on the same data sets used by the National Atmospheric Emissions Inventory (NAEI) for reporting atmospheric emissions under other international agreements The GHGI is therefore consistent with that of the NAEI where they overlap This inventory is compiled on behalf of the UK Department for Environment, Food & Rural Affairs (Defra) Global Atmosphere Division, by the National Environmental Technology Centre (NETCEN) We acknowledge the positive support and advice from Defra throughout the work, and we are grateful for the help of all those who have contributed to this NIR A list of the contributors can be found in Chapter 12 The GHGI is compiled according to IPCC Good Practice Guidance (IPCC, 2000) Each year the inventory is updated to include the latest data available Improvements to the methodology are made and are backdated to ensure a consistent time series Methodological changes are made to take account of new data sources, or new guidance from IPCC, relevant work by CORINAIR, new research, or specific research programmes sponsored by Defra UK NIR 2005 (Issue 1) netcen Page iv Units and Conversions Emissions of greenhouse gases presented in this report are given in Gigagrammes (Gg), Million tonnes (Mt) and Teragrammes (Tg) GWP weighted emissions are also provided To convert between the units of emissions, use the conversion

Indirect Indirect Indirect CO NMVOC NOX SO2 Carbon monoxide Non-methane volatile organic compound Nitrogen oxides (reported as nitrogen dioxide) Sulphur dioxide HFCs, PFCs and SF6 are collectively known as the ‘F-gases’ UK NIR 2005 (Issue 1) netcen Page vi Executive Summaries ES.1 The United Kingdom ratified the United Nations Framework Convention on Climate Change (UNFCCC) in December 1993, and the Convention came into force in March 1994 Parties to the Convention are committed to develop, publish and regularly update national emission inventories of greenhouse gases (GHGs) This report is the UK’s National Inventory Report (NIR) submitted in 2005 It contains greenhouse gas emissions estimates for the period 1990 to 2003, and describes the methodology on which the estimates are based The report and the attached Common Reporting Format (CRF) have been compiled in accordance with UNFCCC reporting guidelines on annual inventories contained in document FCCC/CP/2002/8 and Decision 18/CP8 of the Conference of Parties The UK’s greenhouse gas (GHG) inventory is compiled under contract to the UK Department for the Environment, Food and Rural Affairs (Defra) by the National Environmental Technology Centre (NETCEN) of AEA Technology NETCEN also compiles the UK’s National Atmospheric Emissions Inventory, used for reporting emissions to other international agreements Most of the underlying information is held on common databases and this helps ensure consistency between the inventories Emissions from the agricultural sector (Sector 4) are provided by Defra’s Land Management Improvement Division on the basis of a contract with the Institute of Grassland and Environmental Research (IGER), and estimates for Land-use Change and Forestry (LUCF) (Sector 5) are produced on behalf of Defra by the UK Centre for Ecology and Hydrology (CEH) Defra also funds research contracts to provide improved emissions estimates for certain sources such as fluorinated gases, landfill methane, and to provide estimates for previously unreported sub-sectors such as methane from closed coal mines, included for the first time in the UK inventory in this submission The inventory covers the six direct greenhouse gases under the Kyoto Protocol These are:       Carbon dioxide Methane Nitrous oxide Hydrofluorocarbons (HFCs) Perfluorocarbons (PFCs) Sulphur hexafluoride (SF6) These gases contribute directly to climate change owing to their positive radiative forcing effect Also reported are four indirect greenhouse gases:     Nitrogen oxides (reported as NO2) Carbon monoxide Non-Methane Volatile Organic Compounds (NMVOC) Sulphur dioxide The structure of the 2005 National Inventory Report follows that of the 2004 report Chapter provides an introduction and background information on greenhouse gas UK NIR 2005 (Issue 1) netcen Page vii Executive Summaries inventories Chapter provides a summary of the emission trends for aggregated greenhouse gas emissions by source and gas Chapters to discuss each of the main source categories in detail and Chapter 10 presents information on recalculations, improvements and a summary of responses to review processes There are also Annexes to provide key source analysis and other detailed information as set out in the Guidelines The UK’s inventory is used to provide historical data consistent with projections of GHG emissions for the UK’s Climate Change Programme, most recently updated in the Consultation Paper produced for the Review of the UK Climate Change Programme published in December 2004 The programme sets out policies to ensure that the UK delivers its legally binding target under the Kyoto Protocol to reduce emissions of the basket of the six greenhouse gases to 12.5% below 1990 levels over the first commitment period 2008-2012, and to move the UK towards its domestic goal of a 20% reduction in carbon dioxide emissions below 1990 levels by 2010 The Energy White Paper published in 2003 announced the goal of putting the UK on a path to cut CO by 60% by 2050, with real progress by 2020 The programme is currently under formal review and is expected to be revised by summer 2005 UK NIR 2005 (Issue 1) netcen Page viii Executive Summaries ES.2 Tables ES1 and ES2 summarise the emissions of each greenhouse gas expressed in terms of carbon dioxide and carbon
