Roles and Responsibilities
 
 
Summary
 
The UK Greenhouse Gas Inventory is compiled and maintained by AEA under contract to the Climate Energy, Science & Analysis (CESA) in the UK Department of Energy and Climate Change.
 
AEA is directly responsible for producing the emissions estimates for CRF categories: Energy (CRF sector 1), Industrial Processes (CRF sector 2), Solvent and Other Product Use (CRF sector 3), and Waste (CRF Sector 6). AEA is also responsible for inventory planning, data collection, QA/QC and inventory management and archiving.
 
Agricultural sector emissions (CRF sector 4) are produced by the Defra’s Land Management Improvement Division by means of a contract with North Wyke Research.
 
Land-Use, Land-Use Change and Forestry emissions (CRF sector 5) are calculated by the UK Centre for Ecology and Hydrology (CEH), under separate contract to CESA.
 
National Inventory System Requirements
 
The Marrakesh Accords of the Kyoto Protocol (Decision 20/CP7) define the requirements for National Inventory Systems (NIS), including the need to establish legal, procedural and organisational arrangements to ensure that all parties to the Protocol estimate and report their GHG emissions in accordance with relevant decisions of the COP, facilitate UNFCCC Reviews and improve the quality of their inventories. Under related EU legislation set out in Decision 280/2004/EC the UK was required to have in place it's NIS by 31st December 2005.
 
The development of more formal agreements between DECC and Key Data Providers (KDPs) is ongoing and will specify the framework of data supply e.g. data quality, format, timeliness and security to underpin the GHG inventory.
 
The figure below shows the main elements in the UK National Inventory System. DECC is the Single National Entity responsible for submitting the UK's greenhouse gas inventory (GHGI) to the UNFCCC. AEA compiles the GHGI on behalf of DECC, and produces disaggregated estimates for the Devolved Administrations within the UK.
 
Key Data Providers include other Government Departments such as Department for Business, Enterprise & Regulatory Reform (BERR) and Department for Transport (DfT), Non-Departmental Public Bodies such as the Environment Agency for England and Wales (EA) and the Scottish Environmental Protection Agency (SEPA), private companies such as Corus, and business organisations such as UK Petroleum Industry Association (UKPIA) and UK Offshore Oil Association (UKOOA).
 
Responsibilities and Data Flows Schematic
 
The organisational Structure of the UK NIS can be summarised as follows:
 
Key Organisations Schematic
 
The following sections summarise the roles and responsibilities of key stakeholders in the UK NIS, using the terminologies defined within the Marrakesh Accords for each stakeholder group.
 
Single National Entity: DECC
 
As the designated Single National Entity for the UK GHG NIS, DECC has the following roles and responsibilities:
 
NIS Management & Planning
Bullet Overall control of the NIS development & function;
Bullet Management of contracts & delivery of GHG inventory;
Bullet Definition of performance criteria for NIS key organisations.
 
Development of Legal & Contractual Infrastructure
Bullet Review of legal & organisational structure;
Bullet Implementation of legal instruments and contractual developments as required to meet guidelines.
 
Inventory Agency: AEA
 
As the designated Inventory Agency for the UK GHG NIS, AEA has the following roles and responsibilities:
 
Planning
Bullet Co-ordination with DECC to deliver the NIS;
Bullet Review of current NIS performance and assessment of required development action;
Bullet Scheduling of tasks and responsibilities to deliver GHG inventory and NIS.
 
Preparation
Bullet Drafting of agreements with key data providers;
Bullet Review of source data & identification of developments required to improve GHG inventory data quality.
 
Management
Bullet Documentation & archiving;
Bullet Dissemination of information regarding NIS to Key Data Providers;
Bullet Management of inventory QA/QC plans, programmes and activities.
 
Inventory Compilation
Bullet Data acquisition, processing and reporting;
Bullet Delivery of NIR (including associated CRF tables) to time and quality.
 
Key Data Providers
 
Within the UK GHG NIS, organisations that are Key Data Providers have the following roles and responsibilities:
 
Data Quality, Format, Timeliness, Security
Bullet Delivery of source data in appropriate format and in time for inventory compilation, allowing for all required QA/QC procedures;
Bullet Assessment of their data acquisition, processing & reporting systems, taking regard for QA/QC requirements;
Bullet Identification of any required organisational or legal development and resources to meet more stringent NIS data requirements, notably the security of data provision in the future;
Bullet Communication with DECC, AEA and their peers / members to help to disseminate information regarding NIS.
 
Summary of Key Data Sources
 
The GHGI is compiled using the same database as the UK National Atmospheric Emissions Inventory (NAEI). The NAEI is used for reporting under other international agreements and includes emission estimates for greenhouse gases, regional pollutants leading to acid deposition and photochemical pollution, persistent organic pollutants and other toxic pollutants such as heavy metals. The NAEI is available at http://www.naei.org.uk.
 

Energy statistics required for compilation of the NAEI and the GHGI are obtained from the Digest of UK Energy Statistics (DUKES). DUKES is compiled and published by the Department for Business, Enterprise & Regulatory Reform (BERR). DUKES is available here.

 
Information on industrial processes is provided either directly to AEA by the individual plant operators or from:
 
Bullet the Environment Agency's Pollution Inventory (PI) for England & Wales;
Bullet the Scottish Environmental Protection Agency’s European Pollution Emissions Register (SEPA EPER for Scotland);
Bullet the Northern Ireland Department of Environment Inventory of Statutory Releases (ISR for Northern Ireland).
 
Reporting to these UK inventories for the purposes of environmental regulation is a statutory requirement for industries covered by IPPC. The data from these inventory sources is also used to quality check data provided voluntarily by companies directly to AEA.
 
North Wyke Research compiles the inventory for agricultural emissions using agricultural statistics from DECC.
 
The Centre for Ecology and Hydrology (CEH) compiles estimates of emissions and removals from LULUCF using land-use data and information on forestry from the Forestry Commission (a non-departmental public body), DECC, and from other sources.
 
DECC and Defra also fund research contracts to provide emissions estimates for certain sources. A recent Defra-funded study has provided estimates for methane emissions from closed coal mines (Kershaw, 2005). These emissions have subsequently been included in the GHG inventory for the first time, reported within IPCC sector 1B1 – Solid Fuels.
 
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/DECC.
