UK National Atmospheric Emissions Inventory (NAEI) and Greenhouse Gas Emissions Inventory (GHGI) 2008-11 - AQ0711

The UK National Atmospheric Emissions Inventory (NAEI) compiles estimates of pollutant emissions to the atmosphere from UK sources such as cars, trucks, power stations and industrial plant. Forty-four different pollutants are included in the inventory which is published on an annual basis covering the period 1970 to (publication year – 2). The UK Greenhouse Gas Inventory (GHGI) inventory provides an independent estimate of the UK’s GHG emissions for reporting to the United Nations Framework Convention on Climate Change (UNFCCC), and is updated annually. To deliver these estimates, the inventory team at AEA collect and analyse information from a wide range of sources – from national energy statistics through to data collected from individual industrial plants. These emission inventories provide policy makers and the public with an understanding of the key polluting sources, how these sources have developed with economic growth and how they are likely to contribute to pollution in the future. This understanding is essential for a focused response to the problems associated with air pollution and to meet the demands of sustainable development

This project will deliver state-of-the-art air emission inventories - NAEI and GHGI - for statutory international, European and national emissions reporting, for national policy development and for public information.

The UK has an international statutory obligation to report specific air emissions inventory data to a required format and level of transparency. The data has to conform to well defined quality assurance and quality control (QA/QC) requirements and must be reported in a timely manner. Furthermore, data from the inventories are now reported as National Statistics.

This project must also provide air emissions data of sufficient detail and transparency for use in important UK assessment, policy and public information functions performed or supported by Defra including:

• Supporting Local Authorities in their statutory obligation to review the air quality within their areas against the National Air Quality Standards;
• UK air pollution climate mapping;
• Acid deposition mapping;
• Policy evaluation and formulation;
• Expert groups on Air Quality;
• Responding to specific questions from the public;
• Annual national statistical reporting;
• Responding to Parliamentary Questions; and
• Responding to the Climate Change Committee.

This project will ensure that the inventories are continuously developed so that their overall quality is maintained and improved. This project will ensure the provision of accurate information and support a large number of important local, national and international decisions affecting UK and Regional Air Quality and Climate as well as the UK’s economic prosperity.
