Details

This publication provides estimates of UK emissions of particulate matter (PM10 and PM2.5), nitrogen oxides, ammonia, non-methane volatile organic compounds and sulphur dioxide.

These statistics are used to monitor progress against the UK’s emissions reduction targets for air pollutants. Emissions reductions in the UK contribute to improvements in air quality alongside a number of other factors. For more information on air quality data and information please refer to the air quality and emissions statistics GOV.UK page.

The National Atmospheric Emissions Inventory website contains information on anthropogenic UK emissions and compilation methods for a wide range of air pollutants; as well as hosting a number of reports including the Devolved Administrations’ Air Quality Pollutant Inventories.

The methodology to estimate emissions is continuously reviewed and developed to take account of new data sources, emission factors and modelling methods. This means the whole emissions time series from 1990 to the reporting year is revised annually.

Please note: Due to methodological updates and improvements which are routinely carried out each year, the data and trends discussed here are not directly comparable to those published in previous iterations of this Accredited Official Statistics release. More information can be found in the accompanying Methods Document. For year-on-year changes in emissions, the trends presented within this document and the accompanying statistical tables should be used.

If you do wish to see the impact of these methodological changes, you can access previous editions of this publication via The National Archives or the links below. As it takes time to compile and analyse the data from many different sources, this statistic publication is produced with a 2-year delay from the reporting year, meaning that this year’s inventory represents the reporting year 2024.

As part of our ongoing commitment to compliance with the Code of Practice for Statistics we wish to strengthen our engagement with users of air quality data and better understand how the data is used and the types of decisions that they inform. We invite users to register as a “user of Air Quality data”, so that we can retain your details, inform you of any new releases of Emissions statistics and provide you with the opportunity to take part in user engagement activities that we may run. If you would like to register as a ‘user of air quality data’, please provide your details in the linked form.

Please email us with your feedback to help us make the publication more valuable to you.
