Find out about air quality in Swindon

Local authorities are required by law to identify local air quality problems and to take action to tackle them.

Air quality has improved significantly in recent decades. Since 1970 sulphur dioxide emissions have decreased by 95%, particulate matter by 73%, and nitrogen oxides by 69%. Total UK emissions of nitrogen oxides (NOx) fell by a further 19% between 2010 and 2015. However, poor air quality persists in certain areas of the country and continues to affect human health and our environment.

The Government published the UK’s plan for reducing roadside nitrogen dioxide concentrations in May 2017, setting out its approach to meeting the statutory limits for nitrogen dioxide (NO₂). In May 2018, the Government published a draft Clean Air Strategy for public consultation until mid-August 2018. This outlines the Government’s ambitions to reduce air pollution in the round, make our air healthier to breathe, protect nature and boost the economy. The draft strategy aims to set a direction for future air quality policies and goals.

It includes a proposal to introduce new primary legislation which would give local government new powers to improve air quality. You can find more information on air pollution and how it affects us all at the Government’s air pollution explainer page. The pollutants and their main sources in the UK are:

Pollutant Main source
Nitrogen dioxide (NO₂) Nitrogen dioxide (NO₂) is one of a group of gases called nitrogen oxides (NOx). Diesel light duty vehicles (cars and vans) are the largest source of  nitrogen dioxide emissions
Particulate matter (PM₁₀) Much of the PM in urban pollution hotspots, particularly those close to roads, can come from traffic sources
Sulphur dioxide 46% of total sulphur dioxide emissions come from the power generation sector
Non-Methane Volatile Organic
Compounds (NMVOCs)
Industry, both large and small, is responsible for 71% of VOC emissions
Ammonia (NH₃) Farming is the biggest source of ammonia emissions (81%)

Air quality management areas

Local authorities are responsible for managing air quality, working with local stakeholders. We review and assess air quality in our area to determine whether we are likely to achieve the targets set out by Government.

If we think we will not meet a target, we have to declare an Air Quality Management Area (AQMA) covering the part of the borough where the problem lies. We must then draw up an air quality action plan stating how we will aim to meet the targets, consulting neighbouring local authorities, businesses, local people, the Highways Agency, the Environment Agency and others.

In a paper agreed by Swindon Borough Council’s Cabinet in February 2018, Kingshill Road area was declared an Air Quality Management Area (AQMA). This was because regular monitoring of Nitrogen Dioxide (NO₂) in this location, the most common pollutant, indicates that this location is currently in breach of the annual average air quality objective of 40μg/m3. The Council issued a media release on 2 February 2018.

An Air Quality Management Steering Group has been established to develop and oversee the implementation of the Air Quality Action Plan for Swindon along with working to improve air quality across the borough. The Council will formally consult on a draft Action Plan by the end of 2018.

To inform the development of the draft Action Plan, the Council organised a public meeting on 19 September 2018 for local residents to find out more and share their ideas.

Over half of all local authorities in England have declared AQMAs. This interactive map shows where they are across the UK and which local authorities have declared AQMAs.
