Air quality

Air quality

Under the Environment Act 1995, we are required to regularly review and assess air quality within our area against national air quality objectives for key pollutants.  

The pollutants for which air quality objectives exist are:

  • Nitrogen dioxide 
  • Sulphur dioxide
  • Benzene   
  • 1, 3 - butadiene
  • Carbon monoxide
  • Lead
  • Particulates

A review of the Local Air Quality Management by central government placed focus on assessing and taking action on three pollutants in particular:

  • Nitrogen dioxide
  • Particulates 
  • Sulphur dioxide

We produce annual reports on the state of air quality within the city, which now also provide updates on any action plan measures.

In order to keep a check on air quality, we maintain a number of monitoring sites for nitrogen dioxide and particulates throughout the city.

For areas in the city where the air quality is not likely to meet the required objectives we have to declare an Air Quality Management Area (AQMA). We then produce an action plan that seeks to identify ways in which the air quality can be improved within that area.

Taking action

We first completed a review and assessment of air quality in 2002, which resulted in an AQMA being declared as it was discovered that the levels of nitrogen dioxide were likely to exceed the annual mean air quality objective. This order was amended in February 2014 to include reference to the hourly mean objective due to the likely breach of this additional objective on parts of Broadgate. 

A detailed air quality assessment in 2007 identified that the level of particulates were likely to exceed the national objectives. This meant that an AQMA for particulates was declared at the end of February 2008.

The main source of both nitrogen dioxide and particulates within the city is road transport.

You can download copies of the Air Quality Management Area Orders and associated maps of both the AQMAs from the downloads section on this page.

Air Quality Action Plan 

We produced an Air Quality Action Plan in 2006, which outlines a number of potential measures that may be taken to improve air quality. As the majority of the proposed actions are aimed at trying to reduce the impact from road transport, the action plan has been incorporated into Lincolnshire County Council’s current Local Transport Plan through the Lincolnshire Strategic Air Quality Partnership. 


Information on air quality can be obtained by contacting the Pollution Control Team or by reviewing the latest reports in the downloads section.
