Air Quality Monitoring

This section provides access to air quality monitoring data and reports for Sussex.

Peak hourly readings from each site and a graph showing pollution levels over the last seven or thirty days.

Local Authorities are required to assess and report every year to the government on the air quality in their local area. The reports must assess whether the statutory health-based objectives are being met. Where the objectives are not being met a Local Authority has to produce an Air Quality Action Plan to improve local air quality. ​

Air Quality & Health

Sussex-air is a partnership, set up in 2000, comprised of officers from all the Local Authorities in Sussex.

The partnership has a set of terms of reference but is not a formally constituted body.

Good Air Quality is fundamental healthy living and ensuring our emissions to air do not impact on the environment as well. By reducing pollutant emissions we are also helping to fight Climate Change and deliver a more sustainable lifestyle. 

It is estimated that long term exposure to man-made air pollution in the UK has an annual effect equivalent to 28,000 to 36,000 deaths (Public Health England – Nov 18).
