Air quality monitoring
All local authorities have a legal duty to out to carry out annual reviews of air quality in their area.
Pollutant levels are reviewed and assessed against government air pollution objectives set out in the national air quality strategy. These pollutants are:
- Carbon Monoxide
- Nitrogen Dioxide
- Sulphur Dioxide
- Particulates (PM10)
- 1, 3 - Butadiene
Areas identified with pollutant levels that may be at risk of going above the objectives are declared as Air Quality Management Areas (AQMA).
Annual reports are published showing changes in air pollution concentrations and progress towards achieving the national air quality objectives.
Norwich air quality stations and live measured pollution levels
There are two static air quality stations in Norwich.
The council owns and operates the Castle Meadow air quality station which measures oxides of nitrogen (NOx, NO and NO2) and particulates (PM10 and PM2.5). This is an urban roadside site and live data can be found at the Norfolk Air Quality website.
There is also an urban background site owned and operated by DEFRA located at Norwich Lakenfields. This station measures oxides of nitrogen (NOx, NO & NO2), particulates (PM10 & PM2.5) and ozone (O3). Information and live data for this site can be found on the UK Air website.

Greater Norwich Growth Area Air Quality Pledge
Norwich City Council is committed to working with the three other local authorities within the Greater Norwich area — Norfolk County Council, Broadland District Council and South Norfolk District Council — to tackle ways of reducing the impact of traffic emissions on air quality.
Open fires and wood burning stoves
The use of open fires and wood-burning stoves has risen in popularity over recent years. This means that we are seeing more smoke from chimneys which has a negative effect on air quality. This can cause breathing problems such as asthma attacks and contribute to other health conditions.
The Department for Environment Food & Rural Affairs (DEFRA) has provided a simple Guide to open fires and wood burning stoves to reduce environmental and health impacts.
