Why is it important to breathe clean air?
It is important for our health that the air we breathe is clean. Air pollution is particularly damaging to:
- children’s lungs as they are still growing
- unborn fetuses of pregnant women
- the elderly
- those with breathing or heart problems
How do we measure air pollution?
In the UK, air pollution is measured in μg/m³. We work to National standards, and if air pollution exceeds 40μg/m³ continuously as a mean annual average, an Air Quality Management Area (AQMA) is declared, requiring an Action Plan to reduce pollution.
What areas don’t meet the National standards in Colchester?
Until 2023, much of the city center was an AQMA. However, due to improved air quality, the AQMA has been reduced to specific areas: the narrow end of Brook St, Mersea Road at St Botolphs roundabout, and Osborne & St Johns Street.
What causes the air pollution in Colchester?
In Colchester, the primary source of pollution is from vehicle exhausts and in the city centre the narrow streets with buildings close together means the pollutants become trapped (and can’t disperse into the surrounding air). That’s why it’s important to encourage people to choose less polluting and healthier travel options.
What is Colchester City Council doing to improve the air we breathe?
The Department for Environment, Farming and Rural Affairs (DEFRA) requires Colchester City Council to have an action plan to tackle air pollution. This plan encourages residents and businesses to choose alternative transportation methods, promoting walking, cycling, and public transport. Many projects are community-driven or community-supported.
What feedback would you like from me?
Colchester City Council seeks your views on the importance of clean air, thoughts on the current action plan, and ideas for future projects. The World Health Organisation guidance recommends air pollution levels be no more than 10ug/m³ to reduce health risks. Would you continue to support further air quality improvements after we have met the National standards
