A new campaign is looking to dish out thousands of pollution-monitoring tags to schools and sports clubs in a bid to create a hyper-local air map of the capital.

The launch comes during a year where it was revealed that south-east London is particularly affected by the big smog.

A report revealed that eight primary schools in Greenwich borough were in areas with “illegal” levels of air pollution in 2010.

Separate figures indicated that Bromley borough has the second-highest death toll from pollution of all the London boroughs.

In June, a Hither Green mum called for Mayor of London Sadiq Khan to start an inquiry into the impact of pollution on child asthma after her nine-year-old daughter died from an extreme attack.

Schools and community groups can register through the Map London website to get CleanSpace Tags - personal smart sensors which compile detailed data on air pollution levels.

Individuals can monitor their personal exposure to air pollution, and if enough groups take part, Drayson Technologies hopes to create a hyper-local map of London's pollution levels.

Lord Paul Drayson, who is chairman and CEO of Drayson Technologies, said:

"London is in the midst of an air pollution crisis, but by equipping people with CleanSpace Tags we can empower them with information on the air around them.

"We’re helping them avoid pollution hot spots on a street-by-street basis, whether it’s around their school, local park or hospital."

Dr Penny Woods, Chief Executive of the British Lung Foundation, said: 

"It’s great to see companies using innovative ways to track air quality in areas where people live, work and study.

"Poor air quality, particularly concentrations of diesel pollution of the kind seen in many busy city locations, can seriously affect people’s health - especially if you have a pre-existing lung condition or are a growing child.

"The important question is, what do we do with this information? We would urge public and private companies to work together to control and reduce pollution levels to improve all our health."
