'Living Green Walls' Lined With Trees and Bushes Could Help Reduce Toxic Pollution

Sourced from the Daily Mail

'Living green walls' that absorb pollution could soon be built along major commuter routes around Birmingham.

Structures in the city lined with trees, bushes and other greenery would deliver cleaner air at the roadside according to new plans.

It is estimated that 900 deaths a year in Birmingham are linked to air pollution through conditions such as heart disease, lung disease and cancer.

The plans, put forward by Birmingham Conservatives ahead of the May 3 UK local elections, suggest lining the city's 'urban canyons' with green structures.

Urban canyons are confined areas of a city that are flanked by high walls of concrete or glass, such as busy roads.

Because pollution cannot easily escape street canyons, lining them with green walls of grass, climbing ivy and other plants could filter out dangerous particles.

One Birmingham Conservative councillor said the walls could remove 40 per cent of nitrogen oxides and 60 per cent of particulate matter from the surrounding air.

Exposure to these pollutants has previously been linked with a higher chance of cancer and heart attacks in adults, as well as lung problems in children.

Plans for green walls in Birmingham would dip into a £500 million ($700 million) pot of national funds to improve the city's green infrastructure.
