Hackney and Islington councils are leading the way against air pollution with the UK’s first scheme banning all but the cleanest vehicles from two zones in Shoreditch and Bunhill.

Petrol, diesel and older hybrid vehicles will not be allowed to enter 9 streets during peak times. Ultra-low emission vehicles like electric cars, e-bikes, the newest hybrids and hydrogen vehicles, as well as pedestrians and cyclists, will be allowed.

LEN Prisms and Green Screens

To alert drivers that they are entering the ULEZ, Meristem were asked to design, install and maintain a series of 3m high LEN Prisms and Green Screens across various entry points.

These gateways are SuDS (Sustainable Drainage Systems), storing and re-using surface water, decreasing flow rates to watercourses and improving water quality by removing pollutants.

They also add vital greenery to a grey area. The ivy and base planting will suppress dust and air borne pollutants, reduce noise pollution and improve the surroundings for local residents and businesses.

Councillor Feryal Demirci, Hackney Council’s cabinet member for neighbourhoods, transport and parks, said: “The streets around Shoreditch suffer from some of the worst air quality in London.

“Ultra low emission streets will have reduced levels of air and noise pollution, make it easier and safer to walk and cycle and improve the character of the area for all residents and businesses.

“Our ultimate goal is to reclaim the streets from polluting motor vehicles – this groundbreaking scheme is the first step towards doing that.”
