Green Light: Low Emission Neighbourhood

Westminster City Council has been awarded a grant from the Mayor of London’s Air Quality Fund for the Marylebone Low Emission Neighbourhood.

Marble Arch London joined forces with the City Council and a range of other local partners to bid for £1m to create the low emission neighbourhood (LEN) in Marylebone.

The LEN will stretch from George Street in the west to Marylebone High Street in the east. Marylebone suffers some of the highest pollution levels in London, given the area’s location, mix of land uses, building density and type, and number of vehicle trips. Its location between major transport routes results in a complex urban air quality problem with levels of nitrogen dioxide (NO2) that exceed recommended health levels and very high levels of particulate matter.

Funding will unlock innovation and pilot schemes that can be replicated elsewhere in London, including:

  • creating a new building energy efficiency scheme
  • increasing patrols by ‘Air Marshals’ to enforce no engine idling
  • improving the public realm and creating greener spaces
  • introducing play streets for families to enjoy
  • vehicle delivery plans to reduce traffic

Partners include our neighbours Baker Street Quarter Partnership and New West End Company, together with residents’ association The Marylebone Association, The Marylebone Forum and The St Marylebone Society. Delivery partners include Q Park, UPS and King’s College London. The Portman Estate, The Howard de Walden Estate, The Wallace Collection, Home House, Knight Frank, Sylvia Young Theatre School, University of Westminster, Monocle, The Royal Society of Medicine and St Marylebone Parish Church also pledged support to the application.
