Air Quality and Planning


Although air pollution in London is generally associated with road traffic, it is estimated that 38% of nitrogen oxide emissions in the City come from boilers, CHP and diesel generators (which also contribute to particulate levels).

In addition, deconstruction and construction activities can contribute negatively to air quality if not appropriately managed. New and refurbished developments can therefore reduce their impact on air quality and reduce exposure through:

  • appropriate development design, layout and energy efficiency
  • appropriate site management during deconstruction and construction
  • the installation of low and zero emission technology

Air Quality Supplementary Planning Document (SPD) - Consultation

So developers can minimise emissions and exposure to air pollution in the Square Mile, the City Corporation has produced its first Air Quality SPD (50KB) which is in its 8 week consultation phase. Paper copies of the SPD are available in City libraries and at the Guildhall planning desk.

The SPD provides City Corporation detailed guidance relating to the GLA's London Plan Air Quality Policies and the City Corporation's Local Plan Air Quality Policies

The consultation ends on 31 March 2017 and an Equalities Impact Assessment (200KB)and Strategic Environmental Assessment Screening Statement (60KB)​ have been produced which demonstrate the SPD has a largely neutral or positive impact.

Consultation responses

Air Quality SPD consultation responses can be sent to

Additional City Corporation SPD's and consultations can be found on the Supplementary Planning Document webpage.

Also see the Chimney Emissions' webpage for Clean Air Act and emission reduction guidance.​

​Minimising impact during Deconstruction and Construction - Code of Practice

The City Corporation has produced a Code of Practice for Deconstruction and Construction (1MB). There is a dedicated air quality chapter which incorporates City Corporation and appropriate GLA requirements.

The City Corporation's Code has recently been updated and will be available for consultation in the near future. The update includes the requirement for appropriate Non Road Mobile Machinery engines to meet the Euro Stage IIIB requirement and to be registered on the dedicated NRMM website.
